Watering: The Delicate Balance

Over-watering is a common mistake that can lead to root rot, nutrient deficiencies, and plant death. Conversely, under-watering can cause stress, stunted growth, and decreased productivity. To water your plants effectively:

• Check the soil moisture by inserting your finger into the soil up to the first knuckle.
• Water plants when the top 1-2 inches of soil feel dry to the touch.
• Use room-temperature water to prevent shocking the roots.
• Avoid getting water on the leaves to prevent fungal diseases.

Nutrition: Fertilization and Soil Quality

Plants require essential nutrients like nitrogen, phosphorus, and potassium to grow and thrive. Fertilization and soil quality play a critical role in providing these nutrients. Here are some evidence-based tips:

• Use a balanced, water-soluble fertilizer (20-20-20) during the growing season (spring-fall).
• Avoid over-fertilizing, as this can cause more harm than good.
• Choose a high-quality potting soil that drains excess water and provides aeration.
• Repot your plants every 1-2 years to refresh the soil and provide a larger pot if necessary.
