How many tablets of CoreTect do I need to use for a 7' tall ficus hedge for whitefly prevention?
A continuous hedge runs along the entire side of my 100" property, and it is about 2-3 feet wide. My neighbor's front hedge shows a serious white fly problem, and I want to use this as a preventative measure. How many tablets should I apply and at what spacing in the ground?
You will need to take a look under the hedge and treat each root system individually instead of treating the hedge as one plant. According to the CoreTect product label, you will need 3 tables per foot of shrub height, so for a 7 ft plants you will need 21 tablets for each plant. Release of active ingredient is dependent on presence of adequate soil moisture. For best results, irrigate the plant after treatment, and ensure that the plant receives regular irrigation for at least 2-3 months after treatment
