May Gardening Checklist: 19 Tips to Keep Your Organic Garden Healthy in May


Welcome to our monthly series what to do in your garden. This month is May and we’ve got a busy month ahead of us. Mother’s Day comes in May and if there’s any moms in your family that are also gardeners, I highly recommend you look at a selection of gloves at groworganic.com. We’ve got waterproof gloves, rose gloves, thorn gloves, lumber cutting gloves, check it out and take care of the mom in your family. I know we spoke about keeping up with the weeding last month, but that’s an every month event. Be sure and check out our video How to Control Weeds Organically, you’ll find a lot of tips to make weeding easy. May is usually warm enough here in Northern California to put out our warm weather transplant starts, Tomatoes, peppers and eggplant. Start by hardening off your plants. What we mean by this is take your seedlings to a protected location outside for one hour for the first day. Do this each day for a week. Add one hour for each day of the process. By the end of the week you’ll be at seven hours and the plants will be ready to be transplanted. While inside the seedling stems haven’t been exposed to winds. Plants, like humans, need to start our workouts and gradually increase the intensity to become strong. Play it safe and keep some Agribon row cover on hand to protect from some surprise May frosts. If your soil is in need of a little boost before you plant your transplants you can apply a little bit of this All-Purpose Vegetable Fertilizer or some of the Chappy’s Soil Inoculant. Get out your soil thermometer and if the soil is warm enough you can direct seed a lot of your seeds. Many seeds like cucumbers, melon and squash need soil temperature about 70 degrees, but all of the important information is on the seed packs or online at groworganic.com. If you haven’t already done so be sure and check all your irrigation. Check the batteries and your timers. Check your drip lines for leaks. Make sure that everything is working perfectly so that when you start your garden it’s ready to be watered. It’s a good time to check for pests like aphids, cabbage worms and use the appropriate sprays or sticky traps or beneficial insects. At groworganic.com we have a Pest Control Solution Chart which is very very helpful on the first page of our pest control category. If you planted onions and garlic last fall now is the time to peel back the mulch and give them their first shot of fertilizer. Look for telltale signs of voles, moles and gophers. And set out some traps if necessary. Check out our How to Control Gophers Organically video for a lot of really good tips. Prune off any spent flowers from your flowering shrubs. This is especially important for lilacs because the new growth is going to come right where the old flower was. May is a time to fertilize your blueberries and other acid loving plants with this Acid Mix. If your spring blooming perennials have stopped blooming in May it’s a great time to divide them. Check out our video on How to Divide Perennials. Take care of the bare spots in any lawn that you might have. Lawn Restore and the Dr. Earth Lawn Fertilizer are great additions as well as reseeding bare patches. This Earthway seeder is a great way to spread it all. Check out our Organic Lawn Care video for lots more tips. Inspect your outdoor furniture for unwanted creatures living underneath and it’s the time where the stinging insects are going to start bothering us. Be sure and have something on hand and handy just in case. Be sure and install some bat houses invite the bats to your property so that they’ll eat thousands of mosquitoes every night. And May is not too late for successional planting of early spring crops such as radishes and greens. Check your roses for disease and give them a dose of fertilizer, Flower and Rose fertilizer works great. If you’ve had grasshopper problems in the past or if your vegetable garden is close by to a grassy pasture you may have grasshopper problems in the future. This is a Nolo Bait which is a suppression for grasshoppers. You can put it on a little bit early in the season, like in May. As with all pesticide products be sure and follow all the directions completely, read the label carefully, and wear your protective gear. And most importantly don’t forget to enjoy your garden in May and grow organic for life!

Great video – we're in Ohio zone 6 (I think lol ) and have had a garden for 4 years (moved to this place 5 yrs ago) – it's not organic but we DO NOT use anything but water, egg shells, epson salt in our garden, put cardboard down then cover with mulch, leaves and/or grass clippings (oh and we do have a composter).
