Lantana Plants

Q.Would like to know if there is a reason my lantana is not flowering?

Zone 9b Southern California | Rockafelladw added on April 9, 2019 | Answered

I planted 2,000 1 gallon lantana plants last spring on my slope. They bloomed well. I live in Southern California zone 9b. The winter turned many of the leaves brown and purple. The lantana with purple and white flowers are blooming again. The lantana with red, orange, and yellow are not blooming. I have not pruned them. There are stores down the street from me with lantana in their landscaping in full bloom. Why are they not flowering again for me, being that it’s April?

Hm... I would look to having your soil tested. This could be a nutrient deficiency of potassium or phosphorus. Either that or a pH imbalance that will appear as a deficiency.

I would recommend sending soil samples to your nearest extension service. They will be able to give you a full soil analysis. This link will help you to find the closes one to you: https://www.gardeningknowhow.com/extension-search
