Thuja Green Giant -Fastest Growing Hedge Plant

Thuja Green Giant -Fastest Growing Hedge Plant

As more people are moving into houses with smaller lots, and closer neighbors, they're looking for the fastest growing hedge plant that can be used to create "instant" privacy.

Thuja Green Giant is your fast-growing answer! I've traveled the country, and this new hybrid that was introduced to American gardeners about 15 years ago (that's still "new" for a conifer) from the National Arboretum in Washington, D.C. , grows an amazing 3' per year once it becomes established. How do you get your plants to grow this fast?

Here's a secret growing tip to fast growing thujas!  Every April 15th (the dreaded tax day) I fertilize with 2-3 tablespoons of Osmocote slow-release fertilizer scratched into the top 2 inches of soil at the base of each plant. Then, I water at least 1" per week from spring through late fall. This guarantees you'll see rapid growth of 3' or more per year.

Can you prune Green Giant thuja? Absolutely! If left unpruned, thuja Green Giant will form a graceful pyramidal shape 8' wide and 40'-50' tall. They respond wonderfully to pruning in early summer, after they've had their spring flush of growth. I've seen them planted a mere 18" apart, and kept to a tight 6' tall surrounding a formal rose garden.

Thuja Green Giant is extremely versatile, and thrives in sandy or clay soil. I've seen it growing in hot/steamy Atlanta, Georgia all the way up into our location here in Western Michigan! You can't ask for a better fast-growing privacy hedge plant. Looking for the perfect 8' tall evergreen privacy hedge plant?  Look no further than thuja "Emerald", which has all the wonderful attributes of Green Giant, but shorter, and only 3 feet wide.

Consider planting long blooming Knock Out roses and/or ornamental grasses at the base of your thujas for the finishing touch.
