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.
2 Comments on “June Garden Guide”
As soon as my milkweed leafs back out after recovering from being stripped by the monarch caterpillars, the aphids show up. They don’t seem to have a negative effect on the caterpillars. Is there any reason to worry about the aphids? I have also noticed the ladybugs show up as well. I’m assuming this is a good thing, but just wondering if I should worry about all those aphids.
Thank you! And thank you for these monthly garden guides!
Aphids will slow down the growth of new foliage, but the plant will still grow anyway. Hummingbirds and ladybugs will enjoy eating aphids. But if you want the fastest growth, you can knock the aphids off with a sharp spray of water and they will not be able to climb back up.
