Preparing the Soil

Before planting your tomatoes, it’s essential to prepare the soil. Tomatoes require well-drained soil that is rich in organic matter. To improve the quality of your soil, add compost, peat moss, or aged manure to the planting area. Additionally, it’s essential to make sure that the soil’s pH level is between 6.0-6.8.

Tomatoes require consistent watering, at least 1-2 inches of water per week, and regular fertilizing. Additionally, it’s crucial to keep your tomato plants free from pests and diseases. You can prevent diseases by planting disease-resistant tomato varieties and ensuring adequate spacing between plants to allow for good air circulation.

Harvesting Your Tomatoes

When your tomato plants start to produce fruit, it’s essential to harvest the fruit at the right time. To determine when to harvest your tomatoes, observe the fruit’s color and feel.
