Briefly: Easy steps how to use Neem Oil for garden etc.
1. Pure Neem Oil will retain its potency much longer if stored at about 40° F in a low light area such as a refrigerator.
2. Do not mix anything with Neem oil until you are ready to use it. Mix only the amount of Neem oil you will use in 4 to 6 hours.
3. A new batch of Neem oil, water and a little soap (according to the label) should be mixed each time you are going to spray.
4. The soap (dishwashing detergent) is used to help emulsify the oil. If no soap is used the Neem will not mix into solution with the water and spraying will not be effective.
5. Spray the complete plant including the top of the potting media. Spray benches, walkways and any surface over which an insect might travel.
6. A mixture of 1 oz. to 1 gallon of water should be used for spraying. A weaker solution may be used as a maintenance spray. It is impossible to gie a definite schedule for spraying, however a “close eye” will help each person to adjust a timetable to maintain clean plants. You will probably not have to spray as often with Neem as with toxic insecticides.
How to use Neem Oil?
Use 1 ounce to 1 gallon of water + few drops of dishwashing liquid. Spray every six months. The beauty part of using Neem oil is that you don’t have to wear protective clothing or special breathing equipment and there are no sickening odors. Neem oil does have an odour, best described as ‘kind of like onion soup’. However, the odor only lingers for a short time. When using Neem oil mix the amount to be used within four hours. Neem is very biodegradable and starts to break down quickly. If it is kept in the refrigerator at approximately 40F the shelf life is extended. As any organic oil, it will turn rancid. How soon will depend on the storage temperature
How does Neem get rid of insects?
Most insects die shortly after spraying. Those remaining become sterile and do not reproduce. It is better if you can prevent the insect from eating the plant, than to let them eat the plant and then die.
