I have 3 types of Molimba which done really well throughout the summer. They are now looking very hard done by over the last month and wonder if they should be cut back and if so when would be the best time to do so. I am new to gardening so not sure of these things.
Molimba is a brand name of the Paris daisy or marguerite, Argyranthemum frutescens.
It is a tender plant for greenhouse use or outdoors in summer and early autumn.
Frost can kill it outright or at least make it look very shabby.
It is easily grown form cuttings taken in late summer and overwintered as small plants indoors in a greenhouse, porch or sunny windowsill.
The existing plants may be trimmed back in spring but may also be too far gone at this stage.
