Bougainvillea needs time to recover from transplanting

Q. I planted a bougainvillea in with my morning glories in hope that eventually it would take over. It has been in the ground for about two years. It looks good and healthy, but it has only grown about 6 inches. What's going on? - Jack

A. Your morning glories may not have anything to do with your bougainvillea's slow start. Bougainvilleas take several years to establish their root systems, particularly if their roots were disturbed when planted. For this reason, they sometimes don't survive replanting. It is possible that your bougainvillea's root system is just getting established, and it will eventually take off and need very little care.



Q. I have a friend who swears that earthworm castings will kill white flies. Is this true, or is it just another myth perpetuated by the environmentalists? - George

A. Come on now, George, do I detect a note of dislike for those who "Love the earth for all it's worth?" No, I am not downplaying your question; it is very legitimate. As far as I know, there is no scientific evidence that this is true, but there is a wealth of anecdotal evidence. I have heard it many times from those who have tried it. My belief on the subject is that worm castings are one of the very best things that you can give your plants to maintain health and vigorous growth. Since white flies usually attack stressed plants, they are probably just passing by the healthy ones and taking up residence on a more vulnerable specimen.
