Q.Can You Water Knockout Roses Too Much
Can you water Knockout Roses too much and about how much should you water them? I’ve been watering them every evening and the blooms are dying. They are in full sun. How can I get them to bloom better?
If you are watering them every evening it is likely too much. I water my roses every 5 to 6 days. But I do keep an eye on the soils moisture using a moisture meter. I stick the probe into the ground in three places around each rosebush and see what reading I get. If it shows wet to medium/moist I know I can wait a couple more days at least. Usually with Knockout roses new buds are coming on as the old blooms are dying so the wait for more is not long. If you are not seeing the new buds coming on, then I would suggest feeding them with a good organic based rose food. You do not want something real high in nitrogen as that will give you lots of foliage and next to no blooms.
