Cold weather and a blanket of fresh snow might not seem like the right time to don some gardening gloves and grab your pruning shears, but for certain types of hydrangea bushes, now is the time to prune them!
As spring moves forward, you can prune not only hydrangea now but also certain types of other shrubs. If you鈥檙e interested in learning more about all types of pruning, Charlie Nardozzi is holding a
various trees and shrubs, Charlie will be at the Gardener's Supply retail store in Williston on Saturday, March 30th at 10 a.m.
As for pruning hydrangeas, the key is knowing which type of flowering bush you have. That's because the type dictates how and when to prune!
Hydrangea shrubs that bloom in late spring and early summer are ones like the classic mop-head or lacecap type, blue hydrangea, oak leaf hydrangea, climbing hydrangea and mountain hydrangea. These bloom on what is known as "old wood," referring to branches that overwinter. These types should be pruned right after the hydrangea is done blooming in early summer.
For other kinds of hydrangea that bloom in late summer or early fall, like the paniculata or panicle hydrangea, these bloom on new wood 鈥� meaning the new growth that comes out of the stems and terminates in a flower.
For these varieties, prune them now and trim them back to a structure so that they have more new growth. Remove any competing branches and cut them back to a height that you like. You can prune pretty severely; the plant will bounce back and still flower.
One little caveat is the blue hydrangeas like the "Endless Summer" type: They have what is called a 鈥渞eblooming habit." If you are growing this type, the time to prune those is just like the other blue hydrangea: prune them after they're done blooming in the early summer.
A listeners asks if charcoal is good for garden soil
Q: A friend is very excited about using charcoal to add to his raised beds as a method for providing and storing nutrients in the soil. If you recommend it, is it considered organic? - Ed, in Morrisville
A: Charcoal can be used as a soil amendment, as long as it's not regular charcoal that you would get at a store for grilling and things like that.
Instead, is an activated charcoal which is used agriculturally. Biochar is made of organic materials that have been burnt at very low oxygen levels so they become charcoal. It is also effective in retaining water and nutrients. It can be used for phytoremediation, meaning taking out contaminants in the soil.
Another way to help your soil retain water and nutrients without charcoal is to use excess wood and build a That uses wood in a mounded shape which you then cover with soil and plant vegetables and herbs into and on top of it. The same thing happens here where you鈥檙e locking up carbon in the soil and reducing the amount of effects on global warming.
Give either method a try in your garden and let us know how it goes!
