Hiya folks,

Hope you are all enjoying the glorious weather! Have been lurking for
the last few weeks as have had no questions and have been unable to
answer anyone elses. Well all that is about to change I'm afraid.

I have some hollyhocks in the garden, only about six of them. I have
noticed that the leaves have some sort of disease, there are masses of
bumps on the underside of the leaves and I mean absolutely loads. The
leaves are literally covered with what looks like loads of eggs,
although I don't think they are eggs, they are also an orange colour.
The plants don't seem to be getting very tall but they do have buds on
which look fairly healthy. Does anyone have any ideas or know what
this is? Thank you in advance.

Hollyhocks (and others of the mallow family) are prone to rust, which
looks like little pustules of orangeness. I don't think there's anything
you can do about it. Take off the worst affected leaves and dispose of
them.
