back to top Questions and Answers This page is currently being RE-CONSTRUCTED. Starting in January 2008 a listing of questions and responses will be provided in this location and will be added to each month. This listing will a shortened version of the full listing in the member's section which will be searchableWe apologize for the delay in the re-organization of this page but are confident that the full results will be worth waiting for. Q. Do I need to pull the mulch back from the plant when fertilizing? A. It depends on what type of mulch you are using. If pine needles are used, you do not need to pull mulch away from the rose base. Wood-chip mulches, however, mat and may keep fertilizer away from the ground and plant. In this case, temporarily move the mulch away to reveal some clear space before applying the fertilizer. Q. How do I know when I have Chilli Thrips on my rose bush? A. Chilli thrips will attack any color of bloom. Coastal thrips will usually only attack light colored blooms (whites, yellows). The first sign will be NEW buds that show black on the outer pedals and then completely turn black and die. Next, look for new (purple) leaves that crinkle up and don’t look healthy. Once this occurs, die-back on the bush will become noticeable, and should be removed. Spray with Conserve SC or Conserve Naturalite (this form is less expensive, but you do use a larger dose; it is, however, better suited for the small rose garden). Q. Is there any ‘organic’ solution to spraying for Black Spot or Thrips? A. This time of year, when the temperatures are lower, you can move from your chemical spray program to the use of oil-based sprays. One that several of us are using is Organocide, an organic broad-spectrum insecticide and fungicide consisting of edible fish oil (92%), sesame oil (5%) and lecithin (3%). It is available in a sprayer container ready to spray (cost: around ). It also comes in a concentrated version for use in your own sprayer. Our Partners MRT and Wayne Hibbs Farm and Garden carry the product. For maximum success, remember these rules:
