Is Liquid Seaweed Good for Tomatoes? | How to Get More Tomatoes

Liquid seaweed is a fantastic root tonic that promotes the growth of a range of healthy soil bacteria which helps to release nutrients from the soil in a way that allows the roots to absorb them. Liquid seaweed contains trace elements, minerals and nutrients such as iron, zinc, nitrogen, magnesium and potassium.

Liquid seaweed is a gentle tonic rather than a fertilizer and pairs perfectly with pelleted chicken manure.

This article will explore why liquid seaweed is good for tomatoes, when to add it to your plants and how much to add.

What liquid seaweed does for tomato plants

Liquid seaweed is a natural way to add loads of minerals and nutrients that are captured in the seaweed. Add seaweed has benefits for the roots and stems and helps the plant to grow a strong base for producing fruit and leaves.

Adding liquid seaweed will add small amounts of nitrogen for good leaf growth, potassium for stem and root growth and minerals such as iron, zinc and magnesium.

When to add liquid seaweed to tomatoes

Liquid seaweed is best added to the tomato plants when they are first planted, 4 weeks and then 8 weeks after being planted. This will set the plant up for loads of flower growth and fruit production.

Liquid seaweed is mild enough to add to tomatoes every month. I like to stop adding it however when the flowers appear on the plant. This will allow the nitrogen levels to drop, the phosphorus ratio to increase and for more flowers and fruit to come.

I like to add liquid seaweed to the soil around the tomato plants with a watering can. Keeping moisture off the leaves is best way to prevent fungus and mold growth.

How much liquid seaweed to add to tomatoes

Liquid seaweed is usually sold in concentrated form. It needs to be diluted in water before being added to your tomatoes. The ratio is written on the label but I tend to fill a bucket up with water and add a dash of seaweed. It should look like dirty water but you should still be able to see through it.

Add diluted liquid seaweed to your tomato plants when they are first planted out, 4 weeks later and after another 4 weeks. This will be plenty to give them the best start and then you can stop.

There is no harm in adding more as the tomatoes are growing, however it usually is not necessary unless your soil is very poor. Liquid seaweed will help to improve the soil slowly over time.

If you have very poor soil, add compost, a handful of blood and bone meal and pelleted chicken manure to add extra nitrogen before planting seedlings.

What is the best liquid feed for tomatoes?

Tomatoes will benefit from a liquid fertilizer with more nitrogen at the start of their growth and then higher in phosphorus as they continue to grow.

I like to use a natural liquid fertilizer containing nitrogen to give my tomatoes an extra boost 2 weeks after they have been planted. If you have added pelleted chicken manure to the soil, then you will not need to add extra liquid fertilizer.

If your tomatoes are growing lots of leaves stems and no flowers and fruit then add liquid fertilizer rich in phosphorus. These are usually labeled as a fruit promoting fertilizer or even a tomato fertilizer.

What is the best homemade fertilizer for tomatoes?

The best homemade fertilizer for tomatoes is a mix of homemade compost and aged manures. If you have chickens at home, break down

For a special homemade mix to improve the soil before planting tomatoes, mix 1/2 aged cow manure, ½ a wheelbarrow full of compost, 3 handfuls of pelleted chicken manure and a handful of rock minerals. This will give you a great natural soil improver which will gradually release nutrients for our plants.

Mix it through the soil 4 weeks before planting tomato seedlings to give them the best start.

Follow this up with liquid seaweed fertilizer when you plant them out, and 4 weeks later. You will have amazing tomatoes producing loads of fruit in no time.

How to increase yield on tomatoes

There are a few tips that will help you to get more tomatoes and increase yield on each plant. Check out my top 3 tips for increasing yield on tomatoes

1. Avoid overusing nitrogen

Adding too much nitrogen in the soil can decrease tomato yield. The plant will prioritize leaf growth over fruit production. This means you will get a large healthy, leafy green tomato bush but few tomatoes.

You can fix this problem by applying fruit promoting fertilize which will decrease the ratio of nitrogen to phosphorus, stimulating the plant to go to flower.

Avoid adding too much high nitrogen synthetic fertilizers to your tomato plants and use organic options instead. They will gently release nitrogen at the start then you can stop adding them when the flowers appear.

2. Add a natural root tonic

Add liquid seaweed to tomatoes when you first plant them out, 4 weeks later and then 8 weeks later. This will help the plant to develop a strong root system and stems.

3. Plant them in full sun

Full sun is essential to encourage tomatoes to increase their yield. Full sun or at least 6-8 hours will give you large and sweet tomatoes throughout the summer season.

Is Liquid Seaweed Good for Tomatoes? | Summary

Liquid seaweed is good for setting up tomato plants of a great yield over summer. Liquid seaweed is a mild root tonic which helps to increase the availability of nutrients for the plant. It helps to promote the growth of a range soil bacteria which break down organic matter in the soil making the nutrients available to plants.

Liquid seaweed is natural, full of minerals and a great prebiotic which promotes good soil bacteria populations. Tomatoes love a dose of liquid fertilizer when they are first planted out to get the best start.

Happy growing.
