The yellow magnolia tree, with its bursts of bright blooms in spring is truly one of the most beautiful ornamental trees you can grow. While this gorgeous tree brings ample rewards in terms of visual appeal and fragrance when it flowers, it does take some time to reach its mature size. If you’re considering adding a yellow magnolia to your landscape it’s helpful to understand exactly how fast this flowering tree grows.
An Overview of Yellow Magnolia Varieties
There are a few popular varieties of yellow magnolia trees. The yellow bird magnolia (Magnolia x brooklynensis ‘Yellow Bird’) is probably the most widely grown. It was specially cultivated by the Brooklyn Botanic Garden (BBG) in 1981 to produce plentiful yellow blooms in late spring after the threat of frost has passed.
Another stunning variety is the yellow lantern magnolia (Magnolia acuminata ‘Yellow Lantern’). It bears 5-inch yellow flowers in early to mid spring The saucer magnolia (Magnolia x soulangeana) also comes in a yellow variety that typically blooms in March or April with cup-shaped yellow blossoms up to 10 inches wide.
What Factors Impact Growth Rate?
The growth rate of any tree including a yellow magnolia depends on several key factors
- Age of the tree – Younger trees grow quickly as they establish, slower as they mature.
- Species – Some magnolia species grow faster.
- Growing conditions – Sunlight, water, nutrients, soil drainage.
- Pruning and training – Pruning boosts dense growth.
- Climate – Warm weather and mild winters enable faster growth.
With ideal conditions, magnolias can gain several feet per year when young. But growth slows down as the tree ages.
The Moderate Growth Pattern of Yellow Magnolias
In optimal growing conditions, a yellow magnolia tree grows at a medium rate. Here’s what you can expect:
- First year – A nursery tree may reach 8 feet.
- Years 2-5 – Around 2 feet per year, up to 20 feet by year 5.
- Years 5-10 – Growth slows to 1-1.5 feet per year. It may reach 30 feet by year 10.
- 10+ years – Mature magnolias grow less than 1 foot yearly. Maximum height of 40 feet is reached in 20+ years.
So these trees take at least two decades to reach their full 40-foot potential. After the initial rapid growth when young, gaining height slows down considerably.
Caring for Your Magnolia Tree
To encourage your yellow magnolia to grow at a healthy pace, provide for its basic needs:
- Sunlight – Full sun is best. Afternoon shade can prevent stress in hot climates.
- Soil – Well-drained, acidic soil enriched with compost enables growth.
- Water – Water deeply 2-3 times per week while young. Reduce as it matures.
- Fertilizer – Apply balanced fertilizer after flowering in spring.
- Pruning – Prune damaged branches after flowering.
Meeting these care requirements will help your magnolia establish quickly and sustain growth over time.
Troubleshooting Slow Growth
If your yellow magnolia seems to be growing slowly, try these troubleshooting tips:
- Test and amend soil pH if needed.
- Ensure optimal sunlight exposure.
- Check for root competition from other plants.
- Improve drainage in soggy soil.
- Apply organic fertilizer if nutrients are lacking.
- Prune judiciously to encourage dense growth.
- Consider transplanting to a better site.
Enjoying Your Magnolia Despite Its Slow Growth
Even if your yellow magnolia is slow to reach maturity, the wait is worthwhile. This flowering tree will provide beauty in your yard for decades. Try not to impatience with its moderate growth rate.
Instead, enjoy watching your tree gradually transform from a sapling into a robust, flowering specimen. Appreciate its seasonal transitions across the years. The yellow magnolia’s leisurely pace is a small price to pay for its outstanding floral display each spring.
Fast-Growing Alternatives
If you can’t wait for a yellow magnolia to mature, consider these faster options:
- Choose a faster magnolia variety like the star magnolia.
- Buy a larger, mature nursery tree.
- Select another small ornamental tree like a crabapple.
- Plant in a container and repot to encourage growth.
But most gardeners find the yellow magnolia’s moderate growth rate worth the wait for its stunning blooms. Take the long view, and before you know it your patience will be rewarded with a gorgeous, golden-blossomed tree.
