Newbie: Gritty mix w/o bark? Unscreened turface in layers?

8 years ago

I am proud to announce that I rounded up 100 lbs of turface and grit (made my son buy it in Charlottesville and her brought it when he drove to NYC). Also ordered reptibark (the large bag) online.

I thought I was ready to roll BUT: the bark is huge compared to the turface; the layer size grit looks huge next to the screened turface; and the screening of so much turface might just be too much for me to manage in my small apartment.

Plus Ive read and reread hundreds of posts and threads and I do understand the principle but still have questions and uncertainties galore.

My main challenges are a. The screening - the mess without having the outdoors or a big space plus not being able to figure out the right size of screen to get the right size particle b. The bark I have seems too big and putting it in a blender or hand cutting it isnt an option for me.

I saw and copied this (below) from Al about using unscreened turface during my many hours of reading up on the gritty mix and my questions are

1 what is the downside of doing this barkless version without any screening,

2 can I still add the bark to this if it's a bigger size?

3 is there any other solution for me to use unscreened turface, grit and bark - maybe in some other proportions? Or adding a wick?

i realize everyone must be tired of gritty mix questions but it's actually very intimidating for someone doing it for the first time! Thanks for your patience


"I've actually been thinking about writing a thread about growing in mostly unscreened Turface. What you can do if the container is deep enough is layer your soil. Water won't perch above another layer unless the particles in the lower layer are more than 2.1X the size of the particles in the layer above. If you start with a 2-3" layer of grower size grit, #2 cherrystone, or equal, then add a layer of unscreened Turface and grit at 1:1, topped with just unscreened Turface, you'll have plenty of water retention, great aeration, and no perched water. You'd have to stay right on top of fertilizing, but your plants should really love it. Plus, there is no waste and no real need to screen, though I'd still screen the dust out of the grit. Bark would be optional.

    Which is why it's so much easier, cheaper & faster to do 50/50 C&S mix combined w/ either perlite or pumice.

    Works just as well for many of us w/out all the extra headaches.

    Screen the bark. Reptibark is too large, on average, for Gritty Mix.

    Lmontestella,

    thanks for the good advice but I'm at the point of no return. Five giant heavy SACKS of otherwise unusable gravel, fired clay and tree bark has to somehow find its way into the pots of my plants....

    Hi,

    I use reptibark when I can't be bothered to go the nursery and her bark fines. What I do: if the plant is already well established, I use the bark as is with the biggest pieces of coarse perlite. I sift the perlite first to get the huge pieces. The plants I put in this particular mix are the ones that have done the best.

    Option b: if the plant has little roots or a few roots, I sift through the reptibark, as Josh suggests, and get the smaller pieces. It can be kind of frustrating if you end up with a bag that doesn't have many smaller pieces, but it usually works out okay.

    the best option, imo, is to buy bark fines. They are not too costly and they make your life sooooo much easier.

    Thanks Lauren and Greenman.

    I'm trying to avoid screening and sifting due to space and dust issues, so you're right that I should just buy the right size fines - but that's the problem - citylife has its limitations. I can't find them except for tiny bags online that cost a fortune and I have a whole bunch of large plants.

    i just found this on amazon - price seems too good to be true for the perfect size. Pine bark that apparently has been heated to be aged?? So can you tell me if this so-called Deep Jungle Bark (pine) would work for gritty?

    Thanks much for your time and help
