Should Employ Ice Cubes to Irrigate Your Plants?
This Core Dilemma
Countless houseplant succumbs to excessive care; dousing them each time you look proves lethal. Using ice cubes to provide water pledges slower and better-regulated hydration. But, can it really deliver?
This Popular Method
Position a couple of ice blocks atop the potting mix. The idea posits while the ice dissolves, it slowly dispenses water, providing the roots a chance to take up it and averting waterlogged soil.
Examining the Practice
This trick functions best for little planters and varieties sensitive to excess moisture, for instance orchids. However, most of warmth-loving houseplants are averse to cold temperatures. A plant's roots developed for heat, and freezing water can shock or injure them. The surrounding climate plays a major role in the hack's effectiveness: in a warm environment, the ice will melt almost instantly, providing scant advantage, whereas in a cool spot it may linger too long, lowering the temperature of the roots and reducing absorption. Make sure to confirm ice cubes are composed of clean, clean water and do not place them directly against plant stems or exposed roots.
The Test
This was tested on a Phalaenopsis. Two cubes each week kept the roots nicely damp without sogginess. In contrast, employing the same method on a Calathea caused discoloration at the tips of the leaves, a telltale indication of chill damage.
The Final Verdict
This frozen water method might be effective for Phalaenopsis, but it is not ideal for many tropical houseplants and hinges heavily on ambient temperature. Therefore, this hack won't be advised; tepid water given slowly remains the safest method to thoroughly moisten your green companions.
