Excel 15-5-15 Cal-Mag Special w/Black Iron (1) 1 1lb. Bag.

Magic sauce for seedlings! So safe it can be used on any plants and seems to benefit everything I've used it on (salvias, pansy, villas, marigolds, snapdragons, begonia, geranium, etc al)! I am loyal to this brand! They have excellent product support also. You can ask their experts any question and they will answer. Love this stuff!

I have been watering my plants with reverse osmosis water and a different fertilizer for many years. Before using this, I had started having issues with a few cattleyas producing new growth that promptly turned black. I believed it to be a nutrient deficiency, and was right. After using this fertilizer, they are now producing new, healthy growth! I will continue to purchase this product!

Using this on my orchids and I found that the ph levels dropped dramatically. I started out with 7 ph using ro water added the fertilizer at 1/4 tsp for a gallon and the level dropped to 4.5. Don't want to correct using other chemicals like ph up, too much of a hassle. I can't say how this will work with your tap water but please check your ph.

My orchids look wonderful with lots of blooms. I use both the Peter’s fertilizers

Es un nuevo producto para mis antas pero con las references q e mirado esperamos buenos resultados.

Orchid growers always recommend 15-5-15 fertilizer 3 - 4 times/year from March thru Sept.Following the instructions will produce healthy growth.

Supposed to be a granular fertilizer to be mixed with water at time of use. Package came with moisture inside and will not dry. Continues to get wetter even after transferring from plastic package to a container from a 20-20-20 fertilizer of the same type. Not sure if getting the full effect or if it will damage my orchids.

My orchids have never been happier or looked so good. I can afford to give them the best because sellers like this make smaller quantities of premium products affordable to just an average hobbyist! This repeat customer could not be happier with the product and customer service I received.
