Roses are high-maintenance flowers and may wilt without the proper care. Wilting, marked by droopy leaves and blooms, is most often caused by either a lack of water or overwatering, too much sun or lack of sun. Fungal or insect infestations are another cause of wilting, and potted roses may wilt if they've outgrown their container.
Look on the bottom of your flower pot to make sure there is a drainage hole. If there is no hole, remove your plant and drill a hole, or transplant your roses to a different container. Cover the bottom with a bit of gravel before replacing your plant.
Inspect your plant for insects or mould. If you see any, apply a fungicide or insecticide to your roses (use a rose-specific product according to the directions on the package), and prune off infested canes below the point of damage. Prune crossing canes to eliminate future mould growth.
Touch the soil around your roses. If it feels dry and doesn't stick to your finger, water your roses until water comes out of the drainage hole at the bottom of your flower pot. If your plant is very dry and the leaves are turning brown, submerge your pot in a basin of water and leave it there until air bubbles stop rising to the top. If the water is moist, don't add any more water.
Monitor the sunlight your roses are getting. If your roses aren't getting enough sunlight, move or transplant them to a sunnier spot. During the fall or winter, your roses may not get the six hours of direct sunlight a day that they need. In this case, supplement sunlight with UV light. If your plants are getting too much sun, move them to a less sunny spot.
Gently remove your roses from their pot and inspect their roots. If their roots seem too large for their current container, transfer them to a larger pot.
