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!

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!

Edging and Trimming

Edging and trimming the lawn is like having a manicure after cutting your fingernails. It smooths out any roughness and adds an elegant finishing touch to your landscape, and everything is just more perfect! But which lawn care activity is which, and how do you do them properly to give your lawn that manicured look?

Edging or Trimming – Which is Which?

Before you pull out the lawn tools, it’s important to know which activity you need to do to create the look you want.

Edging
When you are edging, you define the line between a hard surface (sidewalks, driveways and curbing) and a growing area such as a flower bed, garden or lawn. To achieve this, a vertical cut is made between the two using a spade or edging tool. Some have mastered the art of using the string trimmer to do this. This creates a crease-like separation between the organic (growing) and inorganic (non-growing) surfaces. Properly done, edging will help minimize weed growth in these cracks and crevices and gives the landscaping a smooth, formal appearance.

Trimming
Trimming removes the grass, weeds and other plants from areas a lawnmower can’t reach. Long wisps of grass along the side of the house, fence or other structure aren’t very attractive, and trimming them away will give a finished, uniform look to the landscaping. Most people use a string-trimmer or bladed trimmer for this work, but hand shears also do the job. Trimming is also often done around trees or in tight corners where a lawnmower is less effective.

When to Do Edging and Trimming

How often should trimming and edging be done? This depends upon your own personality. Some people feel edging and trimming is a requirement of every mowing. Others do edging and trimming every third or fourth time they mow, or whenever it may look necessary to give the lawn and landscape a uniform look.

Edging and Trimming Tips

No matter how often you choose to do edging and trimming, it is important to do it effectively!

Use only the proper tools for these landscaping tasks. This will help prevent injuries or strain on your hands, wrists and elbows, and will get the job done more quickly and efficiently.
Check edgers and trimmers regularly to be sure they are sharp, well-oiled and in good functioning condition. Keep extra string for a trimmer on hand so you can quickly replace the spool when it runs out.
Always practice good safety measures when edging and trimming. Wear safety goggles if there is risk of flying debris (as there often is), and keep the tools away from children and pets.

For many people, edging and trimming is all part of good lawn maintenance. Once you know the differences between them and how to do them well, you’ll be amazed at the difference these tasks make to the beauty of your lawn.

General Soil Amendments

We’ve all heard of the importance of amending the soil properly for gardening and landscaping, but the number of soil amendments sold in garden centers often confuses gardeners. Which is which, and which will work best for your soil conditioning needs?

Types of Soil Amendments

Soil amendments fall into two basic categories, inorganic and organic. Inorganic amendments come from non-living materials such as sand, perlite, vermiculite and crushed stone. With the exception of limestone and gypsum, which are used to increase soil calcium, these are not commonly used in the garden.

However, organic amendments are the opposite. They come from previously living materials such as peat, manures and composts. When leaves, bark, peat, animals and animal wastes are mixed together to decompose, compost or “humus” is the final product. Very commonly used, these materials enrich the soil by increasing the air spaces, adding extra nutrients to the soil, improving the absorption of those nutrients and increasing overall soil fertility.

Why You Need Soil Amendments

Excellent soil is not common around most homes. Even if it was initially, house construction and roadwork often removes the good soil and construction equipment compacts the remaining soil. Furthermore, heavy use of the remaining turf – children and pets playing, for example – continues to compact the soil. Chemical treatments, runoff from gutters and downspouts, removal of existing plants, changes in local wildlife – all of these factors can wreak havoc on soil.

Adding organics loosens compacted soil and results in better gardens. Incorporate organics into the beds throughout the year by working evergreen needles, leaves and lawn clippings into the soil. Amendments such as peat or lime can improve a pH problem, if one exists. Calcium and magnesium deficiencies can be corrected using organic materials such as bone meal or wood ashes, or inorganic materials such as limestone, gypsum or soft rock phosphate.

Mulching is another simple way to add biodegradable materials to the soil. Simply place mulch around the plant, leaving several inches bare closest to the stem to discourage insect invasions and rot. In addition to slowly providing nutrients as it decomposes, mulching is attractive, reduces weeds and erosion, maintains soil temperature and prevents “crusting” that occurs when soil becomes too dry.

Another advantage of adding organics is the attraction of worms. They further assist in the decomposition, increase aeration and leave worm castings, a valuable organic material, behind. A healthy garden is home to many worms, and it all starts with adding organic soil amendments.

Whether you opt for organic or inorganic soil amendments, if you use them properly, you soil will improve and your landscaping, flowerbeds and garden will look better than ever.

Fungus Gnats

Have you noticed little black gnats flying around your houseplants or outdoor potted plants? These are probably fungus gnats. These can be a serious problem in commercial greenhouses holding thousands of plants but are easily controlled by homeowners who take appropriate steps for eliminating these pests.

What Fungus Gnats Need

As weak fliers, fungus gnats live in and around damp decaying material. Plants with fungus gnats are usually being overwatered. This is the primary cause for an increase in the gnat population, as they thrive in wet, organically-rich soil. Gnat grubs nibble on the tender roots of houseplants, but they do not generally do enough damage to severely harm the plant – they are more of a nuisance as they mature and fly around the plant. These gnats do not bite, but they can be annoying. When an infestation is bad, they can quickly spread from plant to plant, making them even more challenging to control.

Ways to Control Fungus Gnats

Letting a plant dry out between watering will decrease the decay and fungus in the soil, making the pot less hospitable for fungus gnats. Always make sure pots have adequate drainage and that water is not left standing in saucers. Adding a porous top-dressing, such as sand or gravel, to the pot can also help water drain away from the surface so the gnats cannot burrow down to the organic richness they crave.

For home use, insecticidal sprays with Pyrethrins are available and can be used against fungus gnats. If treating a houseplant, be sure to take plants outside and follow label instructions carefully, keeping the chemical away from children and pets at all times. Bacillus thuringiensis (BT), a biological control, will also provide relatively fast control killing the larvae in the soil.

For houseplants, the easiest and fastest remedy is often the best. Repot the infested plant using new potting soil into a pot with drainage. Carefully rinse the plant’s roots while repotting to remove as much soil as possible, and be sure the new pot’s hole is not clogged. Prune away any dead roots, leaves and stems. The gnats will be gone immediately.

To keep fungus gnats from returning, carefully check a plant’s moisture before watering to prevent moisture problems that can bring fungus gnats back in a flash. Water monitors can be used, or simply check that the top 2-3 inches of soil is dry before watering. Using watering bulbs or other waterers that are inserted deeply into the soil can also keep fungus gnats at bay by providing water directly to the plant’s roots, without saturating the entire pot.

Fungus gnats certainly aren’t fun when they infest your plants, but fortunately there are many ways to keep these bugs under control or eliminate them entirely. Using several techniques at once will be most effective, and the gnats will be gone just as fast as they first appeared.

Spider Mites

Spider mites are one of the most common pests in landscapes and gardens and feed on many fruit trees, vines, berries, vegetables and ornamental plants, as well as houseplants. These tiny mites are just large enough to be seen with the naked eye, but may just look like tiny, moving dots. For tiny creatures, they can do considerable damage to plants if left unchecked.

How Spider Mites Hurt Plants

Spider mites cause damage by sucking cell fluids from plant leaves. A small number of mites usually isn’t a reason for concern, but plants can sustain heavy damage if populations are high and the infestation spreads. You may notice a stippling of light or yellowish spots on affected leaves and often the webbing of mites can be seen on leaves and stems. As the damage continues, leaves may turn completely yellow, dry up and fall off the plant.

Controlling Spider Mites

Spider mites reproduce rapidly in hot, dry weather, therefore, keeping plants well watered is a good deterrent to heavy infestations. There are also many natural enemies to these pernicious bugs, such as lacewing larvae and some lady beetles that help to keep mite populations under control. Cultivating these helpful insects may be all that is necessary to minimize spider mite activity unless the infestation has already increased and spread.

Because spider mites are too tiny to pick off infected plants, judicious pruning or trimming of infested plants can help remove these pests. In heavy infestations, it may be necessary to discard an entire plant to take the mites with it. Do not put these clippings or removed plants in compost piles, however, or the mites will continue to thrive and will return to healthier plants.

At times, it may be necessary to use chemicals to deter spider mites. Be careful when using broad spectrum insecticides, however, as these will kill any beneficial insects as well as the spider mites, which can disrupt the delicate balance of a garden’s ecology. Simply spraying plant leaves with a blast of water, taking care to spray the undersides as well, can help to reduce mite populations by physically removing the spider mites. Insecticidal soaps and neem oil are also good choices when dealing with spider mites.

Once the mites have been removed, damaged plants may look bedraggled, but they will generally recover within a season or two, especially if the pests were recognized and treated quickly. Don’t let spider mites catch you in their webs – get rid of them today!

Top 10 Disease-Resistant Crabapples

Crabapple trees in flower are a sight to behold. They are the showstopper trees of spring, and are compact enough to fit in nearly any size, shape or style of landscape. But how will you pick the variety that is best for you?

About Crabapples

The unrivaled spring beauty of these trees can take your breath away, as they frequently bud in one color but the flowers open in another, which can create a glorious variegated effect. To add to their appeal, they perform again in the late summer or fall with a fabulous display of hanging, showy fruit that wildlife loves.

Crabapples are available in a range of flower petal colors that include white, pink, red and all shades in between. Flower forms may be single or semi-double with some varieties being fragrant. Selections may be made for fall fruit size and color, including shades of green, yellow, orange, bronze, red and purple. Crabapple trees are also available in a variety of leaf color, size and growth habit to accommodate a landscape of any style and size.

Crabapple Problems

Although these trees have the potential to be stunningly beautiful, crabapples are subject to a number of serious diseases that can leave them unattractive through most of the growing season. The four main offenders are…

Apple Scab: This disease manifests as unsightly dark lesions on the leaves and fruit and will cause premature leaf drop.
Cedar-Apple Rust: This blight presents as yellow spots on the upper side of the leaves early in the season, followed by orange rust spots on the underside of the leaves in the late summer. This disease will cause premature leaf drop.
Fire Blight: This infection gives new shoots the appearance of being scorched by fire and the fruit will look dark and shriveled.
Powdery Mildew: This common disease will cause the leaves to be deformed and give them a white, powdery appearance.

There is, however, good news. You can plant a crabapple today without hesitation, because we carry crabapple selections with an excellent degree of disease resistance.

Top 10 Fool Proof Houseplants

Do you have a “black thumb”? Do you love houseplants but just can’t seem to keep them alive no matter what their species or condition? Are you worried about getting new plants because being in your home is a death sentence for anything green? Worry no more! This list of foolproof houseplants will help you select and grow houseplants with confidence. Although all plants look and grow better with optimum care, these plants are some of the toughest you can find and will tolerate more abuse and neglect than most others.

Cast Iron Plant / Bar Room Plant (Aspidistra elatior)
Chinese Evergreen (Aglaonema hybrids)
Cordyline (Cordyline fruitcosa)
Dracaena (Dracaena spp.)
Jade Plant / Friendship Tree / Money Plant (Crassula ovate)
Mother-In-Law’s Tongue / Snake Plant (Sansevieria trifasciata)
Peace lily (Spathiphyllum cochlearispathum)
Philodendron (Philodendron spp.)
Pothos (Epipremnum aureum)
Spider Plant / Airplane Plant (Chlorophytum comosum)

Good Care Basics

While these tough plants can withstand some neglect, it isn’t as hard as you may think to provide them with proper care. No matter what type of houseplant you choose, some good rules of thumb that can help keep them happy include…

Position plants in a brightly lit room, but out of direct sunlight that can cause burns on the foliage. If the plant is stretching toward the window – turning to face the light – it can use more sunlight.
Use good quality potting soil appropriate to pot plants, and fertilize them regularly to provide adequate nourishment. Reduce fertilizing during the winter months when growth naturally slows.
Water plants regularly, but allow the top 2-3 inches of soil to go dry between waterings. The pot should have drainage holes, and never let a houseplant sit in a saucer of water – that can lead to root rot.
Group pots together to increase the humidity around the houseplants and reduce the yellow tips of leaves (a sign of dryness in the air). Use a wet pebble tray or mist plants to raise humidity as well.
Dust plants 1-2 times per month to keep their leaves bright and pores clear for better gas exchange. Be gentle, however, and do not use waxing sprays or other dusting chemicals on houseplants.

It can be a great joy to have houseplants thriving in your home. No matter how many plants you may have killed in the past, you’ll soon be a successful houseplant gardener when you choose plants that don’t mind kind-hearted abuse!

Determinate Versus Indeterminate Tomatoes

It’s tomato-planting time again! If you’ve grown tomatoes in the past, you most likely have your favorites. If not, just ask! You’ll find some pretty strong opinions regarding tomato choices, and every gardener has their own top choices, must haves and great picks for tomatoes.

Choosing Tomatoes

Along with soil type, climate, moisture and other typical gardening considerations, one of the features you will need to take into account when choosing what type of tomato to grow is plant habit. The two main habit classifications are “determinate” and “indeterminate” and are based on fruit use, available growing space and length of growing season. Both habit classifications include fruit selections in a wide variety of colors, sizes, shapes and tastes.

Determinate Tomatoes

Tomatoes from a determinate plant are produced earlier in the growing season, on terminal ends of a compact bush. This type of tomato generally reaches 3-4 feet in height and is easily supported with a tomato cage or may even be self-supporting. Due to its compact habit, it may even be grown in containers, ideal for gardeners with less available space. Because all the fruit ripens at the same time, determinate tomatoes are an excellent choice if you plan to can your fruit or make sauce, as you won’t need to worry about collecting enough fruit to work with. Determinate classification includes popular tomato varieties such as:

“Celebrity” – an eating tomato
“Roma” – a paste tomato
“Patio” – a dwarf selection
“Baby Cakes” – a cherry tomato
“Carolina Gold” – extra large, yellow fruit

Indeterminate Tomatoes

Indeterminate tomato plants will fruit along the entire length of the stem over a longer period of time, in fact continually, until frost. Smaller amounts of fruit ripening regularly throughout the growing season makes an indeterminate tomato plant an excellent choice if you cannot cook or consume a large quantity of this perishable fruit all at one time. Indeterminate tomato plants are vines, requiring proper pruning and support, to reach their ultimate height of 8 feet or more. Indeterminate classification includes popular varieties like:

“Amish Paste” – heirloom, paste tomato
“Beefmaster” – extra large sandwich tomato
“Better Boy” – juicy but firm, compact vine with shorter internodes
“Black Krim” – deep color, rich flavor
“Chocolate Cherry” – cherry, chocolate red in color

By understanding the differences between these basic tomato classifications, it will be easy for you to choose the tastiest tomato to suit your gardening needs and harvest preferences. Many gardeners choose more than one of each type of tomato, ensuring there is always a bountiful supply to use, to share and to enjoy!
