Science has confirmed that along with stones to the underside of your flower pots can truly hurt the crops. So why are we nonetheless doing it?
An equivalent to me, you’ve likely heard to your total life – at the very least your gardening life – that it is best in order so as to add small stones, gravel, objects of damaged ceramic pots, or fully totally different filler to the underside of your containers earlier than planting. The reasoning is that it gives better drainage to your crops because of it helps the water drain sooner by way of the pot.
It sounds low value, appropriate? Nevertheless plainly stones inside the underside of the pot truly gradual drainage and will hurt your crops. Scientists have confirmed it.
Actually, they busted this gardening fable greater than 100 years to this point and loads of occasions since then. Nonetheless somehow, this essential actuality hasn’t entered the collective conscience of dwelling gardeners – we’re nonetheless throwing every type of factors into the underside of our flower pots. I used to be accountable of this too till I stumbled all via the analysis on the Yard Professors web internet web page on Fb.

Evaluation present that in a pot, water doesn’t shortly cross from soil to stone
Scientists have demonstrated that water doesn’t merely swap between a unbelievable textured provides like soil and a coarser provides like stones. Additional notably, water could very properly be very gradual to cross the world between the 2 gives. So the coarse gives on the underside of the container gradual water drainage, making the soil additional liable to show into waterlogged and probably drown your plant’s roots.
“The exact actuality is, when water transferring by way of a soil reaches a horizontal or vertical interface between fully fully totally different soil varieties, it stops transferring.”
Why this occurs: gravity
Fairly than water freely transferring down by way of the the soil and all via the stones, water resists crossing the barrier between them. That’s on account of the water contained in the better layer is being pulled upwards by the dry soil and the crops. This offsets the outcomes of gravity, which may in each different case pull the water by way of the stones. The water builds up contained in the prime layer till it’s oversaturated, and solely then is water contained in the soil launched into the layer under. The oversaturation of the soil poses a menace to your plant’s roots and could also be why your container-grown petunias didn’t survive the season typically.
“It’s a fable {{{that a}}} layer of gravel (inside the underside of a person pot) beneath the soil improves container drainage. As an alternative of additional water draining instantly into the gravel, the water “perches” or gathers contained in the soil merely above the gravel. The water gathers till no air house is left. As shortly as all of the obtainable soil air house fills up, then additional water drains into the gravel under. So gravel inside the underside does little to maintain up soil above it from being saturated by overwatering.”
So the next time you pot up your crops, merely add soilless potting combine and nothing else, And naturally, make sure there are good drainage holes contained in the pot.
