New Shrub Raspberries

Rejoice! You no longer need hedgerows, trellises or complicated stakes to grow succulent raspberries. You won’t need armor-like gloves either. Now you may grow thornless raspberries in your garden or in containers on your patio, deck or front porch.

Introducing Raspberry Shortcake™

Developed in Oregon after decades of intense breeding for the most desirable plant characteristics, Raspberry Shortcake™ (Rubus idaeus ‘NR7’) is the first truly dwarf raspberry. Growing just 2 ½ to 3 feet tall with a compact, mounding shape, it is covered with full-sized sweet raspberries from mid-summer through fall. Deciduous in the winter, it produces new canes in the spring to bear even more fruit. It is self-fertile so does not require multiple plants to bear fruit, but its size, appearance and juicy berries are too good to plant just one.

Planting Your Raspberry Shrub

Well-drained, rich soil produces the best and most abundant fruit from these shrubs, and neutral pH (7.0) is preferred. If planting in a container, be sure to use a potting mix especially for containers to ensure adequate nutrition to the plant. If planting in the landscape, choose a location in full sun with moderate room suitable for some spreading, such as bordering a hedge or along a walkway that will help guide the growth and expansion. Water regularly for plump, juicy berries. A well-balanced fertilizer in early spring and summer increases plant vigor and production.

Pruning is simple, just remove the oldest canes after fruiting and enjoy the fruits on the new ones in spring. Avoid trimming away new growth, or you may miss out on future harvests, but any dead canes can easily be pruned away to keep the plant healthy and productive, as older canes will not produce new fruit.

Protecting Your Berries

It is important to note that these berries can be just as irresistible to birds and other backyard wildlife as they are to gardeners of all ages and abilities. To protect the berries so there are some left for you to enjoy, it may be necessary to use netting or other types of covers over the shrubs after the berries first appear in the summer. After the fruiting is finished, the covers can be removed.

Raspberry Shortcake™ is so simple, safe and easy, it doesn’t matter what color your gardening thumb may be, what experience you have harvesting berries or even if you’ve never grown anything to eat before – even young children can grow and harvest these mouth-watering raspberries with ease!

Growing Mint in Your Herb Garden

Many of us love mint. With many different flavors of mint available at garden centers, it is easy to want to plant one of each. Planning ahead makes this possible to do, but lack of planning may have you tearing them all out.

How Mint Grows

Mint grows as a groundcover. The underground runners spread quickly and are difficult to remove if containment is desired. In other words, mint is often considered invasive and can quickly take over flowerbeds, vegetable plots and even areas of turf near where it is originally planted. Planting in pots placed into the ground prevents its escape, or intensive labor may be needed to help get mint back to its original proportions after it has wandered.

Planting Mint

To help keep mint under control and more accessible for use, many gardeners opt to plant it indoors. Attractive in barrels or pots by the kitchen, mint leaves and flowers can be easily available for cooking or beverages.

To prevent plants from looking rangy, frequently cut or pinch back new growth. Pinching off the flower buds produces more lush leaves and fuller plants.

Mints grow well in sun or part shade, preferring well-drained but moist soil. Although not particular about soil type, enriching clay soil with compost will improve the overall plant appearance and taste. Different soil pH values and organic compositions may also have some minor influence on the taste of different mints.

Most mints grow 18-30 inches tall. Plant at least 2 inches apart to prevent cross-pollination of different varieties and preserve the best flavors. As a perennial, the plant may disappear in the winter, but will return in spring, hardier and more vigorous than ever.

Using Mint

It’s no surprise that mint is an edible favorite. Not only is it popular for refreshing drinks such as mint juleps or mint-infused lemonade, but it is also ideal for…

  • Sauces
  • Salads, especially fruit salad
  • Flavoring for cookies, cakes and puddings
  • Jellies and preserves
  • Smoothies
  • Soups and stews
  • Ice cream, gelato and frozen yogurt
  • Garnishes on meats
  • Freezing in ice cubes for a drink garnish

Mint can be used fresh for a strong, vibrant taste, or it can easily be dried and used all year long. Both fresh and dried mint sprigs can also be fragrant additions to cut flower arrangements, wreaths or other greenery decorations as well. With so many wonderful options for mint, you’ll want to add some to freshen up your herb garden today!

Ornamental Grasses

Ornamental grasses can reduce your watering costs, lessen your mowing time and increase the interest level of your garden. No matter what your garden’s needs, there’s a grass to solve it. From short ground covers to tall bamboo, there’s something for every site.

About Ornamental Grasses

Generally defined as “a plant with narrow upright leaves growing from the base,” ornamental grasses come in different sizes, shapes, colors and with differing growing requirements. While they may be cut to the ground each year, they are not mowed regularly, and work well as borders, specimen plants or part of coordinated beds. When choosing an ornamental grass for your site, consider the following:

  • Size
    Some beautiful grasses are just inches tall. Others, such as bamboo, grow to 20 feet or even taller. A shorter grass is a perfect edge for a walkway or to border a flowerbed, while a taller grass provides screening or background height.
  • Deciduous or Evergreen
    The winter form of a grass can be very different from its summer form. Evergreen grasses do not die back in the winter, their form remains the same. Winter colors may change and provide interest. Deciduous grasses die back or lean over. Consider the plant’s use when choosing between deciduous and evergreen. If using a grass as a screen, deciduous may not be a good idea.
  • Running or Clumping
    Clumping grasses stay where they planted, and as they grow, the overall plant width increases. However, a running grass sends runners through the ground to grow another grass plant. Sometimes this can be up to 6 feet away. This is advantageous when using the grass as a groundcover or trying to fill in a larger area. Clumping grasses can be divided if they become too large for the site.
  • Color
    Ornamental grasses are available in many colors, including variegated shades with contrasting edges. Additionally, many grass colors change throughout the year. Blues, reds, greens, yellow and variegated shades work well in different situations. A gold or white-hued grass can brighten a dark corner, whereas a dark green grass may be a perfect backdrop for smaller colorful plants.
  • Growing Requirements
    Sun, water, wind and soil requirements vary among grasses. Some require full sun; others grow best in the shade. Some grasses are ideal in rain gardens or wet soils, while others thrive best in drought conditions. Some don’t mind a breezy location, while others need to be more protected. Some prefer a rich, organic soil, while others will look great even in poor soils. And, of course, there are grasses for every range in between.

Before going to the garden center to purchase an ornamental grass, make a list of your requirements. You may want a short grass to line a walkway in full sun with sandy soil. Alternatively, you may need a grass to fill a dry and shady corner. Perhaps you would like to watch a grass clump emerge in the spring, grow to 6′ tall, change colors through the summer and harvest dry seed heads for an autumn arrangement. Choosing the correct grass ensures the beauty of your garden for years to come.

Protect Your Japanese Maples

Beautiful additions to any landscape, Japanese Maples will look their best when given some protection during hot, dry summers. As the weather becomes hotter and drier, your these trees may show signs of heat stress with the development of crispy leaf edges or, as conditions get even more extreme, leaf drop. This diminishes their stunning beauty and shrivels their leaves, but fortunately, there are several ways you can minimize this problem no matter what the weather. From planting these trees in the right spot to mulching the roots appropriately to using anti-transpirants, you can shield Japanese Maples from drought-like conditions.

Protective Planting

When planting a Japanese Maple, choose a location that receives morning sun only and has some protection from strong winds. Full afternoon sun and windy conditions will quickly stress plants and reduce leaf color. Planting a Japanese Maple in front of a western or southwestern windbreak of conifers or other evergreens will provide good shielding, or plant these trees on the eastern side of the house, garage or other structure to provide that essential barrier.

Save Moisture With Mulch

Mulching will help to retain moisture and cool root zones to protect these trees. Apply 2-4 inches of mulch under your Japanese Maples, extending out to the drip line for complete protection. Be sure to keep the mulch several inches away from the tree’s trunk to avoid fungus problems and crown rot. Ideally, install a drip watering system or other slow-release watering under the mulch to retain the most moisture with less water lost to evaporation.

Anti-Transpirant Sprays

Another way to keep your Japanese Maples looking their best is to use an anti-transpirant to helps minimize moisture loss from leaves. The best time to apply an anti-transpirant is in early summer when Japanese Maples are in peak condition, before they start showing signs of suffering from heat stress. Make your applications early in the day or on a cooler, overcast day to avoid leaf burn. Apply monthly through the hottest part of the year and your beautiful trees will look gorgeous heading into the fall season.

Japanese Maples are popular landscaping trees and make stunning specimen plants in any yard, but they can be subject to heat stress that will reduce their beauty and vitality. By taking several steps to protect them, however, you can enjoy the beauty of these trees even when summers are hot and dry, and properly protected, your Japanese Maple will look brilliant throughout the summer.

Crape Myrtles

No yard or landscape should be without a crape myrtle, or two, or three or… many! How wonderful to have something that blooms so profusely during that time of year when most other plants are looking tired and worn from the summer heat and drought. The versatility of this plant makes it suitable for many types of yards and many uses, and once established, they will go on to add charm and delight to the landscape for many years.

About Crape Myrtles

Crape myrtles bloom in late summer and can be found in flower colors of pinks, lilac, white, reds and purples. Requiring very little maintenance once established, crape myrtles need a full sun location to thrive and they do not like wet feet. Keep these needs in mind when selecting a site to plant them. They will require some supplemental watering for the first year or so to get off to a good start and develop good roots. Crape myrtles are also pretty much pest-free, except for aphids on occasion and these are easily controlled with an insecticidal soap spray. Some varieties are more susceptible to powdery mildew than others but most of the newer varieties are more resistant to this fungus problem.

Planting Crape Myrtles

Although tolerant of a wide range of soil qualities, crape myrtles grow poorly in wet locations so be sure to select a well-drained planting site. Late spring to early summer is the best time to select and plant your new crape myrtles while they are actively growing and can settle in quickly. Plant at or slightly above ground level, spreading the roots out slightly and using mulch to protect and shelter the roots after planting. They do prefer a slightly acid soil.

Crape Myrtle Types

Crape myrtles can be found in shrub, multi-stem tree and single trunk tree forms. For best results select a cultivar whose growth characteristics and ultimate mature size fit your intended use. Planting a shrub- or tree-like crape myrtle in an area of limited space will require yearly pruning to keep it from outgrowing its place. Single- or multi-stemmed tree-form crape myrtles are ideal as flowering specimen trees or as small, flowering shade trees near patios, walkways and entrances. Shrub forms make an excellent accent in a shrub border when planted in groups. Dwarf plants are effective as large groundcovers, perennial bedding plants or container plants providing vivid, summer-flowering interest.

Pruning Crape Myrtles

If adequate room is provided, little pruning is required except to maintain shape or remove any dead or crossing branches. Remove any suckers or water sprouts to maintain tree forms and elegance. Blossoms are produced on new growth so you can prune anytime the plants are dormant through the winter.

With so much to love about these plants, there’s no reason not to add one to your yard this year! And next year, and the year after that, and the year after that…

Rose – Queen of the Garden

We all love roses. It may be the luxurious fragrances, rich colors or the elegant flower forms that attract us. It may be the memories that roses evoke. Whatever the reason, roses are one of the world’s most popular flowers. With so many different types of roses available, ranging from the diminutive miniatures to the towering climbers, there is no excuse to exclude this “Queen of Flowers” from your garden.

Rose Types

There are many types of roses to cultivate, and it can be difficult to choose. If you’re just getting started with roses, consider some of these popular favorites…

  • Hybrid Tea Roses: These blooms are a favorite of rose gardeners who enjoy long-stemmed, large flowers. Hybrid tea flowers have many petals and plants grow upright and tall, about 3-7 feet. These roses are appropriate in either a formal garden or informal planting.
  • Floribunda Roses: These roses have smaller flowers than hybrid teas with the flowers arranged in clusters. This rose bush is useful as a hedge for a border or privacy screen, and is equally stunning in mass plantings.
  • Grandiflora Roses: These beauties were developed by crossing hybrid teas with floribundas. This rose grows to around 10 feet tall so it should be used in the back of the border where its beauty won’t shroud other plants. The flowers of the Grandiflora are hybrid tea form and can be single stemmed or borne in clusters depending on the cultivar.
  • Climbing Roses: These roses make an outstanding vertical display when trained on arbors, walls, fences, trellises and pergolas and can grow from 8-15 feet tall. Flowers may be borne large and single or small and arranged in clusters.
  • Miniature Roses: These delicate nymphs are dwarf in every way – flowers, leaves and height. This rose may be mass planted as a ground cover, used as border or grown in containers on decks, patios and porches.
  • Shrub Roses: These flowers are renowned for their bushy habit and superior disease resistance making them an excellent choice for mass planting. The shrub rose flower may be either single or double. Some types have very showy rose hips.
  • Old Roses: These luscious heirlooms are making a come-back! Although bloom times and color choices are limited, old roses are much more fragrant, vigorous and disease resistant than modern roses. To obtain all the qualities of an old rose combined with a long bloom time of a modern rose, look for the David Austin varieties.

Not sure which rose is just right for your landscape or garden? Our rose experts will be glad to help you choose the perfect rose no matter what thoughts or emotions you want your garden to evoke. Stop in today to see the latest types of roses and the most popular cultivars for this year’s gardening.

Heavenly Hosta

Hostas are amazing plants, truly glorious with heavenly foliage that is stunning as a specimen or in mass plantings. The thin spikes of purple or white, trumpet shaped flowers appear for several weeks in the summer and are an added benefit to this divine perennial. But how much do you know about hostas, and which can you add to your landscape?

Phenomenal Foliage

Hostas are praised by many for their magnificent variety of leaf sizes, colors and textures. These angels will grace your garden with heart-shaped, lance-shaped, oval or nearly round leaves, and leaf sizes vary as well. Smooth, quilted or puckered textures, with either a matte or glossy sheen, add to the glory and hostas’ radiant glow.

The leaf margins can be either smooth or wavy and range in color from light to dark green. Foliage colors also include chartreuse, gray and blue, depending on the cultivar. Variegated hostas with cream, white or yellow margins will radiate in a dark area of your garden.

Where to Plant Hostas

While most hostas are shade worshippers, some types will tolerate sun, depending on the overall climate and moisture levels. Hostas remain attractive from spring until frost and can withstand a wide range of growing conditions.

As choice groundcovers or single specimens in the landscape, hostas are certainly divine. Some hostas are quite unusual and rare and may increase in value each year, especially as the plants thrive and can be divided and transplanted with ease.

Best Hosta Care

Little maintenance is required to care for hostas. Cut off old flower stalks after flowers have faded. Divide plants occasionally to increase their quantity. Keep an eye out for pests, especially slugs and snails that munch on the foliage.

Types of Hostas

With so many selections and varieties, you can find a hosta the will fit into almost any garden situation. The most popular options include…

  • Dwarf & Small Hostas: In addition to being planted in secret little pockets throughout your garden or next to paths, dwarf and small hostas can be used in difficult places. Plant them among tree roots, on a slope or terrace or in rocky places containing little soil.
  • Edger Hostas: These hostas are 12” or less in height and have more horizontal growth. They are able to control weeds as they leave no light, when well established, or room for weeds to grow.
  • Groundcover Hostas: This group of hostas grows to 18” or less in height. They do a great job in areas difficult to weed or maintain. If you are in need of a hosta for use as a groundcover, keep in mind it works great to plant spring-flowering bulbs among them. The hosta comes up after the show of flowers and covers the fading foliage of the bulbs.
  • Background Hostas: Selections from this group grow to 24” or taller at maturity. They can be used to increase privacy where you sit and relax or to provide definition to your property line as a unique hedge.
  • Specimen Hostas: Specimens may be any size. Choose a site close to where the plant will be viewed so that every detail (texture, color pattern, buds, flowers and fragrance) may be enjoyed.

Not sure which hosta is right for you? Come in today and let our landscape and garden experts help you choose the right heavenly hosta to add a bit of the divine to your yard!

Dwarf Evergreen Conifers

Dwarf conifers are some of the most versatile and popular plants of today’s modern garden and landscape. These fantastic plants add interesting texture, color and form to rock, pond and container gardens as well as any type of mixed border. They come in a variety of cultivars of different sizes and growth habits, and more cultivars are being introduced all the time. Dwarf conifers are virtually carefree and often provide four seasons of interest.

Dwarf Conifer Types

We commonly think of conifers as needled evergreens such as pines, spruce and firs, but not all conifers are needled and not all are evergreen. The common larch is needled, but deciduous. Ginko trees are conifers that have fan-shaped deciduous leaves, and this tree is neither needled nor evergreen. What identifies a plant as a conifer is that it is cone-bearing.

Dwarf conifers are slower growing and smaller versions of the straight species of a given conifer. A good example is the Eastern White Pine, Pinus strobus, which can reach a height of 100 feet at maturity. The dwarf version of this plant, Pinus strobus ‘Nana’, will only grow to eighteen feet at maturity, but other than its size, it shares all the charming characteristics that are so well loved about the full-size tree.

Thanks to their popularity, new varieties of dwarf conifers are being introduced each season. This gives you an almost endless selection to consider for your landscaping needs. Some of the most popular options include…

  • Abies alba ‘Green Spiral’ (Silver Fir)
  • Abies lagrocarpa ‘Arizona Glauca Compacta’ (Rocky Mountain Fir)
  • Abies procera ‘Sherwoodi’ (Noble Fir)
  • Abies balsomea ‘Nana’ (Dwarf Balsam Fir)
  • Cedrus deodora ‘Albospica’ (Deodar Cedar)
  • Chamaecyparis obtusa ‘Nana’ (Dwarf Hinoki Falsecypress)
  • Chamaecyparis obtuse ‘Nana Lutea’ (Hinoki Falsecypress)
  • Chamaecyparis pisifera ‘Aurea Nana’ (Japanese Falsecypress)
  • Picea abies ‘Little Gem’ (Norway Spruce)
  • Picea abies ‘Conica’ (Norway Spruce)
  • Picea abies ‘Pumila’ (Norway Spruce)

Growing Exotic Citrus

Citrus trees grown in fancy terra cotta pots, light-weight decorative containers or wooden planters can be used to adorn your garden, no matter how small it is. Use a potted citrus as a centerpiece for an herb garden, place several in a series on your steps or decorate your deck with these grand-looking accent plants. Dark, glossy green leaves look beautiful all season long while colorful, healthy fruit dangles enticingly from the branches. Although citrus plants are not winter hardy in the north, they may be moved indoors during this time. For added pleasure, citrus offers weeks of fragrant flowers in the spring.

Top Citrus Picks

There are several varieties of exotic citrus trees that can be stunning in the landscape. The most popular options include…

  • Calamondin Orange – This cross between a mandarin and kumquat produces miniature oranges that are somewhat tart but make excellent marmalade.
  • Ponderosa Lemons – Producing fruits that weigh up to a whopping 5 pounds each, Ponderosa Lemons have a thick ring with very little juice.
  • Variegated Pink Lemons – This lemon has variegated foliage and produces a yellowish-pink fruit.
  • Meyer Lemon – Although not a true lemon (it is said to be a cross between a lemon and either an orange or mandarin), the Meyer Lemon is one of the sweetest lemons.
  • Key Lime – Also known as Mexican Lime, this selection is highly prized for making Key Lime Pie. The plant is very thorny and produces small aromatic fruits.
  • Goliath Pummels – The largest of all citrus fruits, pummels taste similar to grapefruit.
  • Blood Orange – Having an unusual red flesh, these oranges are prized by gourmet cooks for their slight berry-like flavor.
  • Flame Red Seedless Grapefruit – This grapefruit variety produces medium-sized pinkish-colored fruits.
  • Cocktail Trees – These are a grafted tree that usually contains 4 to 5 different types of citrus on the same plant, great for your own fruit salad in minimal space.

Citrus Care

Place citrus plants in a sunny location where they will receive a minimum of 6 hours of sun to ensure the best possible fruit. Water regularly and feed with a fertilizer listed specifically for citrus plants every two weeks. During the summer months, citrus plants will produce a lot of new growth. In the early fall, before bringing plants indoors, prune citrus plants back about 1/8 of their existing size. This will help to minimize the shock that plants often experience when being moved. Use a humidity tray indoors or mist daily. Avoid placing your plant in a drafty area or by a heating vent. Provide a minimum of 6-8 hours of daily sun or very bright light in the winter months. It may be necessary to supplement with an artificial light source at this time of the year to keep the plant at its best.

It may seem unusual to have strange citrus trees in your yard or even right inside your home, but with a little care, you’ll be amazed at how much fun these plants can be to grow, and their sweet fruit is a wonderful reward for your efforts.
