Crocus year 2022
Janis Ruksans:
Yesterday took off winter cover from greenhouse beds. Today the first job was cleaning of plants from old flowers - some melantherus and laevigatus were covered when they still were in bloom. Fusarium nivale and penicillium on old flowers is very dangerous as can go down to corms. A lot of crocuses showed flower buds. Here few pictures - all in closed buds due lacking of sun. Outside all the day was snowing.

Janis, what has been the lowest temperatures in your greenhouses and does the soil ever totally freeze?

This winter we had for 1 night minus 23 C outside. Below cover temperature didn't fall below -2 at top of pots and +2 C at bottom. Soil in pots were frozen for some time, that it was impossible to pick out labels. Then I covered with 3 layers of night-frost protection film (white, thickest variant - 50g/sq.m, thinner is not ussable). The price here for 100 m long, 1.6 m wide roll was ~70,- Eu.
