Jim, Totally Tomatoes lists the Bela Rosa as a determinant plant. From what you've written it sounds like they're a bit of a semi-determinate plant. For my home garden I've been looking at indeterminate plants in hopes they'll make all through the summer. Do you find that the determinate tomatoes actually have a longer harvest period or do they mostly ripen all at once? I was thinking that with a determinate plant I'd find myself suddenly wrapped up in ripe tomatoes.
