Needs long hot season β challenging in northern climates. Choose short-season varieties. Tap fruit and listen for a hollow sound to check ripeness. Grow under cover in cool climates.
Cucumis melo var. inodorus
A fellow Cucurbitaceae β similar growing habits to Watermelon
Start Watermelon indoors about 4 weeks before your last frost, keeping seeds in warm soil (around 20β25 Β°C). Seeds usually come up in around 7 days. Move seedlings out once the danger of frost has passed, in full sun, spaced about 150 cm apart. Expect to harvest in roughly 90 days.
Syrphidae
The adults only drink nectar. It is the larvae that eat the aphids.
Water: High Β· Height: 30 cm Β· Soil: Rich, well-draining, warm β needs heat
Watermelon seed rarely stays viable beyond 4 years β track what's still worth sowing.
These three thrive alongside Watermelon β and alongside each other.
