Plant my indian bean tree
Plant your catalpa in ordinary draining soil, in full sun or partial shade.
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 indian bean tree
Water regularly and copiously for a few weeks after planting if you did it late. After, you should not have to care anymore, except during droughts
Prune my indian bean tree
The catalpas support pretty well pruning, you can trim them each spring right above ground to keep them small and dense with very large leaves.
For a tree habit, we advise not to keep side branches at the bottom of the trunk during the first years.
Otherwise, a few years later, they will suffer from the shadow of the upper branches.
Once it is adult, remove or prune the dry branches before they fall, every two years.
Unprop my indian bean tree
After two years, remove the stake, which has no use anymore and may damage the bark.
