I don't know about the gardening zone but I live in North ArkansasQ.Red Tip shrub/trees
I have numerous Red Tip shrub/trees. Most are at least 20 feet tall. Last year they started losing their leaves and I sprayed them with a rose solution. This year, however, the leaves are falling worse and I have a large oak tree by the house that English Ivy has taken over. The leaves are starting to yellow and fall off of it also. Can you tell me what you think may be going on and what fungicide I should be using?

Certified ExpertA.I would evaluate your red tips for Entomosporium Leaf Spot, which would cause the leaf drop you are experiencing. For information on photonia leaf spot and a course of treatment, please visit the following link:
https://www.gardeningknowhow.com/ornamental/shrubs/photinia/photinia-leaf-spot.htmAs for the oak tree, it is very possible that the English ivy is the cause of its problems. English ivy can damage trees and competes with it for water, nutrients, and light. It can also transmit bacterial leaf scorch, which causes leaves to be tinged with a yellow or reddish-brown color and to drop prematurely.

MarylandQ.cut back my red tipped photinia
I cut back my red tipped photinia and now leaves have holes and some are curling. Bushes had black spot and thought cutting way back would help but now I have other symptoms. Some of the new leaves are curling and some have holes or looks like something is eating them. Any suggestions?

Certified ExpertA.Without a photograph I can not be 100% certain, but the black spot on your red tip could have been caused by a fungus (such as photinia leaf spot). Black spots on leaves could also be sooty mold, which is secreted by aphids, scale or mealybugs, to name a few. These pests, in addition to thrips, can also cause leaf curl and can be difficult to spot - you may need a magnifying glass to see them. I have included links below which discuss these pests and provide a course of treatment.

One of our red robin photinias has suddenly died. We did not notice any leaf spot, and others near to it appear to be ok.

June 14, 2015A.A fungus is the most common plant disease effecting the photinia.
Clean up any leaf remains from the ground and dispose of.
Inspect the plants and you may want to treat with a fungicide.

July 24, 2015Q.red tipped photinia
I need to completely remove some red tipped photinia bushes (mature - 12' tall). I am wondering what type of root system they have. Will there be a main taproot or various smaller roots? Thank you.
- Answered by

July 26, 2015A.From what I understand, these shrubs have a fairly heavy, or extensive, root system. However, I believe as long as you are able to get out the majority of the root ball, you should be ok.

9Q.Can red tip photinia be planted in august?
Need to establish visual hedge quickly, don’t want to wait until spring. Can Red Tip Photinia be planted in Texas in August?
- Answered by
Downtoearthdigs on
July 27, 2015A.You can plant them now but you will need to be very diligent on watering and care.
Watering once a day for at least the first 2 weeks. You may need to even provide a screening for the plants if the temperatures are very warm.https://www.gardeningknowhow.com/ornamental/shrubs/photinia/growing-red-tip-photinia.htm

Certified ExpertA.Unfortunately, this is why fall planting is usually better in warmer climates. Once established, the shrub should be fine. However, all you can do now is what you already are, keep it watered. It may also help to trim it back some.

August 5, 2015Q.Leaf spot on Red Tip Photinia
I have leaf spot on my very long Red Tip Photinia hedge. I can't get rid of it without spraying every two weeks. Spraying is not a good option because of windy conditions and very close neighbors. Is there any other way to control this?

Certified ExpertA.Unfortunately, fungicide sprays are the norm, though the can be applied on days when wind is not a factor, and the usually cause little harm. Cleanup of plant debris is also important.
