Direct sowing is the method of growing your plants from seed sown right in the garden. Plants that require a long growing season won't perform well when direct-sown in cool-weather regions.

What makes tomato plants grow faster?

Good reserves of phosphorus also are needed for fast-growing tomatoes because that nutrient is responsible for well-developed root systems, which are essential for planting feeding. The third macronutrient, potassium, builds strong stems and wards off diseases, ensuring healthy growth of young tomato plants.

How do you keep a tomato plant short and stocky?

Pruning and Support

Generally if you plant multiple seeds into a hole, if both plants grow out you will have to cut, kill or transplant the secondary (usually weaker) plant.

Why are my tomato seeds not germinating?

During the germination process, a seed needs much more moisture in the soil than when it has sprouted, so be aware and decrease the moisture levels as young seedlings emerge and mature. If soil conditions are too wet, an anaerobic condition can be created and seeds may not be able to germinate due to lack of oxygen.
