No success with peatfree growbags.

The heat even if well watered can affect growth for some plants. I grow cot and come again leaves in the next raised bed to last year. They have all bolted

Peat is lovely to grow things in, but it really needs to stay where it is.
It's like anything in the garden - weeds, aphids, fungus - it may be more arduous to grow things more-or-less organically, but unless we do, we absolutely can't condemn farmers who use these chemicals & take up hedges etc.

Interesting. Thankyou folks
I have had success in the past with a couple of growbags, but they were probably peaty ones. The compost was much softer and easy to water.
I do grow them outside as well but I have problems with slugs and snails.
I can keep a closer eye on them in the greenhouse.
Everything has gone to seed this year or shriveled. I'm in Scotland but even here we've not had nearly enough rain.

I’ve found a supplier locally for peat compost. Peat free is rubbish in my opinion.

Our grow bags are doing very well but the tomatoes do need watering daily. I wouldn’t grow lettuce in them anyway…..much prefer cut and come again salad leaves in wide shallow pots about 10cm deep to a full head lettuce. Although my cucumber plants has died but I did get one cumber off it and I’ve harvested the seeds…….pleased with that considering I paid £4 for FOUR seeds - special variety - won’t be F1 but worth a try.

DH bought RHS peat free growbags and these growbag pots. He used peat free compost in the pots and also mixed in some farmyard manure. He planted his tomatoes rather deeper than he usually does. They are growing well, he waters them daily.
