New member needs help with watermelon

[Rush2112]

I planted 2 icebox watermelon plans about 3 weeks ago.

They were both growing well but recently 1 started going downhill.

They both get the same amount of sun and water.

Here in Boise Idaho the weather has been pretty bad the last week or so…… rainy and cold... highs in the mid 70’s lows in low 50’s high 40’s. Before that we had highs in the upper 80’s lows in the 60’s.

Here they are





Any idea whats wrong???

Thanks.

Lots of parts of the US have had cool wet springs. It is perfect weather for encouraging fungus problems. At a guess, I'd say that's what happened to yours, some kind of fungal blight or wilt. If you want to try to save it you could try spraying it with a solution of milk and water (any where up to 59-50 at this point trying to save a dying plant; organic milk with active lactobacillus is best) or a baking soda and water solution.
