Fertilizer question - for oleanders specifically and observation about storage
Posted by Brad - Pittsburgh on 4/7/2017, 6:43 pm
I have a oleander which I dig and store yearly. In past winter I had stored in the basement where it did poorly, had heavy scale infestations, and once even completely defoliated. This year, I stored it in the garage, took it out when it was nice, and it responded by looking better than ever after winter storage.
Here's the loaded question. 2 years ago, it bloomed spectacularly all summer long, and last year it barely flowered. Each year it was in the same spot and I fertilized the same way. At planting time, I took roughly 3 parts Espoma Plant-tone 5-3-3, 3 parts Flower-tone 3-5-7, and 1 part Rock Phosphate 0-3-0. I know, real scientific. I read recently that oleanders do not require fertilization. I am also planning on moving it this year to the center of my desert bed with 50/50 sand gravel, plus some soil from the previously planted plant in the bed that didn't make it through winter (RIP washy and Med fan). I figure the oleander can take the dryness and may even help it, but should I or should I not fertilize it, and if so, how?
