Can anyone give me THE REAL reason why new roots are stimulated whenever we change the potting media?
I don't think its a build up of salts because it happens even after the plant has been thoroughly flushed and leached for months with no fertilizer added at all.
Is the old mix inhibiting new roots in some way or is the new mix stimulating them?
Is there a build up of microbes which release some sort of inhibitor?
We have all seen it but I've not really read a convincing reason why it happens.
Rick, you might say that its a build up of K, but I'm still seeing it on seedlings recently repotted which have only been fed with the tiniest bit of blood and bone over winter (0%K). So why is it so???
Case #1 A compot of 4 bellatulums which did well over summer, then slowed down in autumn and stopped by winter. and thats what you would expect. then they were placed on bottom heat under lights and went into suspened animation until last week when I repotted them into thumb pots and within 3 DAYS!!!!!! new roots on three of them!!! The mix was basically the same.
Case #2 A compot of sanderianums....Same thing. #3 fairrieanums in small pots. Mix changed....well you get the idea...
If we can come up with the correct reason, we might go a long way in improving our successes.
It's keeping me up at night
Please exuse the drawn out post.
