Why are my portulacas not flowering?

This is a very common question. In fact, I have asked this many times a few years back. Wasting months with preparation and growing efforts without getting desired results with flowering. Isn’t it frustrating- Yes, it is.

Gardening is not an overnight job, It takes time and effort. So if you are facing the same problem with portulaca. If yes, then don’t worry. First, we will discuss the actual cause of low flowering or inadequate blooming in portulaca.

  •  Lack of nutrition: It is true that portulaca is succulent and it doesn’t require much fertilization. Still, excess nitrogen or deficiency of Phosphorus can lead to reduced flowering in portulaca. All this depends on the consistency of your soil.
  • Lack of Sunlight: Sunlight is essential for flowering in Portulaca. It requires at least 6-8 hours of bright sunlight. Portulaca can be grown indoors but for propper blooming it needs heat and sunlight.

How do I get more flowers from my portulaca?

  1. Control Watering: Try to keep the soil dry ost of the time. Water only when the plants start drooping. Controlled watering is the best option to keep the portulaca plants healthy. I recommend watering only once in a week or maximum twice. Don’t worry, portulaca plant is a succulent, it will not die in a day or two.
  2. Regular fertilization: As we know, the portulaca plant doesn’t require too much fertilizer. Applying fertilizer once in 20 days will definitely increase the flowering. You can use inorganic fertilizers but I think homemade liquid fertilizer would be enough for these succulents. Try using a solution of fermented mustard cake and cow dung cake for your portulaca, moss rose plants.
  3. Proper Sunlight: Place your portulacas in a spot where at least 6 hours of direct sunlight is available. You can also place the plants in direct sunlight if you live in a frost-free zone. An increase in length without any bud formation is mostly due to the lack of sunlight. Avoid growing portulaca in dark shadow regions of the garden. Sometimes a big tree or plant can also create such a problem.
  4. Maintain Soil Consistency: Portulaca has a very shallow fibrous root system. It means the plant will get all the nutrients and moisture from the topsoil. No matter how much water or fertilizer you apply to plant, it will only take that is available near to its roots. Therefore, The consistency of soil is very important for portulaca.
  5. If the soil is hard then the water and nutrients will wash off from the surface. The soil will act as baren infertile land. On the other hand, if the soil is too porous then it will lose moisture and nutrients quickly. Though the soil is fertile now, everything is out of reach for the portulaca plants. So it is highly advised to prepare fresh soil every year for your portulaca. You cannot do this during the flowering season. The soil should be prepared in early spring or during the last frost.  Fresh soil is essential for bigger healthier bloom in portulaca or moss rose plants.

  7. Pest control: You need not worry about pest attack in portulacas except during the rainy season. During the rainy season, you can either move your plants under a shade or just apply some pesticides. Use of fungicide and pesticide is necessary only if your plants are highly infected. Else you can use rubbing alcohol to wipe out all the insects and pests. Checking for the pest attack in the portulaca plant is a tricky job. You will certainly not find any bugs during day time. You should do this in the early morning or in the evening. We can also check for any bugs in dead flowers.
  8. Removal of dead flowers: Seed formation is a reason for reduced flowering in portulacas. So if you think this is the problem then act quickly. Try to remove all the dead flowers and branches from the plant. I know to deadhead in portulaca is not very easy but if you manage this somehow then the result will be beautiful. Deadheading in portulaca is a time-taking difficult job but it is also the best option to increase flowering.
