Bonide's Rose RX Systemic Drench protects entire plants, including new growth, against insects and diseases. Simply measure, mix and pour around the base of roses and shrubs, or sprinkle directly over the top of entire flowerbeds. Rain or watering does not wash away, provides long lasting protections of up to 6 weeks. One quart will treat up to 16 roses or other shrubs, or approx. 200 sq ft of flowerbed.
Fill a bucket or watering can with the appropriate amounts of concentrate (add first) and water (add last).
Single Plants: Slowly pour as close to the base of the plant as possible, being careful not to get on leaves.
Flowerbeds: Sprinkle over the tops of the plants and cover the entire area.
NOTE: The Flowerbed solution is diluted with more water than the Single Plant solution to ensure safety to plant leaves when sprinkling over the top.
When finished, rinse the bucket/watering can with clean water and pour onto treated area
HOW MUCH TO USE
2 fl.oz. (4 TBSP) in 1 quart of water treats 1 plant
2 fl. oz. (4 TBSP) in 2 gallons of water treats 12 sq. ft.
Azaleas. Camellias, Rhododendrons, and Other Shrubs
1 fl. oz. (2 TBSP) in 1 quart of water per foot of plant height
FOR BEST RESULTS
Begin using this in the spring when plants are actively growing.
Reapply every 6 weeks for a total of 3 applications per year. In areas where disease occurs frequently and the soil is sandy, the application interval can be shortened to 4 - 5 weeks for a total of 4 applications per year.
Ensure the it gets down into the rootzone by:
1. Pulling mulch away from plants to be treated.
2. Building a well around individual plant.
3. Pouring the drench solution slowly to allow the soil to absorb it.
Keep rose, flower, and shrub beds clean. This minimizes harborage sites for diseases and insects.
I am a professional horticulturist, and I also maintain as close to an "organic" garden as I can. This is THE ONLY product that I use in my garden and in my work. Since it is a systemic, the plant's roots suck it up and it doesn't get sprayed all over the place like powders, oils, sprays and dusts. I only treat the affected plant and it's close neighbors. Also, it controls insects, fungal infections and bacterial problems as well. Some versions of it feed the plants too. As with any pest control, FOLLOW THE LABEL! The only time this did anything negative was when I accidentally poured it ON TOP of a just-planted Balloon Flower (it was burnt to a crisp the next day.) I will never use anything else. This product is amazing and I only need to use it once in late May and once in mid August on my rose bush.
What are the mixing ratios for Bonide Rose RX Systemic Drench Concentrate?
The mixing ratios are as follows: ROSES: 2 fl oz (4 tbsp) per quart of water for each plant, FLOWER BEDS: 2 fl oz (4 tbsp) per 2 gallons of water to treat 12 sq ft, AZALEAS, CAMELLIAS, RODEDENDRONS, OTHER SHRUBS: 1 fl oz (2 tbsp) per quart of water to treat each foot of plant height. You can find all of the mixing instructions on the product label which we have linked in our answer but which is always available on our website on the Bonide Rose RX Systemic Drench Concentrate product page below the picture of the product.
What is the application ratio for single plants when using Bonide Rose RX Systemic Drench Concentrate?
Page 2 of the instruction booklet says "Note: the Flowerbed solution is diluted with more water than the Single Plant solution" but your ratio guidance on page 3 doesn't give any guidance on the ration for "Single Plants." Does anyone know what this ration would be?
From page 4 of the product label for Bonide Rose RX Systemic Drench Concentrate: FLOWER BEDS: 2 fl oz (4 tbsp) per 2 gallons of water to treat 12 sq ft. You are not just treating the plant itself but are also applying to the surrounding area of the plant so that it will be absorbed by the roots. The best way to determine this would be to measure the square footage of the area you need to treat to determine the smaller amount needed and divide accordingly. IE if only 6 square feet is needed to treat you would use 1 fl oz in 1 gallon to treat this 6 sqft area.
Can Bonide Rose Systemic Drench be used in a thermal fogger?
No, Bonide Rose RX Systemic Drench is meant to be applied as a soil drench only around rose bushes and other ornamentals so the root system will take up the product systemically. It is not intended for use out of a fogger.
I used Bonide Rose RX Systemic Drench on my roses, do I need to spray them also?
Does using the Bonide drench replace the need for spraying my tea roses? Prior to using this for the first time last week, I was using Fertilome 3 in1 spray routinely every 7 to 10 days. Since I applied the drench, I was not certain if I should apply the 3 in 1 spray also. I would appreciate your advice.
Since roses are so delicate and this is a new product for us we recommend you contact Bonide directly. You can reach Bonide by calling 315-736-8231.
Bought for black spot on potted roses. I see it says on for use in pots. Any way I can dilute to use in pots?
Bonide's Rose RX Systemic Drench product label specifically says " Do not use on plants grown in pots, flower boxes or other containers" so we can not give you directions on this type of usage as it is an off label usage. You can contact Bonide directly and they may be able to better help you in this situation. You can reach Bonide by calling 315-736-8231.
