Tomatoes are among the easiest garden vegetables to grow. You don’t need a lot of prior knowledge to get going. Their sweet, juicy, aromatic flesh makes them one of the favourites among hobby gardeners and people looking to start their own vegetable patch. Even though they’re relatively hardy plants, they require good soil, adequate watering and the right fertiliser to grow. It’s the fertiliser – the plant food – that can make all the difference between poor or healthy growth. But do you know how often to fertilise tomatoes? We’ve collected the best tips for you to ensure you get to enjoy a healthy harvest. 

What type of fertiliser should you use?

Fertiliser is the secret ingredient to healthy tomatoes. But which type you’re going to use depends on the soil you’ve got in place. Balanced soil that contains enough nitrogen and phosphorous is an important prerequisite for strong growth. You can get your soil tested to ensure you’ve got enough of both. If you can’t get a soil test done, a good way to assess soil balance is by monitoring plant growth. Where plants turn sickly despite adequate watering and sun exposure, something isn’t right with the soil.

 

When you’re shopping for fertiliser for tomatoes, you will be able to choose between organic and synthetic options. As the name suggests, the organic fertiliser is made from natural products like compost. It’s best to look for a fertiliser that contains: phosphorus, nitrogen and potassium. Phosphorus stimulates root growth while nitrogen is important for the leaves and potassium promotes faster growth. You can also make your own fertiliser from manure and compost.

When to fertilise tomatoes?

Tomatoes are heavy feeders so they need fertilisation in order to keep growing. If you don’t add nutrients, over time, your plants will produce fewer tomatoes.

 

The best time to fertilise tomatoes is at planting. This way, you’re giving the tomatoes the right start.

 

Once your plant bears fruits, you should re-fertilise the soil. You could even add a little plant food every two weeks to ensure that the tomatoes keep growing. But don’t add too much as over-fertilisation could damage the plants. By monitoring the growth of your plant, you can usually keep an eye on when they may need a little boost. 

How to fertilise tomatoes?

During the planting stage, mix the fertiliser with the soil inside the planting hole. You can cover it with a little raw soil before setting the plant. Make sure you spread out the fertiliser properly because the raw chemicals can burn the roots of your plants.

 

By adding organic matter like compost and manure you will improve the drainage.

 

Aside from providing your plants with adequate nutrients, you should also make sure that they’re being watered regularly. Tomato plants need around one to two inches of water weekly.
