Provide 1-2 inches of water per week, increasing to 2-3 inches during fruit development to prevent small, dry berries. Avoid overhead watering to reduce fungal disease risk; use drip irrigation or water at the base of plants, ensuring soil stays consistently moist but not waterlogged.

Grow in full sun, requiring a minimum of 6-8 hours of direct, unfiltered sunlight daily to produce abundant flower buds and sweet, well-ripened fruit. Plants grown in partial shade will have reduced yields, smaller fruit, and higher susceptibility to foliar diseases.

Plant in well-draining, loamy soil with a pH between 5.5 and 6.8, amended with compost or well-rotted manure to boost organic matter content. Avoid heavy, compacted clay soils or areas prone to standing water, as this causes root rot and stunts plant growth.

Apply a balanced, slow-release 10-10-10 fertilizer in early spring before new growth emerges, at a rate of 1 pound per 100 square feet of planting area. Avoid fertilizing during the fruiting period, as excess nitrogen promotes leafy growth over fruit production; apply a light topdress of compost after harvest to support runner development.

Thrive in cool spring temperatures between 60-80°F (15-27°C) during the fruiting period, and require 200-300 chill hours below 45°F (7°C) in winter to initiate flower buds. Plants are hardy to USDA zones 3-8, and benefit from a 2-3 inch layer of straw mulch in winter to protect roots from frost heave and extreme cold.

Remove all flower buds in the first growing season after planting to allow plants to establish strong root systems, rather than diverting energy to fruit production. After harvest, mow foliage back to 1-2 inches above the crown, remove excess runners to leave 4-6 inches of space between plants, and thin out old, unproductive crowns every 3-4 years to maintain high yields.

Easily propagated via rooted runners produced by mature plants after the fruiting season; peg runner tips into small pots of potting soil while still attached to the mother plant, then sever once roots have formed after 2-3 weeks. Start new plants from certified disease-free nursery stock every 3-4 years to avoid virus buildup and declining productivity in established patches.

Tolerate average outdoor humidity levels between 40-70%, but require good air circulation around foliage to prevent fungal diseases like powdery mildew and botrytis fruit rot during periods of high humidity. Avoid overcrowding plants and remove dead or diseased leaves regularly to improve airflow.

When grown in containers, repot every 2-3 years in early spring, using a fresh, well-draining potting mix formulated for fruiting plants. Choose a container at least 12 inches deep with drainage holes, and trim back overgrown roots before replanting to encourage new, healthy root growth. For in-ground patches, replace entire plantings every 3-4 years in a new location to avoid soilborne disease buildup.
