TIPS BACK TO TOP Watering - Inadequate irrigation is the biggest culprit of rose growing.
Roses love their water and sun.
Potted roses require far more frequent watering than do mature plants in the garden. As the plant matures in the pot and summer temperatures increase, a regular watering schedule has to be adopted. Fertilizing - As with soil mixes, each nursery has a preferred fertilizing program for their roses. In general, roses need their nitrogen to keep blooming and growing well. Minor elements needed most by roses are iron, zinc and magnesium.
