The more absorbent the potting medium, the taller the perched water table will be. Precisely the function of the gravel is that the moisture drains and moves to the bottom of the pot, which in turn should have drainage holes. From the North Willamette Research and Extension Center, Oregon State University, Physical Properties of Container Media. One thing I did know was that when you pot up a plant, it’s good practice to put rocks in the bottom of your plant pots. If there is bits of dirt stuck to it, its still wet, if it comes out a bit dirty I assume it's still a bit moist and if it's still clean it's totally dry. Ummm I have to disagree with this. Capillary action is created by the cohesive and adhesive forces of liquids. Post was not sent - check your email addresses! This mixture contains huge air spaces and drains extremely well, barely retaining moisture in the bark pieces, so there is no perched water table. ... We’ve all heard the advice to put gravel in the bottom of a plant pot, and some of us may even have done it. Cohesive forces are forces of attraction between molecules of the same type. Cactus and succulent growing mediums for pots are a coarse, open mixes made with some organic matter to retain a little moisture, and plenty of gritty material such as crushed quartz or other crushed rock, which act like a sandy soil and lets water pass almost straight through. To support our claim, we refer to this educative article on Illinois University , according to them “ It is a myth that a layer of gravel (inside the bottom of an individual pot) beneath the soil improves container drainage. A better choice is placing a coffee filter in the pot to contain the soil. My nest article “How to Improve Drainage in Plant Pots, The Proper Way to Do It” is coming soon! In the past, it was recommended that broken pieces of clay pots, rocks, wood chips or Styrofoam packing peanuts be placed in the bottom of pots as filler and to improve drainage. In the first pot, place only potting mix, and in the rest, put increasing amounts of gravel beneath the potting mix. Polar molecules act like magnets with north and south poles, the (+) positive charged atoms and (-) negative charged atoms of these molecules are attracted to one another. Hi Paul, thanks for your comment, I had a look at the links you suggested and only included the Oregon State University one, it was the only one which provides any real scientific explanation, albeit a very limited and simplified one.

Crocking was supposed to encourage water to pass down from the potting mix into the gaps in the coarse layer below and out through the drainage hole. In all the other pots, add increasing amounts of gravel at the bottom, then fill with potting mix to within 2.5cm (1″) of the pot. So how can we turn the problems created by adding gravel at the bottom of pots into solutions? How completely they dry out depends on the plant, which is why I’m so in love with moisture meters. The absorbency of the potting medium pulls the water upward and stops the water draining out, no matter what is underneath. Unauthorized use and/or duplication of this material without express and written permission from this site’s author and/or owner is strictly prohibited. Capillary action by definition is the tendency of a fluid to be raised (or suppressed in the case of mercury) in a narrow tube (capillary tube) due to the relative strength of cohesive and adhesive forces. If you’re a chronic overwaterer, then I’d definitely suggest repotting to do away with that perched water table. Water each with the same volume of water, wait till they drain, and then observe the perched water table. I was unbelievably lucky that they hadn’t spread to the other plants. As I already mentioned, you just need one rock, to keep the potting medium in the pot. If you want, I will leave you my contact and I will explain it to you with a practical video. The reason why I wanted to alter the composition this way is because the surface is completely drying up in one day when it gets full sun if I use equal parts of clay balls and compost. Should the soil be really compacted, your best option might be to repot the plant entirely. Adhesive forces are forces of attraction between molecules of different types. The more moisture retentive growing medium/potting mix available, the less often a plant will need to be watered, as long as the pot is not too big. Capillary action, which exerts an upward pull on the water, causing it to be retained, saturating the potting medium.

Last notable comment in the article mentioned a stone on the drainage hole to prevent soil leaching from the pot. We can see that the common practice in horticulture to increase drainage in pots and containers is to alter the composition of the potting medium to increase the air spaces within it, and not by making changes to the the space beneath the pot. The pebbles help water move through the soil to avoid rotting of the roots. Wonderful informative and well written article-thanks‼️, Thank you for this enlightening article. A shallow rooted plant in a tall narrow pot will have similar issues, there will be too much overly wet potting mix which the roots will never be able to reach, and if the potting mix stays too wet for too long it will break down much faster, and sink down, dropping the level of the plant in the pot. 1:1 ratio. A layer of gravel or rock on top can help prevent excess drying. One of them had one part potting soil (very rich in compost) mixed with one part clay balls on the bottom of the pot and then slowly decreasing the content of clay balls towards the surface. By exposing the roots and letting it sit, preferably, overnight. So the answer is no, there’s no need for rocks. I think I’ve made my stance here pretty clear, no? So why bottom water? Only a few months ago I knew NOTHING about houseplants.

In this section we’ll go a bit deeper into the science if you’re interested, if not, please skip to the next section. The upward motion of liquids against gravity, known as capillary action, is a combination of: To put it another way, capillary action is a combination of the effects of adhesive and cohesive forces displayed by water. As a final thought worth pondering, it’s curious how gardening has as its foundations the applied sciences of horticulture and agriculture, yet it’s filled with so much dogma and myths, very strange indeed…. So if you have a pot, like in your illustration, and the pwt is at the bottom 3 inches of the pot (for example), if you replace those 3 inches of soil with a very course medium like clay pebbles (which has much lower capillary action, then more water at that level will drain out of the drain holes in the pot. Succulents naturally grow in sandy soils that drain quickly, so their roots should never be left in wet soil. You have a nice blog, read a few articles till now and looking forward to your next ones! It prompted me to look around. I have some succulents in pots ( small, ... For my plants I have tomato plant food, do I need something for bottom rot.

The size and shape of the pot makes no difference, it doesn’t matter if a pot is tall and narrow or wide and shallow, neither if it’s big or small, if the growing medium/potting mix is the same, the perched water table will always be the same height. You are completely incorrect in your article. Because the roots with curl around the rocks and you’ll have a hell of a time picking individual rocks out of your plant’s root ball. Give plants as much space to spread their roots out, relative to what they can use or need.

Thanks Elizabeth, that’s an excellent idea! The simple way to test this is to make some clear plastic pots by cutting the tops of clear plastic soft drink bottles and making the same number of holes in each, so the perched water table can be viewed. The plant in the pot which had only potting soil I noticed it retained too much water on the bottom and was hardly drying, which in the end led to root rot. We’ve already established that putting a layer of gravel in your pot won’t help the water drain quicker – it’ll hinder it in fact.

This is speculation on my behalf, but I suspect that the reason gardeners traditionally used gravel in the bottom of pots is probably because pots were traditionally made of terracotta clay rather than plastic, and these pots only have a large single drainage hole in the base of the pot. Answered. Beds. Hi Johnny, thanks for your question! The only way that gravel at the bottom of the pot will increase drainage is if the pot has insufficient drainage, either due to not having enough drainage holes, or by having blocked drainage holes. Which house plants grow the quickest in the UK? The pwt will NOT be “higher up in the pot”.

It makes sense to fill the pot to a certain level with rocks, just to save a bit of cash. Since any decent quality potting mix must retain some moisture, it needs to contain material which will absorb and retain moisture, much like a sponge does.

The saturated zone is at the bottom and the unsaturated zone is at the top because gravity causes the water to head down through the soil. If you’ve read this far, and still aren’t convinced that putting gravel at the bottom of a put just pushes the perched water table up, but doesn’t improve drainage, then I have two diagrams and two direct quotations from authoritative sources to illustrate the point: Hopefully that’s convincing! If you use the same potting medium, irrespective of the size or shape of the pot, the perched water table always stays the same height because it is determined by the wicking ability of the potting medium, as gravity doesn’t change. Adding gravel into the bottom of  terracotta pots creates a small water holding area for the excess water that would normally drain out on its own  if the gravel wasn’t there to collect into if the single drainage hole become blocked.

The gravitational force can only exert a limited downward pull on the water against the upward pull of the capillary action, and no more. If we do a Permaculture functional analysis of the outcomes our outputs, we see that the technique reduces soil volume and raises the saturated perched water table. The way to increase drainage of the perched water table is to add materials throughout all of the potting medium to increasing the air spaces in the mix and reduce capillary action. One thing I did know was that when you pot up a plant, it’s good practice to put rocks in the bottom of your plant pots. Different growing media will have different perched table heights, the more absorbent materials will have higher perched water table, and the less absorbent ones will have lower levels.

Growers of Cymbidium orchids use an orchid mix which is composed mainly of  coarse 20mm (3/4″) composted pine bark pieces. Mixing either of these amendment materials right though a potting mix will increase aeration, improve drainage and reduce the height of the perched water table. Anchor one end of each cord in the tub with a rock or brick, and coil the other end around the soil atop each pot.

With these pots, it was a traditional practice (and still is) to sit a very loosely fitting stone over the hole to stop the potting mix falling out. Here is a simple experiment that can be set up to determine whether adding gravel at the bottom of a pot improves drainage or not. Now that we understand how the forces of adhesion and cohesion within liquids create capillary action, leading to the formation of a perched water table at the bottom of an absorbent medium, we can see that it won’t have any effect on these forces in any way at all. The water will move downward, some of it will drip away, and some of it will be retained. Specifically, small stones and pebbles can be added to larger saucers to add texture. Iann i dont mean to sound rude or anything but i gota dissagree with pots dont needing some kind of pebbles or pumice or something on the bottom of the pots, i always use pumice/perlite or pebbles or for my neps and such i use a mix of perlite & orchid bark chips & charcoal for better drainage, helps keep the water from staying at the bottom of the pot even after it drains thru the holes, helps keep the roots aired insted of sitting in any leftover moisture, thus also stops any potting … That’s how people find common ground for understanding! You could force more water to drain out by adding another downward force, such as tying a rope to the top of the pot and spinning it really fast to create centripetal force, much like what happens in a laboratory centrifuge.
