How to Start It
★ Recommended for beginners
Melons need warmth, so wait until 1 to 2 weeks after your last frost, when the soil has reached about 18°C (64°F). Sow 2 to 3 seeds 2 cm deep in a small mound of compost-rich soil, 60 cm apart, and they sprout in 5 to 10 days. Keep the strongest seedling at each spot, and cover the mound with row cover on cool nights to give it a boost.
Honeydew is a melon that needs a long, warm summer, so in cooler places a head start indoors and your warmest spot make the difference. Unlike cantaloupe, it does not fall off the vine when ripe, so you judge it by colour, feel and smell.
When To Start
Honeydew needs warmth. Wait until your last frost has passed and the soil has warmed before sowing.

Growing Tips
- 1Plant honeydew in your sunniest, warmest spot, ideally against a south wall or in a raised bed that warms up fast.
- 2Mix plenty of compost into the soil, since melons are hungry plants.
- 3Water deeply at the base about once a week while the vines grow, then water less once the fruit is full size so the flesh turns sweeter.
- 4Feed with worm castings or compost tea when the vines start to run and again when the first fruit sets.
- 5On a trellis, hold each growing melon in a cloth sling, and on the ground, set it on a board or mulch to keep it clean.
- 6Cover young plants with row cover against cucumber beetles until the flowers open, and keep the leaves dry to slow powdery mildew.

When to Pick
Ripe at 'full slip': the fruit detaches from the vine with a gentle push, skin pales and smells sweet
How to Harvest
- 1A honeydew is ready when the rind changes from green to creamy white or pale yellow and feels a little waxy instead of fuzzy.
- 2The end opposite the stem gives slightly when pressed and smells sweet.
- 3The melon does not slip off the vine on its own, so cut it with a short piece of stem.
- 4Melons do not get sweeter after picking, so wait for those signs.
- 5Keep a whole ripe honeydew on the counter for a few days, and keep cut pieces covered in the fridge.
Step 5
Saving Seeds
How to Save Seeds
Honeydew crosses with cantaloupe and other melons, but not with watermelon, cucumber or squash. To keep it pure, grow just one melon variety, and remember hybrid F1 seeds will not grow true. Scoop the seeds from a fully ripe melon, rinse them in a sieve to remove the pulp, and throw out any that float. Dry them on a plate for 1 to 2 weeks, then store them labelled somewhere cool, dark and dry, where they keep about 5 years.
