Mini Paulista Summer Squash: Growing Guide for Kansas

Mini Paulista looks like a little striped butternut, but the way to enjoy it is to pick it young. Its ivory-and-green fruit is a useful change of pace if you want summer squash and have had trouble with squash vine borers. The plant is Cucurbita moschata, a species with better vine borer tolerance than typical zucchini. Resistance does not eliminate pest risk, and it still deserves a walk through the patch every few days.

Start with warmth

Wait until frost danger has passed and the soil is warm. In central Kansas, early May is a traditional start, but let the weather decide. Direct sow 1 inch deep in full sun and well-drained soil, water gently, then keep the seedbed evenly moist until sprouts appear. If you start indoors, use a biodegradable pot and transplant while the seedling is young so the roots are disturbed as little as possible.

Give the vines room

Thin to a healthy plant about 2 to 3 feet from the next one, with rows at least 3 feet apart. Mini Paulista can begin relatively compact and then run as the season continues, so leave an extra edge or a sturdy trellis if your bed is tight. A trellis may need support for larger fruit. Mulch after the soil warms, water at the base, and aim for steady moisture instead of a late flood after drought.

Flowers, pollination, and picking

Squash makes separate male and female flowers, and pollinators move pollen between them. It is normal to see male blossoms before the first female flowers. Once fruit sets, check often. For the tender summer-squash use, cut Mini Paulista when fruit is about 6 inches long or smaller. Leaving fruit to grow large changes its texture and slows the rhythm of fresh picking. A listed maturity of about 70 days is a planning estimate, not a promise that every young fruit waits that long.

Keep an eye on pests

The tougher stems of moschata squash make Mini Paulista a vine borer resistant option, but still check the base of the vines for eggs, frass, and sudden wilting, and scout for squash bugs too. Kansas State's squash vine borer guide explains identification and management. Rotate squash and other cucurbits to another bed where possible; the Kansas Garden Guide recommends 3 to 4 years between cucurbits in the same space.

After harvest

Handle the young fruit as a fresh summer squash. Refrigerate it and cook it soon; don't assume an immature fruit will store like a mature winter squash. Slice and sauté, grill, or roast it with a little oil and salt so its mild flavor comes through.
