What Fertiliser Should You Use for Strawberries? 

If you want to grow luscious, sweet strawberries anywhere in Australia, you need to understand their fertiliser requirements.

Primarily, strawberries require a fairly balanced fertiliser that contains adequate amounts of nitrogen, phosphorus, and potassium.

The nitrogen will help the growth of the plants themselves while the phosphorus will promote a healthy root system and the potassium will produce lots of luscious red fruits. Experts also say that a fertiliser that contains plenty of potassium will produce sweeter fruit.

Here are some of the best fertilisers that you can use on your strawberries.

Yates Dynamic Lifter

If you’re growing strawberries in the ground, you really can’t go wrong with Yates Dynamic Lifter. It’s an organic slow-release fertiliser that contains all the necessary nutrients that your strawberries need.

This is the number one fertiliser that I like to use in my garden on all types of different plants, especially fruiting and flowering crops such as strawberries. 

The N:P:K ratio for all-purpose Dynamic Lifter is 3.5:1.0:1.6. This is ideal for fruiting plants such as strawberries. It has the perfect amounts of the major nutrients to grow strong and healthy plants that will produce plenty of fruits.

Dynamic Lifter can be incorporated into your soil before planting out your strawberries or used as a side-dressing in early spring to give your plants a boost throughout the growing season.

This is the product that I use for the strawberries that I grow in pots because it’s also a slow-release product and is extremely easy to apply to the top of the soil.

Its N:P:K ratio is 9.7:2.0:7.0. If you compare it to Dynamic Lifter, you’ll notice that the ratio of phosphorus and potassium to nitrogen is fairly similar. This product will feed the strawberries for up to four months.

Yates Thrive Strawberry & Berry Fruit Liquid Plant Food

For those people that like to liquid feed their plants rather than using pellets, Thrive is a good alternative. It has an N:P:K ratio of 9:2:8 which is absolutely perfect for strawberries and should yield lovely sweet fruits.

Being a liquid feed, this will need to be applied once a week from spring and throughout summer while the plants are actively growing. This is because the nutrients in a water-soluble fertiliser will be used immediately by the plants.

Take extra care not to exceed the dosage recommendations on the pack because the application of too much nitrogen can burn the roots of the plants.

It’s also important, when using this type of fertiliser, to flush the soil at least once a month to avoid a build-up of salts. To do this, just give the pots a good soaking until the excess water drains out of the bottom.

If you’re going to be using a liquid feed on plants growing in the ground, make sure that you give your plants a good soaking with clean water in between fertiliser applications.

Seasol PowerFeed

Another thing that I like to do in my garden, is to give the plants a good tonic over the warmer growing month. My go-to favourite for this is usually liquid seaweed like Seasol or Maxicrop.

Standard liquid seaweed like Seasol doesn’t contain a lot of the macronutrients, however, it does contain trace elements and is a really good soil conditioner that helps roots to take up nutrients more easily.

However, Seasol PowerFeed is a relatively balanced fertiliser that has all the benefits of liquid seaweed with added nutrients to also feed your plants. The N:P:K ratio in PowerFeed is 12:1.4:7.

Although this ratio is ideal for strawberries, you’ll notice that the percentage of nitrogen is quite high. Therefore, I would dilute this down to half-strength when using it on my strawberries. This should give the plants all the nutrients that they need without having to add any other forms of fertiliser.

It’s also one of the best products for strawberries that are grown in pots because it’s natural and won’t leave salt deposits in the potting mix that will have to be flushed out.
