If you touch the soil and it notes wet and caked, you need to aerate the soil by stirring it and applying sandy-textured soil to the mix.
If the leaves turn yellow adopting a wrinkled texture and the whole plant seems to decay and lose strength, most likely it needs more water. When one of your plants has suffered a severe drought, don't overwater it. Instead, soak the entire planter in water for a few minutes, then let the soil drain off the excess.
