All About Clematis

February 28th, 2017

Clematis are loved both for their ability to climb and for the lovely flowers they produce.

All you need to enjoy the beauty of clematis is to provide them with a minimum of 6 hours of sun, well-drained soil, and proper support, such as a wall, fence, trellis, rocks, tall shrub or another vine. Once these requirements are met, they are happy planted in gardens or in containers. If planted in full sun, keep a heavy layer of mulch around the roots.

Clematis grow best if these watering, feeding, and pest control instructions are followed:

  • Watering: For newly planted plants, keep the soil moist for the first few weeks. After that, watering only needs to be done during hot dry periods. Its better to do a deep soak rather than a few light waterings.
  • Fertilizing: Feed the plant with a fertilizer that’s rich in potassium. Look for a fertilizer that has an N-P-K ratio with the third number being the highest value. Feeding can be done each spring and fall.
  • Pest Control: Slugs are the main pest, and they can be kept away by putting down a slug barrier each spring. Sluggo® works very well.

Clematis plants require pruning, but how you prune depends on the variety and the planting location.  The amount of cutting and the correct time to prune is determined by when your clematis blooms and other factors, such as your preferred growth habit.  Some clematis bloom only in the spring, others later in the summer, and a third variety can bloom both early spring and late summer.  Once you’ve chosen which clematis is right for your growing conditions and bloom-time preferences, you’ll want to do some research to find the pruning method that fits your circumstances to ensure you get the maximum amount of blooms the next season.

With the proper care, your clematis will provide you joy for many years!

How To Grow Cucumbers

September 21st, 2015

Growing cucumbers from a trellis nettingCucumbers are a low-maintenance, high-yielding, low-calorie, nutrient-rich and scrumptious vegetable. Widely popular with home gardeners, cucumbers are one of the easiest vegetables to grow, with an assortment of selections adaptable to any gardeners space limitations.

Cucumbers When to Plant

Cucumbers are a warm-weather crop that, once established, should produce well into the fall. When putting out transplants, wait one to two weeks after your last frost date; seeds can be sown directly into the garden on your last spring frost date. You can find your average last frost date here.

Cucumbers Where and What Variety to Grow

To successfully grow cucumbers, you should choose a spot that gets at least 8 hours of sunlight daily and is easily accessible for watering. Once you’ve found the ideal location, space and personal preference will be the next factors to take into consideration. There are lots of cucumber varieties on the market:

  • Dwarf Cucumber Plants such as our Bush Crop Cucumber Plant, are the perfect cucumbers for container gardens or for very small garden areas. This is also a popular choice for schoolyard gardens. Their growth is more upright than vining, and they do not require a lot of space.
  • Semi-Dwarf Cucumber Plants such as our Fanfare Cucumber Plant, are also adaptable to container growing and will only take up a bit more space in your garden than a dwarf variety. They grow a little taller than vigorous varieties, but with vines about half the length.
  • Vigorous Cucumber Plants sometimes referred to as vining cucumber plants, will require the most room in the garden. Some vigorous varieties grow on vines reaching up to 6 feet (or sometimes longer) in length. The fruits are most often 8 to 12 inches long and will grow best upon trellises. Our most popular vigorous variety is the Garden Sweet Burpless Cucumber Plant.

Cucumbers How to Fertilize and Water

Cucumbers will grow best with adequate nutrition. Cucumber plants should be fertilized, preferably with an organic fertilizer, when first transplanted, again about a week after blooming, and then every 3 to 4 weeks afterwards. Use a low nitrogen fertilizer in order to avoid leggy, leafy, beautiful, but potentially fruitless vines.

Cucumbers also require consistent watering; inconsistent or negligent watering can result in bitter fruit. Water thoroughly two to three times a week, depending upon the climatic conditions in your area. Container plantings should be monitored closely and never allowed to completely dry out. Bear in mind that watering around the roots, as opposed to on the leaves, will provide the most efficient hydration to your vegetable plants and will help to prevent foliar diseases, mildew and leaf scorch.

Harvesting cucumbers from the gardenCucumbers When to Harvest

When choosing a variety, be sure to know the estimated number of days to maturity. Remember, this is just a guideline; Mother Nature may have her own agenda. Climatic conditions, soil health, moisture and disease can greatly affect your cucumber harvest in terms of time and yield. And, since cucumbers produce throughout the entire season, it is virtually impossible to gauge the number of days any specific cucumber has been on the vine.

Cucumbers at their peak will more easily separate from the vine when you harvest. If you really have to aggressively tug or cut the vine, you may want to wait a day or two. Its a good idea to wear gloves when picking cukes, as their skins and stems are covered with prickly spines that can usually be removed easily by simply wiping with a glove or cloth. Make sure the skins are smooth before serving!

Delaying harvest until a cucumber starts to turn yellow can result in bitter fruit. Though your cucumber variety may generally produce 8- to 10-inch fruits, there are always exceptions, so don’t go by size, but rather by appearance. Pick cukes just as soon as they ripen to encourage the plants to keep producing fruit. Store them in the fridge for one to two weeks, or prepare vinegar-based cucumber salads that will keep for up to a week when refrigerated. Canned pickles keep for weeks or months. The skin contains valuable dietary fiber and nutrients, plus it adds a lot of crunch, so leave the skin intact when eating raw or using in recipes for the most dietary benefits.

Cucumbers Companion Plants

All plants do not grow well together. For instance, cucumbers should be planted well away from tomatoes, sage and other aromatic herbs, such as lavender, mint or lemon grass.

On the other hand, vegetables such as radishes, beets and dill are good choices for planting in close proximity to your cucumber plants. Not only do they benefit your cucumbers when it comes to utilizing and providing needed nutrients, many of them will also help deter the most common cucumber pests, such as aphids, cucumber beetles, spider mites and pickle worms. Dill, for instance, will attract lacewings, which in turn will decimate an aphid population in short order. Lacewings will also eat the eggs of the cucumber beetle.

Growing cucumbers with marigold flowersMany flowers, such as nasturtiums and marigolds, are an effective form of pest control, naturally reducing the need to utilize chemical pesticides in your vegetable garden while adding an attractive border or colorful accent. Experts recommend planting the most pungent marigold varieties, such as French or Mexican marigolds.

The healthiest and most pest-free gardens will grow in a naturally beneficial environment. To learn more, you can read our article on Natural Pest Control.

Origin: Africa; Asia; S. America

Description: These annual plants grow as a single, upright stem with ribbon or strap like leaves. The plant usually looks like a mop upside down, but some types of Dracaena grow in small, shrub-like shapes. The glossy leaves come in many colors: medium to dark green, or variegated with white, cream, or red. Dracaena plants grow 1-10 ft. tall (indoors) and up to 20 ft. outdoors in tropical climates. They can be from 1-3 ft. wide.

Propagation: Root cuttings; air layering

Sun/Light Needs: Depends on type and where grown (indoor/outdoor.) Outside, does well in full to partial sun. Indoors, most Dracaena plants do well in bright, indirect light. These annual plants will grow in low light, but the leaves may not be as thick and strong.

USDA Hardiness Zones: 10b-11

Fertilizer Needs: An all-purpose granular (6-6-6) for outdoor plants. For indoor plants, a water soluble fertilizer every few weeks. Check with the nursery where you got the plant; each cultivar may have a different need.

Maintenance: Low. Outdoors, prune (in spring to summer) to make plant grow new shoots. Indoors, repot every three years or so to avoid a root-bound potted plant. When watering indoor plants, allow soil to dry between waterings.

Companion Plants: Cannas or Hibiscus

Problems: The leaves of Corn plants can be toxic to pets and small children. These annual plants can suffer from scale, spider mites, and mealy bugs. Leaf spot can be a concern.

How to Prune Perennial Mums

November 1st, 2013

Pruning_Perennial_MumsHow to prune perennial mums depends on whether they are new or established plants and whether you purchased and planted them in the spring or in the fall.

Spring-planted new mums or already established chrysanthemum plants should be cut back after the first hard freeze in the fall or winter. Use sharp scissors or shears to trim them back to 2 to 4 inches above ground level and then add 4 to 8 inches of mulch, depending upon the severity of your winters, to prevent the plants from heaving out of the ground and the roots from freezing.

If, throughout the winter, your nighttime temperatures stay above 40°F, you probably won't need to mulch, but you may have to stay weather-aware and cover them during any extremely cold, unexpected weather events. If you've mulched, you can remove or pull back the mulch once the nighttime temperatures are consistently above 40°F in early spring.

Newly planted, fall-blooming chrysanthemum plants have not had the time to develop a strong, well-established root system, as they've been devoting most of their energy to blooming. You should NOT cut back any new fall-planted mum plants in the first season. Wait until the following spring when the temperatures start to warm to cut back the foliage. Until then, your plants should either be heavily mulched, or potted and moved to a protected spot, in all but the most southern areas of the U.S. If you opt to pot and move them, do so before the first hard freeze.

If you'd like to prevent your chrysanthemums from blooming in mid- to late summer, preferring to have fall blossoms instead, pinch the new growth back periodically throughout the summer once your plants reach 4 to 5 inches tall, repeating every few weeks until about the middle of July. This will encourage bushiness, as well as a mass of flower buds ready to bloom in September and October. Then, clip the copious amounts of blossoms to make bouquets and live arrangements, which will also encourage extended fall blooming.
