Replanting after removal due to Meripilus

[swinny]

What are peoples thoughts on re planting in similar position to a tree removed due to meripilus? it has a large host range of tree's it effects so I would presume the list of suitable replacements will be small?

 

Stump was ground out and hole filled back with grindings. Meripilus seems to be showing still on some surface roots and seems to be attacking a now close proximity tree. This tree is within approx 5-6' from the one that was removed and ground out. 

 

Is it possible that grinding out the stump on the first tree removed approx 12-18 month ago disturbed/damaged some of the roots of the second tree allowing merip a hold on this tree? Be interesting to think if this was the case... if the stump was left and not ground out it may not have spread to the healthy tree?...

 

Does merip need actual physical damage to a tree to get in?

 

Does it remain in the soil for years? I've heard and seen re fruiting for consecutive years. 

 

Many thanks for any info.

Anyone any ideas? Thanks

Damage is needed, but the common death of a tap root may be enough. From what I know it takes a few years of establishment of infection before surface fruiting occurs. Grinding may not have been your cause.

 

It doesn't reinfect every year, the fruiting is seasonal on established decay sites. I would guess the spores persist in soil for years though. A healthy replacemente shouldn't get infected but you might want to steer clear of Fagaceae and Tiliaceae and Ulmaceae. I would have thought Acereacea or Rosaceae would be suitable replacements.
