They are fast to mature and have strong hybrid resistance to plant diseases. Their unusual colour makes them stand out like gems in the garden. The ripe fruits of Diana watermelon are extremely sweet and flavourful, and have few seeds. Diana scores 10.3 on the Brix scale, which means they are super sweet with complex flavour. When picked at the peak of ripeness, they are just incredible. So much more appealing flavour and texture than can be found in a grocery store melon.

How To Grow

Melon plants have sparse leaves and need a lot of sunshine and heat to mature their fruit. Their roots are delicate and require high nutrition and lots of water. For all that effort, you’ll be rewarded by the ripest, sweetest melons you’ve ever tasted. Follow along with this handy How to Grow Melons Guide and grow refreshing flavour this summer.!


Cantaloupes (musk melons) & Honeydews: Cucurbita melo
Watermelons: Citrullus lanatus
Family: Cucurbitaceae


Easy in a greenhouse or cloche, or outdoors in long, warm summers. Difficult without these conditions.

We Recommend: Halona Cantaloupe (ML500). The fruits are incredibly sweet, with a flavour that is out of this world. Plants are relatively productive, even without special growing conditions. Try Halona in a raised bed with lots of rich soil.
Season & Zone

Season: Warm season
Exposure: Full-sun
Zone: 4-10


It is essential to start seeds indoors or in a greenhouse mid to late April. Transplant at the end of May or first week of June, when the plants are 5 weeks old. Optimal soil temperature for germination: 20-25°C (68-77°F). Seeds should sprout in 5-10 days.


Sow seeds 1cm (½”) deep. Set transplants 60-90cm (24-36″) apart in rows 1.5-2m (5-6′) apart.


Ideal pH: 6.0-6.8. Choose a warm, well-drained soil. Add dolomite lime and compost or well-rotted manure to the bed and ½-1 cup of complete organic fertilizer beneath each transplant. Melons need really warm growing conditions. Use black plastic mulch, cloches, or floating row covers. Success may improve in raised beds. Melons plants require 8-10 weeks of good, hot growing weather from the middle of June to the end of August. During that time, a melon vine must grow 5-9 leaves before starting to flower, then set 4 or more male flowers before making its first female flower, and then ripen its fruit before cool, damp weather sets in. Melons do not ripen off the vine. During the entire growing season, make sure to provide ample water.


Fruit will ripen in late August to early September. Ripe cantaloupe will easily detach from the vine when light finger pressure is applied to the stem. Watermelon is ripe when the tendril nearest to the fruit withers and dries up.

Seed Info

In ideal conditions at least 60% of seeds will germinate. Usual seed life: 3 years. Per 100′ row: 60 seeds, per acre: 5.2M seeds.

Companion Planting

Melons are great companions for corn, marigolds, nasturtiums, pumpkin, radish, squash, and sunflowers. Avoid planting near potatoes. Melon leaves are full of calcium, so they’re good for the compost heap.
