Correct soil ph for muskmelons and watermelons

edweather(Zone 5a/b Central NY)August 2, 2008

I'm already thinking of my garden for next year and have been researching ph requirements for melons. Almost every source suggests a ph of 6.5 to 7 for both watermelons and muskmelons. Amy Goldman, in her book suggests an alkaline ph of 7 to 8 for muskmelons. She's supposed to be an authority on the subject, but the only one who says this. I've had pretty good results this year with soil around a neutral ph of 7 for watermelons and muskmelons, but would like to tweak it in the proper direction next year. Any thoughts?? Thanks.

Forget about what this or that author says. Most anything you ever will want to grow will do fantastic at a neutral pH. Get yourself a soil test at a lab and check out the calcium and magnesium levels. If they are low then you can certainly add some lime to add them and lower pH at the same time, but a neutral pH is just fine for most things.

if you have lots of organic matter in the soil the ph does not matter. the ph is more important only with hydroponic. you are not growing hydro so forget it. get more compost into the soil. organic matter is what counts not ph.

The local microscopic level ph will vary with the decompositon of the organic matter. it will vary with the moisture level. the only important thing for ph is that all the elements are available to the plant. elements are available over a broad range of ph.

hydro ph is different than soil ph. you do not want to grow in soil at the best hydro ph. it is apples and oranges.

Concur with Justaguy and Dangold. Melons (c.melo) cantaloupes, Crenshaws, Honey Dews and Spanish melons)are are not especially choosy about pH. They grow well from pH 5.5 to 7, maybe even higher, but the highest pH that I have encountered in the east is 7.
