Rose Care

Agriserve has always been there when I needed them to be. They work very hard to keep my citrus trees healthy. They are easy to work with and are always informative when I have a question. They are on time every time I have scheduled work with them. They are nothing but a positive business with the customer in mind. I would not hesitate to recommend them. Brian Montez Rialto U.S.D.

Rose Care


Whether you've planted the roses on your property yourself or you've inherited them through the purchase of your home, your roses should be the jewels of the neighborhood. Keeping them healthy will help them look their best. At Agriserve, we have developed a program to address key issues roses encounter throughout the year and help your beauties thrive.


The following is our calendar of treatment:

January
  • Treat with horticultural oil (a.k.a. dormant oil)
  • Fertilize (after roses have been pruned)
  • Apply systemic insecticide for aphid prevention
