|I have 2 Tipuana Tipu trees that were planted about 4 years ago. About 75% of the pods seem brown and crisp and it looks bony with not much foliage. I have never fertilized them. They get watered about 3 times a week. They just do not look well. What could be wrong with them?
|Tipuana tipu grows 25'-40' tall and about 30' wide. It has a broad, flattened crown that is wider than high, but can be pruned to make a denser, narrower, umbrella-shaped crown. A member of the legume family, the tree roots fix nitrogen in the soil and rarely, if ever need fertilizing. They grow best in full sunshine, in average soil. If your soil is strongly alkaline, it can affect the health and appearance of your trees. The trees need to be watered regularly during the growing season and a slow, deep soak is better than frequent, shallow watering. Instead of watering 3 times a week, try watering once each week, applying water to the soil slowly so it has a chance to percolate down and thoroughly wet the root mass. If things don't improve, have your soil tested. If it's very alkaline, the test results will recommend some steps you can take to lower the pH and make your Tipuana trees happier.|
