adjusting gritty mix
Help me with this one gang..... I'm potting a kiwi vine (A. Kolomikta) in gritty mix. Kiwi likes slightly acidic to neutral soil, is a shallow rooted woody deciduous vine, and needs to be moist all the time but root rot is it's #1 enemy. Also, once established it's a heavy nitrogen feeder.
The pot is 20" wide by about 18" deep? Holds about 10 gallons of soil. What would be your starting guess as to the mix and fertilizer to use? I was thinking about 1.5turface, 0.5 granite,1 pine bark. I will probably miss some watering days... and use just a hose (plain water) other days. I'm a busy person.
The container is technically a self watering 1 got from gardeners supply last year. I holds up to 4 gallons in the resevoir.
