Fertilizers for ornamentals contain less than 2% chloride...due to the potassium source material. K sulfate over K chloride. The K sulfate is more expensive so be sure to check the label.
Most fertilizers say right on the bag what it's for too.
Turf can withstand higher levels of chloride....ornamentals (shrubs, trees, groundcovers, etc) cannot.
Then.....high quality fertilizers contains slow-release nitrogen...and sometimes potassium. Both of which can readily leach through the soil.
The label will reveal the amount of slow release and from what source material. Niroform is the blue stuff...there's also sulfur-coated and encapsulated (Osmocote and Nutracoat). And others.
If you have a
Site One nearby - you can go there and get what you need along with professional advice.
Home Depot carries "Lesco" brand (in limited types) - which is what
Site One also sells.
Also, most trees/palms that are planted in the yard that has turf which is fertilized, get plenty of their nutrients from the turf fertilizer, so do not need anything else.
One more tip.....most nurseries and tree farms maintain a supply of fertilizer for their own use. They have it brought in by the pallet. You may be able to buy a bag or two directly from them - and thus get something of high quality not as easily obtained as a consumer. I used to do this as a contractor - offering a quick "cash sale". Sometimes that is a helpful inducement.....sometimes not. Depends on if you're talking to the actual owner or not, etc.....many factors.
I would try Site One and/or Home Depot, otherwise.....
