Redwood soil?

Posted by ryan_tree VA (My Page) on

What would be a good soil to keep my very small 1 inch Coast and Dawn and Giant Sequoias in? Would it be something like regular potting soil, vermiculite, or peat or something else? What soil should I keep them in?

RE: Redwood soil?

Potting soil (which is usually mostly peat) and vermiculite are not good for any trees, which need much faster drainage, usually with a mostly grit mix - think aquarium gravel, a little perlite and a handful of bark chips, which is easily come by in orchid mix bags sold wherever potting soil is found. While redwood does need more water, or water more often, than e.g. pines or maples, if drainage isn't fast, and peaty soil just holds water in forever, you'll end up with rotting roots (so never let the pot sit in drain water either).

So, what should I put them in? Gravel, bark Chips and perlite? What is perlite?

RE: Redwood soil?

If you go to any place that sells potting soil (like Schulz) in bags they should have some - it's white granules and hardly weighs anything, but helps with fast drainage.

but is it good for redwoods? Do you recommend that brand?

Perlite is great for just about anything!
It creates excellent drainage, and it's lightweight.
You should be aware that there are two "sizes" of Perlite commonly sold: large granule and fine granule. You want the large granule stuff - 1/16 to 1/4 inch in diameter. The larger pieces can be crumbled or culled out for a more even particle arrangement, if you wish.

I like to use small bits of charcoal in my mixes, too.

Where can I buy it?

RE: Redwood soil?

You can buy perlite (heat-expanded volcanic glass) at most nurseries or garden centers. I bet if you called your local nursery and asked about perlite, they'd tell you they have it in stock. As far as brands go, I think that perlite is fairly consistent across brands - the important thing is to buy a bag with granules that aren't crumbled to powder. I've used a few different brands, without complaint.

What if I mixed regular potting soil, vermiculite and peat together? Would this work?

RE: Redwood soil?

Re-read the first response to your question in this Thread, and you'll have your answer.

But if you have your heart set on "regular potting soil, vermiculite, and peat" for some reason, go ahead and try it and see how it does.

Just remember that you've been given tips for a far superior potting medium, which will be much better for your plants. Good luck.

So, all I do is mix perlite and what? That is good for trees? I am about to go and get some but what else do i need soilwise for my redwoods?

Good mornin'!
Yes, it's good for trees. Plenty of free-drainage for the roots - root health being the key. What Lucy wrote: "a mostly grit mix - think aquarium gravel, a little perlite and a handful of bark chips, which is easily come by in orchid mix bags sold wherever potting soil is found."

The bark chips satisfy that organic component in the mix. As the bark becomes finer and finer, it adds the typical "soil" look to the mixture, if that's what your last question is asking. Really, though, you don't need any organic matter at all - as Tapla, one of the poster's here, has said, a plant can be grown in glass shards as long as water and nutrients are provided. This is to illustrate that free-drainage (oxygen for the roots) is crucial for plant health - and, by eliminating (or limiting) organic matter, composts, peats, et cetera, we can better control the amount of moisture throughout the potting medium.

I was just at a nursery, about an hour ago, and I bought a bag of fine orchid bark for $2. The perlite was about the same, along with volcanic pumice and charcoal.

Let us know how it goes, and take pics if you can.
