I Have An Oleander Tree (I Keep It Protected In Winter) And For The 2nd Summer Have Lots And Lots Of Flower Buds But Very Few Open

Question

. What can I do next year?

Answer 1

There is an abundant number of ways to develop flower buds that still do not open; see which one applies in this case: lack of water or insufficient water; too much water; too much nitrogen from lawn fertilizers (use high phosphorus fertilizers); too little direct sunlight (aim for much more than 6 hours); competition for nutrients from other plants/some trees/weeds/grass/etc.; pruning when the plant is developing flower buds; pest infestation (mealybugs, scale, aphids, etc.);
