We have at last finished planting out our broccoli – over two weeks late. The delays were due to wet soil preventing cultivation. Happily the plants were thriving in their 4″ deep wood flats. But it was tough to get them to thrive when transplanted that big. The weather was hot on most of those days, so we had to water a lot, even thought he soil was still saturated from the heavy rains.
Here you can see how we mulch our spring broccoli and cabbage: we make temporary raised beds, 4′ wide with one foot paths. then we unroll big round bales of spoiled hay over the beds and the paths too. They are just the right width for the bales. After that we make two rows of “nests” in each bed, using a measuring stick to get the right spacing. We use our hands to tease the hay apart down to soil level. Then we transplant, water in and close the hay over the soil around the stem of the plant. Then we cover with rowcover to protect from cold nights, bugs and stiff breezes. We use sticks to hold the rowcover down, rolling the edges under rather than over, which helps them stay in place and not tangle with hoses or feet.
A week after transplanting, we’ll go through and replace any casualties with slightly younger plants. We’ll also put one plant of alyssum every 6ft down the center of each bed. After we remove the rowcover, this little flowering plant will attract beneficial insects like Braconid wasps, aphid parasites, and syrphid flies. These will deal with aphids and cabbage caterpillars. The paper wasps also carry off the cabbage caterpillars, so we rarely have serious caterpillar trouble.
Completing the broccoli planting means we now have 3 of our 10 row-crop plots planted out. Another one will be cover crops, so we have 6 left to go. Next up will be the Roma paste tomatoes and peppers, on biodegradable plastic. I need to sort out the drip tape for that this week.
In the hoophouse we are making the transition from winter and spring crops to early summer crops. We have planted tomatoes, peppers and summer squash in the middles of the beds (gherkins to come soon), and we are hurrying up the harvesting of the winter crops which are competing for space and sunlight. We prefer to let the winter crops continue as late as possible, for maximum harvests. Soon we won’t need the hoophouse lettuce or greens as the outdoor senposai is ready to start harvesting and the lettuce heads are not far behind.
We’ve moved a lot more flats out of the greenhouse to the coldfarmes to harden off for two weeks before we plant them out in the garden. Not everything goes to the coldframes – we keep the melons and celery inside so they don’t get too chilled, and the eggplant so they don’t encounter fleabeetles. the greenhouse work is starting to taper off for the season. One of the biggest occupiers of space are the flats of sweet potatoes – you can see the first two in the foreground of this picture. they are limp because they have only just been set in the flats. We’ll plant them out about May 10. You can read more about our method of growing sweet potato slips here and here. We’re well on track to have enough by the time it’s warm enough to plant out.
The weather here in central Virginia has been teasing us. It was hot, then cold again. We thought we were done with frosts, then we had some cold forecasts. We covered the strawberries for two nights to protect the flowers, and built height-extenders on the walls of the cold frames with plastic crates, so we could put the lids on without squashing the very tall plants we had in there. Then we got nights of 36F, 36F, 34F, 33F. We had covered the strawberries for the 36F nights, but not the 34F or the 33F, as we followed the forecasts too gullibly! Later today I’ll go to see if the strawberry flowers have black centers – the sure sign of a frost hitting the blossoms.
We always like to think we are done with frosts once we pass April 20, but the truth is our average last frost date for the past ten years is April 30, and the range has been 4/14 to 5/14, with a mean of 5/3.

We recently had a damaging frost on strawberry blossoms after an overnight forecast of 45 F. We’ve long known that anything under 42 or so results in frost (on a clear night) in our valley, but 45 pushed the limits of our expectations. Someday we’ll stick temperature loggers out there to document the actual surface temperature on clear spring and fall nights.
Yes, we had a lucky escape on our 33F night – no black centers to the strawberry flowers. When I say we follow the forecasts, I really mean we subtract 5 degrees from the local forecast as we nearly always get colder temperatures where our farm is. You were unlucky this time – you subtracted your usual 10 degrees, seemed safe, but still got damaged blossoms.
Incidentally I notice I claimed we make 4″ raised beds for broccoli. I really meant 4′ wide beds. Maybe they are about 4″ high, and no-one thought anything odd. . .
