Have you been bitten by the gardening bug and are now itching to plant? The cool, wet weather we’ve been enjoying has had gardeners impatiently waiting for the soil to warm and the skies to stop peppering us with hail so our plants can finally go outside.
Now that the National Weather Service is saying we’re in for warming up and drying out, be patient for a few more days to let the soil temperatures rise. Wet soil warms more slowly, because the sun’s energy goes into drying it out; once that’s accomplished the ground will be ideal for us to pop peppers, eggplant and tomato seedlings in.
Soil temperatures play a big role in when to plant our garden vegetables. For the peppers, tomatoes and eggplant, warmth needs to be 60 degrees or more, with the ideal being above 65 degrees. Planted too soon, the seedlings will sit and snit, refusing to grow until temperatures are more to their liking.
Planting seeds in cool soil is tricky as well because many won’t germinate and instead rot. Beans, pumpkins, and squash should not go in until the soil is above 60 degrees. The warming soil should happen fairly soon, since the ground has a chance to dry out in the next few days.
What haven’t had a problem with the weather are weeds, which with all the moisture, sprouted with abandon. They’re growing with vigor, and if not brought under control, they’ll crowd out your beds and be difficult to remove.
Take this time to focus your energy on pulling weeds from the rain-softened soil. They’ll come out fairly easily and you’ll feel the sense of satisfaction from clearing the weeds out. If you’re especially frustrated by not planting, whack the weeds with your hoe a bit to wrench them from the ground.
Most of these early-season weeds are good fodder for the compost pile since they haven’t had tome to produce seed heads. Those which have can still be composted; just snip off the seeds before tossing the plant on the pile.
