* **High Nitrogen Needs:** Tomatoes are heavy feeders, requiring a significant amount of nitrogen to produce large, healthy fruits. Nitrogen is crucial for leaf growth and overall plant vigor. * **Phosphorus and Potassium:** While nitrogen is the star, phosphorus and potassium are equally important for tomato plant development. Phosphorus promotes root growth and flowering, while potassium helps with fruit development and overall plant health.

What are some other options?” Emma’s question highlights a common issue: many gardeners struggle to find suitable alternatives to shop-bought fertilisers. This is a significant concern because fertilisers are essential for plant growth and development. They provide essential nutrients that plants need to thrive, and without them, plants can suffer from stunted growth, yellowing leaves, and other problems. However, the reliance on shop-bought fertilisers can be problematic. They often contain synthetic ingredients that can be harmful to the environment and human health. Additionally, they can be expensive, and their effectiveness can vary depending on the type of plant and the soil conditions.
