I always love how the oils darken the bark and make them shiny.

Its almost christmas and my apples still have 40-60% leaves . Southern IL 6b. Cherry and peach almost 100%bare

The last leaves that are still on are most likely the last push of growth that the trees put on. You can still spray the bark areas and then spray again late winter/early spring.

Hi Gary, so our peach tree is showing signs of scabs, hole shot disease and insects causing cat-facing. We noticed that the peaches look very healthy until about two weeks before they are ready to be picked. So, they seem to be most vulnerable as they ripen. This one peach tree is bearing about as many as 1000 peaches. I collected about 500 so far, and the rest look really health but I am afraid they will start getting damaged two weeks from now. Is it okay to spay the fruits themselves this late in the game? And if yes, what could be safe to spray directly on the fruit to reduce their damage at this stage?

It’s early March in Michigan but 40 to 70° weather doesn’t look like it’s on the horizon. What should I do?

@GrowingwithStarkBros 5 ай бұрын

As long as it is above freezing for the day and when it's applied, it is ok to spray.

Is neem oil okay to substitute for the horticulture oil?

@GrowingwithStarkBros 5 ай бұрын

Neem Oil is typically used when it is warmer out to help with insect control, they have similar functions, but Horticulture oil is generally used more specifically as a dormant oil spray.

I’m in 9B, northern San Diego Co. My Elberta miniature peach has leaf curl right now (August 2022). I transplanted it when I moved here in 2020 and it has not bore any fruit from the stress it is under. I did spray it this summer with horticultural oil once because the lemon tree next to it had mealy bug infestation so I sprayed all the trees. They look healthier but the peach has leaf curl. Should I spray it now or wait until around mid-November and again in February? Do I cut any effected branches off now? Thank you.

@GrowingwithStarkBros 2 жыл бұрын

Hi Lisa. Do not spray or prune now. The only effective control for peach leaf curl is to spray when fully dormant with liquid copper fungicide in late fall after leaf drop and again in late winter before bud swell. During dormancy, the liquid copper can be combined with horticultural oil for a broad spectrum, preventative and curative treatment. This will address diseases, insects and mites. Use the highest rates on product labels during dormant applications. This is safe and will be the most effective. Pruning can be done as needed, after the tree is dormant and has been sprayed twice. -Gary

Is it to late to spray the trees if the buds are swollen? Or should I wait till the leaves drop in the fall. The trees were just planted 2 weeks ago and I'm in a zone 7b.

@GrowingwithStarkBros 2 жыл бұрын

The tree needs to be fully dormant. If there is any sign of bud swell, it could damage sensitive tissue. Rather than potentially doing more harm than good, I would wait. Prepare and plan for a dormant spray application after leaf drop in the fall. -Gary

@WiredPirate1 2 жыл бұрын

Same situation as you. Planted a couple weeks ago in 7B. Trees started waking up almost immediately. I should have sprayed when I planted. Guess I’ll be waiting til fall

Thank you so much for this video. I live in a zone where it's very rare for temps to be in the 40-70 degree range between Valentine's and March 1. It's usually colder here. Do I spray anyway, as long as the other conditions are suitable? I'm growing apple trees for the first time (columnar apples I got from Stark Bros) and I've grown really fond of these little guys. Unfortunately, I noticed that they're coming down with some kind of disease and I've been trying to figure out how to save them. Thanks again!!

@GrowingwithStarkBros 8 ай бұрын

Hey there! Great question. The important factors here are “Full dormancy” and “Temperatures 40 to 70 degrees F”. The calendar is not definitive. Mid- February to early March is just a typical window for the majority of growers. If you’re in a colder zone, the trees will break dormancy later, meaning you can spray later. Again, as long as the tree is still fully dormant with no bud swell and temps are adequate, it’s safe to spray. This is the first pro-active action to combat pests and diseases for the next growing season but more action may be needed when the tree starts growing in the Spring. -Gary

@@GrowingwithStarkBros Thank you so much for responding and for your advice! We had a really odd summer season this year (affected by the Canadian wildfire smoke and whole range of other oddities) and trees in my area seem to be going into dormancy later than usual. My baby apples haven't dropped many of their leaves yet, for example, so I don't think full dormancy has been reached. I'm new to this and need all the help I can get. I'll watch out for the conditions you've described. Thanks again!

What is the trunk wrap you are using and why?

@GrowingwithStarkBros 2 жыл бұрын

The trunk wrap is a Stark tree guard to prevent rodent damage potentially girdling the tree, protection from sunscald and premature sap flow. It is white to reflect sunlight to help regulate the trunk temperature and prevent excessive temperature fluctuation. - Gary

How is it around honeybees

@GrowingwithStarkBros 2 жыл бұрын

Excellent question. The horticultural oil is safe and the liquid copper has no insecticidal properties, however, to be safe this dormant spray combination should be applied when bees are not actively foraging. Choose a time, like early morning, when bees are not active. Once the spray has dried, there is no potential harm to honeybees. - Gary
