Looking at the tomato packets they say harvest from June. I've always found I'm really harvesting in Sept but that might be because I don't care for them as much as they need?? Anyone found they can crop tomatoes as early as june?

Okaaaaaaayyyy looked at the packets and found these. Anyone advise if they're any good to grow in practice? Also, some packets are a tad old so germination may not be 100% but it doesn't stop me from trying (hence I still have them, lol)

I think they're giving away veg plants to schools - you tell them how much space you have, and they send you plants to fit in the space. Might help with having things ready to pick fast enough for the kids? If you get enough plants for half of your space & the kids sow some stuff too?
Just a thought...
