Littleleaf Linden
The Littleleaf Linden (Tilia cordata) is a small tree with an upright oval shape and a neat, attractive crown. It is native to a wide area throughout Europe and it grows rapidly. The leaves are oval and dark-green, with small hairs on the upperside. In summer, the tree produces fragrant yellowish-green flowers which hang in clusters. The fruits are small, rough nutlets which appear in late summer and provide food for birds and squirrels.
The Littleleaf Linden will need to be watered regularly, particularly in dry weather, for at least the first year or two after planting. It is best to apply a deep, slow-release watering. After the tree is established, it will only need supplemental watering during extended periods of drought.
The Littleleaf Linden prefers full sun but can tolerate partial shade. Young plants should be protected from strong winds because the foliage can suffer from wind burn. This tree can also cope with urban pollution.
The Littleleaf Linden can tolerate very cold temperatures, down to -5 degrees Fahrenheit, and can also cope with high temperatures up to 95 degrees Fahrenheit. It does not do well in extended hot periods.
The Littleleaf Linden prefers moderate humidity levels that are between 40 and 75%. Elevated humidity levels may cause fungus problems in the leaves and stems.
The Littleleaf Linden prefers an organically-rich soil with good drainage with a pH of between 6.0 and 7.5. Add composted organic matter such as manure or compost to the soil before planting.
The Littleleaf Linden can be fertilized in late winter or early spring with an all-purpose fertilizer such as 10-10-10. Apply the fertilizer around the soil, taking care to not let it touch the trunk of the tree. Follow all manufacturer’s instructions for application rates and frequency.
The Littleleaf Linden is generally resistant to pests, but spider mites, aphids, and Japanese beetles may cause it some damage. Check the tree regularly, especially when new growth emerges in the spring and summer. An insecticidal soap or horticultural oil may be used to rid the tree of pests.
Repotting is not necessary for the Littleleaf Linden, but containers should be inspected for proper drainage and the soil should be changed every two to three years. The appropriate potting mix should be used, such as a mixture of compost and sand.
Pruning the Littleleaf Linden should be done when the tree is young in order to shape the top into an attractive crown. As the tree matures, dead limbs should be removed as needed. Pruning is best done while the tree is dormant.
Mulching is useful to retain soil moisture and suppress weeds. A mulch between 2 and 4 inches in depth of organic material such as bark, cocoa bean hulls, leaves, or pine straw can be applied to the soil around the tree.
The Littleleaf Linden can be propagated by taking root cuttings from an existing tree. Take cuttings in winter and store them in soil, sand, or vermiculite until spring. Plant the root cuttings in moist, well-draining potting mix in individual containers. Place the cuttings in a bright location with temperatures of 65–75 degrees Fahrenheit.
The Littleleaf Linden has strong wood and generally does not need support to stay upright. If the tree is near a road or an area of strong wind, it may need to be supported with stakes or guy-wires.
The Littleleaf Linden does not have a specific rest period. It benefits from being pruned in the winter or early spring before it starts putting out new growth and flowers.
The Littleleaf Linden is not toxic to pets.
