Q: My lamium, which is planted in various locations around the house, is blooming beautifully, however, the leaves are starting to show pink-colored spots on them. This happens yearly, no matter what kind of soil is used.

This is an interesting question but hard to diagnose from that description. It could be a number of things. We may be able to rule out soil acidity and alkalinity problems as you say it occurs in all locations in your yard but not completely.

It may be nutritional, as an excess of phosphorus and potassium have been known to cause a purpling on leaves in other species.

It may be fungal if the spots look like eyes with a definite iris and a yellow halo.

It would be best to contact a garden centre and get an expert to look at fresh specimens.
