Watering your roses can be a tricky thing. It is one of the most important aspects of taking care of your roses. Roses need almost as much water to stay healthy as people do. Of course there are quite a few things that must be considered before you water your roses. They are as follows:
Like people, roses need more water during the hotter weather than during the colder ones. Heat makes the soil dry faster and the roses get “thirstier”.
Keep in mind that even during the rainier times, roses still need to be watered with fresh water because rain alone cannot provide the right amount of moisture for your roses.
You want to water your roses in a manner that goes deep enough into the surrounding soil so that it reaches the roots. Try going approximately 45cm deep.
You do not want to water the petals directly or the canes because it can cause fungal disease in your roses.
To help you lower the risk of your roses getting diseases, mulch is a nice way to keep the soil moist, without allowing all of the fungal problems that too much moisture can cause.
Watering your roses in the morning also helps to dry the dew off of the leaves.
Once your roses are fully established, you should water them once a week. You should do it twice a week if its in the hotter months.
