Those who are in warm-weather zones or got an early start on their pumpkins indoors or in greenhouses are fast approaching first harvest. Unfortunately, picking pumpkins too early means the fruit will be immature, won’t store well and may be very “off” as far as flavor goes. Here’s the lowdown on when and how to harvest the fruits of your labor.
Many pumpkin varieties will be uniform in color when mature. However, this is not true of every variety, so check yours to see how deep the color should be and whether it will be uniform, striped or speckled and/or partially green.Check the Size
Different varieties will grow to different approximate sizes. Note that you may get some fruits that do NOT achieve the expected full size (for a variety of reasons, some fruits simply do not grow to their full capacity) but may still be mature and usable. If you have a smaller-than-expected pumpkin that nevertheless shows other signs of maturity (such as rind hardness and color), it may still be usable provided it has not rotted or been exposed to disease via bruising or cuts.Test the Hardness of the Rind
A mature pumpkin rind (the outer “skin”) is hard and resists denting when a fingernail is pressed into the shell. Be careful – don’t dig deep. Actually cutting into your pumpkin with your fingernail means you will not be able to store it, and leaving it damaged while still growing on the vine exposes the fruit to rot and plant disease.
A light freeze will not damage the fruit (though it will turn the vines brown, a natural occurrence in the life cycle of the pumpkin plant), but a hard freeze will harm your pumpkins. If cold weather and a hard freeze are imminent, cut away as many usable fruits as you can. Fruits that are not quite mature by this time can still be cut up and placed into your compost pile or, in some cases, pickled or stewed.
When cutting your pumpkins from the vine, BE CAREFUL. Do not bruise, scratch or scrape the fruit. If you do, you will not be able to store the fruit. It may rot and if near other pumpkins, could spread rotting to them as well. If you accidentally damage a pumpkin when harvesting, use it immediately, or discard or place in your compost pile (remove the seeds first).Leave a Stem
Never cut the stem too close to the fruit. Leave 3-4″ of stem if possible. NEVER pick up a pumpkin by the stem, even if the stem is thick and the fruit is small and lightweight.Use Pruning Shear
Shears leave a clean cut and reduce the possibility of accidentally cutting into the fruit.
Pumpkins must be cured before storing in order to develop a good, protective rind. If possible, leave your pumpkins for approximately 10 days before storing, at a temperature of at least 70-80F.Store in a Cool, Dry Area
Pumpkins will last the longest if you store them in a cool area, such as a dry, cool cellar. 55F is ideal; make sure the storage area never gets above 65F.Don’t Store Your Pumpkins Near Ripening Fruit
As fruit ripens, it releases an ethylene gas which will ruin your pumpkins. Do not store your pumpkins near ripening apples, pears and so on.Don’t Allow the Fruits to Touch
Leave a bit of space between each pumpkin, and NEVER pile your pumpkins to store them.Go Pumpkin Picking
Periodically, go through your storage and pick out any decaying fruits. Discard immediately. With proper storage techniques, your pumpkins should remain fresh and usable for up to three months.

As home gardeners, there is a tendency to focus on the plants and practices in our own yards and on our own tables. But as you probably already know, there's so much more to gardening. Example: our readers often ask, "What's the difference between organic and conventional gardening?" It can be a confusing subject, especially as different organizations, different farms, and different gardeners may have very different definitions. Let's break things down when it comes to organic vs. conventional gardening.
