Planting Guide

Shallow lettuce roots complement deep beet roots

Lettuce provides ground cover under cucumber trellises

Kale provides partial shade for lettuce in warmer weather

Radishes mature fast, mark rows for slow lettuce germination

Both prefer cool weather and partial shade

Different growth habits allow efficient interplanting

Both brassicas attract identical pests, concentrating damage

Different nutrient needs reduce competition

Kale provides beneficial shade for lettuce

Both cold-hardy; extend harvest season together

Both brassicas share cabbage worm and flea beetle pests

Different growth habits and root depths

Both tolerant of cooler weather

Tomatoes repel flea beetles that attack collards

Radish roots break soil crust for beet seedlings

Radishes deter cucumber beetles

Radishes deter striped cucumber beetles from melons

Fast radishes mark slow-germinating spinach rows

Radishes repel squash vine borers

Both root vegetables but different nutrient needs

Lettuce provides shade; carrots aerate soil for lettuce roots

Fast radishes mark slow carrot rows and break soil crust

Different root depths complement each other

Different root depths, similar growing conditions

Mustard greens can stunt beet growth

Both cool-season crops with compatible needs

Both root crops, can share space but no strong benefit

Both brassicas share same pests

Radishes mature first, leaving space for turnips

Both cold-hardy, different root depths

Both brassicas attract same pests

Both cool-season greens with complementary growth

Different root depths complement each other

Both prefer cool, moist conditions

Compatible growing requirements

Both attract tomato hornworm/corn earworm

Both are heavy feeders competing for similar nutrients

Carrots loosen soil around tomato roots; tomatoes shade carrots

Lettuce provides living mulch, tomatoes provide shade

Same family, similar water/nutrient needs, easy to manage together

Radishes attract flea beetles away from tomatoes

Spinach acts as living mulch under tomato canopy

Can coexist but compete for water; both need staking

Different root depths use space efficiently

Both nightshades with compatible growing requirements

Both thrive in heat, similar water needs

Spinach shades soil, retains moisture for peppers

Nightshade family, same growing conditions

No strong interaction, can share space

Lettuce shades soil around eggplant base

Both thrive in hot conditions

Both nightshades with compatible growing requirements

Spinach provides ground cover under eggplant

Okra grows tall, cucumbers spread below

Both love heat and similar water needs

Okra grows vertically, melons spread as ground cover

Same cucurbit family, share squash vine borer and powdery mildew

Corn provides shade and natural trellis support

Lettuce shades soil under cucumber trellises

Radishes deter cucumber beetles

Both Cucurbita species can cross-pollinate affecting seed saving

Same species share all pests and diseases

Traditional planting guild: squash shades soil, corn provides structure

Radishes repel squash vine borers

Harvest spinach before squash vines spread

Same genus, cross-pollination affects seed saving

Zucchini acts as squash in Three Sisters guild

Radishes deter squash bugs from zucchini

Spinach harvested before zucchini spreads

Both aggressive sprawlers compete for space

Traditional guild: pumpkin shades soil, corn provides structure

Radishes help deter squash bugs
