Potting Mix for Rajnigandha Plant Care

Rajnigandha plant requires fast draining and nutritious soil to grow healthy and bloom its fragrant flowers.

Fast draining soil is necessary because if the water stays for too long inside the soil, the roots of the rajnigandha plant will start to rot as they are very susceptible to it.

So, make sure to use a potting mix that is rich in compost as well as full of nutrition.

You can make your own potting soil by mixing the following ingredients:

Rajnigandha Plant Not Flowering – Why Is My Rajnigandha Not Flowering

Rajnigandha plant, not flowering is caused due to 3 reasons:

  • Lack of Sunlight
  • Root Bound Condition
  • Not provided Fertilizer

Lack of Sunlight

If your rajnigandha plant is not getting enough sunlight, this can be the reason behind it not flowering.

So, once the summer season has passed, you should expose it to direct sunlight, and if the summers in your area are not very harsh, you can keep it under direct sunlight. Only move it under shade if its leaves start to turn brownish.

I can understand that many people live in an Apartment/Flat and don’t receive direct sunlight in that case you can get these Grow Light which will help provide it with the right amount of light it needs.

Root Bound

Your plant might be root bound, which means that it has outgrown its present container. I recently faced this condition when one of my rajnigandha plants had stopped growing and producing flowers.

If this is the case, then you will see that its root has started to come out of the drainage holes, the container gets very stiff than what it used to be and the plant stops growing.

So, you will need to move it into a one-size bigger container and you will see it will start getting normal within a week.

Not Providing it enough food:

Rajnigandha plant needs a good amount of nutrition to bloom and if you fail to do so, then it will not flower.

Make sure to feed it with quality fertilizer during its flowering season, I highly recommend this fertilizer for the rajnigandha plant.

Also, make sure to water it after feeding it with fertilizer.

Sunlight Requirement of Rajnigandha Plant

Rajnigandha plant is a sun-loving plant that requires full sunlight by that I mean:
6-8 hours of sunlight to thrive well.

I used to keep my rajnigandha plant under direct sunlight even in the summer season and it was going well,


As the temperature started to rise even more.

I saw that its leaves started to turn brownish and very dry.

And was advised to keep them under shade as the sunlight was too much for them as they were getting sunburnt.

If sunlight in your area is very harsh as was in my case.

Rajnigandha flower under green net

I would advise you to get a good quality green net and put it under it.

In this way, it will get filtered light, which is neither too light nor too harsh for your plant.

Also, during the rainy season, it will save your plants from getting overwatered from rain which is also very crucial.

How to Water Rajnigandha Plant for Proper Care

For proper rajnigandha plant care, watering is what matters the most.

Because if you mess up with watering the rajnigandha plant, then things can go the wrong way.

Rajnigandha plants love to stay under sunlight, so the soil dries out quite quickly.

So, for good watering practice, what you must do is:

Before watering it, make sure that a few inches (1-2) of the soil have dried out, if they feel dry, give it a good bath.

But if it feels wet, then skip watering.

During summers you will need to water it more frequently than in winters.

If the soil seems very wet and soggy all the time, it means that you are overwatering your plant and should stop watering it the same way, otherwise, your plant will have root rot very soon.

Or, if you see that the soil has all dried up and has cracks in it, you are underwatering your plant, this will also harm your plant.

The rule is to keep the soil moist all the time.

Mulch is simply a layer of different material (often organic) applied on top of the potting soil.

Covering the top layer of the potting mix with mulch helps retain the moisture as liked by the Rajnigandha plant.

You can use dried leaves or small wooden sticks for mulching your plant.

Mulching also prevents the top of the soil to dry out very quickly and is very favorable in the case of rajnigandha.

9 o’clock flower plant – How to Grow


You should always choose a good size container (grow bag or Pot) for rajnigandha.

As its bulbs are sown quite deep inside the soil and its roots also grow deeper.

So, the ideal size of container for rajnigandha will be 10 – 12 inch pots or grow bags.

For drainage always make holes at the bottom of the container, as it allows waters to go out of the container and avoid rotting of roots.

This is a must thing for almost every plant you grow in a container.


As Rajnigandha plant is a heavy feeder.

Provide it with compost every 6-7 weeks.

Keeping the soil full of nutrients is very much needed during its flowering season, which is from:

Late June – Sept and my rajnigandha plant bloomed even during Feb – March.

For this, you can give it a (19:19:19) NPK fertilizer or rotted cow dung.

But make sure you don’t provide fertilizer in the afternoon as it can burn the plant leaves and apply the fertilizer right in the soil and not over the leaves of the plant.

And every time you apply fertilizer, water a bit for it to release nutrients.

Discard The Flowering Stalk

Removing its flower stalks as soon as the flowering stops are also very necessary so that it doesn’t take up nutrition from the soil and allows space for more flowering.

Just use a knife or scissor and cut 75% of the flower stalk and let the 25% get dried completely then you can easily pull it off.
