What can I feed my Hardenbergia as their leaves are turning yellow?

We live in the Adelaide Hills and planted 3 Hardenbergia about a year ago. All three are doing well especially one which have a lot of purple flowers. Two plants are not growing so well and have yellowing leaves.

Hi Annie,

If the leaves are yellowing all over then they may be requiring nitrogen. Apply a small quantity of Dynamic Lifter. Check the leaves to see if there are any mites present which may cause the leaves to be slightly mottled. Some webbing may be on the back of the leaves. If you do see any eveidence of mites apply some Yates Nature's Way Vegie & Herb Spray Concentrate which is bio degradable and non- residual.
