Hey all,

Been thinking of creating a bottle-drip irrigation system for my 7-year-old 7.5ft outdoor potted lime tree. I've read how sensitive these trees are to over/underwatering as well as root-rot, so I was hoping to get your opinions?

1) Would a bottle-drip system be good for a lime tree or not? If you think it's a good idea:

2) how large of a receptacle should I be using?

3) how often should I fill the bottle?

I'm located in Israel, in the equivalent hardiness zone of 9b/10a (wasn't colder than 35f this winter, average for the 3 months of winter was 45), with the average summer temps at 95f and humid. Currently been giving it 1.5 litres every 5 days but I have a deep suspicion I'm underwatering it. Was giving it 2.5 litres, but then had a bunch of fungus gnats develop so I reduced it. (now they only show up the day I water the tree, and no other times).
