How Much To Water Roses

Roses like a lot of water during the growing and blooming season. But this doesn't mean give them a small amount every day. Like with watering other plants, it is better to water deeply rather than just a little bit at a time, so that the water can fully penetrate the roots. Just sprinkling them with the hose is not enough.
Let the hose give your roses a full, thorough soaking. A good four or five gallons worth of water per rose bush is a basic rule of thumb. Depending on how much rain your garden gets, a deep watering once a week is usually enough even in drier parts of the country. If it is extremely hot and dry, perhaps every four days or so.
Avoid watering during the heat of the day in direct sunlight. Early morning and late afternoon are the best times to water.
