Indian Bean Tree in January: monthly care

Prune your Indian bean tree during dormancy between November and February, ideally in late winter just before growth resumes. Pruning at this time minimises sap bleeding and allows you to see the branch structure clearly. Catalpas require very little routine pruning once established; they naturally develop a broad, rounded crown without much intervention. Use sharp bypass secateurs for stems up to 2 cm diameter, loppers for branches up to 5 cm, and a pruning saw for anything larger. Always cut just above an outward-facing bud or back to a main branch, avoiding stubs that invite disease. Focus on removing dead, damaged, or diseased wood first. Then take out any branches that cross or rub against each other, as wounds from friction can become entry points for infection. If two branches compete for the same space, remove the weaker or more awkwardly angled one. Young trees benefit from formative pruning in their first three to five years: select a strong central leader and remove lower side branches gradually to raise the crown to your desired height, typically 2–2.5 metres for clearance beneath. Remove no more than one-third of the crown in any single year. Mature catalpas rarely need pruning beyond the removal of dead wood, though you can reduce overlong or wayward branches to maintain shape if necessary. Avoid heavy pruning, as catalpas respond with vigorous, weakly attached regrowth. If a large branch must be removed, make the cut just outside the branch collar to promote proper healing.
