It's been cold all over New Zealand this week; Nelson has had two consecutive overnight temperatures below 0C, which is cold for Nelson. But every year, by June, I don't feel the cold any more and much time is spent on perpetual weeding.
This year I learned about multi-level potting of different bulbs, the idea being the smaller ones on top flower early and medium and larger ones will follow. The top layers have come out, but now I don't know what's going to happen to the violets, (the purple ones may die after this morning's frost), or the subsequent layers on top. I only followed the instructions from a bulb company!
