Hey everyone! I'm a long-time reader but first-time poster here. I've got a raised bed that's now in its fifth year, but I've noticed a tree nearby has grown quite a bit taller, meaning my garden is currently only receiving about 4 hours of sunlight each day. I know that as the season progresses, I'll get more sun, but I'm wondering: is it okay to start my tomatoes now, or should I hold off until I can provide them around 6 hours of direct sunlight? Eventually, the whole bed should get over 8 hours. For reference, I'm in zone 10b, and my indeterminate tomatoes from last year are still producing like champs even in full sun!

It really depends on your location. For example, I’m in Chicago and I started my tomatoes on March 6. I kept them in a bright attic, and they germinated in just 5 days! Now they've been moved outside under a hoop, but we just had a snowstorm, so I'm holding my breath for them. But if you have warmth consistent in your zone, starting with 4 hours could work.

That’s awesome to hear! I'm in San Diego, and I've got loads of sprouts from last year's fallen tomatoes. I just transplant them wherever I want, and they usually thrive!
