Will bulbs survive winter in pots?
Keep Bulbs Cold But Not TOO Cold This means you’ll need to store your potted bulbs through the winter in a place that stays colder than 48° F most of the time but that doesn’t get as severely cold as it is outside. Plant your bulbs too deep and flowers will bloom late or not at all, plus you’re likely to get more foliage at the expense of the flowers. If planted too shallow, new growth will become exposed too soon, leaving it more vulnerable to damage by cold temperatures.The soil nearer the surface will be warmer than the soil deeper down, so the higher you plant your bulbs, the more the chance of them being in warmer soil and therefore of getting cooked .
What do you put on top of bulbs in pots?
Cover the bulbs Add more compost to cover the bulbs completely, then firm down gently. Then position your next layer of bulbs, in a similar way to the first, and cover with more compost. Position your bulbs nose up and cover with a thick layer of compost, then water well. You can add a layer of gravel to the top to help prevent weeds or plant a late-flowering cyclamen for some autumn and winter colour. Bulbs don’t like waterlogged soil, but you don’t want your pots to dry out completely.
