How to Grow Vegetable Marrow (Long Green Trailing)

Cucurbita pepo 'Long Green Trailing'

Vegetable Marrow is a trailing heirloom squash prized for its long, slender fruits that trail across the ground rather than climbing high trellises.

Soil, care & harvest

Prepare loose, well-draining soil with a pH between 6.0 and 7.5 before sowing seeds directly outdoors. As a warm-season crop, wait until after the last spring frost when the soil is fully warmed; do not start indoors as it does not tolerate transplanting well. Sow seeds about one inch deep in rows spaced 60 to 72 inches apart. Expect germination within seven to ten days under these warm conditions.

Space trailing vines widely so they can spread eight to twelve feet without restriction. Provide consistent moisture, aiming for two to three inches of water weekly as fruits develop. Apply a thick layer of mulch around the base to retain soil warmth and suppress weeds. Feed lightly if leaves turn yellow, but avoid over-fertilizing which can reduce fruit quality.

Watch closely for squash bugs, cucumber beetles, vine borers, and slugs that attack foliage and stems. Prevent powdery and downy mildew by ensuring good air circulation and avoiding overhead watering in humid weather. Harvest fruits when they reach mature size, typically sixty to eighty days after sowing, by twisting them gently from the vine.
