hydroponics question
I have been growing my dendrobiums in expanded clay balls for quite some
time now with fair results. I am wondering if I should keep some kind of repotting schedule, as I do in more conventional media, because there is no breakdown in the clay. I do change the water occasionly of course. Please give me your experiences. |

Please give me your experiences. I don't grow Den. I have Paph, Phrag, and Cymbidium in Semi-Hydro. Which is a clay pellets in a pot with 3 holes along one side. (See www.firstrays.com for more details) We repot when the plants (Phrag) climb up out of the pot, get too big for the pot or the roots cause the pots to crack (cym).

Te primary reason to repot when using organic media is to rid yourself of
decomposing material, which packs easily and traps lots of water in the "macropores" between the media particles, both of which combine to reduce air flow to the root system, setting you up for root rot. A decent ceramic medium will exhibit none of those symptoms, so the repot is neither essential, nor advisable. -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies, Books, Artwork, and Lots of Free Info! ..

Over time some orchids tend to become rootbound. The spaces between
the pellets get filled up with roots so there is less room for air, water, and access to the fertilizer by the growing root tips. If your plant is starting to slow down or it seems like it is always dry a repot and root trimming can perk it up again. When you pot-up enough pellets usually fall out to open up the rootball but sometimes you have to get the clippers out and hack away some of the roots and pellets. I try to dig a cone in the middle of the rootball after snipping off the bottom inch of roots and pellets. henry wolf wrote: I have been growing my dendrobiums in expanded clay balls for quite some time now with fair results.
