Summer lettuce — Extension agent Rebecca McMahon and I have received questions this week about heat-resistant or summer lettuce. In the master gardeners' demonstration garden, Rebecca says, "we plant Black Seeded Simpson leaf lettuce (and we try other varieties that claim to be heat- and bolt-resistant). We try to plant a row every two weeks, because it grows quickly in the summer. It is also very important to keep the soil moist until the seed comes up. We harvest the lettuce when it is 'baby leaf' size, because it will start to get bitter in the heat after that, then pull it and replant it."
Rose tip _ Winifred Brim of Wichita called to remind me of a tip that Frank Good, late garden writer for The Eagle, used to give for roses: Once a month gently dig a tablespoon of Epsom salts around each of your roses and water it in. It makes for thicker stems and more of them, Winifred says. She does it starting in May or June and going through August. She used to mix in the Epsom salts with her fertilizer and dig it and water it in together. She also recommends using old nail polish to seal the ends of rose canes after you've pruned them.
I soak myself in Epsom salts after a particularly grueling bout of gardening.
Planting calendar _ Plant sweet potato slips (plants), and seed directly in the garden winter squash and pumpkins.
