We heard through the grapevine of the internet that there is a new and rather odd-sounding plant hack on the block. The hack in question? Using a boiled old potato to help an orchid plant thrive.
So if you have an old potato that you’re not going to be needing then this trick claims you can turn it into a natural plant fertiliser for your orchid. Technically, this method doesn’t necessarily require the potato to be an old one. So even if you’re just boiling some potatoes for your dinner, then you can use the remaining water to give your plant a boost.
Because it’s this miraculous, nutrient-rich juice that apparently does wonders for your orchid, according to plant experts. So here’s how to use old (or new) potatoes to keep your orchid blooming and how it works.
Potato fertiliser hack for orchids
We bet that you didn’t think boiling potatoes is a part of how to take care of an orchid. To be fair, neither did we. This natural plant care hack has taken us by surprise, too.
‘Potatoes provide potassium and phosphorus, which are both essential to orchid flowering and growth,’ starts Petar Ivanov, Fantastic Gardeners' plant and gardening expert.
Fiona Jenkins, garden expert at MyJobQuote.co.uk, the UK’s leading trades matching site, adds, ‘Boiled potatoes are commonly used as a cost effective, homemade fertiliser for orchids. Other kitchen ingredients including eggshells and molasses are also utilised by experienced orchid growers.’
But Steve Chilton, garden expert at LeisureBench, warns that it’s not exactly a conventional method how to water orchids and help them grow. ‘It has been said that boiled potatoes can be used as a natural fertiliser for orchids, although this isn't necessarily seen as a "conventional" method, so if following this advice I always recommend keeping an eye on your orchids to notice any negative changes, and adjust as needed to ensure they stay healthy.’
But if you do decide to give this hack a go, this is what you need to do.
How to fertilise orchids with potatoes
‘Boil your potatoes with the skin on, as this is where the majority of the nutrients can be found,’ Fiona explains. ‘You can grate or chop the potatoes first, to help release more of these nutrients during the cooking process. Drain the water into a jug or jar and let it cool. It’s this water that you use to fertilise your orchid.’
Steve adds, ‘It's important to let the water completely cool down after boiling, then add to the orchids as you would with normal water. I would recommend diluting the starchy water with normal water as this will ensure that there's not too high of a concentration of nutrients, which could actually damage the orchids instead of benefit them.’
The world of plants never ceases to amaze us. Boiled potatoes for orchids – who would have thought?!
