More Tips for a Successful Garden

While editing Episode 406 of the Garden Basics with Farmer Fred podcast (out now), I was taking copious notes, about all the great garden tips Don Shor and I discussed in an episode that was ostensibly a chat about growing tomatoes this summer (we both like Cupid, despite its propensity to sprawl). In fact, it was the most notes I have ever taken for any episode. Were you taking notes, too, while listening? If so, I hope you weren’t driving.

But I’ll make it easier for you: check out the transcript of today’s episode, especially the more accurate transcripts that you’ll find at our website, gardenbasics.net, or at our podcast uploader, Buzzsprout, and discover your own “Aha!” garden moments.

TIP #1: START WITH EVENLY MOIST SOIL

We have discussed this several times on the podcast. First, with America’s Favorite Retired College Horticulture Professor, Debbie Flower, when talking about reusing old potting soil for container planting, in Episode 172 in the Garden Basics podcast. Debbie stressed the importance of getting the soil thoroughly moistened before planting:

Debbie, it's that time of year or and people are going to go out to get plants, or they're going to get seed. And they may be buying soil. But before they buy soil, they may take a look around their yard and they see all these pots with no plants in them, but they're full of soil. There might be nurseries that might say, "Oh, you don't want to use that. You need to buy our new soil." But that old soil that you have, I guess it really depends what's in it and what it is, and what it needs. Right? And can it be reused?

Debbie Flower

Yes, I reuse potting soil all the time, I have many instances where I look around and there are pots with dead things in them. As I said to my cousin, I still kill plants, I just know how to do the autopsy. I typically know or have an idea of what killed them as well. I take out the what is left of the plant, there's often a decent root system, I'll bang it around on my potting bench and get off as much of the container media as I can from those roots. And notice I say container media. This is not field soil. I use kitty litter boxes that I bought specifically for the purpose of mixing media. And I dump it in there, mix it up with whatever else I have and reuse it. I very often add a rock component to that reusable media and some new bagged container media. Container media is not soil, it is organic matter. Plus some typically rock components. Peat Moss, coir or compost are usually the organic matter. And then the rock components are perlite, vermiculite, pumice, sand, something like that.

And it's often one part of the organic matter to two parts of the sand component. And the reason for that is that over time the organic component breaks down. And as it breaks down, the particles get smaller. And the space between the particles where the air and water hang out in a container gets smaller and the plant starts to suffer. So a plant has died in the container media. It's been in there some period of time and a container, the organic component of that container media has broken down. So the pore spaces, the open spaces between the components of container media have gotten too small, or they've definitely gotten smaller, they may have gotten too small for roots to actively live in there. So I want to fix that. That's one thing I want to fix, is particle size. So I do that by adding some new media from a bag and usually more rock components. Mix them together, get the texture I do very much by feel and I don't have recipes, and then I'll reuse them. I will never reuse media to start seeds in. To start seeds, you want things sterile. You want the pots to be absolutely clean and you want the media to be unused. So I'm not using it for that. But I will move my houseplants up to a bigger size or my seedlings that I started in six packs all the way up to four inch pots, something like that, using this reused media. The other thing that I need to worry about with the media is the salt component. Salt is fertilizer. Fertilizer has to be in the salt form for the plant to be able to take it up. It has to be able to dissolve in water and move to the plants roots and enter the plants roots. And so that's the salt form. And if there's too much of that in there, the pH of the soil will go up, so the soil will be too alkaline. When that happens, then nutrients that are in the soil become unavailable to the plant. The easiest way to do that is just flush the the media with freshwater for several minutes and allow it to come out through the drain holes of the pot. But yes, I absolutely reuse media frequently.

To your last point there. One thing I do is, I get myself a five gallon bucket. And I will take that old container mix and put it in the bucket because usually peat moss is part of that. It is hard to rewet. So I put it in a bucket with no drain holes, I will put that soil mix and then fill the bucket with water and then go do something else. When I come back several hours later, that moisture has basically permeated throughout that entire body of that potting soil. And I then transfer the potting soil to large plastic containers with drain holes and let the whole thing drain. And then I can get in there with my hands and grab the soil and refill whatever pot I was going to do, knowing that it's thoroughly moist.
