I planted watermelons, cantaloupes, and pumpkins this year. I've already harvested a watermelon and cantaloupe (one each), but am discouraged by the tiny fruits. Should I be using manure to help size things up? I broadcast 10-10-10 fertilizer, but didn't add any manure. Does manure make that much difference? And if so, should I use a particular type (chicken, cow, whatever)?
Variety is the most important. If you want big melons plant a big variety.
Space is very important. The larger varieties need a minimum of 64 square feet per plant.
Preparation: watermelons demand a loose soil. a sandy loam is best. Heavy clay they really don't like. It also has to be deep. Cantaloupes are more tolerant of heavy soils.
Fertilization. Watermelons are not heavy feeders. I have had nice ones from volunteers in fence rows. I use 10-10-10 at 300 lbs per acre. Manure or compost is excellent if you have it. It serves also as a soil conditioner and a loose friable soil is essential. Cantaloupes feed a bit heavier than watermelons. Chicken manure is nitrogen heavy and can cause excessive vine growth to the detriment of setting melons. http://s294.photobucket.com/user/farmerdill/library/Watermelon?sort=9&page=1http://s294.photobucket.com/user/farmerdill/library/pepper/Cucumis%20Melo?sort=4&page=1
Very long melon. 40 to 50 lb. The flesh is bright crimson, fine grained and very sugary. Tough rind: rich dark green with faint stripe. Can be shipped succesfully. Used to be grown extensively in the South. 90 DTM.
