I suggest you transplant to the next size pot, and douse it the day you leave...over water it.

I hate it when I have to leave my garden, unattended or to the attention of others...even one watering. LOL I am so friggin paranoid.

I, unlike you, have a neighbor who is also legal and can drop in and water for me.

But, I am considering making a drip system for those times I am away for more than overnight. Shouldn't be that hard to do.
