Description

(Citrullus lanatus). The sugar-sweet, tangerine flesh of this one will knock your socks off! Perhaps the most perfectly flavored watermelon we have tried! In 2008, Mike Kiessel, watermelon expert of Leelanau County, Michigan, decided to cross the Orangeglo watermelon with a Crimson Sweet. After years of selecting and perfecting, the Leelanau Sweetglo has completely won our hearts and triumphed at our annual tasting trials! A favorite early-maturing, orange-fleshed variety excellent for northern growing.

Growing Guide

When to Grow

Start seeds indoors 3–4 weeks before the last frost or direct sow after soil temperatures reach 70°F. Transplant outdoors only after the last frost has passed and nights remain consistently above 55°F. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Sow 2–3 seeds per hill, 1 inch deep, in mounded soil for improved drainage. Space hills 3–4 feet apart and thin to one strong seedling per hill. For row planting, space plants 3–4 feet apart in rows 5–6 feet apart. Avoid planting in soil where other cucurbits were grown the previous season.

How to Grow

Water deeply once or twice per week depending on rainfall, and reduce watering as fruits mature. Apply balanced organic fertilizer at planting and again when vines start running. Use row covers to protect seedlings from pests early on, removing them when flowering begins to allow pollination.

How to Save Seeds

  • Allow fruit to ripen fully and cure on the vine before harvesting.
  • Scoop seeds from the flesh and rinse in a strainer to remove pulp.
  • Spread seeds on a screen or paper towel in a warm, dry place out of direct sunlight for 7-10 days.
  • Stir daily to ensure even drying.
  • Once completely dry, store in an labeled, airtight container in a cool, dark place.
