Vegetable Garden – Tips on Growing Melons From Seed



65-90 Days to Harvest





The question has always been- should I sow indoors or outdoors? In warm climates you can direct sow melons, however starting the melons indoors is preferred, both because the melon plants can grow well in soil that is 10-20 degrees cooler than that is needed for best germination of seed, and because the seeds germinate more slowly in cooler soil. Where ever you are, transplanting will probably give you the best yields in the finished crop. Remember that you will need to be very careful as to avoid transplant shock, Do not disturb the roots the best you can, also because melons need everyday of sun that they can get to ripen the fruit so they can not afford any setbacks.



  • Start melon seeds indoors in a seed starting mix three weeks before the last frost date. Sow 3 seeds each in 3-inch pots. Germinate at a steady 80º to 90ºF (27-32ºC). Once the seedlings appear, lower the temperature to 75ºF (24ºC) for about a week until the first true leaves begin to emerge. Thin to one plant per pot with scissors. Lower the temperature to 65º-70ºF (18-21ºC) and reduce watering for another week.
  • Days to Germination: 3-5
  • When soil temperature reaches at least 70ºF(21º)C, and after any danger of frost is past.
  • Sow 2-3 Melon seeds every 16", in a row, and cover ½" to ¾" deep in late spring, after any danger of frost.
  • Soil temperature should be 80-90º F(27-32º)C.
  • Cooler temperatures can cause the melon seeds to rot.





A warm weather crop that should not be planted too early in the spring.





  • pH range: 6.0-7.0 where 6.0 is the absolute minimum, production drops below this.
  • Growing soil temperature: 70-85º F (21-29º)C.
  • Spacing in beds : 16" (40cm)
  • Watering: Moderate and even from germination to hardening off, low for one week prior to transplanting, moderate again from transplanting until fruit is full sized, low or none during ripening of fruit.
  • Light: Full sun
  • Nutrient requirements: N=low, P=high, K=high


Rotation considerations:



  • Avoid following cucumber, pumpkin, and summer and winter squash.<.li>
  • Good Companions: Corn
  • Bad Companions: Potato

An old garden myth would suggest pinching off a vine’s growing shoots as melons start to ripen to cause the plant to divert all its energy to the ripening fruit. Research has proven this FALSE. The vine needs all its leaves to produce the sugars that sweeten fruit. Anything that reduces the total number of leaves available for sugar production reduces melon sweetness.



The more fruits that ripen at the same time, the less sweet they will be, this is TRUE, since the vine will have to divide the leaves’ sugar production between fruits. In warmer climes with a long growing season, experienced growers often prune off all but one newly forming melon every 2 weeks. Ripening 1 melon at a time yields maximum sweetness. As you gain experience, you will develop your own technique.



In colder regions, remove any blossoms that start to develop within 50 days of your area’s first average frost date. This ensures remaining, larger fruits will ripen before frost.



The key to a sweet melon is lots of sugar, which is made by the leaves. So anything that hurts the leaves also hurts the quality of the fruit.






  • Melons are sensitive to drought throughout the season, but especially from transplanting to fruit set. To get fruits of the proper size, water evenly but not too much, as too much water when fruits are enlarging can diminish flavor.
  • If possible, avoid overhead watering. Soaker hoses deliver water directly to the soil, preventing possible spread of fungus diseases on wet foliage. If you must use a sprinkler, then water vines very early in the morning so that leaves can dry early, which helps prevent fungus diseases.
  • Melons grow quickly and sometimes outgrow the nutrient reserve in the soil, if this happens your leaves will be a light green, so to correct this use a complete organic fertilizer like fish emulsion or kelp from time of transplant to fruit set.
  • Plant in rich well composted soil. Before the vine spread apply mulch to control weeds.
  • For vines running on the ground, keep fruit from direct contact with soil to prevent rot and protect fruit from pests and rodents. Place ripening fruit on mulch, upturned coffee cans, or flowerpots. If large critters such as groundhogs discover your melons, protect ripening fruits by covering them with plastic milk crates or similar boxes weighted down with a few bricks.
  • After transplanting in spring you can cover plants with floating row covers to exclude insects and trap warm air near plants; this is most important in cooler climates but is useful everywhere to keep certain pests off the plants. Vines bear male and female flowers. Male flowers open first, joined by female blossoms about a week later. Female flowers have a small swelling at the base of the flower. When vines start to bear male and female flowers, remove row covers.






It is normally pretty easy to tell when most vegetables are ripe, however melons require a little more practice to get it right. A good tip to know is that all the fruits on any individual melon plant will ripen over a short period of time. When one melon is ripe, the remaining melons are not far behind.



  • MOST MELONS (with the exception of Watermelons) are ripe when the rinds change from a gray-green to yellow-buff color. The fruit is firm but with gentle thumb pressure you can easily separate the stem from the vine.
  • WATERMELONS: Gauging when to pick a watermelon is a combination of science and tradition. Here are the most popular ways to determine when your watermelon is ripe.
  • The tendril nearest to the fruit will turn from green to brown.
  • The underside of the melon, where it sits on the ground is yellow.
  • When you rap it lightly you will hear a low pitched thunk or thump instead of a high pitched ping. Try this out on a few that are NOT ripe so you can tune your ear to the sound.
