Biodiversity . . . .


Increasing the biodiversity of our garden is an excellent defense against pests. Whenever we simplify an environment by spraying an insecticide or by growing only one kind of plant, problems can get out of hand. Create an environment that is more complex by planting a wide range of plants.
Once established, invasive exotic plants displace our Native plants and are difficult to eradicate.  Depending on the circumstances and species, eradication methods may involve chemical sprays, manual removal, biological controls or a combination of these methods.
The control of invasive plants is vital to the preservation of our delicate ecosystem and the survival of many native plants as well.  (Over 80% of the world’s plants growth in tropical regions.  1/3 are in peril of extinction.)
Soap-based herbicides dehydrate leaves by cutting through their protective layer of cutin. These types of organic herbicides work best on young weeds but are only a temporary setback to well-rooted perennial weeds. To minimize damage to other plants, spray young weeds when temperatures are above 70 degrees, on a sunny, dry, non-windy day. Be aware that repeated applications of a product containing acetic acid (which is very strong vinegar). It can lower the soil's pH, making it more acidic.

Education leads to awareness. 

Research invasive plants and remove them when possible.
