Overwintering pots of bulbs in a glasshouse
I have lost so many bulbs planted in borders in the last few years …. squirrels? Mice? It doesn’t seem to matter how deep I plant them. So this year I have planted miniature tulips and allium Purple Sensation in pots, which I intend to place in a cold plant house over Winter. I am anxious not to over or under water them and would appreciate advice on frequency of watering. Water when planted then check once a month to make sure there is some moisture? There will also be pots of agapanthus and alstromeria overwintering there. Would the same guidelines apply?
