Wellingtonia and coast redwood waterlogging issues

[APC]

Hi,

 

I have had problems with a high water table, which we initially thought was a burst service pipe. Water had been rising from an old drain amongst some redwood plantings and had consequently waterlogged a large proportion of the root zone. We had attempted to keep the water moving by digging a shallow trench to get it away to a nearby drainage ditch. Once this was in place, it ran for a month after. We had had out contractors to check for leaks as I refused to believe that the water from the drain wasn't a leak. We have loads of old service lines under the park from various layers of history and I guess it is possible that it is an old drain and the water has come from elsewhere but has found the pipe that runs to this. It stopped running about a month after the heavy rain stopped.

 

The problem is, the 2 adjacent trees, a wellingtonia and a coast redwood, are now yellowing off throughout the foliage, getting worse every day. I am hoping it's not too late to save them. We are on clay, would we benefit from airblasting the root area and applying a mulch? I have read that 2 weeks is pretty much the limit of a tree surviving waterlogging. I'm hoping though that the water being kept moving as much as possible might have stalled this.

 

Any advice would be pucka please.

Can't help too much here but was the water clean or foul ? In other words was it storm water or sewage / contaminated in any way . ? This could affect your chances of saving them

Hi, I think it was storm water. It didn't smell at all. If it was a burst pipe, it would have been fresh water.

Well , in that case you have every advantage given the circumstances. I hope you can save them . We recently took down a medium red wood due to the old honey fungus . Dead as a do do it was .
