Hey there, fabulous gardeners of the Mid-Ohio Valley! March is when things finally start waking up around here—like your garden's had its coffee and is ready to party. We've pulled the best tips from our favorite garden guides, grouped by week for easy peeking. A little humor, a lot of know-how, and zero frostbite required. Grab your coffee (or hot cocoa if it's still chilly), and let's get growing!
Week 10 (March 1–7, 2026)
Harvest overwintered vegetables if they're still toughing it out—those little survivors are like garden superheroes.
Order herb seeds now while the good stuff lasts (basil, thyme, and friends will thank you).
Apply lime and fertilizer according to your soil test—think of it as a spa day for your dirt.
Order fruit trees while choices are fresh and plentiful.
Build a high tunnel if you're feeling ambitious (extra season = extra veggies, win-win).
Seed head lettuce (indoors)—quick and crisp for those early salads.
Turn compost—free gold for your beds, no store run needed.
Build a low tunnel or cold frame for tender babies.
Seed leeks, cauliflower, and celery (indoors)—slow starters that pay off big.
Clean dust from houseplants with a damp cloth—your green roommates will breathe easier.
Week 11 (March 8–14, 2026)
Sunday, March 8 - Daylight Saving Time Begins
Seed carrots, leafy salad greens, and radishes in high tunnel—fresh crunch coming soon!
Start a kitchen herb garden in pots—snip fresh parsley while dinner cooks.
Prune grapes now for sweeter bunches later (they're basically getting a stylish haircut).
Seed broccoli and cabbage (indoors) plus collards and kale—cool-weather champs ready to shine.
Seed peas (outdoors) south of U.S. Rt. 60—they don't mind a little chill.
Plant Irish potatoes in high tunnel for early spuds that make you smile.
Week 12 (March 15–21, 2026)
Tuesday, March 17 - St. Patrick’s Day
Friday, March 20 - Spring Equinox
Prune blueberries, raspberries, blackberries, elderberries—shape 'em up for a berry explosion this summer.
Seed carrots, onions, and greens in cold frame or low tunnel for sneaky early harvests.
Apply dormant oil spray to fruit trees (bye-bye overwintering pests).
Prune deciduous trees and shrubs while they're still napping—way easier now.
Mow asparagus ferns to clear the runway for new spears.
Propagate grapes and blueberries from hardwood cuttings—free plants? Yes, please!
Week 13 (March 22–28, 2026)
Propagate elderberries from cuttings and order cold-hardy fig plants—expand that berry/fruit patch without the big spend.
Presprout seed potatoes for a faster jump on the season.
Build a raised bed garden if you're ready (easier on the back, better drainage—smart move).
Order wildflower seeds to bring in the pollinators and pretty pops of color.
Sow sweet pea flower seeds for outdoor planting in mid-April—they'll climb and charm like crazy.
Seed celery transplants if you haven't already.
Prune figs to keep 'em neat and productive.
Week 14 (March 29–31, 2026 – wrapping into April)
Finish any lingering pruning or propagation.
Resist uncovering daffodils and tulips too early—let that mulch protect those shoots from cold winds.
Spread dark plastic mulch over garden spots to warm the soil faster (earlier planting = happier you).
Keep milk jugs handy to shield early pansies and crocuses from surprise freezes.
Start annual flower seeds indoors: aster, larkspur, alyssum, snapdragons, petunias (and zinnias if your summer is short).
Start veggie seeds indoors: Brussels sprouts, broccoli, cabbage, cauliflower, peppers, eggplants, tomatoes, lettuce—use sterile seed-starting mix and grow lights.
Re-pot houseplants, plant deciduous trees/shrubs as soon as ground thaws, and prune fruit trees before buds swell.
Remove suckers from fruit trees, rake lawn debris, and give everything a good once-over.
