When to Trim Bushes

I wanted to know what is the best time of the year to trim bushes, spring or late fall? Why?

ANSWERS

It really depends on the bushes and if they are bushes that bloom from new growth or old growth. Which plant do you wish to trim? We can give you more precise directions on how to trim it if you let us know.

Do any types of flowers grow after cutting?

ANSWERS

Yes, there are several kinds that do. This is a practice called deadheading. You take off the first batch of flowers and the plant will grow a second batch. Here is more information: https://www.gardeningknowhow.com/ornamental/flowers/fgen/deadheading-flowers.htm

Cutting Back Shrubs

When is the best time to cut all of my very large shrubs back all the way low to the ground? They are much too large. I have been living here 19 years and they have never been cut all the way back or down low.

ANSWERS

It really depends on the type of shrub, but a pruning in spring for non flowering shrubs is normally ok. Most shrubs will not tolerate being cut back by more than 1/3. There are only very specific shrubs that respond to rejuvenation pruning like you are talking about. If you let me know what kind of shrubs they are, I can tell you if you can do rejuvenation pruning on them.

Fireblight

I would like to confirm once and for all how much to prune below fireblight infection.   I see 8 to 12 inches, at least 9 inches, etc. I think it’s really supposed to be 12 inches and no less.

ANSWERS

Yes, most resources do specify cutting back branches 8-12 inches from the canker margin, or affected area. However, I recommend 12 inches, as the canker margins are not always well defined and at least this way, you're more likely to get all of the infected area. Always better to be on the safe side.
