Spring is here and I know you are anxious to be in the garden. As soon as the temperatures begin to climb it is really tempting to get seeds in the ground. Before you take that step, however, I encourage you to make sure the ground is ready for your seeds. Of course, you will loosen the soil and add compost and, if necessary, organic fertilizers, but did you take the temperature of the soil?
Seeds are naturally programmed to germinate and grow within a certain range of temperatures. Within that range they will grow faster or slower, depending on their comfort zone. It has been my experience that just because it is the right time to plant on the calendar, it may not be the right time to plant according to the soil. The temperature of the soil is more important than the date on the calendar. When I was a market gardener I would be anxious to get sugar snap peas in the ground in early March. I would put in another planting two weeks later.
