Kernel soap against aphids on roses
There are already some tips for the fight against aphids, here is my tip, which I have tried myself and has worked to 100%.
Make a mixture of about 40 g (about half a piece) of curd soap and 1 L of water, the piece is dissolved in about 2 hours in hot water.
If the water should then be too creamy, add some water, stir well or shake, place in a spray bottle and spray the roses in the evening at best.
The next morning the aphids (for me it was the little green beasts) are black and dead. The roses are washed off with plenty of water, with a shower, and all aphids are gone.
