Summer is in full swing with victory gardens, community gardens and flowers in bloom. Even here in Florida with the humid summer heat plants still need tending and care. Did you know that according to a survey, almost a third of all American households intended to grow food this year? That’s almost a 20 percent increase over last year!  Recent studies are also suggesting that exposure to friendly soil bacteria could improve your mood just as effectively as using antidepressant drugs. To quote Mohandas K. Gandhi, “To forget how to dig the earth and to tend the soil is to forget ourselves.” Don’t take for granted the fresh fruits and vegetables that are put on our tables. Growing a garden for food brings to light a healthy curiosity for what is safe and non-toxic for humans and the environment. To reap the benefits of a garden we must ensure the health of the soil and plants, while deterring unwanted pests.

So how does neem fit into this?

For more than 4,000 years, the mighty neem tree has been providing healthy, safe and therapeutic solutions for people, pets and plants. The United Nations declared neem the tree of the 21st century, and neem is currently cultivated in more than 80 countries. Neem (Azadirachta indica) is fondly referred to as “the village pharmacy” and has been used by millions of individuals as a botanical panacea for health and well-being, and for protection and prevention against insects. Neem leaves are classically stored with grains and beans to protect them from insect infestations. Worldwide, neem oil is one of the more widely used and safe bio-pesticides, used in organic agriculture. Not only is it beneficial as a pesticide, it enriches the health and vitality of the soil, plants and farms and is also safe for bees and other pollinators.

Natural amendments and garden treatments like neem oil offer multi-faceted benefits over single active ingredients. When we use single active ingredients as treatments in our garden, we may throw nature a curveball for a short while and deter pests and disease, but there are often unwanted side effects to this method. Mother Nature is intelligent and will eventually outsmart a single active ingredient and create “super bugs” or “super bacteria” to combat these simple complexes. When we utilize botanical allies such as neem oil we are utilizing thousands of diverse molecules, each of which offers slightly different actions. Chemical pesticides and fertilizers are transparently being linked to countless diseases for humans, pets, bees and the environment.

Neem oil is easy to use in the garden. Just mix about ½ ounce of quality organic neem oil to one quart of warm water and an environmentally safe dish washing detergent to emulsify the oil in a spray bottle. To apply, spray both on top and below the leaves so that rain doesn’t immediately wash away the oil. Use the remaining mixture as a soil drench to benefit earthworms while discouraging undesirables. I have formulated a product called Neem for the Garden that accomplishes this end easily.

Neem oil is one of those little “natural” secrets that can make a huge difference when gardening while ensuring a greener and more sustainable outcome. Even indoor household plants can benefit from its protective properties. Happy gardening!
