I always grow Romaine-types as they (especially the reds) have more heat resistance and also have higher nutrition than any of the lettuces.
You ca take off leaves around the edges and it won’t hurt the plants at all.
Due to our ridiculous early heat, all of mine have bolted (gone to seed) so I am culling what I can (it gets bitter when it colts) and replanting bush beans in their place.
In fact, that’s on this morning’s To Do List, while it’s still cool. Going up to 82 today, then hoter every day this week.
Still only that 1/2” of rain, so I’ll be watering everything again this week.
Which Bean?
