Just FYI

Here is a link that might be useful: pine fines

Thanks, cold_weather_is_evil. But I live in Quebec, Canada, and I couldn't find it on the Canadian Home Depot site.

holy smokes $9.99 per gallon that's some spendy stuff

Use a wheelbarrow, add the peat, use tap water to start, then keep mixing until it's all wet, then fill the containers.
I wait overnight for it to expand the peat and absorb all the water.

berry_Bob. $9.99? We are constantly being ripped off over pricing.
I recently priced Scott's 'Weed be Gone' in the USA, about $15. Just priced the exact same size item here are Home Depot $39. That's a Canadian company for you, greedy bunch a AH's.

I don't think a little bit of tap water, enuff to wet the peat moss, is really going to do anything significant to the mix or the plants. Over time with regular watering, yes I believe it has its impact, but not when just a little bit is used here or there. Adding a surfactant to the water will make a big difference. There are commercially available surfactants for use in potting mixes, but you also could use a mild liquid dish detergent. A couple drops per gallon will help overcome the hydrophobic tendency of dry peat moss.

Ok great, thanks! What do you think of the soil composition? Should I add perlite or anything else to it?

I know Drew has suggested using various Fafard mixes but I have no experience with them. I question if you will get any better results with a 50 50 mix of Fafard and peat moss though. In large part it seems like just more of the same, perhaps even more poorly draining. I suspect that unless the mix is in contact with the ground through the pot holes, you're gonna have some water logged areas in the bottom of the pot. Then again it might be what is needed, I don't know.

But I wonder if there isn't something else that kept your blueberries from flourishing. While the Fafard has some compost and amendments, I wonder if there might have been some nutrients lacking. Did you use a fertilizer with micro nutrients?

It is specifically designed for blueberries and acid loving plants. You'd think it would be good enough. I only used Miracid, and I think that's what made them have dark green leaves, but I remember overall, the new branches looked weak.

I always keep a space between the pot holes and the ground, so the container sits on bricks. And watered with rainwater.

To moisten the peat moss, add hot water.

If you get the peat moss in a bag or bale,
prop up the bag/bale;
cut a circle in the top of the package;
pour in hot water; wait at least overnight.
Add more hot water if needed.

Ditto to Jean.

Use HOT water.

adding to the hot water suggestion ...

wet the peat FIRST.. then mix with other pre-wetted media..

THEN PLANT...

the only real problem you have.. is you did it backwards ...

NEVER plant a plant in dry media... how do you know it wetted thru the whole mass.. and didnt leave a dry gob in the middle ... [been there .. done that .. plant died.. i learned]

remove plant.. dump it all in a galvanized wash tub.. wheelbarrow.. kiddie pool.. wet it .. replant ...

If you can use Holly Tone, and cut down on the Miracid using only 1/4 dose a week. Stop using it August 1st. Weak growth is kinda common for blueberries. They need as much sun as possible. I would not blame the soil. My guess is too much fertilizer, and/or not enough light.
If you can fine spray the peat with water, it will absorb better. I myself have never really had much of a problem, as a good soaking after planting seemed to be enough. I use it dry myself.
I like to add Diatomaceous earth. I make my own soil.At this point I'm leaning towards more pine bark than peat. But basically use a 4-2-1 mix at this point. 4 parts pine 2 parts peat and 1 part DE, particle size like perlite, not the food grade. I use Optisorb. It's an oil absorbent that is 100% DE.
In this photo of my pots you can clearly see the DE.

I have been adjusting this mix all year, and feel this is best at this point. Sometimes I add one part Fafard mix also.

I add a lot of other stuff too, I add azomite, rock phosphate, worm castings, organic fertilizer, dry molasses, mycorrhizal fungal spores , and alfalfa.

I also at some point water with Biota Max to add beneficial bacteria.

This blueberry plant is 2 years old
