Summer brings rain - rain brings insects and grubs. Look on the leaves at night time and pinch off. Use some chemical sprays or organic mix. Any general fertiliser.

There is no planting guide for Rosella for United Kingdom. Probably not warm enough to grow.

Do I cut back my rosella plant after fruiting.? Mine seems to be dying, not a single leaf on it.

I started a tray of roselle in June an I'm planting now in July. Is it too late? I know that roselle blooms when the days start getting shorter, how does this work after the summer solstice?

Don't know your climate but after frosts I would think. It likes warm climate.
