So that brings us to the newer styled web pots.
We have them in all sizes from little 75mm ones right up to massive 50 litre sized.
By adding a three clawed hanger to the pot they can swing away up in the branches as a pot but still have a near 100% airflow through the pots.
A classic wet dry cycle of watering suits these pots. A heavy flooding watering and then a complete drying out between.
Knowing when to water your orchids is never a matter of picking a day each week and simply every third day, its a feel you get,sort of like a an orchid water empathy!
I have always felt tank and or rainwater is better for your orchids. The chlorine in mains water MAY effect the microbial life in the orchid compost, thats the microscopic beasties that break down the bark and other organic matter in the compost that lightly feed the orchids.
Our mains water is held in giant 25000 litre tanks and allowed to settle for a few days. Chlorine turns into oxygen and common salt after a few days.
Its only a theory and may not be anywhere near true, but somedays you can actually smell the chlorine in the tapwater.
So how do you repot the orchid when its crowded the webpot?
Simply move it up a few sizes and plant pot and all into the larger webpot. EASY!
To divide, just cut the orchid up using a new large breadknife. Saw away and the webpot just gets quartered up as well.
The rule to remember is "more orchids are killed by overwatering than underwatering"
