First make sure the ground temp is above 70° F. They will do best in full sun, but they can take a little partial shade. The more sun the better. If you have clay soil, you will need to dig a rather large hole to be filled in with a good compost mixture a week in advance. Plant the seeds (2-3) in a small hill to allow for water runoff. After the plants are established you will need to pay close attention to watering. They are thirsty little guys, but do not like wet feet either. One other thing, if you are limited of space, you can get pumpkin seeds in a bush variety. That's all I got. I've tried them in my yard, but there is not a spot that really gets the required sunlight they need to grow properly. Good luck!
