Let’s get your garden ready for a beautiful and productive season!
1. Assess & Clean Up Your Garden
Before planting, it’s essential to clear out winter debris and assess garden conditions.
✔ Remove fallen leaves, branches, and dead plants – This prevents mold & pests.
✔ Check for frost damage – Cut back any dead or damaged plant parts.
✔ Clean garden tools & sharpen pruners – Helps prevent disease spread.
✔ Refresh garden beds – Rake soil, break up clumps, and remove weeds.
💡 Tip: Apply a layer of compost now to enrich the soil for spring planting!
2. Test & Prepare the Soil
After a long winter, soil needs testing & enrichment to support new plants.
✔ Test soil pH & nutrient levels – Use a home test kit for accuracy.
✔ Loosen compacted soil – Use a garden fork to aerate & improve drainage.
✔ Add organic compost or manure – Provides natural nutrients for strong growth.
✔ Apply mulch – Helps retain moisture & prevents early weeds.
💡 Tip: If soil is too wet, wait a few days before digging—working wet soil causes compaction.
3. Prune Trees, Shrubs, & Perennials
March is the best time for pruning before new growth starts.
✔ Trim dead or damaged branches from trees & shrubs.
✔ Cut back late-blooming perennials like lavender & ornamental grasses.
✔ Shape fruit trees to encourage strong fruiting branches.
✔ Avoid pruning early-blooming shrubs (like lilacs) until after they flower.
💡 Tip: Use sharp, sterilized pruning shears to prevent plant diseases!
4. Start Seeds Indoors
Some plants need a head start indoors before transplanting outside in spring.
Best Seeds to Start Indoors in March:
🌿 Vegetables: Tomatoes, peppers, eggplants, broccoli, cauliflower.
🌸 Flowers: Marigolds, petunias, zinnias, snapdragons.
🌿 Herbs: Basil, parsley, oregano, thyme.
🔹 How to Start Seeds Indoors:
✔ Use seed trays or small pots with drainage holes.
✔ Fill with light, nutrient-rich seed-starting mix.
✔ Keep soil moist but not soggy.
✔ Place in a warm, sunny window or use grow lights.
💡 Tip: Once seedlings grow 2-3 sets of true leaves, start hardening them off by gradually exposing them to outdoor conditions.
5. Direct-Sow Cool-Weather Crops Outside
Certain vegetables thrive in cooler temperatures and can be planted outdoors in March.
Best Vegetables to Plant Outdoors in March:
🥕 Carrots
🧅 Onions
🥬 Lettuce & Spinach
🌿 Peas
🥦 Broccoli
🌾 Radishes
💡 Tip: Use row covers or cloches to protect young plants from late frosts!
6. Divide & Transplant Perennials
March is a great time to divide crowded perennials to encourage healthier growth.
✔ Best perennials to divide now: Hostas, daylilies, asters, ornamental grasses.
✔ Dig up clumps carefully & separate into smaller sections.
✔ Replant in fresh, compost-enriched soil.
💡 Tip: Water newly transplanted divisions well to reduce shock.
7. Get Rid of Garden Pests Before They Multiply
Spring pests emerge early—act now to prevent infestations later!
✔ Remove dead leaves & plant debris – Many pests hibernate in garden litter.
✔ Check for slugs & snails – Use crushed eggshells or diatomaceous earth to deter them.
✔ Introduce beneficial insects like ladybugs & praying mantises.
✔ Spray neem oil on plants to prevent aphids & spider mites.
💡 Tip: Companion planting with marigolds & basil helps naturally repel pests!
8. Prepare Your Lawn for Spring Growth
A healthy lawn starts in early spring—March is the time for reviving the grass!
✔ Rake up winter debris & dethatch the lawn.
✔ Aerate compacted areas to allow water & nutrients to reach roots.
✔ Overseed bare patches with fresh grass seed.
✔ Apply organic fertilizer or compost for healthy growth.
💡 Tip: Wait until the soil temperature is above 55°F (12°C) before applying fertilizer.
9. Plan & Install Garden Structures
March is the best time to build or set up:
✔ Raised garden beds – Great for small spaces & better drainage.
✔ Trellises & archways – Support for climbing roses, peas, beans.
✔ Birdhouses & bee hotels – Encourage pollinators & beneficial birds.
✔ Rain barrels – Collect water for eco-friendly irrigation.
💡 Tip: Paint or stain wooden structures now before plants start growing around them!
10. Start a Compost System (If You Haven’t Yet!)
Spring is a great time to start composting to create nutrient-rich soil for your garden.
✔ What to Compost: Fruit & veggie scraps, coffee grounds, eggshells, leaves.
✔ What to Avoid: Meat, dairy, oily foods, pet waste.
✔ Turn the compost pile weekly to speed up decomposition.
💡 Tip: A compost bin with aeration holes helps break down waste faster!
