How to Fertilize Blueberry Plants
/2 Comments/in Fruits & Vegetables /by espomaThere’s nothing like fresh-picked blueberries to add to a smoothie, salad or dessert. Rich in many health-benefiting nutrients, anti-oxidants, and vitamins, blueberries don’t just taste delicious, they’re also nutritious.
The secret to grow delicious, thriving blueberry plants: feed them, a lot.
Maximize your blueberry bushes’ health, help it resist insects and diseases, and boost your harvest by providing the right kinds of soil amendments.
When to Fertilize Blueberries
Fertilizing is recommended in early spring before the leaves have grown in. This gives the fertilizer time to be absorbed by the roots of the blueberry before it enters its active growth stage during summer.
Feed new plants once in early spring and again in late spring. Healthy, established plants should not need to be fed more often than once a year.
The Best Fertilizer for Blueberries
Blueberry bushes respond best to acid fertilizers such as those for rhododendrons and azaleas. Holly-tone has long been used by professional gardeners as the best source of food for berries.
From blocking weeds to conserving water, mulching goes hand in hand with fertilizing and is also very important for blueberry bushes. By feeding as it decomposes, mulch helps to maintain soil acidity. The best mulch options are oak leaves, pine straw or pine bark. Gardeners should spread it in a 3-4” thick layer.
How to Fertilize Blueberries
For established plants, spread one cupful of Holly-tone per foot of branch spread. Double the quantity if branch spread is 3’ or larger.
If the area to be fed is mulched, remove as much mulch as you can, feed, and then restore the mulch on top of the plant food. If you can’t remove the mulch, just double recommended feeding rates.
To lower the pH of soils for optimum growth of acid-loving plants such as blueberries, you can also mix in Soil Acidifier as needed.
Always water well after fertilizing.

Sun-kissed, slightly tart blueberries. Sweet, juicy raspberries. Scrumptious strawberries as sweet as candy. Sugary, tart blackberries.
Who can resist such delightful, fresh flavors right from the garden?
Certainly not local birds! Crows, blackbirds, robins, jays and more swoop in and eat your berries right from under you!
If you’re growing blueberries (or any berries!), you want to make sure you get to enjoy them, not the birds. Here are our tips for protecting your berries from those hungry birds — while still being kind.

If you’re growing blueberries, make sure you get to enjoy them, not this sparrow. Here are our tips for protecting your berries from those hungry birds — while still being kind.
Take Back the Patch — How to Protect Fruit from Birds, Naturally and Organically
1. Location, Location, Location. Plant or move berries away from hedges and larger shrubs since birds like to rest there.
2. Take Cover! When your berries are immature, add a row cover or bird netting. Make sure the netting is secure, so the birds can’t undo it. This is, hands down, the best way to protect berries.
3. A Sprinkle of Sparkle. Tie a shiny bird scare tape, or foil tape, around your berry bushes or plants to deter birds. Birds don’t like the movement or the tape’s bright reflection.
4. A Dash of Pepper. Sprinkle cayenne pepper around your berry plants as they begin to ripen. This method is super easy, but makes it hard to enjoy eating berries as you pick! You have to wash off the berries before eating to remove any remaining pepper.
5. Snack Attack! Install a few bird feeders to encourage birds to eat there — and not your berry bushes!
Victory! Now, make sure your blueberries continue to thrive by feeding with Holly-tone. Keep the soil acidic, too, with Espoma’s Organic Soil Acidifier.
