Quick Answer
The top 5 vegetables to plant Memorial Day weekend across MA — Plymouth County, Suffolk, Middlesex, Norfolk, Worcester — ranked by yield per square foot and reliability: tomato, pepper, cucumber, basil, bush bean. All five thrive when soil is reliably 65 degrees, frost is a month past, and nights stay above 50. A typical 4x8 raised bed comfortably holds 4 tomato plants, 6 peppers, 2 cucumber vines, 6 basil plants, and a 2-foot strip of bush beans — feeding a family of four through October.
Why Memorial Day Is the Right Window
Across MA, Memorial Day weekend (May 24–26 in 2025) is the consensus warm-season vegetable planting window. Soil at 4 inches sits at 65–70 degrees, frost risk is fully past, and warm-season crops can root in before June heat. Plant earlier and crops sulk in cold soil; plant later and you lose 2–3 weeks of harvest.
For region-specific timing and disease pressure, the UMass Extension Vegetable Program maintains the most authoritative MA-specific calendar.
1. Tomato
Plant: 1 to 2 transplants per 4 sq ft, cage or stake at planting, full sun. Harvest: 60 to 80 days from transplant. Why it tops the list: Highest perceived value, longest harvest, most varieties. Indeterminate (Better Boy, Sungold, Cherokee Purple) bears continuously through hard frost; determinate (Roma, Celebrity) gives one big crop. Soil: Browse the raised garden bed materials collection for bulk Garden Soil Mix.
2. Pepper
Plant: 4 to 6 transplants per 4x4 bed, full sun, mulch with straw to keep roots cool. Harvest: 70 to 90 days for green; 95+ days for color-ripe. Why: Heavy yield, easy care, multiple uses (sweet, hot, mild). Bell peppers struggle in MA short seasons; choose smaller-fruited types (Lipstick, Carmen, Jimmy Nardello) for better yield. Soil: 50/50 Garden Soil Mix + Compost. The Cambridge raised-bed math Q&A covers the soil-volume thinking.
3. Cucumber
Plant: 2 to 3 vines per 4 sq ft, trellis at planting (don't retrofit), water deeply twice weekly. Harvest: 50 to 70 days from seed or transplant. Why: Fast, prolific, and trellised cucumbers save bed space. Pickling cukes (National Pickling, H-19 Little Leaf) for jars; slicing cukes (Marketmore 76, Diva) for sandwiches. Trellis: A simple 4-foot trellis at planting beats any retrofit cage. The Suffolk County tomato cage hacks cover trellis hacks that work for cucumbers too.
4. Basil
Plant: 4 to 6 plants per 4 sq ft, pinch weekly, harvest from top down. Harvest: Continuous from June 15 through hard frost. Why: Pairs with tomato (in the bed and on the plate), pollinator-friendly when flowers run, freezes well for winter pesto. Care: Pinch the top 1 inch every week — promotes branching, delays flowering, doubles total leaf yield.
5. Bush Bean
Plant: Direct-sow 1 inch deep, 4 inches apart, full sun, succession-plant every 2 weeks through July 4. Harvest: 50 to 65 days from sowing. Why: Direct-sow only (no transplants needed), succession-plant for continuous harvest, fixes nitrogen for the soil. Care: Pick young and small for best texture; over-mature pods get fibrous.

Memorial Day Weekend Workflow
Friday: Soil delivery, bed prep, water deeply. Saturday morning: Cage tomatoes, install cucumber trellis, pre-plant fertilizer if using. Saturday afternoon: Plant tomatoes, peppers, cucumbers, basil. Sunday: Direct-sow bush beans, mulch around all transplants with 2 inches of straw, water in deeply. Monday: First-week deep water, walk-through inspection.
Watering Schedule for the First 30 Days
- Days 1–7: 1 gallon per plant every other day
- Days 8–21: 1 gallon per plant twice a week
- Days 22–30: 1 inch of water per week, applied deeply
After day 30, switch to a soaker hose or drip line. The Essex County soaker-vs-drip review covers the irrigation choice in depth.
