Q. My plums ( not sure what type I have) when growing often secrete a thick sap from the fruit, it does not seem to affect them but

was wondering if this is normal, as my other plum trees do not do this.

This can have many causes. In many cases this is no cause for alarm. If this is excessive, or prevents fruit from ripening then it could be an issue that needs treating. This article will help: https://www.gardeningknowhow.com/edible/fruits/plum/plum-tree-is-bleeding-sap.htm

Q. My Santa Rosa plum has some disease that leaves a black covering on the leaves, fruit and stems, and covers everything under the t

ree. There is also sap oozing from the tree. What is this and how can I treat it and save this mature plum tree? All the fruit has now dropped, so is pruning appropriate now?

Q. How to deal with brown rot?

Have brown rot on a plum tree. I am going to cut back all branches in the next day or two. Is there a spray I can use on it to prevent it happening again next year, and will it matter how far I cut it back?

Q. Plum tree problem

We have a Victoria plum tree, some three years old, last year it produced a good crop of good healthy plums, this year it has produced a much larger crop, but a lot of the fruits have a sort of resin on them and this causes the fruit to rot. Is this what is known as “brown rot” ?? See pictures, I removing them as and hen detected, any help and advice would be a great help.

This appears to be the early stages of Plum Brown Rot. The disease can be controlled at this stage, but not likely cured, for the remainder of the tree's life. Luckily, with proper care each year, your tree can be symptom free or close to it.

Q. plum tree leaves are cracking and drying up

Red plum tree looks sick. Its leaves are drying up and have cracks on them. I have given Miracle Grow but I can’t get things to clear up. It gets enough water. It is only 2 yrs old.

I'm thinking it isn't getting enough water. Plums are very thirsty and should be watered 2 to 3 times a week 6 inches down through fall. Other environmental and cultural problems are discussed below. Consult your local extension agent for the proper timing and use of chemical fertilizers.
