My Jackmanii clematis has always been hardy and very prolific but this year it started out with yellow leaves. I read some of the older threads and took advice to apply 2 Tbls. Epsom Salts in 2 gallons of water and pour around the base of the plant. I then topdressed with composted cow manure. I did this exactly 1 week ago and I am wondering if this is enough. Is there something else I can do to help it?
