The oleander, with its vibrant colors, perfectly embodies the atmosphere of a Mediterranean garden. However, it’s not uncommon to notice some difficulty in revitalizing it by spring: yellowed leaves, bare branches, or simply the absence of flowers.

Your oleander may be going through a tough time, but rest assured, with some good practices, you can quickly restore its natural vigor. Here’s how to revive your oleander now to enjoy a beautiful floral display all summer long!

Take the time to observe carefully the status of the oleander

Do you know the precise state of your shrub? Before taking any other action, carefully examine your plant to target the necessary care.

Here are the essential points to check:

  • The appearance of the foliage: is it dry, yellowed, or damaged?
  • The flexibility of the branches: are they still supple or brittle?
  • The possible presence of pests such as scale insects or aphids, recognizable by their sticky honeydew.
  • Any signs of diseases such as fungi or trunk rot.

If the branches still have some flexibility, you can have hope: your shrub may very well regain its beauty!

Prune the branches effectively to help your plant restart

What if the solution began simply with appropriate pruning? A good refresh can greatly benefit an oleander struggling to push through.

It may seem paradoxical, but it is perfectly suited to this vigorous Mediterranean shrub.

Tips for pruning:

  • Always use a sterilized and sharp pruning shears to avoid any contamination.
  • Completely remove dead or dried branches.
  • Eliminate weak or poorly oriented young shoots to restore energy and balance to the plant.
  • Gently prune the tips of the healthy branches to encourage new growth.

Be careful not to overdo it: excessive pruning could weaken your oleander even more.

Adopt appropriate watering to promote growth restart

The oleander is resistant to dry spells but still appreciates regular watering, especially as summer approaches, a time suitable for the development of beautiful flowers.

How to water effectively?

  • Water deeply and generously once a week, ideally in the morning to limit evaporation.
  • Add a mulch layer of bark at the base to retain more moisture.
  • If potted, always check that water does not stagnate to avoid root rot.

Give it a nutritional boost with the right fertilizer

If your oleander still looks a bit tired, offer it a nutrient cocktail specifically designed for flowering Mediterranean plants to effectively kickstart its growth.

What type of fertilizer to choose?

  • Choose a fertilizer for flowering plants, rich in phosphorus for a strong root system, and potassium for abundant flowers.
  • Avoid formulas too rich in nitrogen: they promote foliage at the expense of flowers.
  • For optimal results, apply these nutrients every two weeks, from May to autumn.

Give it an optimal dose of sunshine

Is your oleander getting enough sunlight? This Mediterranean shrub particularly enjoys heat and requires a minimum of 6 hours of daily sunlight to thrive fully.

If your plant is too shaded, here’s how to intervene:

  • Gradually move your potted plant to a brighter spot.
  • For a shrub in the ground, clear as much space as possible by cutting any nearby branches that cast shade on it.
  • Absolutely avoid places exposed to cold drafts that may be fatal to early spring shoots.

Quickly identify pests to act urgently

Your oleander might suffer from some unwanted visitors:

  • Scale insects: easily identifiable by the sticky honeydew, use a soapy water spray to eliminate them.
  • Aphids: a simple water jet usually does the trick. Otherwise, diluted black soap is also a healthy and effective solution.
  • Sooty mold: this black deposit often comes from the presence of scale insects. Wipe it gently with a damp cloth to restore its health.

Regular inspections will help limit damage and maintain your plant’s vitality.

Protect your shrub from last cold spells

Even in May, late frosts can cause damage to your precious oleander. So, stay vigilant:

  • Protect your potted plants with a winter cover or place them in a sheltered area, close to a south-facing wall.
  • Install a thick layer of mulch at the base of your shrub in the ground to protect its roots from the cold.

Signs of recovery to monitor for peace of mind

After implementing these tips, you should quickly see green and vigorous shoots appearing. This is a sign that your oleander is coming back to life!

From there, simply maintain a regular watering schedule, provide nutritional support, and keep it comfortably exposed to sunlight.
