Sorry you're having trouble with your lettuces. Check whether it is the right variety for the time of year. Unsuitable varieties for the time of year will often stay open and go to seed. Lettuces like cooler conditions generally but there are a number of varieties developed for the hotter months. Warer stress can also cause this even if it was in the punnet before purchase. Trust this helps, sorry I can't help you more.

Why does my lettuce produce new leaves on top but the bottom leaves turn yellow and wilts? Looks like it is growing well, since new leave appear all the time, but the bottom leaves then wilts... What should I do, or what am I doing wrong?

Your lettuce is probably getting too much sun or its too dry... try putting them in a more shady spot and watering plenty?

I have a problem with growing iceberg Lettuce. As soon as it starts making heads it rots within 2 weeks time I have to throw them all away. I have same slugs however I do not think this is the main problem. We have a very high rain falls. Could this cause the lettuce to rot?

Hi I am assisting a community garden project in Grasmere, South of Johannesburg. Please advise if lettuce can be planted in May. Thank you

Hi Imthiaz, just picked up your question today and thought I could provide some clarification, especially as we are in the same area.I Find that lettuce love the cooler months here, and will take some light frost. They tend to "bolt" in the hot summer months and do better in broken shade during this time. If you plant seeds in trays at the beginning of Feb. you can start planting out seedlings in early March and continue through to Oct. / Nov.

You grow different kinds of lettuce in the cooler months to the hotter months.
