Sunburn on my tomatoes!
Here’s a tip for all you tomato growers out there: when you harden off your tomato plants, don’t put them in bright sunlight – at least, not for the first few days anyway. The poor things get sunburn (or leaf burn if you want to use the technical term)! This is particularly true of my Brandywine tomatoes; the other two varieties I’m growing (Gardener’s Delight and Gardener’s Pearl) don’t seem to be as bothered by the sun. Apparently (see here), the thing to do is put your tomato plants in a shady spot for the first few days of hardening off, and then they’ll be OK. And don’t get water on the leaves, either.
