| USUALLY a plant will not need to be repotted for at least a year or two after you purchase it - if it was well taken care of. I like to repot mine soon after flowering because I like to know what the condition of the entire plant is (including roots) and I want my similar plants in like media. If it is in bark - when the bark begins to get soft/mushy and act like little sponges - and doesn't dry out normally - then the roots will stay soggy and begin to rot - so time to repot. Other media have other signs. Sphag will break down too - become hard when dry and very mushy when decaying - it will need replacing much more often than bark. Hope this helps. Mike |
