Contact your Cooperative Extension Service for fungicide recommendations. Burpee Recommends: Avoid powdery mildew by providing good air circulation for the plants by good spacing and pruning. The leaves appear to have a whitish or greyish surface and may curl. Powdery Mildew: This fungus disease occurs on the top of the leaves in humid weather conditions. Contact your Cooperative Extension Service for recommendations. Control cucumber beetles, which spread the disease. Burpee Recommends: Remove and destroy plants showing signs of the disease. Burpee Recommends: Provide sufficient space between plants for good air circulation, avoid overhead watering which can spread the fungus spores, keep a clean garden, remove and discard all diseased plant material and rotate crops.īacterial Wilt: Leaves turn brown, stems wilt and shrivel, the infected plants die. The fungus overwinters in diseased plant debris. Extended periods of heat and humidity facilitate anthracnose growth. The spots enlarge and turn black the fruit rots. Infected fruit develop sunken black spots that may have white mycelia during wet weather. Irregular brown spots develop on the leaves. Contact your Cooperative Extension Service for fungicide recommendations.Īnthracnose: This is a fungus disease that attacks the fruit as it is ripening. Remove infected plant parts and do not work around wet plants. Burpee Recommends: Avoid getting water on the foliage. This disease is worse in warm, wet or very humid weather. Fruit are not usually infected but can suffer from sunscald due to leaf loss. Severely infected leaves turn brown, curl upward, wither and die. Check with your local Cooperative Extension Service for pest controls recommended for your area.Īlternaria Leaf Spot: Small, round reddish brown spots, usually with a yellow halo, form on the upper surface of the leaves.

Keep plants well-watered during the growing season, especially during dry spells.Cantaloupes have a shallow root system, mulches help retain soil moisture and maintain even soil temperatures.Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating. Keep weeds under control during the growing season.Thin to 3 or 4 strongest seedlings in each group when they are 1-2 inches high.Sow seeds 3 inches apart in groups of 4-6.Sow in fertile, warm soil after danger of frost has passed.This hardening off process toughens the plant’s cell structure and reduces transplant shock and scalding. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning. Be sure to protect them from wind and hot sun at first. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week.

Before planting in the garden, seedling plants need to be “hardened off”.Seedlings do not need much fertilizer, feed when they are 3-4 weeks old using a starter solution (half strength of a complete indoor houseplant food) according to manufacturer’s directions.Most plants require a dark period to grow, do not leave lights on for 24 hours. Incandescent bulbs will not work for this process because they will get too hot. Raise the lights as the plants grow taller. As soon as seedlings emerge, provide plenty of light on a sunny windowsill or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night.Sow seeds ½ inches deep in seed-starting formula.Direct sowing is recommended, but to get a head start you can grow cantaloupe indoors 3-4 weeks before the last frost in individual biodegradable pots indoors.
