Joann,
I use 1/2 cup of sudsy Amonia to 1 gallon of water, and a squirt of dish soap. Then I soak my plant cuttings for up to 30 minutes depending on the cutting type. The harder the cutting, the longer I soak, I'd recommend 30 minutes for woody cuttings.
Amonia is not only a disinfectant, but is actually a nutrient for plants also, and helps to give them a little something to "chew on" while rooting. I've noted that many cuttings root faster, usually within 2-3 weeks.
1/4 cup of Amonia in a gallon of water and a squirt of dish soap sprayed on leaves is good for foliar feeding too. it's the same thing to a plant as the ingredient urea found on fertilizer packages. (test on a leaf, and flower first and wait a few days for adverse reactions before spraying on an entire plant) It gives plants a boost ! They love it!
The smell will temporarily Help to repell bugs, and wild life too.
Some plants may be sensitive to 1/4 cup/gallon, and need a weaker solution.
Always use sprays only in the evening, never in the sun.
To avoid sun scald.
