Water

– When watering during periods of windy dry conditions, it’s important to water slowly and deeply. Be sure to watch the spray of sprinklers and adjust accordingly with the wind.

– Water all plants well after planting and regularly through the first year. Plants will begin to use more water as they grow and bloom. Outdoor potted plants dry out quickly as do hanging baskets and small annuals. Check new plants daily for water needs, many will need water every day.

– Mulch around trees and flowerbeds to conserve moisture.

– Make arrangements for someone to water if leaving for more than 2 days (especially new plants).

– Watch your perennials. Check soil moisture before watering. Many plants can die from over watering. Use a moisture meter when in doubt.
