When to Plant Carrots in Massachusetts

Carrots are a cool weather veggie that thrive when planted in the early spring or late summer seasons in Massachusetts. Their delicious crunchy roots and nutrient-dense composition make them a worthwhile crop for any backyard garden.

Determining the right planting times will ensure your carrots grow to their full potential.

This guide will breakdown the ideal sowing windows and step-by-step process for growing hearty carrot crops in the Bay State.

Optimal Planting Periods for Carrots in Massachusetts

There are two primary seasons suitable for planting baby carrots in Massachusetts – early spring and late summer. Here’s a breakdown:

1. Early Spring (March-April): As soon as the soil can be worked, usually around Mid-March through early April, it’s time to direct sow carrot seeds. The soil temperature should be at least 40°F. Cool nights and mild days provide ideal growing conditions.
2. Late Summer (Late July-August): For a fall harvest, plant another carrot crop 6-8 weeks before the first expected fall frost. This allows carrots ample time to reach maturity before temperatures drop.

Avoid planting during the hot summer months of June-July when the soil is warm. Carrots prefer cooler temps for germination and prefer under 70°F soil. Hot weather causes them to bolt, producing woody inedible roots. Stick to the shoulder seasons for your best chance of success.

Step-by-Step Process for Planting Carrot Seeds

Use this step-by-step process for successfully sowing carrot seeds and harvesting a bountiful crop:

Step 1: Prepare the Soil: Loosen soil to a depth of 8-10 inches by double digging or tilling. Incorporate 2-3 inches of compost or other organic matter. Rake the soil smooth.

Step 2: Plant the Seeds: Space carrot seeds 1/2 inch apart in rows 12-18 inches apart. Press each seed 1/4 inch into the soil. Cover lightly with 1/4 inch of loose soil.

Step 3: Water Gently: Keep the soil continuously moist but not soaked until germination, about 10-14 days. Carrot seeds need moisture to swell before sprouting.

Step 4: Thin Once Germinated: Thin seedlings to 2 inches apart once they emerge. Snip extras at soil level for a neat row.

Step 5: Weed Management: Hand pull weeds regularly, being careful not to disturb carrots. Mulch after thinning to suppress weeds.

Step 6: Water Deeply: Provide 1-2 inches of water per week, either through rain or irrigation. Water at the soil surface, not foliage to prevent disease.

Step 7: Fertilize at 4-6 Weeks: Side dress with compost, fish emulsion or other organic fertilizer to boost growth.

Step 8: Harvest from Late Summer-Fall: Begin harvesting baby carrots in late summer when they reach desired size. Larger roots will be ready by early-mid fall before hard frosts arrive.

Post-Planting Care Tips for Carrots

Once sowing is complete, maintain your carrot patch with these best practices:

• Pull emerging weeds frequently when carrots are small to avoid competition. Mulch to smother later-emerging weeds.
• Water deeply and infrequently to encourage long taproots rather than lots of top growth. About 1-2″ per week total.
• Side dress with compost or organic fertilizer at 4-6 weeks after emergence to boost root size.
• Use floating row cover fabric or mesh to keep out carrot rust flies and other pests until harvest.
• Thin baby carrots to 2″ apart to allow plenty of space to grow into full size without touching.
• Leave 18-24″ between rows to allow for harvest, weeding and air circulation to avoid disease.
