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.
