When to Plant Kiwi in Howard County, TX
Kiwi vines produce fuzzy, tangy-sweet fruits and need both male and female plants for pollination. Hardy kiwi varieties (A. arguta) are suited to colder climates.
Howard County, Texas is in USDA Zone 7b. The average last spring frost is March 26 and the first fall frost is November 12, giving you a growing season of approximately 231 days.
At an elevation of 3,918 feet, Howard County receives approximately 59.3 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 99°F, so Kiwi may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Kiwi will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Kiwi root diseases.

Kiwi Heat Requirements (GDD)
What are Growing Degree Days (GDD)?
Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.
Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.
