Roses grow happily in pots if the pot is a generous size, for example:
A pot at least the size of a 15 litre bucket will happily grow a rose bush for up to three years if you use a premium potting mix. We recommend peat based potting mixes. Osmocote slow release fertiliser pills added to the potting mix will slowly break down & release it’s nutrients over an 6-7 month period.
Watering is the key to success and during the height of Summer, twice a day is often needed. Include a liquid fertiliser (Seaweed / fish based) once a month in the watering can at the recommended application.
There are a number of smaller growing bush roses and miniatures that do exceedingly well in pots. Standard roses look amazing growing in pots too, especially underplanted with your favourite annuals. These make a great statement either side of entrance ways into gardens and on decks.
