Controlled-Release Fertilizer for Healthy Plant Growth

Our controlled-release fertilizer is a premium, high-quality formula designed to deliver nutrients gradually and efficiently over time.

Each fertilizer granule is coated with a protective resin. This coating allows water to penetrate slowly, dissolving the nutrients and releasing them into the soil in a controlled and consistent way.

This product provides a feeding period of up to 100 days, with a balanced 15-9-12 (NPK) formulation—ideal for young, actively growing trees and shrubs. Nutrients are released evenly during this period under typical growing temperatures of 20 to 25°C.

How Temperature Affects Nutrient Release

The release rate increases as temperatures rise, matching the natural growth cycle of your plants. This helps ensure your trees and shrubs receive more nutrients when they need them most.

Satisfied customers

The trees arrived as expected. They were all in excellent condition and exactly the size we ordered. We'll definitely be placing another order for next spring. All we can do for this year is hope the deer don't get too fond of them.

Sylvie Trépanier

I am very satisfied with the services and products of TreesOnline.ca. I am a biologist by training and I know Quebec's flora very well. I consider the selection of species offered to be exceptional. I received my trees on time from the delivery company. The packaging was neat and the trees were in excellent condition. All that remained was to repot them for planting later.

I'm delighted with the quality of the plants and the excellent service. Everything is impeccable from start to finish. I've paid much more for disappointing plants before. At Arbres en ligne, everything is simply perfect, and that's coming from a gardener! A truly wonderful discovery, and this certainly won't be my last order!
