📷 Wikimedia CommonsStarting Sugar Baby Watermelon: indoors or direct sow?
🌾 Sow directly in the garden — Sugar Baby Watermelon is not usually started indoors.
This variety is direct-sown only; do not transplant seedlings indoors or outdoors before the soil has warmed completely after the last frost.
Soil, care & harvest
Prepare loose, well-draining soil with a pH between 6.0 and 7.0. As a frost-sensitive warm-season crop, you must wait until after the last spring frost when the ground is fully warm to sow directly outdoors. Do not start indoors; seeds should be planted directly into their final location at a depth of about one inch. Expect germination in seven to ten days.
Space plants three to four feet apart to ensure proper air circulation and fruit development. Provide consistent moisture, aiming for one to two inches per week with deep watering to prevent cracking. Apply organic mulch around the base to retain soil moisture and suppress weeds, but keep it away from the vines.
Watch for cucumber beetles, squash bugs, aphids, and spider mites; use row covers or insecticidal soap early. Prevent powdery mildew and downy mildew by ensuring good airflow and avoiding overhead watering. Harvest ripe fruit approximately seventy-six days after planting when the rind turns dark green and dull to the touch.
