Questions and Answers

This page contains a shortened listing of questions and responses taken from our monthly Bulletins. The full listing of questions can be found in the searchable bulletins available through the Member's Menu.

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 donít look healthy.

Q. Is there any Ďorganicí 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 $22). 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:
  1. Do not spray with oil-based products when temperatures are above 80 degrees for most of the daylight hours.
  2. Three hours before spraying, give the plants a good watering.
  3. Spray in the evening or early morning before sunrise. This gives the residual spray time to dry before direct sunlight exposure.
  4. Spray top & bottom of foliage.
