Can epsom salts be used for growing pumpkins?

Question

I have been using epsom salts in the soil for my peppers with great results.My question is can I do the same for pumpkins?Will this lead to bigger pumpkins,which is what I would like.

Answer 1

If this is the case you should consider a soil test. If the epsom salts had a positive effect it indicates a problem that will effect your entire garden.

Epsom salts is hydrated magnesium sulfate (MgSO4). Its use as a soil amendment adds magnesium, used by the plant in the production of chlorophyll. If your soil is low in available magnesium (Mg) there are other possible problems that may also be present.
Dolomitic lime will add magnesium & calcium as well as sweetening the soil if your pH is low. (CaO (Calcium Oxide) 57.0%, MGO (Magnesium Oxide) 38.0%) Depending on your soil test this may be the recommended treatment because it is less soluble than Epsom salts it will stay with your soil longer.

To much potassium (K) leads to Mg deficiency in some plants, even with lots of Mg in soil. Potassium (K) interferes with root uptake of Mg. Adding nitrogen (N) or dropping K in soil will aid in this kind of Mg deficiency.
At pH extremes, some nutrients become partially or completely locked up in the soil and cannot be used by plants even though they are still present. For example, at pH 5 or below, calcium, magnesium, and phosphorus, for plant uptake, is locked up.
Extreme magnesium deficiency is recognized by pale green leaves with yellowing between the veins (chlorosis) on older leaves first and later on younger leaves.
and by blossom and fruit rot.
Pumpkin crop's optimal Mg at pH 6.5 is 100 ppm
Pumpkin has a slight acid tolerance in soil pH 5.8-6.8 with 6.5 optimal.
Pumpkin has high requirements for phosphate and potassium. Deficiencies even in the first 2-3 weeks will effect total yield.

Answer 2

Some minerals, such as calcium, potassium, and magnesium, are needed in relatively large amounts. They are called macronutrients. Other macronutrients include oxygen, carbon, hydrogen, nitrogen, and sulfur; these elements make up organic compounds.(from the web)

It will help epsom salt is a good source of potassium but a good balance of nutrients is recommended I would take some soil samples to your state agricultural dept or a unversity that offers that service they can tell you what you can use to further improve your yeild and quality.

Answer 3

I can*t understand how you can be getting good results from Epsom salts, because I use salt to kill weeds, unwanted grass, and poison ivy.
You put the salt on and when it rains it washes it into the soil8l and kills everything.

Answer 4

i mix just a little with everything once a year- and my pumkins and watermelons do tend to grow larger then without, but i have heard becareful not to use to oftes- cause it can have a negative affect and burn the plants.
