Why Tomato Tips Turn Black

While there are various tomato varieties, each differing in shape, color, and taste, they share a common issue: the blackening at their tops. The primary culprit is a calcium deficiency in the soil. This lack of calcium, crucial for fruit formation, leads to necrosis at the bottom (or top) of the fruit and internal rot, rendering the tomato inedible.

So, it’s not just about water scarcity. For robust growth, tomatoes need to absorb calcium from well-fertilized soil. The roots play a crucial role in absorbing this and other nutrients.

Overwatering or underwatering can impact this process:

• Excessive watering can drown the roots, hindering nutrient absorption.
• Insufficient watering stunts root growth, affecting nutrient and calcium uptake.

Thus, improper calcium absorption, influenced by watering practices, is the real reason for the blackening of tomato tips.
