I was going to ask this very same question!
We have a pretty large garden, the horses don't care for much in it. Last year we planted apple trees, carrots, and WATERMELON! They love them and so do we!
Wish they would eat squash, I've always got a plenty of extra.
Watermelon would be nice. I don't think I would be able to grow them though. Ditto to most fruit trees. So I'm stuck with carrots, celery and spinach. Not sure that they would eat spinach but it grows really well here.
I usually plant a cantaloupe plant for my guys. They like the rind and everything. A coworker of mine says that something in the cantaloupe seeds works like a natural dewormer and a half a fruit should be enough to "deworm" an average horse. Not sure about that, but they sure seem to like the flavor!
FURBABY toss some watermelon seeds at the back of your manure pile or make a seperaste pile and watch just how easy it is to grow those suckers as well as pumpkins. Roses tomatoes cucmbers all love that stuff lol
I grow all kinds of vegies and tons of carrots. I toss my horses corn husks and cobs as well as beet tops watermelons dandy lions ( weeds ) I don't grow those lol they just move in. Maragold tops Bananas ( I don't grow those But my horses love them peels and all )
Man I got to stop typing fast lmao I got typos like I got horses lol. Plus this tiny dang thing causes fat finger syndrom lol
Start your corn indoors just use CowPots they are recycled cow manure compressed into starter pots helps in preventing transplanting shock. Most corn only takes between 74 to 80 days so starting them indoors 4 weeks before last frost ( Not sure your area ) I started mine yesterday.
I was going to suggest the same thing with the watermelons!
Normally they don't transplant well, so use the biodegradible peat pots and make sure you acclimate them to the sun before planting. Shouldn't have a problem!
