Garden Soil

Soil Type

Water: Large cranberry prefers moist, acidic soils, thriving in bog-like conditions. Water every 1-2 weeks to keep soil damp but not waterlogged. Being an evergreen, large cranberry retains foliage year-round, affecting its lower transpiration rates and subsequent watering needs.

Fertilize: For optimal growth of large cranberry, use balanced fertilizers in spring for flowers/fruit and high nitrogen post-harvest. Fertilize twice yearly, adjusting for seasonal changes. Maintain consistently moist soil for nutrient uptake while adhering to label rates to prevent harm from excess fertilization.

Pruning: Large cranberry, valued for its dense evergreen foliage and tart berries, thrives with early spring pruning before new growth. Key techniques involve thinning older stems and trimming dead branches, promoting air circulation, fruit production, and disease prevention for sustained health and yields.

Propagation: Large cranberry thrives in well-drained, acidic soil that resembles its natural bog habitat for successful propagation. Maintaining consistent moisture without overwatering is essential for seed germination, while selecting healthy parent plants enhances seedling strength, ensuring robust growth and fruit production in suitable environments.
