Blueberry trobles

    6 responses

Hi. I'm a newbie to growing potted blueberries for the simple reason when I move they are coming with me. Since mid spring 2015 I purchased a blueberry burst, sunshine blue, legacy, briggata and a heaven. All died except the sunshine blue, which isn't doing all that great, I've purchased in the last week another healthier sunshine blue, and a burst. Living in western Sydney near Penrith temps have been extreme over the last two months, watered nearly every second day, reported twice after deciding my mix was terrible. ( cow manure, orchids and azela mix with blood and mix and liquid sulpher to help with acidity, I have noticed all azealea type potting mixes never seem to be of a acidic reading, allways a reading of 7 . Leaves started to brown up and go crispy about a month ago, ph was about 3 or less, I know they like 4 -6 must of over done the liquid sulpher. Anyway, I ended up reporting a third time, Got my hands on coco peat from a chillie grower who was changing crops. Ended up mixing this with new orchid mix and azealea mix. And tipped all the old potted mixes with the very low phs into this mixed and watered and came up with big pile of really gd looking mix, the ph altered after doing this to around 4.5 _-5. Reported the new plants I bought into this I made and also the crispy browned leaves plants of the blueberry heaven, burst, and briggata. These 3 now have all died, I think they started dying a month ago as I mentioned, but all the blueberry plants Senn to like this new mix, I'm avoiding using the liquid sulpher or white vinegar in watering cans which I had being doing. Everyone says they are easy plants to grow, why am I having troubles, I'm hoping the weather will calm down now with the heat. What can I do during autumn and spring to ensure my plants stay healthy for summer.

Hi Nadmik

I'm certainly no authority on blueberry growing, but I have 8 different varieties of blueberry growing in pots that I purchased over the last few months.

The mix I use is a 50/50 mix of azalea potting mix and coarse pine bark chips. I got this info from plantnets' website regarding potting their Blueberry Burst. I used this mix for all varieties and they're all thriving. The only thing I've found is that because it's quite an aerated mix, I have to water regularly.

Hi,
I agree to use 50/50 azalea mix with pine bark chips. I have potted all my plants (8 x the biggest pots i could get) in this mix and i also water once fortnight with potash solution and they are all exploding with flowers...in autumn. They are shaded for the afternoon also. Goodluck.

I hate talking brands but ive tested a couple and the Debco Azalea was the most acidic all others were neutral and returned for my money back.

Also if its really hot BBs need watering 2x a day as roots are very fine surface ones. Spoke to Plantnet Guy at Melb Garden Show and says in their tests the course pine bark with Azlea mix worked a treat.

A week ago i upsized into 430mm pots my Nellie Kellie & 2 Bursts - major addition was a couple big handfuls of german peat moss for each pot.

When i planted my Heritage raspberries i added a bucket of the peat to ground mix and they grew like rockets and had lots of rasps when they said would take another year.

Hope the above helps you Nadmik.

I wonder if you are killing your plants with kindness. They are often commercially grown in gutless drained peat swamps with limited fertilizer added. Are you giving it too much strong fertilizer. Many plants that grow easy can be killed with too fussy attention to potting mix and feeding.

Hi Nadmik

My experience has been that they don't really like their roots being disturbed too much. Can be tricky!

Tnx for all the great answers. Certainly a learning curve. My new plants are doing gd now, now that I've left them alone. The potash feed seems to be quite common for potted bb. Will try. When it comes time to repot I'll definitely go with the common theme of coarse pine bark and azealea mix. Now I'm trying my hand at a Tamariilo tree which I found at flower power. About 1.2m high. Was covered in powdery mildew, am treating it with fungal spray. All the best nadmik
