Question 1

Why do I need to fertilize my Highbush blueberry?

Accepted Answer

Regardless of which kind of Highbush blueberry you own, regular fertilization will help you grow a plant that has great overall health. The proper supply of nutrients leads to more vigorous growth and can help your Highbush blueberry be more resilient to tough growing conditions while also gaining a better ability to fight off diseases and pests.

The foliage of your Highbush blueberry is one of its most attractive features, which is why you should do all you can to keep it intact. Again, this means creating and adhering to a regular fertilization schedule that is specific to your Highbush blueberry. Doing so will prompt your Highbush blueberry to develop leaves with a deep color and a lush overall look.

Question 2

When is the best time to fertilize my Highbush blueberry?

Accepted Answer

The first time that you should fertilize your Highbush blueberry is during the late winter or early spring. This type of fertilization gives your Highbush blueberry all the nutrients it needs to resume healthy growth once the weather gets warm enough.

It is also beneficial to many Highbush blueberry to provide an additional fertilizer feeding during early fall if you in a warm climate region. Fertilizing in early fall not only adds additional nutrients to the soil, which your Highbush blueberry will use in the following growing season, but it also helps your Highbush blueberry be a bit more hardy and capable of surviving the winter cold without experiencing foliage damage. Earlier fertilisation will ensure that the new branches have enough time to grow to withstand the cold winter.

Question 3

When should I avoid fertilizing my Highbush blueberry?

Accepted Answer

There are a few times during the year when you should not fertilize your Highbush blueberry. The first time occurs during the early and mid-winter months, during which time your Highbush blueberry will be dormant and in no need of feeding.

It is also unwise to fertilize this plant during the late spring and all of the summer. During that time of year, the weather will likely be hotter and can be much dryer as well. Both conditions make it more likely that your Highbush blueberry will have a very negative response to fertilization. To avoid such issues, stick to a fertilization schedule that involves feeding exclusively during early spring and early fall.

Question 4

What type of fertilizer does my Highbush blueberry need?

Accepted Answer

In most cases, the most important nutrient for a Highbush blueberry is nitrogen, but that does not mean that phosphorus and potassium are unimportant. On the contrary, your Highbush blueberry likely needs a decent amount of all three main nutrients, which is why a balanced fertilizer, such as a 10-10-10, can work well.

However, a more nuanced ratio of nutrients often leads to optimal growth for a Highbush blueberry. Often, fertilizers that are a bit higher in nitrogen work a bit better. For example, a ratio of 10-6-4 can often work well. When fertilizing, you can use a granular fertilizer or a liquid-based one.

Question 5

How do I fertilize my Highbush blueberry?

Accepted Answer

To fertilize your Highbush blueberry using a granular fertilizer, all you need to do is sprinkle the fertilizer on the soil at the correct time. The slow-release nature of granular fertilizer will release nutrients into the soil slowly over time. As is usually the case, it's best to water your Highbush blueberry, at least lightly, before applying fertilizer.

As an alternative, you can use a liquid fertilizer, but this is less common. To use this approach, mix your fertilizer with water, then pour the water onto the soil around the base of your Highbush blueberry. At times, it is beneficial to perform a soil test before fertilizing to see if you will need to alter the pH at all.
