[Market-farming] Espom salts on melons?

Many melons are grown in sand, which may be low in Mg. Mg plays a role in photosynthesis, so may influence the production of sugars. Soil tests usually tell you if Mg is low or adequate. If adequate, Epsom salts might help, might not. I see it as optional unless you are truly low in Mg. If you make plenty of compost and use it in your melon plots, you probably have enough Mg. Using Epsom salts shouldn't hurt anything. If your soils has a dolomite lime bedrock base, you probably have high levels of Mg.

Hi, Folks!

Since everyone seems to want to talk about something, I thought I’d toss a question out here.

Saw in Nolte’s Produce Supply catalog the notation that “spray your melons with Epsom salts to make them sweeter.”

Never done this – I’ve added Epsom salts to the planting hole for peppers and tomatoes and seen a real improvement in fruiting, but hadn’t heard about this for melons.

Do people do this?  In the planting hole and/or foliar feeding when the melons are about ripe?

Discuss and thanks for your input!
