Common Problems of Roses
Rose bushes are generally pretty easy to grow, but sometimes they can be attacked by pests and diseases, or suffer from environmental issues.
Some small pests chew holes in the leaves or make great holes in the trunk, while others pierce and suck out plant juices. Larger pests usually take larger chunks out of leaves, flowers or fruits (Rose-hips) or remove them completely.
Diseases can be found on the aboveground parts of the plant or may be in the soil.
Roses suffering from environmental stress can be weather related, or how the plant is cared for.
