"Terraponics" for Houseplants

Most plants transition from soil to hydroponics without incident. But for some  . . .  it's not so easy.


Some plants struggle after converting to hydroponics.

Why?

Converting soil plants to hydroponics means forcing the plant to convert it's soil roots to water (hydroponic) roots. This can be a challenge for some plants. 

  • large plants that have been growing in soil for years -in the same pot have complex root systems and have a hard time converting.
  • plants with thin, delicate roots have difficulty recovering because removing the soil often damgaes their roots (think Boston Ferns)
  • and then there's the group of plants that are simply stubborn. For whatever reason they simply refuse to convert existing roots to hydroponic roots. They insist on growing new ones instead. This takes time and stresses the plant - often sending it into "survival mode".

Unfortunately, many of these plants never recover.

No worries - we have a solution!

It's called "terraponics".



What is Terraponics?

"Terra" means soil. "Terraponics" means growing plants in a hydroponic system without removing the soil from their roots.

Originally designed in Euorpe for outdoor planters, terraponics is becoming increasingly popular with many indoor plants.

With terraponic growing, the entire root ball (soil included) is packed into a bed of hydroponic pebbles, leaving the plant’s roots undisturbed.

This eliminates the stress some plants experience when soil is removed from their roots. 

Notice how LECA pebbles surround the root ball on all sides in the illustration on the right. These pebbles wick moisture up to the plant's root ball gently and evenly from the reservoir at the bottom of the planter. At the same time new (stronger) water roots grow out into the pebbles.


Eventually new water roots will replace old soil roots - and then your plant will start enjoying all advantages of hydroponic growing!
