How do you know when it’s time to start planting? Our weather has been more spring-like here in Michigan than wintery and if you are anything like me you have your seeds ready to go.
Is it too early though? A major deciding factor is what you want to plant. It is by far too early for summer crops like tomatoes, peppers, and eggplants, which shouldn’t hit the ground until mid- to late-May. But for the spring crops*...it depends.
For those marvelous spring crops that we all love to plant as soon as the ground thaws and the sun kisses the air? The deciding factor is the soil-- the soil's moisture and the soil's temperature.
First, grab a handful of soil and squeeze it into a ball. If the soil becomes tight and holds its shape too well, then it's too wet to plant. Rototilling soil this wet or even walking on your crop rows at this point will compact things unnecessarily. However, if your handful of soil becomes a light ball that breaks apart easily, your soil's passed the first test of spring.
The next consideration is your soil temperature. Cool weather vegetables need the soil to be at least 35 degrees for your seeds to germinate. An inexpensive addition to your gardening toolbox is a soil thermometer. A good strategy when you are unsure if the temperatures will remain warm enough is to plant only a section of your crops, then wait a week and plant more. This way, if temps drop too far, your entire crop won't be lost. Staggering your sowing also spreads out your harvest a bit-- an added bonus.
Now before you put your seeds in the ground don’t forget to prepare your soil. Ready to purchase your Living Worm Compost? Click here. It's never too early or too cold to stock up on compost. Not sure how much you need? Email me at Corey@goodsweetearth.com and I'd be happy to help.
(*For the record, these are really the only things you should be putting in the ground in the early spring: spring cabbage, garlic-cloves, kale, onions, peas, radishes, shallots, spinach and turnips. Those are your spring crops that are able to handle a little extra cold.)
