Carrots: first crop basically failed: poor germination and die off, second crop planted earlier than usual did well. Make sure to keep soil moist after sowing.
Celeriac: strong seedlings, plants did well; too close together. If we’re going to continue planting these, maybe we should plant half as many?
Celery: strong seedlings, most plants did well, may have wrapped too early, research blanching and companion plantings. We need to keep an eye on these once they are wrapped and it rains. A couple of them rotted. Needs calcium (eggshells) and boron.
Parsnips: poor germination despite pelleted seed (straw mulch or soil temperature?), those that matured were good, harvested late Late harvest after poor germination reinforced the need for serious thinning, as most of the parsnips harvested were a good size.
