Soil Temperature and Seed Germination

Why do we plant when we do? There are lots of reasons. As the bible says in Ecclesiastes, “there is a time to every purpose under heaven.” Some plants and seeds are very forgiving about the planting time. Others are not. Soil temperature is one important factor. Seed germination and soil temperature are very interrelated. Some plants like most of the crucifers require a fairly cool temperature for optimum germination. Other’s like beans require a high temperature.

Another factor in the time for planting is day length. Some plants set seed when the day gets to a certain length. If seeds are the desired crop this is great. If leaves or roots are the desired crop, it is not so great. Tomatoes will grow really well in short days. They just don’t produce flowers or tomatoes.

Another factor is the time to maturity of the plant. If a plant takes a long time to mature the growing season in a particular area may not be long enough unless the plant is started earlier in a greenhouse. Of course the gardener’s patience may be the reason for planting slow maturing plants inside. Who can wait for that first tomato?
