Watermelons are vining plants that produce large, sweet, juicy fruits. They love warm weather and plenty of space to sprawl across your garden. You will need a long, hot growing season to get the best harvest.

Pflege

Provide consistent moisture while the fruit is developing, but reduce watering as harvest approaches to concentrate sweetness. Watch for powdery mildew on the leaves and ensure the vines have plenty of room to spread. Harvest when the underside of the melon turns from white to a creamy yellow.

Gießen
Keep the soil consistently moist but not waterlogged during the active growth phase.
Düngen
Apply a balanced fertilizer early in the season and switch to a low nitrogen formula once flowers appear.
Schneiden
Trim back excessive vine growth if the plant is taking over your entire garden space.

Watermelons are annuals and are typically grown directly in the ground rather than in pots.

Standort und Pflege

Vermehrung
seed
Pflanzzeit
Spring
Überwinterung
This plant is an annual and will die with the first frost, so there is no need to overwinter it.
Im Kübel
It grows well in large containers of at least 20 liters, provided you use a strong trellis for support.

Direct Sowing

  1. Wait until the soil is warm and all danger of frost has passed.
  2. Plant seeds 2 to 3 centimeters deep in mounds of rich, well-draining soil.
  3. Space mounds at least 1 to 2 meters apart to allow for spreading vines.

Planting aromatic herbs like dill nearby can help mask the scent of the vines from pests.

Gute Pflanzpartner

  • Radish — Radishes can help deter cucumber beetles that often plague watermelons.
  • Kapuzinerkresse — These flowers act as a trap crop for aphids and attract beneficial pollinators.

Fernhalten von

  • Potato — Potatoes compete heavily for soil nutrients and can harbor blight that affects cucurbits.

Ähnliche Arten

  • Gurke — They share similar growth habits and pest vulnerabilities.

Häufige Fragen

How do I know when a watermelon is ripe?
Look for the field spot on the bottom to turn creamy yellow and the tendril near the stem to dry out.
Can I grow these in containers?
Yes, but you need a very large container and a sturdy trellis to support the heavy fruit.

Woher der Name kommt

The name Citrullus is a diminutive of Citrus, referring to the fruit's resemblance to a small orange, while lanatus means woolly, describing the fine hairs on the stems.

Gut zu wissen

  • Watermelons are roughly 92 percent water.
  • The heaviest watermelon on record weighed over 350 pounds.
  • Ancient Egyptians placed watermelons in tombs to provide nourishment in the afterlife.
