Roses-there are so many-where to start. The “new” knockout shrub roses
have had some difficulty making it through our tough springs. We get
very warm, the roses (and other plants) think it’s spring, and they
start growing. Then we get a very cold spell. This is what is killing
our plants. We need to add plenty of mulch to plants, to keep them cold
in the spring. So if your “knockout” roses are planted in rocks, move
the rocks away. The rocks warm up the plant too early in the spring. The
newest recommendation on knockout roses is to plant them deep. So plant
the graph union 6” below the soil line and add mulch. Knockout roses
give so much flower power for the summer-don’t give up on them!
Remember roses like fertilizer. We recommend
incorporating 2 gallons of mushroom compost into a new rose. If you have
an existing rose, add rose fertilizer as package directions. Also, add a
package of soil moist to the planting hole. This will help retain
moisture during the hot summer.
