Duranta plant fertilizer
To get my 2nd yr Duranta to bloom, what formula of fertilizer should I use? I have read that it needs to be "slow." Which mixture 10/10/20 or what?
You'll want to get your soil tested to determine which slow-release mix is best for your Duranta (unless you already know your nitrogen content). Many local university extension offices can help with this (more about extension offices here: https://www.gardeningknowhow.com/garden-how-to/info/what-is-extension-service.htm)
Once you know the nitrogen content of your soil, this site will walk you through determining the appropriate mixture:
And this article provides some tips on caring for Duranta plants:
Duranta are heavy feeders. Fertilize with 1/2 tsp of fertilizer by gallon of water once a week. Use a balanced formula like 15-15-15 or a blossom booster formula 7-9-5. Do not fertilize in winter.
If the leaves are yellow and drop from the plant you can increase fertilizer to twice a week until the plant greens up.
