I’ve actually never heard of this gardening strategy ever before. But this topic is growing all over the internet, pinterest and other websites. This caught my interest. Some might object, but this way of watering indoor plants will avoid mess inside your house.
Need to keep plants cool and watered throughout the day during the summer? Try placing a layer of ice cubes on top of the soil.
Over-watering is one of the most common causes of houseplant demise, but a simple solution may reside within your freezer.
Instead of hydrating plants with a watering can, which can result in messy H20 overflow, try placing a large ice cube (or a few small ones) on the soil once a week. Jillian at I Am a Homemaker says the slow-melting ice gives roots and dirt enough time to absorb the water properly. This method is also great for hard-to-reach specimens (like hanging plants) and orchids, because their roots need to be well drained, without any water pooling at the bottom, according to Amanda Gutterman at Gardenista.
“Some people swear it even keeps orchids alive.”
