Been trying to grow pumpkins (jack-o-lantern types) for the grandkids for a couple years with limited success. Any tips (direct sow vs pre-start etc.) are welcome, know there are some good growers on the forum. Have a mostly clay soil up here.
Thanks for the information, been doing some of what's provided but clearly not enough. We'll give it another try and see.Go to Holmes seed website. Pick varieties with powdery mildew tolerance. I can personally recommend Superior and Summit.
Plant around the first week of June.
Fertilize with something like 12-12-12 @ 10-15 lbs per 1000 sq ft. Spread around the whole patch, not all close to the hill. You can put 1/2-2/3 at planting and the rest when the vines start to run.
Plant in hills, 3-4 seeds 5-6 feet apart.
Mulch is good.
Spray with something like sevin to control bugs starting about a week after emerging. Watch for aphids, malathion will control them.
Fungicides are tougher in a home garden. Copper and sulphur fungicides are probably your best bet.
If you water avoid wetting leaves, lay the hose on the ground to soak the soil, not the leaves.
