Seed treatment
Buy seed treated with Thiram or captan seed protectants.
Soil temperature
The minimum soil temperature required for germination of these crops is 16°C with the optimum range between 21 and 35°C.
Planting
Slicing-cucumbers and zucchini are often started in plug trays in greenhouses 3 to 4 weeks before transplanting outdoors. Approximately 2.25 kg of seed will provide enough transplants to plant 1 ha (0.9 kg/acre). Do not transplant until all danger of frost has passed unless row covers are used.
For direct-seeding of cucumbers, 4.5 to 5.5 kg/ha (1.8 to 2.2 kg/acre) of seed are required if seeding is to be done in the field without the use of a precision seeder.
Pickling cucumber varieties are usually direct-seeded, but transplants may be used where earliness is important. Seed at a depth of 1.5 to 2.5 cm depending on soil moisture, and use 2.25 to 2.75 kg/ha (0.9 to 1.1 kg/acre) of seed.
Muskmelons and watermelons are usually started in greenhouses 5 weeks prior to the date for transplanting.
Pumpkins and squash are usually direct-seeded when all danger of frost has passed.
Growing cucurbits using plasticulture provides many benefits. See the "Plasticulture" section of the Vegetable Production Guide: Planting (PDF).
Final Spacing | Between Rows | Within Row |
---|---|---|
Slicing cucumbers | 1.2 to 1.8 m | 30cm |
Pickling cucumbers | 1.2 to 1.5 m | 20cm |
Muskmelons | 1.5 to 1.8 m | 90cm |
Watermelons | 1.8 to 2.4 m | 120cm |
Pumpkins | 1.8 to 2.4 m | 90cm |
Squash | 1.8 to 2.4 m | 90cm |
Fertilizer
A soil test is necessary to determine lime, phosphate and potash requirements. Use the Vegetable Production Guide: Nutrient Management (PDF) for recommendations based on soil test results.
The optimum pH range is 5.8–7.0.
Prior to planting, broadcast and disc in 70 kg/ha (28 kg/acre) nitrogen and all of the required potash and phosphate. Alternatively, all of the phosphate and up to 100 kg/ha (40 kg/acre) in total of nitrogen plus potash may be banded at planting with the balance broadcast before planting.
Just before vines begin to spread, side-dress with 40 kg/ ha (16 kg/acre) of nitrogen or if mulching and trickle irrigation are used, nutrients should be delivered by fertigation. See the "Fertigation” section of the Vegetable Production Guide: Planting (PDF).
Pollination
Vine crops bear both male and female flowers. Only the female flowers set fruit. Bees transfer pollen from male flowers to female flowers, making fruit set possible. In small plantings there are often enough native bees to ensure adequate pollination. In larger plantings, it is often necessary to introduce one honey bee colony per hectare at bloom.
For more information, review the Bee Poisoning warning in the Vegetable Production Guide: Pest Management (PDF, 1.2 MB).
A black plastic or wavelength selective mulch provides excellent weed control and other benefits. See the “Plastic Mulches” section of the Vegetable Production Guide: Planting (PDF).
Broadleaf weed control with herbicides is very difficult in vine crops. Growers should consider using the stale seedbed technique in the Vegetable Production Guide: Planting (PDF) to provide control of the first flush of weeds. The herbicides listed in the tables below are also registered, but have a very limited broadleaf weed spectrum.
As these crops are usually planted in wide rows, herbicides can be applied in a narrow band over the row (e.g. 30 cm) to reduce chemical cost. Cultivation can be used to control weeds between the rows.

Aphids
Aphids are soft-bodied, sucking insects, yellowish-green to black in colour, clustered on growing tips of plants or under leaves. Severe infestations cause premature death of plants, resulting in lack of sizing of pumpkins and squash. Aphids excrete honeydew, causing growth of sooty mould. They can also transmit viruses.

Spidermites
Spidermites are tiny, 8-legged, spider-like animals. Their feeding causes leaves to become dry and bronzed with yellow and brown spots and covered with a fine webbing. Mites increase in number rapidly during hot, dry weather. There are several native predators, but these may not build up fast enough to keep mite levels in check.

Springtails
Springtails are small, black, white, or gray, wingless insects. They have a forked appendage attached under the rear end of the abdomen, which is held there by a clasp. When this appendage is released the insect jumps like a flea. Normally, springtails remain in the soil, near the roots or plant crown, as they feed on organic matter. Their feeding on young cucumber plants causes brown spots on the leaves; sometimes the plants are stunted.
Thrips
Small (1 mm), slender insects which feed on leaves causing speckling leaves. Good weed control prevents heavy buildup of thrips. Chemical control is not generally required.

Alternaria leaf spot
This disease occurs after cool, wet spells and causes numerous small, round, dead spots on leaves. It is most prevalent during hot, dry days combined with dewy nights. Leaves and stems may be killed but there is no spotting of fruit.
Beginning when the disease is first observed and at 7 to 14 day intervals thereafter, apply one of the products listed in the table below. Bravo 720, Bravo ZN or Bravo ZNC sprayed for scab and powdery mildew may also control Alternaria leaf spot.

Verticillium wilt
The causal fungus is soil or seed-borne. First, lower leaves wilt and drop, then petioles turn yellow and wither and, finally, the entire plant may wilt. It is usually worse on light, sandy soils in the Interior, and where root lesion nematodes are also present.
White mould
(Sclerotinia)
Fruit becomes covered with white cottony mould, and later small black hard bodies (sclerotia) appear in the rotting tissue. Stems can also be blighted; older vines are more often affected.
Root rot
RootShield WP (Trichoderma harzianum Rifai strain KRL-AG2) is a biological fungicide for the suppression of Root Rot in greenhouse vegetable transplants. When applied to transplants, greenhouse planting mix or soil, the product grows into plant roots as they develop to protect roots against Pythium, Rhizoctonia and Fusarium.
