I,ve potted some with so so roots & it does seem to take a few months for the plants to adapt.Once new roots start they seem to really thrive.What if the root system isn't the best?
I just use what is readily available which is a product called "Hydroleca" , which is just basically a topping aggregate.For Paphs , Phrags ,Phals i add a little charcoal.For the plants that are supposed to not like their roots constantly wet i add more charcol.The charcoal doesn,t "wick" very much so the top of the medium stays drier.What kind of media works best? Do you do different media for different kinds?
Prime Agra seems to be the medium people rave about but i haven,t tried it(can,t get hold of it).
Yes remove all the medium you can as it will rot quickly when kept constantly wet.When you pot into s/h you don,t "firm" the medium down.You just tap & shake the pot to spread the medium around the roots so little chance of damaging roots.I soak the medium in SuperThrive to help the shock of repotting & only water with no fert for a few weeks .How do you pot the orchids without damaging the roots? I'm assuming you want to get ALL the bark off?
The local garden centre(i suppose something like your HD stores).Where do ya'll get you supplies? Online somewhere?
Just remember to fill the bottom of the pot with medium to slightly above the drain holes so that when you pot the plant it,s roots are not in water.
My Phals have roots below the drain holes now after a few months & seem to
have no problems.
I tried a sacrificial Phal in s/h after doing a few weeks of seeing how well the medium wicked & deciding how high the holes in the pot had to be.The plant was cheap (about $17) & it has been in bloom for nearly 4 months(19 flowers) & still looks absolutely superb.
