March Gardening Checklist: 9 Tips to Prepare Your Organic Garden for a Successful Growing Season

We’re here in Northern California in USDA zone 8. Here’s what we do in the veggie garden in March. Depending on your zone you may be able to get started on preparing your beds. you can also get them ready for cold tolerant plants like radish, kale, and overwintering greens. As soon as the soil is workable you can test your soil. You have a few options for testing your soil. You can buy a kit and test the soil yourself, or you can collect your soil and send it to us by mail and we will analyze it and send you the results within a couple of weeks. You can also test just the pH of your soil with a variety of products found on our website and fertilize according to the results. Work an inch or so of compost into your garden as well. if you planted a nitrogen-fixing cover crop, turn it under a month before you plant so it has time to break down and fix the nitrogen in the soil. This could be in March. Turn it under before it goes to seed when it is beginning to bloom. To learn more about cover crops see our video how to grow a cover crop. And make sure to get all those small weeds before they get established. If they are already established watch our how to control weeds video which offers tips on preventing weed germination, weed flaming and suggest some great weeding tools. March is also a great time to put up your sticky traps and start monitoring for pests. Look closely at your established gardens for aphids, snails, and slugs who all love the cool damp weather of spring. Check out these great products to prevent and control these pests such as Sluggo, Slug Saloon and Slug Shield and the safer insecticidal soap. It’s also time to put out gopher and other pesky animal traps. They will be looking for places to build their nests and you don’t want them doing that near the garden. It could also be time to prevent mosquito and fly infestations before the height of the season is upon you. Check out our biological controls targeting mosquitoes and our beneficial fly parasites on our website. Prevention and early control will pay off later in the season. Watch our relevant pest control videos for more information. March is not too early to begin planting in most zones. This is a great time to plant potatoes and also cold hardy crops such as beets and kale. If you live in a mild winter climate you can also plant greens and other semi hardy plants now. Refer to our garden calculator which includes first and last frost dates and suggests what to plant and when. Be sure and buy your soil thermometer if you don’t have one. Keep some frost blankets or Agribon or row cover on hand for when a spring cold front moves through. These are very effective and easy to install on most any plant. Don’t forget to enjoy your garden in march and stay tuned for what to do in your veggie garden in April, and Grow Organic For Life!


  1. Yep! I am in Texas and have had pumpkins growing from seed for a while now. A freeze killed off most of them but I still have 8 left. I am a little glad the freeze got most as I was worried about the vines causing problems. I had about 40 seeds that sprouted. Also my mulberry trees are getting the leaves back and fast. Now just to try to be patient for the little bit of fruit I can get before the birds. laughs I don't fight pests at all – especially snails and slugs – since fireflies need them to reproduce. I also love our snails because they have neat shells… I feel horrible if I step on one though. – Heidi

  2. Last year we started a 30 inch high raised bed CORE garden. This year I
    was surprised how compacted it got and the amount of topping off I had
    to do but the results of the garden was incredible. Well worth the work
    that went into it. The videos I did on it do not hold a candle to yours
    but you can view them to know what I am referring to. In any case, we
    have taken some tips from you that we have used in our garden. Thank you
    … and keep up the great work.
