Balanced slow-release soluble 10-10-10, blood meal, compost, fish emulsion, and mulch are fertilizers to use on oleander (Nerium oleander). Compost can be applied as as soil amendment, fertilizer, or mulch. Applications may be made in late February or early March and in late September or early October, when temperatures will not be so hot as to "burn" the soil with added nutrients.
