toothache tree

The toothache tree (Zanthoxylum americanum) typically does not need much water and does best with infrequent, deep watering. Water when the soil appears dry, about once every week to 10 days. However, during dry periods, you may need to water more frequently or even add a few inches of mulch to help retain soil moisture. The soil should always be moist but not waterlogged, so avoid over-watering. Give the tree an extra drink during hot summer days and during the first few weeks after planting.

The toothache tree (Zanthoxylum americanum) grows in areas with full sun or partial shade, and should receive at least 6 hours of sunlight per day if possible. Morning sun is best, and light dappled shade in the afternoon will reduce the risk of leaf burn. When the tree is grown in full sun, it needs extra water as the strong light encourages it to use up moisture quickly. This species of tree requires consistently moist, well-drained soils and is not tolerant of flooding or drought.

Toothache tree (Zanthoxylum americanum) requires light pruning in early spring. This will help promote bushiness and promote new growth. Pruning should be done lightly, removing only small branches or stems no more than 1-third of the current growth. If you need to remove a larger stem, cut it just above a node (the place where a branch meets the trunk). Remember, pruning too much can cause damage to the tree and reduce the amount of new growth. It is also important to sanitize pruning tools before using them on the toothache tree to avoid spreading any disease.
