thoughts on restoring a burried yew

Why thy sugar solution ?

Application of sugar solution provides an immediate supply of carbohydrate to the roots. This can stimulate fine root growth as well as increase fungal and microbial populations in the rhizosphere. More mycorrhizal fungi = improved nutrient and water uptake.

so having read the report, by what means is the sugar solution 'injected' into the rooting area ?

more worm and invertebrate activity as a result ?

I'm guessing it was injected using something like a 'Terravent'. If the soil around the Yew tree is heavily compacted you'll need to address that before adding any amendments. If it's not too compacted (maybe it's a sandy soil?) then you may get away with just making some drainage holes with a fork or corer and watering it in using a watering can.

Hi Paul, did Glynn allude to whether the application of additional carbs in the rhizosphere attracted the mycelium of non-beneficial fungi, like Armillaria for example?

Hi David,

 

Yes, In fact I asked him that exact question. He seemed to think that Mycorrhizal fungi would colonise the soil quicker than fungi such as Armillaria. However, I would like to see the evidence behind that statement. I imagine that a healthy rhizophere i.e. rich in beneficial fungi and bacteria could have an antagonistic effect against fungi such as Armillaria. Hence why Trichoderma seems to be a possible control.

 

We got onto the subject following a demonstration of the new 'Arb-ex' compressed air lance. As you know Glynn has researched the effect of 'air-spading' on Armillaria colonisation of tree roots and root collars. Ted Green has always been sceptical of 'air spades' because he thinks they destroy the mycorrhizal fungi colonies. That prompted me to ask which fungi come back first.

Thanks Paul

 

Will be interesting to follow any related research over the next few years.

 

 

Note to self, get more soil samples taken !
