How to Plant Tristar Strawberries for Extended Harvests

Overview

Developed at the University of Maryland, Tristar strawberries are popular for their long bearing season. Expect mid-summer bloom after planting, then an early, heavy spring crop in year two. Hardy to USDA zone 2 (with winter cover); zones 9–11 may need annual treatment due to heat. Disease-resistant and day-neutral (unaffected by day length).

Planting Steps

Step 1: Full Sun Location

Choose a site with all-day sun for best quality.

Step 2: Test Soil pH

Target pH 5.8–6.5. Use home kit or county extension service.

Step 3: Hydrate Roots

Remove plants from pots; place in water covering roots.

Step 4: Prepare Bed

Till 2 inches deep, breaking clods and removing debris.

Step 5: Amend Soil

Add 2 inches compost, 1 inch sand, and any pH-specific amendments. Mix well.

Step 6: Mound and Plant

Build 1-foot-apart mounds. Set plant on top, fan roots around, barely cover roots. Keep crown (short stem between roots and leaves) exposed.

Step 7: Mulch Well

Mulch around mounds to warm soil and prevent erosion when watering.

Step 8: Water Consistently

Water well initially, then 1 inch per week.
