Amendments for Non-SWC Container Tomatoes
I had some extra plants this year and I wanted to try them out in containers since I had reasonable success with one in a container last season. Despite not being in an SWC, the plants I tried last season did really well with minimal maintenance and watering like once a week, maybe, since we got so much rain and had cooler than usual temps.
Well, this season, so far, is completely opposite. Last year was much cooler temps and rain every 2-3 days, this year is 2 weeks without significant rain and temps up in the 85-95 range. I need to soak my container plants at least every 3 days and I'm beginning to feel that the frequent waterings may be leaching out a lot of nutrients. The plants in the containers Isis Candy, Jaune Flamme, and Black Cherry and all are already over 6 feet tall and loaded with fruit; They're doing great, and I want to keep it that way.
I was thinking that with the additional watering / fertilizing, it may be advisable to add some epsom salts and maybe some lime - does anyone more familiar with container growing have any experience with this? If so, are there any recommendations on amounts or rates of application? I'd estimate the containers are about 18 gallons each hold about 2.5-3 cu ft. potting mix.
Thanks in advance.
