Despite its invasiveness, the plant with its beautiful flowers would still be an excellent addition to your garden as a bordering bush.

You only need to make sure about the garden layout so that the plant does not attack other nearby plants.

  • Sunlight

  • Soil

It needs fertile soil, loose, and well-drained. To maximize growth, you may mix the soil with organic compost.

It is important to keep the soil well-drained because the root tends to rot when it retains too much water.

Make sure that the root ball is not buried too deep. Cover the top root ball side with soil until it forms some kind of a mountain down the stem.

  • Watering

Some pests that may attack this Buddleia are caterpillars, capsid bugs, spider mites, and weevils.

The easiest one to handle is the spider mite. Get a spray of cold water between 0 – 4 Celsius degrees to get rid of it.
