How to fertilize allamanda plants?

Here are the steps to fertilize these plants:

  1. Start by removing any dead branches or dying leaves from your allamanda plants. To do this, take a pair of sanitized scissors or pruning shears and prune the plant from the top down. This way, the nutrients from the fertilizer will go to the healthiest leaves, as opposed to being wasted on dying foliage.
  2. Pre-water the soil by giving it about half of the normal amount of water that you'd typically give it in a typical watering session — you never want to apply fertilizer to dry or crumbly soil. Make sure that the soil is slightly moist before applying the fertilizer, and it doesn't matter if your fertilizer is granular or liquid.
  3. Measure your fertilizer according to the instructions and dilute it as needed. If you're using granules, use the recommended amount and be sure to space them around the soil evenly.
  4. Apply the liquid fertilizer on top of the plant's soil, covering the entire surface and not just one area.

How do you make allamanda bloom?


For allamanda plants to bloom, they'll need sunlight, fertilizer, and pots that allow them to be root bound. If your allamanda is planted outside, you'll need to keep a careful eye on the temperature. These plants don't tolerate cold conditions well. An average temperature over 70 degrees Fahrenheit is ideal, and anything under 65 degrees Fahrenheit can cause the plant to fail to bloom.

How fast does Allamanda grow?

They grow pretty fast, actually. A typical allamanda can grow anywhere from 10 to 20 feet in a single season if it receives enough nutrients and sunlight. It's best to keep an eye on these plants if they're planted indoors as they can quickly, as their vines can quickly spread across a room.

How tall do Allamanda plants get?

If left to grow without pruning, they can reach up to 15 to 20 feet tall. However, you'll find that most gardeners keep these plants at about 4 to 5 feet in height. Their average span can be anywhere from 2 to 3 feet wide.

Can you grow Allamanda in pots?

Absolutely. These plants love to be root bound, and they can be grown very effectively in indoor environments. If you're growing them indoors, just be sure that the plants receive at least 4 to 6 hours of sunlight a day to encourage growth. Let's take a look at a couple of pots to consider.
