Regal Pelargonium prefer a clay pot and plenty of calcium, so hard water is ideal for watering rather than rain water which will be softer.
Regal Pelargonium do not require as much cutting back and require a slightly higher winter temperature than zonals.
Never allow Regal Pelargonium plants to dry out completely as the roots will seal and blackleg will kill your plant.
Deadhead old flowers frequently and feed regularly with high potash so that they will perform as well as your Zonals.
Crimped edges on some petals add to the allure.
