4 Reasons Why Your Blueberry Bush Flowers but Doesn’t Fruit

Blueberry Bushes

Have you been looking forward to harvesting some tasty blueberries only to find that the bushes aren’t producing any fruit? What could cause a blueberry plant to flower but not produce a single fruit? Here are the most common reasons and ways you can prevent this situation in the future.

Plant isn’t Mature Yet

The simple reason could be that the blueberry plant is not mature yet. Some people who are new to growing blueberries expect to be able to harvest in the first year they are growing the plants. Unfortunately, that isn’t necessarily the case. Blueberry bushes may take anywhere between two to four years to mature and be able to produce any fruit. In this case, you will just have to be patient until the plant is ready.

One simple way to determine the age of a blueberry plant is by observing the color of its stem. New blueberry bushes tend to reddish stems. Older plants tend to have stems that are more brown and grey.

Pot Size is to Too Small

Are you growing the blueberries in containers? One other common reason that prevents blueberry bush from producing fruit is due to the pot being too small, which doesn’t offer an optimal environment for blueberry plants. You will know when the plant is outgrowing its container when roots start to appear above the soil and also starts to block the drainage holes underneath.

So what’s a good pot size for a blueberry bush? As a starting point, we recommend looking for a pot that has a depth of at least 24 inches and a width of about 30 inches.

The Plants Aren’t Getting Full Sun

In order for blueberry bushes to produce fruits, it’s essential for them to be grown in full sun conditions. This pretty much applies to any other fruits and vegetables. For the next harvesting season, make sure the plants are placed in a location where they can receive at least six to eight hours of full sunlight per day.

You Haven’t Been Pruning

Blueberry bushes may also produce very little fruit if they are investing all their energy in other places. For example, it’s important that old canes and stems are pruned each spring in order to encourage new ones to grow. Cutting away the oldest and thickest canes will encourage new canes to grow from the roots.
