My luck with Watermelons is intermittent , I have in a long past now grown a Black Diamond to about 25 pds an 18 pound Triple Crown Hybrid ,
I came close with sangria and Orangeglo that I have growing now , year before last and orange melon was growing nice and something ate a hole through it from side to side ,,
A few Moon & Stars have made 12 or 15 pds ,
I might look for those Schochler seeds ,, limited Growing space ,,
