Plants in containers
Wind and intense sunlight will make it necessary to water
your container plants daily except in early spring and fall
when the temperature is cooler. Because the leaves of a mature
plant will cover the soil surface making it difficult for
moisture to reach the roots, you can't always count on rainwater
to provide adequate moisture. It is important to water the
roots by soaking the plants until water drains out of the
container. We often add water-absorbing polymers to the soil
at the time of planting which will help keep the soil moist.
Before you water, check to see if the soil is dry.
You can fertilize annuals biweekly with a water soluble fertilizer.
For perennials, trees and shrubs I prefer time release capsules.
Feed them once at the beginning of the season.
In hopes that you'll be able to enjoy perennials, shrubs
and trees for more than one season we select plants for containers
that are hardy in zones colder than ours (i.e. lower than
zone 5)
Perennials and shrubs planted in the
ground
Newly installed plants should be watered at least twice a
week, more often if it's over 85 degrees and windy. Gentle
soaking for about 30 minutes to an hour, always in the morning,
is more effective that quick frequent waterings because soaking
the ground encourages the plants' roots to establish themselves
deeply into the soil. Avoid watering in the evening, water
can stay on the leaves overnight and encourage disease. To
test for moisture, dig under the mulch and into the soil a
few inches to see if it's dry. Wilting leaves are usually
an indication that your plants need water. We do not recommend
fertilizing in ground plants for the first year. After that
a balanced, granular slow release type is recommended. Deadheading
(removing the spent flower heads) improves the look of perennials
and very often encourages a plant to re-bloom.
Trees
Trees have large roots and will benefit from slow, steady
watering once or twice a week. Place your hose on the root
ball at a slow trickle and leave it in one spot for several
hours. Move it to another spot and repeat. Keep the tree mulched,
but do not mound the mulch around the base of the trunk. It
will take at least 2 years for a tree to become established.
Sod and Grass Seed
Newly installed sod and grass seed should be watered twice
a day: early in the morning and around 5pm in the afternoon.
Avoid walking on sod for the first two weeks. After
sod and/or seed has been established it should receive at
least one inch of water a week, either from rain or your hose.
Wait two weeks before mowing, then mow using the highest blade
position on the mower. Fertilize the following year.
Winter Care
Do not melt ice with rock salt; always use calcium chloride.
Broadleaf and needle evergreens benefit from watering in the
winter. Keep watering until the ground freezes.
