Strawberries are temperate crops that perform best when daytime temperatures stay between 18°C and 24°C. While the plants themselves are relatively hardy, the blossoms are extremely frost-sensitive and can be destroyed by temperatures just below 0°C. They require a period of chilling during dormancy to ensure vigorous growth in the spring, but excessive heat (above 30°C) during the fruiting stage causes the berries to soften, stay small, and lose their flavor profile.

This crop performs best in moderate relative humidity, ideally between 60% and 75%. Maintaining this range is a delicate balance; while humidity supports the plant’s lush foliage, high stagnant humidity (above 85%) is the primary driver for Botrytis (Grey Mold), a fungus that can rapidly rot the fruit before or after harvest. Good air circulation and the use of raised beds or plastic mulch are essential to keep the berries off the damp soil and allow the canopy to dry quickly.

The ideal soil is a rich, well-drained sandy loam that can accommodate the plant’s shallow and highly sensitive root system. Strawberries are “heavy feeders” that require high levels of organic matter to support their rapid fruiting cycles. They are notoriously intolerant of waterlogged conditions, which lead to root rot (Phytophthora), yet because their roots are so shallow, they require frequent, light irrigation to prevent moisture stress.

For optimal growth and fruit quality, maintain a slightly acidic pH between 5.5 and 6.5. Within this range, the plant can effectively absorb the phosphorus and micronutrients necessary for berry development. If the soil becomes too alkaline (above 7.0), strawberries often suffer from iron chlorosis, resulting in yellowing leaves and a significant decline in overall plant vigor and yield.
