Hello everyone,

So I had an interesting situation I wanted to tell you all and ask for your opinion on it. Our Landlord sent people to prune and spray the fruit trees we have in October, and the people with the pruning and spraying company said, "Your landlord sent us to prune the trees, but it is not the right time to do fruit trees." As the gardener in the family I talked to them and we both agreed it was not the right time because we thought frost would damage the trees open wounds from pruning. I called the landlord and explained that it was not the right time to do this. They were understanding and told us to reschedule for the proper time.

This leads to three questions:

First, did I do the right thing putting off the pruning till it was time to do it?

Second, Cherries and Apricots have to be pruned before growth starts in late winter and Plums have to be pruned in summer. Is this information correct?

Third, when do you start spraying Cherries, Apricots, and Plums for diseases and insects? How often do you spray?

I want to have a better yield of fruit next year to make more jam because my family LOVED it.

Any help will be appreciated,

Jared

Hi Jared,

Prune your cherries and apricots right after you harvest their fruit. The rest (plums, peaches, nectarines, apples, walnuts) should be pruned when they are fully dormant (for me, that's about Thanksgiving). If you prune too soon, the trees will put out new growth that will be killed during the first frost. A BIG waste of energy.

Spray on the major holidays (its easier to remember): Sometime between Thanksgiving and Christmas and again on Valentines Day.

Fertilize early spring, late spring and mid-summer.

The easiest way to get a good fruit crop is to prune the trees properly. Do the tree guys know what they are doing?

Hello,

Thanks SO much. I really appreciate the help. I think I will take your advice and try to prune after harvest.

Unless dormant sprays have changed, Fruit trees require three spraying. After leaves fall. When buds start to swell. Then after petal fall.

I live in central valley .
California, threw out the rules for correct pruning time, for fruit trees, a long time ago. From what Ive learned, seen, and read. Prune, right after harvest, is best .

I tip my hat to you.

I have peach trees in NY and I always thought your were supposed to spray 3 times, all in spring/early summer?
as soon as buds emerge, then ~30-45 days and a 3rd/last go at the same interval. I've never heard of spraying after harvest/fall?

I have no idea where I got that information from, so it could be complete nonsense/old wives tale. Maybe its just location differences- we get some pretty hard freezes over the winter here- that might have something to do with it.

In the warm climates the bugs don't die over winter.

I don't know what the temperature ranges are in Nampa these days. According to the 1990 Hardiness Zone Map, Jared is in zone 6a. With global warming, he could easily live in Zone 8 by now. That was a spraying scedule for zone 8. Smiling

We used a dormant spray consisting of dormant oil, liquid sulfur and something like malathion. You had to suit up and wear an air mask to use the stuff.

Last year, Jared was dealing with a variety of insect issues and bacterial issures. A spray of something deadly (like malathion or sevin) at the popcorn stage would also benefit.

But I was thinking a dormant spray with sulfur would cure a lot of his past problems. All that deadly stuff is pretty frowned on these days. But the sulfur was pretty deadly for me (allergy). Smiling

All of these spray times are designed to avoid the beneficial insects and just do in the overwintering baddies.

Here in Reno, I don't spray for anything.
