Taking Care of Your Landscape

Landscaping is an investment that adds value to your home. We would like to help you take care of this investment with some helpful instructions.

Watering: Please Don't Tease Your Plants!
DO NOT depend on rainfall to provide an adequate amount of moisture to your newly planted tree or shrub. With quick summer showers, the moisture may evaporate from the soil surface and not penetrate the root zone.

Before the ground freezes in the late fall, give the plants a thorough soaking, especially those that retain their leaves during the winter months.

Watering: New Trees and Shrubs
Water deeper and less frequently. For most soils, you should be able to apply 10 to 30 gallons of water once a week, depending on plant/root ball size. It is always good to apply the water slowly enough that the soil will absorb it and have as little run off as possible. For this reason soil basins and mulch are an important part of the irrigation procedure.

Once established (after a full growing season), trees and shrubs should require only supplemental watering during extended periods of hot, dry weather. Droughty summer conditions adversely affect flowerbuds for the following year as much as extremely cold winter weather.

Watering Your Ground Cover
Water ground covers thoroughly immediately after planting, and continue frequent watering until the plants are established. Water the beds deeply. Shallow watering encourages shallow root growth that is easily damaged during dry periods. After the plants are established, water them as necessary. Wilting is usually an early signal that plants need watering.

Be alert for wilting if your soil is well-drained, or during dry periods. Water ground covers in the morning or early afternoon. If they are watered late in the day, the foliage is likely to remain wet into the evening, when temperatures usually drop. Cool temperatures and wet foliage provide ideal growth conditions for certain diseases. Newly planted beds can be watered by drip irrigation or by "soaker" hoses laid near the individual plant rows. Be sure to allow adequate time for deep watering. After the beds are covered with foliage, use either portable or permanent sprinklers. Water all parts of the bed slowly and uniformly.

Watering New Perennials
Few perennials prefer a soggy or dry location. Perennials generally need an inch of water per week during the growing season. More may be required during bloom or during the hot summer months. Supplemental watering should occur during the morning hours.

Avoid watering of foliage or flowers; diseases are more likely to infect plants. Careful observation of the plant can provide clues to water needs. Thick, succulent perennials such as sedums and stonecrops need less moisture than big leafed plants. Hairy plants or waxy leafed plants require less water than smooth leafed ones.

Mulching
Most plants will benefit from an organic mulch covering the soil surface around them. A good organic mulch, such as hardwood bark mulch, will conserve moisture, help maintain a more even soil temperature, inhibit weed growth, and prevent soil compaction and erosion from rain and irrigation. Applying mulch 2 to 3 inches deep surrounding, but not resting against, the trunk will give you a more vigorous plant. Last, but not least, mulch will help prevent damage by a mower or other lawn equipment.

Mulch, being a natural product, does decompose over time. You will probably find it necessary to add to your mulch, especially the first few years.

Weed Control
Frequent, shallow cultivation and the use of mulch is the first line of defense against annual weeds. As beds start to fill in and shade the soil, annual weeds become less of a problem.

There are, however, times when the use of herbicides may be suggested, such as if the planting bed has a perennial weed problem. If chemical control is used, always read and follow label directions.

After Planting Care and Manicuring
Many perennials and annuals need little additional care. Their flowers fall cleanly off the plant and don't have to be manually removed. Others will need to have faded flowers removed. This process is known as deadheading and is done to keep the plants attractive, from going to seed, and to prevent disease. It also helps to increase flower production. Deadheading can be done with pruning shears or by simply pinching off the old flowers.
