It sounds like a gimmick — leave out deoxyephedrine cubes into your houseplant pots or else of using a watering can . But this offbeat method has been around for over 50 years , and for some people , it ’s a go - to technique — especially for watering orchids .
So , is it a good thought ? Is it dependable for all your works ? permit ’s look at the history , what the experts say , and what science has to volunteer . you could also find additionalhouseplant lachrymation summit here .
Watering With Ice Cubes
The earliest mainstream reference of watering houseplant with ice cubes date back to the 1960s . One name that stands out in the origin story is Thalassa Cruso — a British - American gardening expert , television personality , and bestselling author . She had a democratic gardening show in the U.S. and was a frequent Edgar Albert Guest onThe Tonight Show with Johnny Carson .
In her horticulture book , Making Things Grow : A Practical Guide for the Indoor Gardener(1969 ) , Cruso compose :
“ To debar a day-to-day shower of pee down your sleeve from carry a watering can overhead , try using ice cubes flat from the frosting bucket . Put them like a rhombus necklace around the lip of the pot . They will dissolve slowly and the soil will take over the moisture evenly , and those maddening trickle will be nullify . Also , no matter what you reverence , the ice cube will not hurt the plants . ”
Back then , houseplants often hung from the ceiling in macramé hangers . cosmetic , yes , but cunning to water without make a mess . Cruso ’s point to simply drop in a few ice-skating rink cubes on the grease control surface made the line of work easier and far less prone to wasteweir . Still , not everyone was convert it was best for the plants .
Early Skepticism
By the seventies , ice regular hexahedron tearing was being dismissed by some garden writers as a craze or even serious .
Frances Tenenbaum , in 1974 , pointed out the restriction , joke that using sparkler cube until you get the moisture just powerful would only suit someone enjoy a very long cocktail hour — something we ’ll circle back to in a minute . Another writer bluntly called it a “ horticulturally dangerous fad . ”
Enter the Orchids
tight - forward to the 2000s , and ice cube lachrymation experience a second lifespan — this time in the orchid gangway .
A U.S. company plunge “ Just Add Ice ” orchids — specificallyPhalaenopsisorchids — with a simple sales talk : just add three chicken feed cubes per week . That ’s it .
This removed the guessing and anxiousness for orchid newbies . No indigence to worry about over- or under - watering . You could even sign up for weekly electronic mail reminders : It ’s ice cube time !
It work . The product took off — and reignited the debate .

The Ice Cube Backlash
Tropical works fan were horror-struck . How could freeze down cold chalk cubes perhaps be serious for warm - loving orchid ?
inhuman damage in plants is a real concern , especially for tropical species . shuddery injury can occur even at temperatures above freeze . So the idea of dropping literal chalk into a pot sounds counterintuitive — if not downright harmful .
But Wait—Is There Any Science?
Yes . In 2017 , a squad from Ohio State University and the University of Georgia issue a field inHortSciencelooking into this exact take .
They testedPhalaenopsisorchids watered with ice cubes and compare them to I watered with room temperature water .
The finding :
In short : no harm done .
They did note that control soil wet ( I usea moisture meteror my digit ) and adjusting the routine of ice cubes would be ideal . But as a general method acting , it was ok .
Not Everyone’s Convinced
Of course , one cogitation ca n’t resolve everything .
critic pointed out that :
That does n’t mean the results are invalid , but it ’s fair to say we still do n’t live everything .
Is It a Good Idea for Other Houseplants?
Possibly — but we do n’t have any research on that .
unlike plants have unlike source systems and growing media . What works for barque - based orchidaceous plant mix may not translate to your pothos , ceriman , or gamboge Sir Herbert Beerbohm Tree in potting soil .
Concerns about cold exposure aside , if you have houseplants now you get laid their water needs vary .
Using the same “ three frosting third power per week ” principle for all houseplants is wishful thinking . Just think of how much water you use now to good water your plant and what the combining weight would be in chicken feed block . That ’s a flock of icing cubes!And would the melted ice even penetrate deeper root ?

So… ShouldYouUse Ice Cubes?
Here ’s the little reading — for something like a small potted orchidaceous plant ? perhaps . Everything else ? No .
It seems deoxyephedrine regular hexahedron do n’t harmPhalaenopsisorchids the manner some once reverence , but that does n’t mean we can just flip a few cube on every houseplant and call it a twenty-four hour period . Houseplant care is more nuanced and needs change with the seasons — even indoors .

Our Verdict
If water with shabu cubes simplifies handle for small orchidaceous plant — great — but it quickly get visionary for other houseplant .
For example , I use 2 cup ( 500 ml ) for my little lemon yellow tree ( 8 inch pot ) each time I water . That would be 16 ice cubes for just one plant ! They would n’t even agree on the uncommitted soil surface so I ’d have to bring them in shift — waiting hours for each batch to melt . So no time saving or assurance the mystifying roots get body of water .
If flow pots are hard to get to , a goodwatering can with a really long , narrow neckis my top pick . And , as inconvenient as it can be , a good uncompromising mini step ladderwith sturdy hand supports may be required to access hanging plants .
Long term , it really helps to understand what your plants demand . These tips showhow to create a custom houseplant care planto streamline everything .
