I understand snowdrops should be planted early, mid-September I am reading, but we are having such a heat wave (relatively) that I’m wondering is it too warm to plant them , or actually any of my spring blooming bulbs?
Thank you for contacting Toronto Master Gardeners.
Ideal planting conditions for fall bulbs are when overnight temperatures fall to lows of 5-10 °C, and the soil is warm enough to be workable. Based on the recommendations of major bulb suppliers, snow drops do not need a different planting schedule than other fall bulbs.
Ideally, bulbs should be planted as soon as received. However, nights in Toronto are still rather warm for planting. So, remove the bulbs from any plastic bags and store on trays covered with damp peat moss or sawdust in a cool, well-ventilated, preferably dark place until overnight temperatures are low enough. Do not store below 4°C.
Follow the bulb supplier’s directions when you plant.
Here are some general bulb planting tips from the Toronto Botanical Garden:
Good luck with your snowdrops.
