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.

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.
I have a mature Japanese blueberry tree that was hit hard by the freeze, but it’s now making a comeback. There is growth at the very top and in the middle, right where the old dead branches start. The new branches are about 8 inches long now. Can I still prune the old dead branches, or should I wait until the fall to prune them? I don’t want to stress out the tree. And what kind of fertilizer can I use for this tree?
Medina grow and green is a safe and gentle organic fertilizer for aiding your trees recovery. You can prune out deadwood now, no problem for the tree.
Should you use neem oil and hastagro at the same time?
You could feed the soil with Hastagro and use Neem oil on the foliage at the same time, but you wouldn’t want to spary both on the foliage at the same time. Always best to use these early morning or late evening – don’t apply during the heat of the day.
James, is it possible to grow a Japanese ed Maple tree in Rockport?
I would not recommend it, but if you want to try anyway, sandy soil, a bit of shade, and protection from harsh winds would be things in your favor.
Hi James,
I have a new fan flower plant in a hanging basket and it has gorgeous pink flowers. I’m have trouble controlling the water level. I put it in the shade, I put it in the sun, I have moved it three times. I thought I was over watering it and it dried out in two days. What do you suggest?
Thanks,
Jeanette
Hi Jeanette – shade in the Summer is good, and try to keep it on the dry side generally. And use a moisture meter to let you know for sure when it needs water.
Thank you so much Jesse
