Don's Mailbag"

Gardena florida with yellow leaves:

Many people will suggest using Epsom salts  on gardenias but it could be cold damage at this time of year that has caused the problem & the leaves will become green again in Spring.    But they also love nitrogen so use a fertiliser such as chook poo and water it in. 

Sickly lavenders:

Lavenders don’t do well if they don’t have well aerated soil and lime.  Don suggested that the lavenders be replanted in a raised bed in a full sun area using 50% of the existing soil & 50% sand then adding lots of dolomite.

Bay tree with scale:

Bay trees are subject to scale and because of their height can be difficult to spray.  They can be grown in pots so they stay small then the scale can be sprayed with pest oil relatively easily.
