What's killing my trees?

[Peasgood]

My next guess would have been phytophthora.

Only chemical i can think of would be if you could lay your hands on some Aliette, you wouldn't need much.

haha sounds like a good place to be.

 

I always open my bags once a week and just give them a little shake, also good to let fresh air in and check to see if it's damp enough, I've found mine tend to dry a little so always end up adding a few more drops of water.

Nearly 3 weeks now and no signs of germination? How long did your take to "hatch" ?

[Goaty]

Redwoods are prone to damping off. Usually damping off occurs in early seedling stage. But these can do it at a foot or so high. If I am right it's fungal. I will ask a nurseryman when I next see him. Maybe the old copper solution works?

keep the seeds in the fridge for 4 weeks mate.

 

after the 4 weeks take them out and try and keep them in a warm room about 20 Celsius.

 

check every day or two as they do germinate very quick.

what's the old copper solution?

 

I've tried a more drastic approach, I though I was fungal too, so I've clipped the dying branches off and treated with a rose fungicide, also let them dry out as much as I dare

 

have to see if I can control it and if it will cure it.

The old treatment was Cheshunt compound. You can't buy it now but there's plenty sitting on old shed shelves if you can find it.

I enquiries. It's thought it's the season. Phythopra is the big suspect. That adds the question when do they become resistant or do the weak simply fail in juvenile years?I will get my coat!

Have you thought about a mycorrhizal innoculate. It may stand a better chance if you innoculate the soil you are growing the species in with mycorrhizae that are native to that species, that may be the same story when it comes to saprophytic fungus which live within the cell walls of the tree and protect it from disease . Just a thought. I may be over thinking the situation😀

I've just read up on mycorrhizae, that's some clever fungi.

 

will give it a try and see how it goes

 

thanks for the info
