I have two trumpet bushes that don't grow much leaves. I see other trees bushes that have wonderful folage, lots of lush leaves. But mine has very little leaves but flowers continually, lots of flowers. I live in southern california. What am I doing wrong. Does it need to be cut back in a spedcial way or need special mulch or food. It has many spider plants that are planted all around it that are doing just fine. The soil here consists of lots of clay. One bush has many seperate stems? Some of them have very little leaves but blooms just the same.. Please help any advise would be helpful..
..lack of Nitrogen.
Go to the store and get some fertilizer. If you don't know already, there are 3 number sets listed on the packages, they may be say 10-20-10 etc.
The first set is the nitrogen content. Get some with the number 15 or above.
If you have a lawn, fresh cut grass is a good source of nitrogen. you can either lay it on top like a mulch or work it into the soil. I do this all the time with my Corn since Corn is a big nitrogen feeder.
