My shrub has leaves that are curling, whats causing it?
If you have many leaves over the entire plant that are curling, there are two common reasons: 1) Wet soil whick can slow the transfer of nutrients and cause a curling effect. This should clear up as soon as the soil dries. 2) A chemical called 2-4,D may have been sprayed and drifted on to the plant. This chemical is for killing dandelions and other broadleaf weeds (if you have sprayed a weed- killer, look on the label for the chemical name in tiny letters). But it is notorious for traveling several houses away to wreak havoc on other broadleaf plants. Unfortunately, those leaves will stay curled for the remainder of this growing season.
