I hope Brian chimes in because he uses it with great success and is also in Canada. His trees are spectacular and huge. I tried it this year for my outdoor containers and really liked how fluffy it is. I have not tried it for my citrus because I have them in 5-1-1, which is easier to lift for me.

Thanks Laura for your answer. Among others I have a limequat that has come back from almost being dead but it still has a ways to go. I've had it for 2 and a half years and it is still in the original 3 gallon pot.

I have no doubt that it would benefit from a repot and fresh soil as the old soil has definitely compacted quite a bit.

I need to repot it sometime soon. I also have a new Meyer that is new but in a 1 gallon container and has a beautiful green canopy that is substantial for that pot size so I was thinking of repotting it as well.

I think I will wait to repot my eurekas and Persian lime till next summer.

Anyway, glad to know that Brian uses that mix. I am curious to hear his experience with it.

Oh, just googled this and looks like it is available here in my area. Maybe worth to try? Does $25 for 3.8CU sound like a reasonable price? My Tangelos seem to be somewhat more finicky then my other citrus. Maybe try with one and see if it makes a difference.

I have been using promix BX for my other potted plants. It's fantastic. So I tried it on my citrus. I ended up doing a 2:1 promix:perlite mix. I've got seedlings and 3 young plants in it for over a year now. Including a limequat which I left in the grower mix and later put into the promix. It has not done well. Discolored leaves on most of the plant that later fell off.

Was just about to pull them out and possibly pot up, so I can't actually say what the roots look like.

Remember to be careful of your watering.

Thanks so much for your response :). From my limited research the BX contains vermiculite which may not be ideal for citrus because it holds on to water. The HP on the other hand has no vermiculite and is a very fast draining mix. Furthermore the pH is between 5.2 and 6 which I understand is more favourable for Citrus.

Honestly I tend to be very very careful and timid when trying something new and I do try to research stuff but more than anything I value input from others such as yourselves who have had experience.

Thanks !! :)

One more thing to consider is that Brian has a spectacular greenhouse. His citrus spend the winter there, which may help make the mix more bearable. Mine come inside all winter and I have found that even with the 5-1-1, my watering drops down to maybe 1x every five days or so.

I'm not sure about the differences in mixes. I got my BX several years ago and I'm fairly sure there is no vermiculite in it. But you are right, I'd probably opt to omit it from a citrus mix because I don't know for sure how it performs. Like you, I tend to be careful and do a lot of research.

Did you ask on the container forum for help sourcing PBF in your area?

I use Promix HP instead of plain peat for my 5:1:1 mix . HP I believe has coir in it already . I have used it straight up for non-citrus houseplants . Recently they came up with HPCC - High Porosity Chunk Coir , should be interesting to try that .

Where in Eastern Ontario are you located , here in GTA I get Pine bark fines from GroBark , also AllTreat hasPine bark mulch thats available in Home Hardware

Thanks so much for the tips. Somebody commented on the home hardware pine bark mulch as mostly the consistency of a lot of "match sticks". So I was hesitant to buy that.

I am 3 hours east of Toronto :( I think what I will do is get the Promix HP and mix it with pine bark nuggets that is available at Lowes. Problem is I think those nuggets look a little larger than the desired 1/8 inch pieces so I just won't use as much.
