|It's time to ditch my windowsill grown lettuces|
It's too late to save my pictured 'Amaze' lettuces. A quick nibble on a leaf showed they're too bitter for eating. As these are windowsill grown, I'm not going to save their seed - NAH has been most tolerant of my growing activities, but I think seeding lettuces in the bedroom might be beyond his limit!
Outside I'm keeping my non-bolted lettuces well picked and well watered and I've moved the potted ones to a much shadier part of the garden*. These measures should help prevent my remaining lettuces from doing what comes naturally. As soon as they start growing upwards then I'll have to decide which are going straight to the compost bin and if any are worth saving for seed. So far, Black Seeded Simpson, Freckles, Marveille de Quatre Saisons and the iceberg varieties are resisting the urge to bolt the most.
It's really too hot at the moment to sow their replacements (lettuce doesn't germinate well if soil temperatures are above 25oC), but I'm going to have a go at sowing some later in the day and keeping the seed trays in the coolest, shadiest part of the garden to let the seeds take advantage of the cooler nights. If this doesn't work, then I'll simply wait until next month to get my next batch of lettuces going. NB it's also time to sow a variety of non-lettuce leaves ready for late summer/autumn picking.
Have you found any particular lettuce varieties which are less reluctant to bolt? It would be great to compile a list of them for future reference :)
