My Buying Guide on ‘Best Calcium Fertilizer For Tomatoes’

As a passionate gardener and tomato lover, I understand the importance of providing the right nutrients to my plants. When it comes to growing delicious and healthy tomatoes, calcium is an essential element that cannot be overlooked. Lack of calcium can lead to various common tomato problems such as blossom end rot and stunted growth. That’s why choosing the best calcium fertilizer for tomatoes is crucial for a successful harvest. In this buying guide, I will share my personal experience and tips on how to choose the perfect calcium fertilizer for your tomatoes.

Understanding Calcium and its Role in Tomato Growth

Calcium is one of the primary macronutrients required by plants for healthy growth. It helps in strengthening cell walls, promoting root development, and improving overall plant vigor. In tomatoes, calcium plays a vital role in preventing diseases like blossom end rot, which can cause dark spots on the bottom of the fruit.

Types of Calcium Fertilizers

There are various types of calcium fertilizers available in the market, but not all are suitable for tomatoes. Some common forms include:

1. Calcium Nitrate: This water-soluble fertilizer contains 15.5% nitrogen and 19% calcium. It is quickly absorbed by plants and is ideal for treating calcium deficiency in tomatoes.

2. Gypsum: Made from a naturally occurring mineral, gypsum is a slow-release source of calcium that also improves soil structure.

3. Bone Meal: This organic fertilizer contains about 10% calcium along with other essential nutrients like phosphorus and nitrogen.

Factors to Consider Before Buying

To ensure that you choose the best calcium fertilizer for your tomatoes, here are some essential factors you should consider:

1. Calcium Content: The percentage of calcium present in the fertilizer should be at least 20%.

2. Nutrient Balance: Along with calcium, make sure the fertilizer also contains other essential nutrients like nitrogen, phosphorus, and potassium.

3. Water Solubility: For quick absorption by plants, opt for water-soluble fertilizers as they are readily available to be taken up by roots.

4. Formulation: Choose a formulation that suits your gardening needs- liquid or granular.

My Top Picks

After years of experimenting with different fertilizers, here are my top picks for the best calcium fertilizers for tomatoes:

1. Espoma Tomato-tone Plant Food: This organic fertilizer has an NPK ratio of 3-4-6 along with 8% calcium and is specially formulated for tomato plants.
