New Post - What to Grow In the September Organic Garden
Blueberries are one of those fruits that seem like they should be difficult to grow, but once you give them the conditions they need, they can be surprisingly easy.
The biggest thing to remember is this: Blueberries need acidic soil. And I mean properly acidic soil!
Unlike many of the fruits and vegetables we grow in the Organic Yarden, blueberries don't want ordinary garden soil. They naturally grow in acidic conditions, so getting the soil right is the most important part of growing them successfully.
The good news is that blueberries are perfectly suited to growing in containers, which makes them a fantastic choice if your garden soil isn't naturally acidic.
And those little blue berries are definitely worth growing.
There are lots of reasons to grow your own blueberries.
They're:
Delicious eaten straight from the plant
Easy to grow once established
Perennial
Perfect for containers
Suitable for small gardens
Attractive garden plants
Great for pollinators
Packed with flavour
Wonderful for vegan recipes and breakfasts
And there's something rather lovely about wandering into the garden and picking a handful of blueberries for your breakfast.
Although you may need to get there before the birds do!
Blueberries like a sunny, sheltered position.
Choose somewhere that gets plenty of sunlight, ideally around 6 hours or more of direct sun a day.
They can tolerate some light shade, but you'll generally get the best flowering and fruit production in a sunny position.
Blueberries can be grown:
In the ground
In raised beds with suitable acidic soil
In large pots which is how I grow them
In containers
On patios and terraces
If you have alkaline or neutral garden soil, growing blueberries in containers is often the easiest option because you can control the growing medium.
If you remember nothing else from this guide, remember this:
Blueberries need acidic growing conditions.
They generally prefer a soil pH of around 4.5–5.5.
This is considerably more acidic than the soil preferred by most vegetables.
If your soil isn't acidic enough, your blueberry plant may struggle to take up nutrients even if those nutrients are present in the soil.
You may notice:
Pale or yellowing leaves
Poor growth
Reduced fruit production
Before planting blueberries directly into the ground, it is worth checking your soil pH.
A simple soil pH test can save you a lot of frustration later.
If your garden soil isn't naturally acidic, containers are your friend.
Use a large container with good drainage and a suitable ericaceous, acidic compost.
Avoid ordinary multipurpose compost if it isn't suitable for acid-loving plants.
Choose a container that gives the roots plenty of room to grow and make sure it has drainage holes.
Blueberries don't like sitting in permanently waterlogged compost.
Growing them in containers also means you can keep a much closer eye on the growing conditions.
If you're planting more than one blueberry bush, give them plenty of space to grow.
For smaller varieties, around 1–1.5 metres apart can work well.
Larger bushes may need more room.
Always check the mature size of the particular variety you are growing before deciding on your final spacing.
Remember — that tiny plant in the garden centre isn't going to stay tiny forever!
Choose an acidic, well-drained growing position.
If planting in a container:
Choose a large container with drainage holes.
Fill it with suitable ericaceous compost.
Gently remove the blueberry plant from its pot.
Tease out any tightly packed roots if necessary.
Position the plant at approximately the same depth it was growing previously.
Fill around the roots with your acidic compost.
Gently firm the compost.
Water thoroughly.
Avoid planting too deeply.
Blueberries have relatively shallow root systems, so take care not to disturb their roots unnecessarily.
Blueberries need consistent moisture, particularly while they are establishing and when the fruit is developing.
But there is an important balance:
Moist soil — not a blueberry swimming pool!
Rainwater is particularly useful for blueberries because it doesn't contain the same levels of dissolved minerals found in some mains water.
If you can collect rainwater in your garden, it is an excellent choice for watering acid-loving plants.
During dry weather, check container-grown blueberries regularly because pots can dry out surprisingly quickly.
If you already collect rainwater, your blueberries will appreciate it.
Blueberries prefer acidic conditions, and rainwater is generally softer than mains water.
In areas where mains water is hard, regular watering with it can gradually affect the growing conditions around acid-loving plants.
So if you've got a water butt...your blueberries have just found their favourite watering can!
Blueberries don't need huge amounts of fertiliser. The most important thing is maintaining the correct acidic growing conditions. Use a suitable organic feed designed for acid-loving plants if your blueberries need additional nutrients.
Avoid using lime or other products intended to raise soil pH around blueberries.
That would be rather like inviting your blueberry to dinner and serving it something it specifically asked you not to bring
A layer of suitable organic mulch can help maintain moisture and protect the shallow root system.
Good options can include suitable acidic organic materials such as:
Pine bark
Pine needles
Leaf mould made from suitable leaves
Other mulch recommended for acid-loving plants
Keep mulch away from the immediate base of the stem.
Mulching also helps suppress weeds, which is particularly useful because blueberries don't appreciate too much competition around their shallow roots.
Some blueberry varieties are self-fertile, so you can grow a single bush and still get fruit.
However, growing two or more compatible varieties can improve pollination and potentially give you a better crop. We actually grow four plants as we love Blueberries.
Different varieties can also fruit at different times, which means you can extend your blueberry harvest.
When choosing plants, check their flowering and fruiting periods and select varieties that are compatible.
Before you get those delicious blue berries, you'll get flowers.
Blueberry flowers are attractive to bees and other pollinating insects.
Encouraging pollinators into your garden is an important part of organic gardening.
Growing blueberries alongside other pollinator-friendly plants can help create a garden that provides food for insects throughout the growing season.
And of course, the bees help us get those berries!
The exact timing depends on the variety and growing conditions, but blueberries generally fruit during the summer months.
Young plants may produce only a small crop initially.
Don't be disappointed if your first harvest isn't enormous.
Like many perennial fruit plants, blueberries need time to establish.
A healthy, mature bush can reward you with a much larger crop.
Let's just say that birds know exactly when blueberries are ripe.
And apparently they don't believe in asking permission.
If birds are helping themselves to your crop, cover the bushes with suitable bird netting or another safe physical barrier.
Make sure any netting is properly secured and doesn't create a danger for wildlife.
Protecting the crop is particularly important as the berries begin to ripen.
Blueberries don't need aggressive pruning when they are young.
Once established, pruning helps maintain a healthy, productive bush.
The aim is to encourage a mixture of younger and older stems and remove:
Dead wood
Damaged branches
Weak growth
Overcrowded stems
Very old, unproductive wood
The exact pruning approach can vary depending on the age and variety of your blueberry bush.
Don't reach for the secateurs just because you've found them, either.
Pruning for the sake of pruning is not a gardening qualification.
This is the fun bit. Blueberries are ready to harvest when they have developed their full colour and come away from the plant easily. Ripe berries should be sweet and juicy.
Try to pick them regularly once they start ripening because leaving ripe berries on the bush gives birds plenty of opportunity to discover your breakfast.
You can eat them fresh, freeze them or use them in all sorts of recipes.
Fresh blueberries are fantastic in:
Porridge
Overnight oats
Smoothies
Pancakes
Muffins
Crumbles
Cakes
Chia puddings
Homemade jam
Desserts
And, of course, they're pretty hard to beat eaten straight from the bush.
Check your plants for new growth.
Mulch if needed.
Feed with a suitable acid-loving plant feed if required.
Keep plants watered during dry spells.
Look out for the first flowers.
Keep plants consistently watered.
Watch the developing fruit.
Protect berries from birds.
Harvest ripe blueberries regularly.
Continue watering during dry periods.
Enjoy the colour of the leaves, they are gorgeous
Remove fallen or damaged material around plants.
Check containers and drainage before winter.
Blueberries are hardy perennial plants and generally require relatively little attention during winter.
Container-grown plants may need particular attention to drainage during very wet weather.
Yellow leaves can have several causes, but if the leaves show signs of nutrient deficiency while the plant is growing in soil that isn't acidic enough, the pH could be part of the problem.
Check the growing medium and soil pH before adding lots of fertiliser.
Young plants may simply need time to establish.
Other possibilities include insufficient sunlight, poor pollination, unsuitable growing conditions or a lack of compatible flowering varieties.
Small fruit can be caused by a number of factors, including the age and variety of the plant, growing conditions, watering and nutrition.
Congratulations.
You have discovered that birds also have excellent taste.
Protect your crop with suitable bird netting.
Growing blueberries organically is really about getting the growing conditions right from the beginning.
Give them acidic soil, plenty of sunlight, consistent moisture, good drainage and a little patience.
You don't need to cover your garden in chemicals to grow a good crop.
Healthy plants growing in the right conditions are much better equipped to deal with the challenges that come along.
And perhaps the biggest lesson with blueberries is that sometimes the best thing you can do for a plant is simply give it the conditions it naturally wants.
Get the soil right and your blueberry bush can reward you for years.
There is something very satisfying about growing perennial fruit.
You plant a little bush, look after it, watch it grow year after year and eventually you're standing in the garden eating blueberries straight from the plant.
That's the beauty of growing your own food.
It doesn't have to be perfect.
It doesn't have to be enormous.
And it certainly doesn't have to look like a garden centre display.
A pot, a plant, some good compost and a little patience can be enough to get started.
Grow what you can, where you can, and enjoy every little harvest.
