Hunger isn't nice whatever the temperature. Most wild animals that die over the winter do so just as spring is arriving, it's not the cold that gets them so much, as the lack of food. Order or buy seed from seed catalogues and plan what you'll grow from seed this year. I think of this as buying genes for the garden. Perfectly packaged and prepared for growth with all they need to get started.
Seeds are natures own genetic technology.
If you've never grown anything from seed before, it's one of gardening's main wonders, watch out for the article next month. Last chance to plant trees and hedges from bare rooted stock , many nurseries will stop lifting field grown plants this month if they haven't done so already. Use an old pair of tights as a tree tie. They're strong, don't rot, are soft and cheap. Tie around the tree and stake in a figure of 8 so that the tree trunk doesn't rub against the stake.
