4/12/2021 – The heavy rains at the end of last week surely washed out some of the fertilizer—especially the nitrogen and potassium—we have placed in the past month or two. The roses, daylilies, grass, i.e. everything else is/was setting buds and on the way to being the best yard we ever achieved. To preserve that momentum, we decided we need to re-fertilize everything.
4/13/2021 – The concoction was fed to the Roses, Daylilies and all other lilies.
Researching for what to do after a major rain lead to the following sites.
- Tips for your yard and garden after heavy rains or flooding
- Nitrogen losses after the heavy rains
- Nitrogen loss: How does it happen?
- Nutrient Leaching paper by Cornell University – Extensive paper that addresses magnesium and calcium leaching.
The interesting info in the first link was that nitrogen and potassium leach out whereas phosphorus does not. The last link to Cornell addresses magnesium and therefore we included Epsom Salts in the “concoction“. With that in mind, we devised the following plan.
The 3.33 lbs of 15-0-15 per 1,000 SF as a low maintenance feeding of lawn grass came from this post.

The day after I was reviewing this page and noted the 4th link above to Cornell about magnesium leaching. I was wrong when concerned that the magnesium would build up in the daylilies if we added Epsom Salts to the concoction. That mistake lead to some of the entries above showing that Epsom Salts was not included. The daylilies in the backyard bed along the azaleas did get the brew with Epsom Salts.
