Insect Control

Pest and weed control in the garden has changed dramatically over the last few years. At Greenland we focus our effort on providing environmentally friendly options.

Recent government regulations have removed many familiar garden products from garden center shelves. These regulations are imperative in preventing overuse of chemicals, and go a long way in protecting both ourselves and the many beneficial animals in the garden. Both experts and gardeners are needing to familiarize themselves with new, safer controls.

Eco Friendly Insect Controls
Chemical Based Controls


Prior to using any products in the garden, please ensure the insect or disease has been properly diagnosed. Greenland does provide a diagnostic service free of charge - simply bring in a sample of the insect or damaged plant material, and our staff will provide you with a diagnostic form to fill out. Please note that as our service is complimentary, our horticulturalists are often overwhelmed at the height of the garden season. Diagnosis may take up to 1 week.

Valuable information can also be found in the What's Bugging portion of our site. Feel free to forward an image of any plant damage, insect or disease to: tina@greenlandgarden.com

Horticultural Oil

Simply mix with water and spray on branches of dormant trees/shrubs to smother insect eggs that have overwintered. Can also be used in season, however dilution must be increased.


Apple Maggot Traps

Traps contain an attractant that lures the fly to a sticky apple shaped trap before they lay eggs.
