The Garden Corner
Spider mites, aphids, thrips, oh my! Sadly, along with fall colors comes an invasion of these pesky insects. And trust me, when it comes to bugs, things can go south real fast! Fall’s warm weather, often times referred to as “The Indian Summer”, creates the perfect condition for these destructive creatures to explode overnight. Before you know it, there could be a full fledged war happening in your backyard. Luckily I have some tricks up my sleeve to keep these bugs at bay.
Now there’s a few things to keep in mind when it comes to repelling insects. This first thing to remember is that you’ll never be able to kill every single bug. Not to worry though, plants are able to tolerate a few insects here and there. Secondly, it’s highly important to be mindful of bees. The rule is: When flowers are present, there’s likely to be bees present. That’s why fall is an optimal time to spray for pests, as most plants are in a somewhat dormant state waiting for the winter rain.
When the bugs attack, the first thing I’d recommend is Neem oil. This organic pest repellent is made from the seeds of the Neem tree, and available at most nursery centers. Neem oil works by covering the insects’ breathing holes, and is also effective against leaf fungi on manzanita and toyon. Next on the list are soap sprays. I would suggest a simple soap spray made of potassium salts, which like Neem oil, smothers the bugs’ breathing holes. Lastly is Bacillus thuringiensis. This spray works exclusively on caterpillar insects like the ones that eat oak trees, and should only be applied in the evenings as it breaks down in the sunlight.
I hope this gave you a bit of insight on how to prepare for Fall’s creepy crawlers. Until next time, happy gardening! If you have any questions, please contact me at: gritlys@gmail.com
