I will have to try it. I made a garlic "tea" to deal with a pest problem and I didn't have a spray bottle at the time so I used a bottle with a hole in the cap. The water dripped freely at first and then it seemed to have trouble. I suppose it could have something to do with the liquid (I added pepper later.)
I just found some terra cotta pots at great prices. I plan on transplanting my lavender in the next few days or so if time permits. If I can work it in, I can try using the bottle watering system then.
