How to Fertilize Oleanders?

Oleander Growing on Ground

Mature oleanders rarely need feeding as they absorb nutrients from the soil. You can also amend it by adding compost, cow dung manure, or peat moss before planting.

If the plant shows the sign of nutrient deficiency like yellow or pale green leaves, small-sized leaves, or fewer flower production, use a 10-10-10, granular fertilizer. For dosage, check the label. Feed the plant once in February to March and then once from October to November.

Note: Never feed the plant during hotter months of summer, as it will burn its roots.

Oleander Growing in a Container

Potted oleander plants need feeding periodically. Use 10-10-10 granular fertilizer once in 4-6 weeks.

Bonus Tip: You can encourage abundant flowering by feeding oleanders with tomato or vegetable fertilizer or any fertilizer high in potassium.

  1. Make sure that the plant is getting plenty of sunlight. Oleanders can tolerate partial shade too.
  2. Deadhead flowers once they die out. This encourages new blooming.
  3. Prune the tip of stems after the flowering period to stimulate new growth. Also, snip off any crisscrossed, broken, or diseased branches from time to time.
  4. Remove pests and mites from the tree. You can also use a neem oil solution to prevent any fungal or pests infections.
  5. Grow it in well-draining soil, porous, and fertile soil.
  6. Mulch the soil of the shrub with grass clippings, or barks to maintain an even temperature.
