Can I use phosacid on a grafted flowering gum around 6m tall & if so what strength.

Is growing in sandy soil but in a garden situation.Seems to have collar rot at the graft. Most new shoots and leaves dry out before maturing. Tree had one flower this year but none last year and leaves are sparse.

Answer: Hi Daphne,
Yates Anti Rot can be used to control root rot diseases such as phytophthora and pythium. It is applied to the plant foliage at the rate of 5 ml per litre of water. It can be used on native plants such as flowering eucalypts.

You may need to re apply the spray 4 weeks later.
