The best fertilizer for Japanese maples, conifers, ornamentals, and perennials wrote

I have very rare specimens and want to keep them healthy, with a full canopy, and growth that is true to form. This fertilizer is great for keeping your plants and soil healthy. Their is just no comparison between this fertilizer and any other organic or chemical slow release fertilizer. This is the only fertilizer that I can recommend with confidence. I use it in April, the end of June, and then use their PHC azalea fertilizer as a winterizer at the end of September. I use half the recommended dose for all landscape grown and container grown plants.

Happy with your service. wrote

I haven't planted yet, but this had the numbers 7-7-7 I wanted. I also like the fact it has microbes. If it works like I think it will, I plant to buy it here in the future. I'm very happy with your service and highly recommend you.
