Blacbird, I do try to research my plants, but there is sometimes so much information out there that it becomes a lack of information, you know? Funny that you mention lilacs, though, as I happen to have a lilac bush in one corner that doesn't seem too happy. Maybe some lime will perk it up again!
I also have a HUGE Meyer lemon tree and a plum tree (the fruit are the big red kind) as well... do you know if they prefer lime or eggshells or coffee grounds or what? I don't do much other than water them, as they both seem well-established and provide plenty of fruit regardless of how I treat them. But I would like to make sure they're getting whatever nutrients they need, and so far I haven't been able to find much other than the basic information to plant them... not necessary since both are at least two or three decades old, at least!
