Santa Rosa Japanese Plum Tree

About two weeks ago, I planted a Santa Rosa Japanese plum tree in my backyard. I am concerned because the leaves look droopy/wilted. I have been watering it every day and don’t know if I have perhaps over watered or under watered it (the soil feels moist but the leaves look and feel dry). I also noticed that some of the leaves have small tiny holes on them and don’t know if it may be a disease that is causing the droopiness (I tried not watering it for two days and it looks like it got worse). I live in the high desert area of southern California, but the weather so far has been very cool, windy and even cloudy. I know that these trees grow fine here, as have heard of them and I was told by the nursery that they only bring plants that can.

It sounds like it is in transplant shock. This article will help:

It is also possible that there are air pockets in the soil that are affecting the roots. I would step firmly on the soil around the tree to help collapse any air pockets. Flood the area with water to help fill them in. Up its watering as well. It may also have a fungus disease, so I would treat the plant with a fungicide.

Plum Tree

Its a Santa Rosa plum. Have it planted in my backyard 2 years now. Some branches have no leaves, the one that has leaves looks wilted and the tips are brown color. I water, give it food. Gets full sun. What else can I do? Pls. help! Live in Arizona.

I would try increasing water to the tree and treating it with a fungicide. Both too little water or a fungus can cause the issues.

When and How to Prune Plum Tree

I live in Sacramento, CA and have a wonderful old Santa Rosa (I think) plum tree. Can you please give me advice about when and how to prune?

ANSWERS

You should prune a plum tree when the buds are breaking. If you prune the tree prior to bud break you will cause the tree to come out of dormancy to soon. A Japanese plum should be pruned in an upside down umbrella shape with three to four main limbs. A prune plum can be pruned leaving several scaffold limbs in a Christmas tree shape. Longer limbs at the bottom opposite of each other at different heights.

Dwarf Santa Rosa Plum Help

We planted a Dwarf Santa Rosa plum this past late spring/early summer (southern CA). The leaves are turning brown and crisp at the edges and are slightly curled. We water it pretty consistently. Any ideas?

You may be watering consistently, but it still may not be enough for a tree in its first year. I would recommend increasing water to the tree. Make sure that you are watering deeply so that the water is getting all the way down into the roots.

Santa Rosa Ultra Dwarf

Have a Santa Rosa ultra dwarf. Blooming for the 2nd time this year in mid July. Am in zone 10. Is this normal? Tree planted end of last summer.

You are not alone, I found reports of gardeners in your growing zone with reports of similar activity among the fruit trees.

The low number of chill days this past winter and the record setting drought are the environmental issues that most reports are listing as to why the trees are showing 2nd blooms and crops.
Fruit may be small and even inedible.

Pick the fruit as it ripens even if it is not edible. Don't leave fruit on the tree.

Santa Rosa Plum Tree

I just noticed the leaves on my plum tree are beginning to turn brown. Really bad on the west side. I check it all the time and have never noticed anything but today I noticed a big problem. I did some further investigation and found some kind of burrowing bug in a branch. I removed that branch but couldn’t find any more. Should I remove the unripened fruit to reduce stress on the tree? Any suggestions on what could be causing the problem and a possible solution?

Thanks for your help
