I'm not really a rose fan. They are lovely as cut flowers and all, but there are others I prefer. And as part of a flower garden, they require a lot of effort and pesticides and rose food and such that in my opinion is really not worth it. However, the mint green 50s style house Adam and I are renting has a whole bunch of roses.
And now that I am basically responsible for these roses I feel like I should do my best to take care of them-mostly because I am afraid the old lady who lived here all her life would likely haunt us if I let them die. Which left me with a dilemma- how do I get rid of aphids and black spot without using pesticides? Surprisingly, it was inexpensive and super easy. I found these recipes on a website about organic gardening:
Against aphids and whiteflies:Garlic Oil Spray
10-15 cloves of minced garlic
2 tbsp. mineral oil
600 ml water
1 tsp. liquid dish soap
Soak garlic in mineral oil for 24 hours. Strain garlic out and add 600 ml water and 1 tsp. liquid dish soap. Mix thoroughly and spray rose plants with the solution. This solution will also kill spider mites and whiteflies.
Fungicide for Mildew and Black Spot
1 tsp. baking soda
1 liter water
1 tsp. soap flakes (I used organic goat soap given to me by one of my clients)
Dissolve baking soda in 1 liter of warm water.
Add soap flakes to help solution cling to leaves. Remove infected leaves from plant and then spray top and bottom of remaining leaf surfaces to control spread of the disease.
2 tbsp. mineral oil
600 ml water
1 tsp. liquid dish soap
Soak garlic in mineral oil for 24 hours. Strain garlic out and add 600 ml water and 1 tsp. liquid dish soap. Mix thoroughly and spray rose plants with the solution. This solution will also kill spider mites and whiteflies.
Fungicide for Mildew and Black Spot
1 tsp. baking soda
1 liter water

Dissolve baking soda in 1 liter of warm water.
Add soap flakes to help solution cling to leaves. Remove infected leaves from plant and then spray top and bottom of remaining leaf surfaces to control spread of the disease.
Only apply these sprays every 5-7 days.
Both of these sprays worked really well after just one application! You may be asking yourself why I care about not using pesticides- I have lots of reasons, but here's one of them. Mostly I just don't believe in screwing with the environment so I can look at pretty flowers. Try it out and let me know what you think.
