When picking Victoria plums, I noticed very small clear modules on the surface in a bunch. They do pick off easily and don’t seem to leave any clues of how they got there. I could send photos if needed.

They have peach borers, likely. They can affect any stone fruit. This article will explain more and help:

Plums – This Year the Fruit Rotted on the Tree. Why?

I had a good crop of Victoria plums but before ripening the fruit started to decay.

It sounds like the tree may have a fungus. Some fungus that get into the fruit can be treated, while others cannot. Your best bet would be to treat the tree with a fungicide. It may stop the fungus from spreading. Even if it does not, you can stop the fungus from returning next year by making sure that all of the leaves in the fall are properly disposed of.

Miniature Victoria Plum

I have a plum tree with loads of fruit on it, but I think that I have an infection on the tree as the leaves are curling up and going black. Please advise on how to treat it.

This is sooty mold. It happens when the plant gets a pest infestation, likely aphids. I would recommend using neem oil, as this will get rid of the sooty mold fungus and kill the pests. Here is some articles that will help you:

Plum Tree Not Fruiting

My Victoria plum has loads of leaves but no fruit. It has fruited well previously, but as it is planted in the lawn, I wonder if lawn feed has affected it. Should I clear the grass from around it, and what feed should I use to put this right?

This article can help with reasons for non-fruiting: https://www.gardeningknowhow.com/edible/fruits/plum/plum-trees-not-fruiting.htm

I think it may definitely be the fertilizer from your lawn, which normally contains lots of nitrogen - this would result in lots of lush foliage growth with little to no blooms or fruit. You can usually offset the nitrogen by adding a phosphorus rich fertilizer, or bone meal, to the soil around your tree.

Problem With Victoria Plum Tree

Our plum tree is in a large pot and in a sheltered position. We give it plenty of water and it is producing plenty of fruit about 1. 5 times thumbnail size, but we have recently noticed that some of the leaves have developed brown streaks. Is this a problem and if so what can we do about it ?

If the streaking is nearest the leaf veins, it might be a virus. I would suggest taking a sample to your local agricultural extension office for identification and recommendations for treatment.

Why Are My Plums Rotting Before They Ripen?

We have a Victoria plum tree that we inherited on our allotment about 4 years ago. It was only small then so we don’t know exactly how old it is. We have had the usual good year bad year as far as volume of fruit goes, but never this problem. A lot of the fruits (and there are loads this year) are turning purple/black and shrivelling up before they ripen. Is it because there are too many on the tree for it to cope with?

It sounds like brown rot. This article should help: https://www.gardeningknowhow.com/edible/fruits/plum/plum-tree-diseases.htm

Victoria Plum Tree

I have a minature Victoria Plum tree that I planted last year. It was very healthy with some fruit but I have noticed that the plums are shrivelling up and not growing. They were all doing really well until the last few days. Is there something I can do to stop all the fruit being destroyed? Many thanks
