Are you growing blueberries in your organic garden? I’ve got a few blueberry plants growing in 10″ pots. We’ll be moving soon, so I didn’t want to put them in the ground and I was curious to how well they’d grow and fruit in pots.
I potted them up into the 10″ pots about 6 months ago – so early spring here in South Australia. They really took off ( I always fertilizer – with organic slow release pellets – when I pot up ) over spring, were flowering in summer and we had a nice handfull of fruit from each plant late summer. Not bad for plants that are only about a year or 18 months old.
I think one of the reasons they did so well, given that they need a pH around 4.5 to 5, was that I added pine needles as a mulch around the top of each plant (being careful not to get the mulch too close to the stems). Then each month or two I throw coffee grounds (not hot!) on top of the pine needles.
So every time I water, some acidity is watered through the pots, keeping the soil beautifully acid – just the way blueberries like it. I’ll probably refresh the pine needles when I put them in the ground, once we move to our new property, which I’ll tell you about soon.
Blueberries are a superfood – they are extremely good for you, so if you have the right climate, give them a go.
Just by the way, both rhododendrons and azaleas love acidic soils too, so you can use this method on them and they’ll really reward you for your time.
Happy Organic Gardening, Healthy Living…
