It is about 7 years since we planted it and we bring it indoors for the winter. I was told to hose off good, trim back about 25% and water with solution of one teaspoon dish soap to 1 gallon water per gal. of water mixture along with systemic insecticide, which I have been doing.
The pot size is 20" with good drainage and in direct sunlight. The tree hardly blooms and recently has been having yellow leaves. I was always under the presumption that it was getting too much water when there are yellow leaves. Please give comments being the tree is like a family member.
