Growing Tips for Bern

Soil Care is Essential

Radishes and carrots prefer humus-rich, well-draining, and loose soil. Consistent moisture is crucial to prevent woody or fuzzy roots.

Warmth and Light for Heavy Feeders

Plants like tomatoes, peppers, and pumpkins love sunny, warm, and sheltered spots. Ensure they get enough light and warmth, especially during fruit development, to achieve abundant harvests.

Consistent Water and Nutrient Supply

Broccoli and potatoes are heavy feeders and require a constant supply of water and nutrients. Keep the soil consistently moist, but avoid waterlogging to promote healthy growth.
