What’s the best fertilizer to promote growth of plants like sweet olive and crepe myrtle? I have lorapedlums, too, but they actually grow faster than I’d like. Also, would the fertilizer be different for flowers like hydrangea?

interested. I just put out some Milorganite in my backyard and the Lowe's brand of organic fertilizer in the front. I sprinkled some of that in my flower beds also.

I use a “slow release” general purpose balanced 14-14-14 fertilizer on shrubs (Lesco brand purchased from Site One). If you read university extension publications most will recommend a fertilizer something like this. One application in spring usually is sufficient, maybe a second application in May/June if you are trying to push growth.

A portion of the nitrogen component (urea) is coated with elemental sulfur which provides the slow release of the nitrogen over several months.

If you are referring to traditional mophead type hydrangeas, acidic soils promote blue color, alkaline soils, pink color.

A fertilizer in which the nitrogen form is either ammonium sulfate or urea (as opposed to nitrate) will promote slightly acidic conditions. The elemental sulfur coating on urea to extend the release of nitrogen will also promote acidic conditions. The chemical composition of the fertilizer, whether it be nitrogen, phosphorus or potassium will always be on the fertilizer bag or container.

P.S. I use the same fertilizer on young trees.

I put 10 10 10 out with a hand spreader. Works good for me.

Synthetics are not good for loropetalum. See if you have a local supplier of Microlife. Great organic, that you can use on everything.

That Fertilome tree and shrub fertilizer is a good product and readily available at hardware stores and retail plant nurseries.
