It's a good idea, as long as you are *truly* making good use of the water you keep dumping out. In my area, doing that kind of thing begets dirty looks from others who care about water usage during our droughts. When I rinse media to bare root using garden hose, I end up going around the yard to water it with the washout. This worked great, until I ended up getting a bad batch of trees that had gall and nematodes (these were expensive trees from a very reputable grower). I spread it everywhere, including a patch of my small orchard.

I'm new here and just read that long thread on container drainage and now have some ideas for improvement. I always recycle soil. There is no way I could possibly mix new soil for my entire container garden each spring and expand it. This year I have already bought over 130 40 lb. bags of dirt for the installation of new planters! And that was a lot of work. My big wildflower containers which are 8'x2'x12" deep hadn't been changed in 4 years. In the fall I amend the old soil with compost, get rid of the old plants and rootballs, loosen it up, and plant the seed. For containers that don't have perennials, in the spring I empty them into my dirt mixer (which is one of those large Rubbermaid storage things I found in the alley a bunch of years ago), add some compost and new soil and perlite, mix it up and it's ready to go into a new planter. So far I found Menards to have pretty decent dirt and I've tried dirt from all the places around here. I mix one bag of their cheap topsoil (which is pretty good with very few clayballs) with one bag of potting mix with 1/2 bag of mushroom compost and a coffee can of perlite. It may not be the best soil but it works. I grow wildflowers, veggies, herbs, and only a couple of annuals. Last fall I had a big ficus tree and a 2 year old rosemary that I grew from a seedling die on me after bringing it inside last fall. I now think my soil mixture and lack of drainage had something to do with that. These discussions here have been very helpful and I'm going to experiment using wicks and maybe there are other things I can add to amend the soil to make it better.

I love wintersowing! Lol. I tried it this winter but with very old seed and got okay results. I can't wait until next year when I try with fresh seed. My parents aren't very rational sometimes. If they have their minds set on me not putting on a fan for seedlings, they're going to stick to their guns. If one reason they give for me not having a fan is made void, they'll come up with another, and another... Yes. It is pretty odd. But it's a whooooolllleee other issue that no one would want to get into here! As per my original post, I have tried chamomile tea, cinnamon, hydrogen peroxide and other home remedies but no luck. I have heard of No Damp but haven't tried it yet. It'll probably be the next product that I try. I really wish I could find something systemic though that won't cost an arm and a leg. I can't afford to pay what commercial growers pay for Banrot and the other things they order for damping off.

What Pam said ^^^; and, the most significant factors in determining whether or not a grow medium is appropriate are whether or not the soil contains anything phytotoxic and particle size. Container media do not wear out, even though this idea is often suggested. Soil particles just become smaller and smaller, which increases the amount of water a medium can hold while decreasing the amount of air porosity. There is no question it's better to err on the side of more porosity and water more frequently than to err on the side of too little porosity and see the planting suffer from poor root function or even wrecked root health. One cannot take a quart of fine material, like peat, coir, or sand, and "amend it by adding coarse materials like pine bark. That practice actually DECREASES o/a air porosity until the fraction of coarse materials becomes so large there is no longer enough fine material to fill the larger spaces between the coarse particles. Two observations about mixture reaches the "threshold proportion", which occurs when there is exactly enough fine material to fill all spaces between large particles: 1) It will have less aeration and be more difficult to grow in than peat, coir, or sand or a mix thereof. 2) Adding additional coarse material to mixtures at or beyond the threshold proportion such that the coarse material becomes a very large fraction of the medium (around 80%) quickly increases o/a air porosity. Container media is all about structure and its ability to retain that structure for the expected life of the planting. So, as Pam and I mentioned, there is little sense in reusing a medium, the structure of which is inappropriate. That seldom ends well. Used media can be used as the much smaller fine fraction we might add to coarser material when putting a medium together, but even then, particles of slightly larger size 1/20-1/10" (about the size of coarse ground pepper) would be the better choice. As in life, our growing experience and how much reward we're able to realize from our efforts is a product of the decisions we make. There's no judgement to be made about what a grower does or doesn't do, we all order our priorities differently, but that doesn't change the fact that what the grower chooses will always have an impact on how the plant responds.
