Best Fertilizer for Blueberries

Producing Juicy and colorful berries can be hard work, especially when it comes to blueberries.

Using the right fertilizers and foods for your blueberries will help to improve their colors, fruits, and growth.

In this article, we take a look at some of the best fertilizers for blueberries that are specifically suited to them.


When Should Your Fertilize Blueberries

When fertilizing blueberries, fertilize them, and how much is almost just as important as the fertilizer you are using.

Blueberries and blackberries generally have different needs in fertilization.
The timing of fertilization is based on the growth of the blueberry plant. Blueberries usually respond well to being fertilized three times at separate applications.

In spring, when new growth begins, they need to be fertilized first, then again six weeks later, and lastly, just after being harvested.


What to use and How Much

You will need to get the right fertilizer and know exactly how much of it to use on your blueberries;

  • Fertilizer Type – Blueberries require small amounts of nitrogen to support their root and shoot growth and for healthy foliage and fruits. They need a slow-release nitrogen source to prevent loss through water leaching. They need smaller amounts of Phosphorus and potassium. Generally, fertilizers that work well for azaleas and rhododendrons also work for blueberries as blueberries require more acidic conditions.
  • Applying Fertilizer – Blueberries take up nutrients through their root. Therefore the fertilizer needs to be raked into the soil around the plant without touching the stems. You only need to loosen the surface soil to fertilize and sprinkle a small amount. Work the fertilizer into the soil and water the soil for absorption.
  • How Much Fertilizer Should You Use – Stay clear of excess nitrogen for blueberries as it can actually kill them. You will also need to lessen the amounts for younger blueberries. It is always advised to follow the instructions on the package. Different amounts of fertilizer are stipulated for the different ages and stages of your blueberries’ growth. Keep in mind to keep the ph levels of the soil for Blueberries more acidic as they prefer this.

Features of a Good Fertilizer for Blueberries

Blueberries generally like more acidic soil, and for this reason, you will need high acid fertilizers.

Here are a few tips on choosing the best fertilizers for your blueberries;

Down to Earth

  • Get the Soil to a More Acidic PH – Look for Fertilizers that contain ammonium sulfate or Sulphur Coated Urea. These have a lower PH levels and high acidic levels.
  • High Nitrogen Levels – You will need a fertilizer with High nitrogen, but very high levels of nitrogen generally for blueberries. Ye,t, at all cost,s avoid fertilizers that contain nitrates such as calcium nitrate or calcium chloride. Nitrates can kill some blueberry plant species.
  • Magnesium and Iron – Blueberries are many times susceptible to magnesium deficiency. Therefore, you may need to supplement the fertilizer with magnesium. If your blueberry leaves turn a reddish color on the leaves, particularly towards the leaves’ edges, magnesium deficiency is most likely.
  • Natural Fertilizers – There are some natural fertilizer alternatives that you can use for your blueberries.

Fish Meal or Blood meal can be used for Nitrogen, while sphagnum peat will provide acidity, and bone meal and powdered seaweed will ensure enough potassium and phosphorus. While organic Fertilizers may make fertilizing your blueberries slightly more tedious, they will help keep the soil at the best PH levels and make sure that the nutrient mixes are up to standard.
