Pink oleander not flowering

Question

I bought 2 pink oleander shrubs about 2 years ago and they have never flowered. I have given them fertilizer and kept them watered in the dry weather. What am I doing wrong?

Answer 1

Fertilizer is generally only recommended the first year they are planted to help them become established.
They likely have too much nitrogen to bloom. Excess nitrogen will cause lots of green leaves and no flowers.
You can give the plants some phosphorous to promote flowering.

If you still have no flowering, you will want to do a soil test to correct the soil.
