Ive experimenting with some new nutrients. Ive read in a few places about people using chicken manure - so i got some and gave it a try. To start it seemed OK. I will keep using it on the lawn and vegetable beds.
BUT. A magnolia i was rescuing died suddenly midway through opening its flowers. I was not pleased.
I then dropped a small piece of chicken manure pellet in and observed.
The lesson learnt is that i must test new additives before i put them on to avoid unexpected results.
For species that like alkaline conditions this is fine. There are plenty of trees down south grow in the chalk. I would recommend avoiding this for acid lovers like pines and magnolias / azaleas.
