Before planting, you need to prepare your garden and purchase good-quality seeds and soil from a trusted company. You can plant seeds directly into the ground or purchase seedlings.

Preparing the soil

Ensure that your soil is well prepared with organic matter and nutrients such as phosphorus, calcium, and nitrogen. You can add them in different ways, such as fertilizers and compost. Make sure you follow package directions when adding any type of fertilizer or composted material.

Tomatoes require a lot of nutrients, especially during the early stages. They like soils that are rich in organic matter as this will keep them healthy as they grow. You can add aged compost, rotted manure, or vermicompost to improve the fertility of your soil. You’ll also need to remove all weeds from your garden before you start planting tomatoes. Pull the weeds out by hand.

Planting

Once you have added composted material to the soil, you can plant your tomato seeds or seedlings. Plant them at a distance of 8 to 12 inches between plants and 18 to 24 inches from rows. You’ll need to water the seeds or seedlings after planting.

Keep the soil damp but not soaked as this will lead to disease and root rot. You can water the plants with a drip irrigation system if you want for this purpose. To protect young tomato plants from birds and pests, cover them with screen netting.

If you live in the northern part of the state, where winters tend to be cold, then planting them during spring is ideal.
