9 O clock flowers are self seeding which can produce beautiful blooms all summer long even with little or minimal care and low maintenance. Here, we will be discussing some ideal conditions to grow this plant more gracefully.


It thrives in direct as well as indirect bright sunlight. It needs medium direct sunlight for about 3-4 hours in order to bloom properly. The blooms become more vibrant in exposure to ample light.


Temperature ranging from 20 to 30 degrees celsius is ideal for this plant. Being a high heat tolerant plant, it can even easily tolerate afternoon heat and is sensitive to cold. It should be taken indoors during winter.


9 O clock flower grows best in well aerated sandy and sandy loam soil. The soil should be loose and quick draining in order to flush out lodged water in no time. This plant can even grow in the small amount of wind deposited soil in old cracks and stone walkways.


This plant doesn’t need frequent watering as it is drought tolerant succulent. Water it only when about 2cm deep soil feels dry by inserting the fingers into the soil. Overwatering can lead to root rot. While watering, one should keep in mind not to water the plant and its flower directly from above, but at its base.


This plant is sensitive to cold as it is native to high heat climates. The plant should be transferred indoors on increasing humidity.


Fertilising the plant frequently may lead to increase in foliage size but reduction in flower numbers. FYM or vermicompost can be mixed into the soil to increase drainage and nutrients during its blooming period once a month. However, the plant can grow well even without any fertilisers.

9 O Clock Flower Propagation

The 9 O’clock flower plant can be easily propagated mainy by two methods:

1. By seeds

2. By cuttings

The detailed procedures to propagate it through these methods is described below:

By seeds

Growing a new 9 O’clock plant from seeds is quite an easy process. As they are self seeding plants, the seeds are easily available.

  • First, a quick draining soil with good water retention quality is prepared by mixing Loamy soil, coco peat, FYM or vermicompost and some Neem khali as anti-fungal.
  • Take a wide pot or any container and make some holes to favour drainage and ventilation.
  • Fill up the pot tightly and make it moist by watering.
  • Spread the extracted seeds uniformly over that soil.
  • A thin layer of soil is added above it making sure not to interfere with the light rays required during germination.
  • Water it again lightly and keep the pot in shade.
  • Water it only when the soi becomes dry by measuring it with your fingers.
  • Once it germinates in about 1-2 weeks, move the plant to the sunlight area as it starts growing quickly.
  • Place the plant in an area with direct sunlight and enjoy its beautiful blooms.

By cuttings

The propagation by its cutting is quicker than by seeds. We have to follow some simple procedures listed below:

  • First, prepare a well-draining potting mix and select the container.
  • Fill up the container and make it moist.
  • Take a 2-3 cm cutting of a 9 O’clock plant with leaves.
  • Prepare a hole of about half inch at the centre and bury the prepared cutting in it.
  • Water it lightly and keep the container in shade.
  • After 3-4 days a significant change can be seen in the plant due to development of its roots.
  • Relocate the plant to direct sunlight and let it bloom beautifully.

Common Problems


Aphids: It infests the plant by sucking out the juice from its leaves. Whole plant may get infected on prolonged infection.
