Zelkova

We love this relative of the elm for the quality of its foliage, and its wide and elegant shape.
Common name : Zelkova
Scientific name : Zelkova spp.
Family : Ulmaceae
Category : Trees
Type of plant : Perennial
There are 6 species of Zelkova, all native to Asia, and Z.carpinifolia and Z. serrata are cultivated in Europe. We like its majestic habit with oval leaves resembling those of the elms. They grow a nice orange tint before falling. In spring it carries separate male and female flowers, in the form of a simple grouping of stamens or pistils without petals. The fruits bear a single core coated with dry flesh, faceted, the size of a raspberry.

Identify my zelkova

Zelkovas are trees of first magnitude, which can reach 35 meters in some species. Some dwarf cultivars of zelkova measure 1 to 5 meters. The leaves resemble those of elms, they are oval, oblong or elliptical, crenated or toothed - with rounded teeth -, alternate, slightly asymmetrical. They take a nice orange hue before falling. In spring, the tree has separate male and female flowers, in the form of a simple group of stamens or pistils without petals. The fruits have a single core coated with dry, faceted flesh, the size of a raspberry.

Plant my zelkova

Plant in cool, moist, drained or heavy soil, in the sun, not too close to a building. Planting bare roots is only done in winder where as you can plant trees with a root ball and in a container until spring. With bare roots, carry out a treatment (shorten the roots and soak them in a mixture of soil and compost). Plant in a hole that is about 20 cm bigger than the root ball, gradually put the crumbled earth back by regularly tamping down around the roots. Water after planting with at least 50 liters of water that you will pour into a basin formed around the trunk. A tilted stake planted in the hole will be useful against strong winds as long as you don't forget to remove it after 2 year and that you use a supple attachment.

Water my zelkova

In the first month and in case of drought, water abundantly but not too frequently, so that the roots will fetch water deeper. Water thoroughly, until the soil is full and forms a small puddle around the tree.

Prune my zelkova

Prune your zelkova with the intention of airing it, not shortening it. Once a year in February-March, eliminate dead branches, those that come back inwards and those that cross.

Unprop my zelkova

Two years after planting, remove the stake.

Check on my zelkova

Zelkovas are sensitive to Dutch elm disease that can cause damage, but their natural resistance allows them to survive. If you see traces of leaves gnawed between April and September, it is linked to the attack of a beetle, Galerucella luteola. This is serious only for young trees.
