How to Grow Laburnum
Growing laburnum trees can be highly rewarding. With their graceful form and stunning yellow blooms, laburnums make exceptional ornamental specimens in the home landscape. By providing the right conditions and care, you can successfully grow these beautiful trees.
Selecting a Planting Site
Choosing an appropriate planting site is the first step in growing healthy laburnum trees. Consider the following factors when selecting a location:
Sunlight Needs
Laburnums thrive best in full sun. Look for a spot that receives at least 6 hours of direct sunlight per day. Morning sun is especially beneficial. Dappled shade is tolerated, but too much shade will reduce flowering.
Soil Requirements
Laburnums prefer fertile, well-draining soil. The ideal soil pH is neutral to slightly acidic. Avoid planting laburnums in very wet or compacted soil. Amend the soil with compost or other organic matter to improve drainage before planting.
Room to Grow
Allow enough space for the laburnum to reach its mature size. Laburnums generally grow 15-20 feet tall and 10-15 feet wide. Give the tree at least 15-20 feet of space on all sides to prevent overcrowding.
Planting Laburnum Trees
Spring is the best time to plant container-grown laburnum trees. Follow these tips for proper planting:
- Dig a hole 2-3 times wider than the root ball. The hole should be only as deep as the height of the root ball.
- Carefully remove the tree from the container and loosen any encircling roots.
- Place the tree in the hole and backfill with the soil. Firm the soil gently around the base.
- Water thoroughly after planting and apply a 2-4 inch layer of mulch around the base.
Aftercare
Regular watering is crucial while the laburnum is established. Water young trees 1-2 times per week during dry periods. After the first year, established laburnums are quite drought tolerant.
Caring for Laburnum Trees
Proper care and maintenance will keep laburnum trees healthy and support maximum flower production. Key aspects of laburnum care include:
Watering
- Water regularly during the first year after planting. Provide 1-2 inches of water per week.
- In subsequent years, provide supplemental water during droughts. Deep weekly soaking is better than frequent light watering.
Fertilization
- In spring, apply a balanced, slow-release fertilizer following label directions. Avoid over-fertilization.
- Top dress with compost or manure each fall to nourish the soil.
Pruning
- Prune laburnums soon after flowering to shape and maintain the plants.
- Remove any diseased, damaged or crossing branches.
- Shorten overly long branches to encourage dense growth habits.
- Remove suckers and watersprouts that emerge from the rootstock.
Pest and Disease Control
- Laburnums have few serious pest problems. Aphids, scale, leaf spot may occur.
- Promote vigor through proper care. Remove affected parts promptly.organic insecticides if needed.
With the right growing conditions and care, laburnums will flourish and delight the garden with their colorful floral display each spring. Be sure to cite them appropriately and attend to their seasonal water and nutritional needs. Some pruning for shape and plant health will allow laburnums to fully showcase their graceful elegance.
Propagating Laburnum Trees
Gardeners who already have a laburnum tree may wish to propagate additional plants. Laburnums can be propagated by seed or by cuttings:
Propagation by Seed
- Collect pods when they turn brown and seeds rattle inside. Air dry pods further and remove seeds.
- Sow seeds 1⁄4 inch deep in fall or stratify seeds by cold treatment prior to spring planting.
- Germination often takes 2+ seasons. Transplant seedlings when large enough to handle.
Propagation by Cuttings
- Take 6-8 inch tip cuttings from new growth in early summer. Strip bottom leaves.
- Dip cut end in rooting hormone and plant in potting mix. Place in a bright area, not direct sun.
- Most frequently to keep humid. Rooting takes 1-2 months. Transplant young plants to the garden.
With patience, new laburnum specimens can be grown from seeds or cuttings of existing trees. This allows gardeners to reproduce treasured plants.
