Diatomaceous Earth Pest Control for Irises

Treat your iris garden with diatomaceous earth food grade and you will control the borer pests and also grow healthy plants that will produce beautiful blooms.  

For healthy irises with beautiful blooms follow my pest control tips.

For the past week, I have been cleaning up my gardens by removing the oak leaves that fell from the trees at the end of March, the first week of April.  When I got to my iris gardens I noticed that the wet leaves that covered the tubers had attracted borers.   

The borers will eat the tubers and weaken the health of the plant and if the iris is left untreated the borers will eventually kill the irises.  I acted quickly to this infestation of pests by treating the garden with diatomaceous earth food grade.

When it comes to treating my garden for pests I prefer to use a natural substance that will not harm humans, wildlife, and pets.  Over the years I have had excellent results with diatomaceous earth when I use it for yard and garden pest control.

Instructions

Remove the leaf debris or mulch from your iris bed on a day when there is no wind. 

Fill a powder sugar shaker with diatomaceous earth food grade and take safety steps to protect yourself from inhaling the dust by wearing a fine particle ventilator mask.

Loosen the dirt that surrounds your iris tuber and then shake the diatomaceous into the loosened soil. Cover the dust with soil. This treatment will kill the pests in the soil also. 

Shake the diatomaceous earth food grade all over your iris garden. This treatment will prevent above-the-surface garden pests from eating your tuber or iris leaves.  

Spring showers will cause the diatomaceous earth to enter the soil that surrounds the irises. This is good as it will continue to kill off pests in the soil that feed on iris tubers.  

Watch your garden for any signs of borers.  If you view a yellow streak in your iris leaf or insects crawling on or around your iris tubers then retreat the garden with the diatomaceous earth food grade.  

Notes from Sgolis

Keep your iris garden free of weeds and debris.  As this will enable the iris plants to take in the nutrients from the sun and your plants will be healthy and produce large flowers.
