If you're looking to grow pumpkins, the soil you will plant them in must be warm and filled with nutrients. Pumpkins can be greedy, so they require full sunlight, compost and a lot of nitrogen along with a weekly dose of 1 inch of water. If you're going to grow your pumpkins in Houston, it is best to sow the seeds in July.
Pests are common in the pumpkin plant. Aphids and beetles can infest your plant, a good way to get rid of the pests with out using a pesticide is to buy reflective mulch (the aphids hate that) or to introduce predatory species to your garden. Ladybugs prey on aphids, if you are using this method, make sure to provide an adequate environment for the ladybugs.
