London, United Kingdom

I sent this question to you yesterday and got your reply very quickly. However, my husband didn't recognise the email address & thinking it was spam deleted it!! Would you mind resending your reply. With many thanks.
I have two hibiscus plants in my garden - Hamabo (pink, red eyed) Both plants have a number of buds although nowhere near the number I've seen on the blue variety. About 50% the flowers never come out but just stay as buds and then wither on the plant or fall off. There are 2 large trees in the garden next door adjacent to the hibiscus and we have 2 trees in our own garden (one the other side of the garden & one nearer) but the hibiscus are exposed to quite a lot of sun/light during the day. Can you tell me what the problem might be or are they just poor specimens. I've had them both around 6-7 years.

One other question. I always plant bizzie lizzies in a small bed which borders the patio and usually they give a wonderful show but this year they've been really disappointing, have never come to anything much and now seem to be going limp with no flowers at all. They are well watered as we have a watering system installed. What do you think might be the problem. I'd be grateful for your thoughts/suggestions/ideas.

Thank you.
