I've planted a Bearss seedless semi dwarf lime tree in a container. The leaves are curling and falling off. I've noticed webs on it. I'm also wondering if I'm watering it right. I would appreciate any help you can give. Lorna

Webbing on the leaf stems, along with yellowing and dropping leaves is a sign of spider mites. These tiny little pests like dry, dusty conditions so to discourage them, just hose your tree off periodically. They will take a hike if things are too moist. Frequency of watering really depends upon the weather and how much new growth your tree is putting out. I would allow the top inch of soil to dry, then water thoroughly - until water flows freely from the drainage holes. Once in a while you'll want to either immerse the container in a larger container of water, or flood the soil by drenching it two or three times in succession. The idea is to completely saturate the soil to force out any air pockets that might have developed within the root mass. This happens quite often with containerized plants so flooding the soil will help eliminate the air pockets. As for feeding, since your tree is in a container it will be safest to feed lightly but more frequently. I'd use a water soluable fertilizer such as Shultz's or Miracle-Gro, diluted to half-strength and applied every 2-3 weeks during the growing season. this method of feeding supplies a constant source of nutrients without the concern of over-feeding containerized plants.

Hope this information is helpful!
