📝 Notes

Summer squash is an umbrella term for thin-skinned, immature-harvested squash including zucchini, yellow crookneck, pattypan, and straightneck. All are C. pepo. Harvest when skin is still tender (test with fingernail). Prolific producers. Squash vine borer is the deadliest pest — use row covers early, check stems for frass.
