Puneți asta în pământ înainte de răsărit: trucul care face petuniile și surfiniile să înflorească până toamnă • Newsweek România

Using eggshells can enhance the growth of petunias and surfinias when prepared correctly. Properly processed eggshells provide essential calcium to the soil, promoting healthier plants. The key is to clean, dry, and grind the shells into a fine powder for better nutrient availability. This powder should be lightly mixed into the top layer of soil, serving as a supplement rather than a complete fertilizer. Moderation is crucial to avoid over-fertilization.
