Getting the best drainage for your container is critical for plants to look and perform their best. But what we've all been told about filling the bottom with rocks or cans, etc. is all wrong. I'll show you why that doesn't work and show you how to get the best drainage for your container. Then, watch my Urban Gardening playlist: • Urban Gardening

In real life (non-randomized) trials I've had best experience with small amount of gravel at the bottom. Less issues with blocked holes and water-logging after lots of rain. Given how much diffrent advice from experts is out there I guess it's much less clear cut and depends on many factors, soil quality, plant preferences, type and amount of material used, planter size and shape and so forth...

Dont stress, you seem to understand. Many videos on perched water tables say dont do the rocks at the bottom. But the exact reason they say why is also what contradicts them. Even a pot with straight soil/potting mix will have a perched water table. The stones just raise it from the bottom of the pot. Exactly like you said, case by case, situational difference, species etc. all come in to play. Ive done way more study and theory on this than practice, i agree and back you on what you say via experience.

I think the point of having rocks at the bottom is to help prevent the drainage holes from getting plugged with wet soil. Scale absolutely does matter, so your use of very little soil and so many rocks doesn’t make any valid point, other than that if you fill a pot with mostly rocks and only a tiny layer of soil, the soil will stay saturated (but only because there is not much soil!). Obviously if you flood very little soil with lots of water, it will stay wet longer than lots of soil with the same amount of water.

Brad. The point of using a lot of rocks in this demonstration for simply to illustrate more easily the science behind what happens to water flow when substrates of two different textures meet. I agree scale is important so that the more soil in the container the less chance of water collecting around the roots. But that's not the point of this video. It's to show that this does happen, wherever the interface is. And the primary reason people put rocks or cans or packing peanuts or whatever at the bottom is the myth that it helps with drainage, not to prevent drainage holes from getting plugged. Just use a screen for that.

Triplemania actually, Felix is absolutely correct in making his point that plants that are grown in a medium that can hold water for longer periods will not need to be watered as frequently. Your theory of water evaporation is not is incorrect however. Even in fabric containers very little moisture is actually lost due to evaporation compared to the amount that is absorbed by the plants roots as it takes a very long time for the moisture from the lower areas of soil in the container to wick up to the top to be evaporated. I wish you were correct for what it’s worth though lol ✌️

In my opinion, the one with the pebbles is better. I find that pebbles do help. The pebbles also help to prevent the soil from falling out. I find that if you add really big, misshapen rocks, it helps with drainage. There will be gaps. If you put a stone over the drainage hole, the water will come out, because the rock is misshapen and doesn’t have a tight seal. Whatever works for you though!🙂

I wish I’d found this video before potting up some of my succulents as per recommendations from other videos. I only put half to 1 inch of gravel but after a year when I was repotting I noticed there was green slime growing due to all the excess moisture. Thankfully my succulents didn’t die as I was watering every 2 weeks or longer as I noticed how moist the soil was. Never using gravel or rocks again. I do however use shade cloth cut to size on the bottom with all my pots. It works very well and allows airflow but stops soil leaking out. Been doing the shade cloth over 20 years and never had any issues with it.

I've had mixed results over the years but can see where over watering a container thinking it's draining but becoming saturated is a problem for the roots of some plants. I'll experiment some more this year since I'm planning on repotting everything due a harsh winter.

Id be curious what the results would be over the course of several days, especially if you used a more reasonable amount of rock. You've shown that a layer of rock can raise the level of a perched water table, but I wonder which pot's waterlogged section will dry out first? If you did a larger pot that only had a few inches of rock, you woulnd't waterlog the entire pot like you've shown here.

This has probably been mentioned, but I'm not reading all 314 comments (at this time.) I think most, if not all people fill the bottom of their containers (with whatever they choose.) so they don't have to use as much potting soil. Thus, spending less money. I'm sure that most people that live in an urban or suburban area just go to their local hardware store or garden center and buy bags of potting soil of their choice. That can get expensive and those bags aren't generally very big. Maybe 1 to 1.5 cubic feet per bag and it goes without saying, the bigger the planters the more money you're going to spend. I do have a tip for buying (larger amounts of bagged potting soil.) Buy in the winter months because off-season it's lower cost. You may have to order it from the store. All major chain hardware stores have online ordering available, and you can have it dropped at the store for pick up or some places offer for a few bucks extra to have it dropped at your house.

You should give it a try. Maybe in just one pot. Likes little experiment. I’ve been gardening for 30 years and learn new things every day. In the beginning, I believed that all my soil would fall out the bottom. So out of fear I put rocks in the bottom. I have not had that experience. It just doesn’t happen. Plus your plants have the added advantage of having more soil in the pot from which to draw nutrients. When the soil is depleted, they cannot go to the store and get food. They need all the soil they can get, so filling it with as much good soil as you can helps so much. And if you decide to add compost, mix it thoroughly with the potting mix so you have all the different sized particles mixed well. That way you are not creating the same problem you’re trying to avoid with the gravel.

After watching this video, I stopped adding rocks to my pots, and my plants have all died so quickly. Unfortunately, most planters sit on drain plates, so I've found that adding rocks actually gives the plant a bit of a "buffer zone" for the water to hang out where the roots can access it when they're ready, meaning you can water the plant less often AND not have to meticulously move the plant over to a sink-without spilling anything on the way-to separate the plate and drain it every time that dish fills up.

when you put different material in the container, you raise the water table.

You can create a false bottom in a large pot but you still end up with less soil volume and more roots in less soil.

You typically insert 3 of these "pot feet" under the bottom edge of the bot to raise it just a bit off the ground thereby ensuring that water does indeed have a clear way out of the pot. You can indeed google the term "pot feet" or "pot risers" to see what I'm talking about. Hope that helps.

The water in the first cup with the stones clearly flowed out instantly when you added water. It went straight to the bottom. So to say it didn't flow through is incorrect. Watch the video again. Secondly, of course it won't flow out the second cup as readily as there was more soil to absorb the water. As for root movement, of course it stands to reason roots can't flow through stones as easily.
@joegardenerTV
@joegardenerTV 5 жыл бұрын
As I noted in the video, of course the initial flush of water will flow past the soil and filler to exit the container, just as water exits an over-saturated sponge. It's the remaining water held in place by the carrying capacity of the soil above the second substrate that is where the risk lies. Saturated soil that does not move past this top / first substrate because of the change in texture of the material below poses the risk that the roots that share that same space as the saturated soil have insufficient oxygen because the water has displaced it. To your second point, wherever the change in substrate layer is, that's where the water will stop flowing after the initial flush. So yes, more soil is much better to allow water to flow past the roots. But if the roots aren't above the saturation point, they still have the risk of sitting in soil that is too wet.

But over time, the plant will send a lot of its roots straight through the window screening, and, when re potting, removing the window screening will be all but impossible without tearing off a lot of those roots.

What if you put some sands at the bottom of the pot instead of rocks/stones? Won't it develop a better drainage system than that of the only soil one? However, (according to your experiment) the universally accepted myth actually is- keeping the sands in the lower-middle of the pot, while soil on top & few rocks on the bottom.

Actually pure soil is not good either some plants just need perlite mixed in and sand so the soil holds less moisture or does't compact and retains air better, cos roots rot if there is no air in the soil, bonsai mix usually is just mostly stone like mix with barely any soil for example, some plants also better off in clay pots others in ceramic pots some type of rocks can also absorb water also to keep in mind, i would put in a stone barrier at bottom just so the roots dont sit in tray of water on saucer altho i dunno if that actually helps im not sure. Anyway a good soil mix drains as fast as it needs to so it cannot be overwatered, rather then not giving a little that does't reach the drainage hole, cos you wanna be able to wash out all the salts that acumulate into the soil.

Potted plants need water to flow through the soil mix to bring fresh air through to the roots. However, non-compacting, lightweight potting mixes will wash out of the drainage holes; adding rocks doesn't help. An ordinary (used is best) dryer sheet lining the bottom of the pot, covering the drainage holes, allows water to drain through, but slows it down and keeps the soil mix from getting washed out. The dryer sheets don't rot or fall apart - it's important to make sure water can pass through before using them.

and does this exeriment scale perfectly? if you have a 3 foot tall planter, are you going to end up with a 1 1/2 foot section thats clogged with water if you put rocks at the bottom, or is it going to be a 1 inch section no mater how big the planter is... The section of stuck water might just be more of a problem with a tiny pot like that cup.

joegardenerTV so if you had a pot that was a mile deep that eventually sat on some stones the water would stay in the soil for like half a mile deep? That doesnt seem right at all. Most experiments pike this need to be done at multiple scales to see what is actually happening. Its likeoy te section of saturated soil will be he same depth no katter how deep the pot is. So a mile deep pot has a few inches of saturated soil where is meets some stone.

Fair question. I would instead mix the heavier material in with the soil, so it's all throughout, vs. just at the bottom creating a seperate layer. This way you can still get the weight but not impede the drainage.

But how do you fill a huge pot with just soil? I have elephant ears and cactuses that are in HUGE pots. I bring them inside my house when Temps drop to cont. to enjoy them all year. I've done this for years. As some might know. Neither of types of these plants have large roots systems. I can not afford to fill all my pots with just potting soil, not to mention the fact they get way to heavy if I did and wouldn't be able to move them. So if your not supposed to fill with rocks or another type of "filler" substrate, then what is your suggestion please. And thank you!

The same principle applies to your in ground soil. You won't improve drainage by adding sand. in fact, you'll make it worse. If you're dealing with perennials, consider amending the planting area all around where your plants will grow. Incorporate organic materail into the existing clay soil, but not just at the bottom of the hole.

I just came across an article that mentions to avoid placing saucers underneath outdoor container plants because saucers full of water will keep the soil in the pots wet (unhealthy condition). I’m so new to this..I don’t understand, if you don’t need a saucer, does the pot still need a drainage hole? If it doesn’t have a hole, how does water drain? Help please!
@smievil

feel like having some sort of drip tray that can hold the pots but lets water run through could be good, or placing pots on soil. you can water plants by filling up the saucer with water, and if you have a fast draining soil the water would quickly just end up in the saucer, one could empty the saucer occasionally but that seems like a lot of work. probably good to consider where the water's gonna go once it run through the draining holes, some flowers don't want to stand in water, and pot should probably not be standing in water for prolonged periods of time either.
