Is drip watering practical for container trees?
I have 3 ultra dwarf fruit trees, a fig, apple and peach. They are growing in 24" containers. Because they have ample drainage, I soak them fairly thoroughly about twice a week. It is now in the 90's here. They all have developed dry and curling leaves, and the fig's leaves have mostly fallen off. I'm thinking about putting drippers on them and dripping daily. My question is, will a dripper simply wet a narrow swath of soil down through the planter, leaving the rest dry, or will it spread sufficiently out from the dripper to wet most of the soil? Also, how does fertilizing work with a dripper? If I spread the fertilizer around away from the trunk, will a dripper sufficiently wet it to carry it to the roots?
In short, is dripping practical for container trees?
