I build simple row covers over my raised beds to keep the soil and plants a little warmer. It will keep them snug enough that they can put on so healthy growth, but it won’t overheat them like row covers would in summertime. I have found that I can even direct sow crops in my raised beds about a month earlier than normal.

Laying out greenhouse plastic over our raised beds to make row covers
My system for constructing row covers is really easy and inexpensive. In the summertime, I replace the greenhouse plastic with bird netting to keep feathered friends and the occasional cat-looking-for-a-litterbox out of the raised beds.

The row covers over my winter kale has already given this crop a boost. There is lots of new, leafy growth on these plants after just a couple weeks under the covers. My other spring bed of lettuces and broccoli is off to a slow start, so I just finished covering them tonight.

The drawback to using row covers is that you’ll need to water the plants, since rainwater won’t be able to get to them. We have so much rain at this time of year that our rain barrels will easily be enough water to give the vegetables a long drink. I’ll try to post an update in a couple weeks about how much new growth is on the spring row covered crops.

How is your spring garden coming along? Are you in sunny San Diego where summertime is a year round treasure? Or in snowy Montana where there are still inches of snow on the ground? I’d love to hear about your spring plans in the comments below.
Is your spring kale left over from the winter? Do you just cut back the plants or? I’m wondering because we eat kale constantly and I would love to grow it as many months out of the year as possible… (I live in Tucson, AZ… “Mild winter” is an understatement.
Thank you for any help! 
Amber, I plant a winter crop in fall and a summer crop in spring. That said, last year my kale was over a yr old when I pulled it out – it was just too tall at that point. I suggest you plan on two rounds of planting a yr, letting them overlap a bit to keep a constant crop available. That way the older plant can feed you guys while the newly planted one has time to get established.
