Blueberry Bush is Dying – What to Do
Is your blueberry bush suddenly not looking so good? Are the leaves drooping or are the berries starting to shrivel up as harvesting season gets closer? Here are the most common reasons for dying blueberry bushes. Find out how to revive your plant before it’s too late.
Check the pH level of the Soil
Blueberries are plants that that thrive in acidic soil. An optimal pH level for blueberry bushes is considered to be somewhere between 4.5 and 5.5. If the soil pH is too neutral or alkali then the blueberry bush may not be able to properly absorb essential nutrients like iron.
While it doesn’t happen quickly, there are a number of external factors that can gradually change the pH level of the soil over time. We suggest to check the conditions of the soil and mix in some soil acidifier if the soil has too neutral of a pH.
Too Much Fertilizer
A lot of gardening beginners make the mistake of adding too much fertilizer to the soil. Plants like blueberry bushes can actually get damaged from being over-fertilized. You don’t really need to add fertilizer to the soil as long it is acidic and full of organic matter. For healthy blueberry plants, an annual dressing of compost is usually enough to get the plant going.
The Soil is Too Moist
Watering is typically the number one cause of dying plants. This could come from watering the blueberry bush too much or too little. Blueberry bushes can die from over-watering as the compacted soil will suffocate their roots system.
At most, blueberry bushes only need about 1 to 2 inches of watering per week. If the bush is being grown in a planter or container then make sure the soil inside is draining well. You can add materials like perlite if that isn’t the case.
Pests Attacking Blueberries
There are many pests and wild animals that will love to get their hands on your blueberry bush. To protect your blueberry plant from insects like aphids and Japanese beetles, it may help to use natural remedies like diatomaceous earth to get rid of them. For a sustainable solution, we suggest looking into beneficial insects. Let the bugs do the work for you!
For wild animals like deer and rabbits, you may need to implement a physical barrier like a fence to prevent the animals from reaching your precious blueberry plants. You will know it’s the wild animals that are causing your blueberry bushes to die if you see a lot of holes along the foliage.
