    Yes, but you need to wait until after all danger of frost has passed. Pruning before this time will lead to infection. When the weather is predicted to stay above freezing, then you may prune them then.

    Q.post-bloom plumeria care

    My approximately seven-year-old plumeria finally bloomed last summer, to my extreme delight. The plant has three stalks, and only one bore flowers. The leaves of this stalk are yellowing, while the leaves on the other two look normal. This stalk still has the four-inch-long auxiliary stalk that bore the flowers still at its end. Should this be removed, and if so how? And why are only the leaves from this single stalk yellowing?

    Yes, you may want to remove the stalk, cutting it back to the base of the plant. Also, check for signs of rot or pests that may be contributing to this issue. Does the stalk feel soft? Is it oozing? These are signs of stem rot. Treating with a fungicide, like neem oil, and keeping the soil dry should help with this. Holes in the stem could indicate a pest problem. Removing the affected stalk and treating with neem oil will help.

    This can happen when the fertilizer has too much nitrogen. Try getting a 10-30-10 to get it too bloom. They will also want it to be warm and humid to help this.

    Yes, you will just have to leave it to nature. I don't think it will be a problem, and it will continue on normally when the weather stays warm. Here is an article for more information on the plant: https://www.gardeningknowhow.com/ornamental/flowers/plumeria/growing-plumeria.htm

    I would wait as long as possible to cut them unless is starts to spread. Then you will want to do so. There is not a lot to be done here except wait for it to show signs of life again.

    The sticky substance is likely honeydew, which is the secretion of pests.

    Several pests are common to Plumeria including Spider Mites, Aphids, Mealybug, Scale and Whitefly.

    Neem Oil is a good treatment for all of these sucking insects.

    Here are some links with more information.
