Have to admit. Dan Trimmer offered me a small part bag of 360-day fertilizer that he uses on his daylilies. To be nice I asked that he get me a full bag next time he orders them. I do reimburse, and get it at his cost. Early spring 2019 (February) I put a mix of fertilizers on my daylilies as usual. This time I used the 360-day instead of the 9 mo fertilizer I've used before.
In Florida usually daylilies look spent in October. They have been fertilized but heavy rains wash it out (thus feeding queen palms and any other plant near the boxes). Even our intense sun causes fertilizer to release too fast. Just this month, we've had about 7" of rain. Imagine my surprise as my daylilies exploded this month, keeping their bright green foliage, adding new fans and just generally looking like they do in April. Huge, beautiful, happy daylilies!! That 360-day fertilizer is a keeper! It lasts despite our weather and keeps the daylilies looking in their prime even in Florida. I emailed Dan and he just said "just smile and enjoy". That's exactly what I'm doing.
Now a have a full bag + 3/4 of a bag of that stuff. In the garage where it stays day.
