January Rose Care

by Witherspoon Rose Culture Posted January 04, 2024

Applying dormant spray is one of the best things you can do for your rose bushes during winter. We recommend using a  Dormant Spray Oil mixed with a Contact Fungicide.

Why Use Dormant Spray?

  • It is a desiccant that will dry up the remaining leaves on your bushes. This is especially helpful in climates that have warm winters in that it will help the bush drop its leaves and go dormant.
  • The Dormant Oil will smother any spider mite eggs or other detrimental insect eggs and larva that are overwintering in your rose bushes and garden mulch.
  • The Fungonil, or contact fungicide of your choice, will dry up any fungal spores that are still lingering on your plants and in your garden mulch.
  • By eradicating fungal spores and insect eggs, it is less likely the first rain of the season will splash the trouble-making spores and eggs back onto your bush.

How to Use Dormant Spray:

  1. Mix up 3 Tablespoons of Dormant Spray, 2 1/4 teaspoons of Fungonil, and 1/2 teaspoon of Spreader Sticker with 1 gallon of water.
  2. Spray bushes AND the mulch surrounding the roses.
  3. Wait 2 weeks and apply for a second time if blackspot, downey, or spider mites were an issue during the previous growing season.

Is Neem Oil a good dormant spray for this purpose?

Neem oil is a common product some folks use. You will want to check the label to see about using it with a contact fungicide. The Hi-Yield product called Dorman Oil is our number one choice.

Yes, where to purchase the dormant spray and fungonil? Also, when to order several fragrant cloud roses for planting in Elkin, NC? Thanks, Bill Blackley

We sell both Dormant Oil and Fungonil online and in store. We are accepting orders now for roses. Are you wanting to have bareroot roses shipped?

Hi- where would I buy both the dormant spray and the fungonil? I have the spreader sticker from the mixytre that I purchased from you (Captan, Thiomyl, Bondie Systemic Insecticide, spreader sticker) for the “usual” insect control. Please advise and thanks so much!
