It's a ways off I know, but my polyhouse raised bed of 6 cherry and 2 regular tomato plants are going great, absolutely chock with fruit, as are the 2 cucumber plants. Anyway it's got me thinking about next year and realizing that my raised bed is the only place that I could ever have for tomato. So my question to anyone who can put me right: is it ok to dig out the old plants when the time comes, maybe add some manure, then have a go with a bit of confidence again next year. I am a total beginner, so I have to learn from the likes of y'all good folks.
