🌾 Sow directly in the garden — Yellow Scallop Pattypan is not usually started indoors.
Direct sow seeds outdoors only after the last spring frost once soil temperatures have warmed sufficiently for germination.
Soil, care & harvest
Prepare loose, fertile soil with a pH between 6.0 and 7.0. As a warm-season crop, you must wait until after the last spring frost when the soil is thoroughly warm before planting. Sow seeds directly into the ground at a depth of about one inch. Expect germination to occur within seven to ten days under these ideal conditions.
Space plants thirty-six to forty-eight inches apart to ensure proper air circulation and growth. These compact varieties do not require trellising but benefit from consistent moisture, aiming for one to two inches of water weekly. Apply mulch around the base to retain soil moisture and feed the plants regularly to support vigorous vine development.
Watch for squash bugs, cucumber beetles, aphids, powdery mildew, bacterial wilt, and mosaic virus. Prevent issues by inspecting leaves frequently and practicing crop rotation. Harvest the yellow scallop fruit fifty to fifty-five days after sowing when they reach full size and vibrant color.
