Fall Gardening in Kansas: Harvest, Curing and Seed Saving
By Autumn Prairie Pumpkins
Fall is the payoff season on the Kansas prairie. The wind turns, the vines slow down, and everything you did back in May finally sits on the porch in orange and tan. Here is how we close out the season at our Newton, Kansas homestead, and how to set yourself up for an even better spring.
When to Harvest Pumpkins in Kansas
Most Kansas pumpkins and winter squash come ready between mid-September and mid-October. Don't go by the calendar alone. A fruit is ready when the rind resists a fingernail, the stem has hardened and started to dry, and the color is deep and even. Around Newton our first fall frost usually lands in mid to late October, so plan to have everything off the vine before then. A light frost won't ruin a mature fruit, but a hard freeze will shorten its storage life fast.
Cut, never pull. Leave 2 to 4 inches of stem as a handle you never use, a snapped stem is an open door for rot.
Curing: The Step Most Gardeners Skip
Curing hardens the rind and heals small nicks so your harvest keeps through winter. Give pumpkins and squash 10 to 14 days somewhere warm, around 80 to 85 degrees, with good airflow. A sunny porch or a shed that still holds afternoon heat works fine in a Kansas September. Moschata varieties like Seminole and Long Island Cheese also get sweeter after a few weeks of storage, patience pays in pie.
Save Seeds From Your Best Fruit
Fall is seed-saving season. Pick your healthiest, most true-to-type fruit from open-pollinated varieties, scoop the seeds, rinse the pulp away, and dry them on a screen for two to three weeks. Remember that squash cross-pollinates readily, so unless you isolated or hand-pollinated blossoms, saved seed from a garden with several varieties may surprise you next year. That surprise can be fun, but if you want the real thing, save from hand-pollinated fruit or start fresh with true seed.
Plant Now for Next Year
- Garlic goes in the ground in October in Kansas, it wants the cold winter to bulb properly.
- Cover crops like cereal rye or crimson clover sown in September and October protect your soil all winter and feed it in spring. Strong soil builds strong plants, and fall is when next year's soil gets built.
- Clean up vine borer habitat. Pull and destroy spent squash vines instead of composting them, vine borer larvae overwinter in the soil and debris. K-State's squash vine borer guide covers the full life cycle.
