Identify my false acacia

Tree growing 2 to 30 m tall, with fissured gray bark, with imparipinnate deciduous leaves composed of 9 to 19 ovate leaflets, spiny, and white flowers in pendulous clusters. Native to America and very well acclimatized in most regions, in rich and clayey soils.

Plant my false acacia

You can plant robinias in any type of soil. Plant preferably in winter, in bare roots or in mound. Dig a hole deep enough, twice as large as the root ball, without mixing the layers of the soil. Plant a solid stake at the bottom of the hole, on the edge, inclined to the prevailing winds. Cut the root hair - the fine roots that looks like hair - to balance the volume of roots and foliage. Plant without burying the boundary between trunk and roots of the tree, putting the soil layers in the same order you removed them. Tamp the soil around the roots with your foot, so you do not leave a pocket of air, and attach the stake to the trunk with a suitable extensible link. Form a hollow in the soil and water abundantly until you fill it.

Water my false acacia

Water regularly and generously for several weeks after planting. After, you only have to worry about watering in case of severe drought.

Prune my false acacia

The pruning of the robinia is not essential, but it will define its appearance in the long term. It is necessary to regularly prune the low branches to obtain a trunk, in the long term. The first years it is also necessary to remove the branches which cross and those which return towards the interior.

Unprop my false acacia

After two years, remove the stake, which has no use anymore and may damage the bark.
