Growing Cantaloupe at Home For Summer Harvests

Sweet and nutritious melons are an enticing sight in summer gardens. From cantaloupe and honeydew to Crenshaw and casaba varieties of Cucumis melos, these culinary masterpieces pack in flavor while providing essential vitamins and minerals.

They thrive best in warm soil with ample sunshine. Before planting, an appropriate soil test can help determine your garden bed’s individual nutrient requirements.

Soil

Cantaloupe and other cucurbits, including watermelons, squash, and cucumbers, require warm soil with high levels of organic matter and balanced levels of nitrogen, phosphorus, and potassium for rapid growth and optimal size development.

Before planting, amend your soil with compost or well-rotted manure and till into an even bed before smoothing with a harrow or smoothing blade. While disked planting beds are best suited to this method of cultivation, raised beds may also work effectively. A layer of straw or hay may help prevent erosion while keeping temperatures down until seedlings have taken hold and established themselves on the soil surface.

Garden soil testing can help identify both the pH level of the soil and how much nutrients are necessary. Melons generally perform best in soils between 6.0 and 6.5 in terms of acidity levels; should your results indicate too acidic an environment, adding lime is suggested to increase its alkalinity levels.

Fertilizers containing ammonium, nitrate and/or phosphate must contain sufficient nitrogen, phosphorus and potassium for healthy plant development. A balanced fertilizer such as 10-10-10 or 15-15-15 would be the optimal choice; overfeeding could interfere with sugar production causing unripe melons that rot prematurely.

Soil must be free from disease to ensure a good harvest. Fungus diseases, including Alternaria leaf spot, gummy stem blight, downy mildew and powdery mildew infestations, can damage or destroy vines or fruit and can only be controlled using approved fungicides approved for use on melons crops.

To reduce fungus and insect issues, plant in areas that haven’t had melons or other cucurbits grown in them for three years or that has not been exposed to herbicide spraying for at least 12 months before starting any new crop. Cantaloupe beetles such as the striped and spotted cucumber beetle pose particular danger as they carry bacteria responsible for bacterial wilt, which causes vines to shrivel up and die off quickly. Row covers can help deter beetles but must be removed once blooms start appear so pollination can take place effectively.

Temperature

Cantaloupe (Cucumis melo reticulatus), one of the world’s juiciest orange melons, belongs to the same plant family as watermelons, honeydew melons, and squashes. Cantaloupes are easy to grow and even easier to devour – their sweet, delicious summer fruit boasting a net-like rind makes this fruit one of the juiciest on the market with around 90 percent water content making them one of the juiciest treats on offer this year.

Cantaloupes thrive best on warm soils that drain well and contain organic matter, and require little fertilization for optimal growth. A soil test prior to planting is key to determining how much and which kind of fertilizer you’ll need for maximum success; growing cantaloupes in raised beds allows drainage while reducing soil compaction.

Use a shallow tillage tool to loosen and mix the soil before planting to avoid clumping of seeds and promote even germination. Aim for planting 1/2 to 1 inch deep; optimal planting times in southern Oklahoma would be late March/early April while for northern areas it should be closer to mid-April when ground temperatures exceed 60 degrees Fahrenheit for quicker germination rates.

As an aid to transplanting, lightly cover each row of seeds or transplants with a thin layer of compost or other soil amendment. A layer of mulch also helps retain moisture and limit weed competition while protecting soil from frost damage which may be an issue in some regions of the state.

Melons need an extended growing season and can be susceptible to frost damage, making frost cloth or plastic film an invaluable way of protecting them.

One week prior to harvest, reduce watering levels so as only enough is used to prevent vine wilting – this allows sugars to concentrate in the melons for maximum sweetness and enhances their sweetness.

Cantaloupes should be harvested when their rind color transitions from gray-green to yellow-buff and the netting becomes more distinct. When at its full slipperiness, cantaloupe will release easily from its stem.

Fusarium wilt, anthracnose and powdery mildew can greatly impede production of premium cantaloupes, making harvest time difficult. For more information on identifying and controlling such diseases in Cucurbit vegetable crops please consult OSU Extension Circular E-853 Cucurbit Production and Pest Management or E-929 Guide for Identification and Control Diseases of Cucurbit Vegetable Crops from OSU Extension Circular E-853 or E-929 respectively.

Water

Cantaloupe plants thrive when provided with sufficient water throughout their growth season to prevent vine wilting and stimulate vigorous plant development. Well-drained soils with lots of sunshine provide optimal conditions, as this warm season crop cannot tolerate frost or cool temperatures. Gardeners can extend production by using black ground covers to warm soil temperatures as well as floating row covers to trap warm air around their plants.

Cantaloupe seeds may be directly planted after all risk of frost has passed and soil temperatures have warmed in warmer climates, while in colder regions indoor starting should begin 4-6 weeks prior to average last spring frost date before being transplanted outdoors two to three weeks later – ideal planting times being late March for Southern Oklahoma areas and mid April in northern areas.

Seeds should be planted 1/2 inch deep. Soil temperatures of 65degF or higher are required for optimal germination, typically occurring 7 to 10 days later. On sandy or dry soils, adding organic material mulch helps retain moisture; gardeners may then need to thin newly established young plants down to three or four per foot after they become established.

To reduce diseases, weeds, and insects in their garden, gardeners should prepare the soil by mixing in large quantities of organic matter prior to planting. Tilling or smoothing harrows are helpful tools when working this material into the ground; raised beds may be more suitable in cases where soil conditions are particularly challenging.

Cantaloupe plants are highly sensitive to fertilizer burn, so a preplant application of 50 lbs N/A is generally advised. Nitrogen should be sidedressed after planting and additional applications may be necessary if heavy rainfall causes leaching of light-textured soils.

Once the melons are ripe, it should be harvested quickly before they overripe and start turning yellow. A successful harvest can be ensured by checking daily to see when it’s ready; melons are considered ready for consumption when their outside surface becomes netted and their green hue turns yellow.

Pruning

Pruning cantaloupe vines is essential when growing cantaloupe at home. Cantaloupe needs well-drained, warm soil that’s rich with organic matter as well as ample sunlight in order to produce large, sweet fruits that taste amazing. Pruning needs to occur early so as not to hinder productivity and yield.

Seeds should be planted indoors four to six weeks prior to the last frost date in your region and transplanted outside once all risk of frost has passed and soil temperature reaches at least 70degF. Container planting can help the plants develop to their full size before being moved out into your garden.

Cantaloupe vines can spread out rapidly, so they require plenty of room. Plant your seeds 36 to 42 inches apart either in rows or hills in your garden or container which can accommodate their mature size. Before adding seeds, incorporate several inches of well-rotted composted manure into the planting bed as a source of nutrition; additionally a balanced organic fertilizer may provide added benefit.

As soon as your plants produce fruit, restricting the number of ripe melons per vine is key to improving size and flavor. For maximum success, only one melon should appear on each main lateral stem for best results – this may require some light pruning.

Cantaloupe vines should be pruned between mid- to late spring and summer, when most gardeners prune their melons vines. At this time, watering should be limited to ensure maximum fruit ripening instead of vine and leaf growth – which in turn will reduce disease problems.

If your cantaloupe crop is susceptible to disease, choose resistant varieties with resistance against powdery mildew and Fusarium wilt. Other diseases that could impact cantaloupe include nematodes, cutworms, thrips, cabbage loopers – these pests often require treatment with neem oil spray for effective defense against these potential threats.

Once a melon has reached full ripeness, its color will change and it will feel heavier than fresher varieties. When picking and harvesting it for consumption, ensure your hands are clean to avoid contamination as well as to wash its rind thoroughly to remove any dust that might have settled there.
