Cone pots

[OC2Texaspalmlvr]

So I used these pots to grow some Sabal Causiarum from seed. The problem I have with them is the very large hole at the bottom. After awhile the dirt seems to just fall out with any disturbance. Anyone have some good ideas or experience keeping the dirt in place ? Much appreciated in advance

I just use a piece of weed barrier.

Something like this.

Some paper towel or some "fluffed" cotton

I used a bit of cotton or long fiber sphagnum moss the first couple times I tried these. I think the large hole is to enable you to tray water them from below and maybe root pruning.
I ended up just putting some mulch in the bottom of 1 or 2 gallon nursery pot.  Enough so that the cone-tainer sticks up above the lip of the pot. Using peat moss, bagged potting mix and sand/perlite the soul doesn’t seem to fall out much at least in my experience so far. It looks like the holes in yours are larger than the ones I bought though.

this material is what I use for all my other pots. It's a tad bit of a pain once the roots grow thru it tho. Yeah these holes are excessively large but I'm thinking sphagnum moss might actually be the ticket ty @D. Morrowii

I don't drink coffee but I purchased some coffee filters for just this purpose.  Works pretty well for me.

I actually used coffee filters and they just didn't last. They eventually detiorated and the good stuff started falling out =/

Probably because your coffee is too strong!  haha   Good to know though, thanks.

I'll have to get a picture when I get home but I cut to size old pots that are cracked or falling apart into the size I need for the bottoms. Usually little square pieces for my liners. Works well for me but it's time consuming... then again if your not doing 100's & rather a dozen or 2 you should be good

A porous cinder of appropriate size

This is kinda what I was thinking. Cause I'm really only worried about the bottom hole.

I do the same thing with my liners. The problem I have is with the cones.

If you stuff some orchid moss (anything spongy and root-permeable) in the bottom and then place several of these cones into a larger (e.g., 3 gal) pot that has a several-inch layer of moss/coir/perlite/pumice/soil-mix, etc. at its bottom, roots will continue to grow through the bottom of the cone into that extra layer. The permeable pot-in-pot arrangement will stop pooling of water at the bottom of the cone's root zone (discouraging rot) and when you pull up the cone for transplant you will have a nice bunch of healthy (not root-bound!) roots ready for shifting up with much less trauma to the system for uninterrupted growth. I have tried variations on this sort of a thing in the past with excellent results, and it is certainly a much easier transplant than out of a traditional community pot of seedlings, which often seems to stall out growth for months, sometimes longer.
