Hi there,

I have a lemon tree living outside in a terra cotta pot. It's been having some problems lately and while lifting up the pot to see if roots are coming out, I noticed a little pile of sandy-looking dirt-like material under the drainage hole (which is covered with window screen). Is something living/eating inside my pot? Could that be the source of my tree's unhappiness? We do have lots of ants around and I'm wondering if they have anything to do with this? Any wisdom/suggestions/advice would be much appreciated!

Thanks...
