Reasons Why Your Cactus is Not Blooming:

Underwatering:

The underwatering issue is one of the most common causes that can make your cactus plant suffer unavoidably. Most gardeners think that as it is desert-born, cactus plants don’t need moisture at all.

But in reality, indoor cactus plants require as much moisture to thrive as a common succulent wants. Thus, they may suffer from the consequence of underwatering like stunt-blooming. This kind of situation occurs when-

  • When you don’t water your plant for weeks
  • If your plant is going through drought stress
  • And when the roots also start drying along with soil due to being underwater

Over Sun Exposure:

Unlike other flowers, flowering cactus plants actually need darkness more than open sunlight to bloom. Thus, they can’t get bloom buds when you get your cactus plant into the full sun exposure for long.

You should be aware of the actual need for the light of your chosen cactus variety to make it bloom naturally. Some common faults you make during the way of providing light to your cactus, are-

  • If you place your cactus plant under direct sunlight for several weeks
  • When you can’t provide your plant with adequate darkness during its budding period
  • If you let your plant burn under dappled sun heat for long

Pot Bound:

Cactus plants don’t need a heavy or complicated root system, yet you should provide a large or wide pot to grow a cactus plant indoors.

To keep the root of your growing and flowering cactus species, you need to choose a planter that is almost 3-4 sizes larger than its root ball. But, sometimes, we make some common mistakes while cultivating the cactus plant, like-

  • When you pick too small a pot to sow a cactus plant
  • If we upgrade the planter of a growing cactus after repotting
  • When your cactus plant isn’t getting root bound ever throughout its entire growing session

Improper Climate:

Despite being of a desert origin, cactus plants can’t tolerate much fluctuation in their growing temperature. They can’t even thrive under unsuitable humidity levels as well.

Your indoor cactus plant may keep growing and living under a bit of mismanagement sometimes. But they never bloom flower buds in any kind of climate that is not blooming supported. Mistakes that can prevent your cactus plant from blooming are as follows-

  • If you place your plant in a cool damp place for several days
  • When you don’t maintain the optimal growing temperature for your plant
  • If you keep your plant in a low-humid place for long

Soggy Soil:

Like underwatering, overwatering can also be a cause of not blooming. Even though a growing cactus plant needs enough water, it needs an airy growing medium to thrive.

If you overwater your plant unnecessarily, it will make the entire growing medium unsuitable for the roots of your cactus.

Being a hardy plant, may your cactus survive the phrase but it will surely stop blooming immediately. Some causes of happening this issue to your plant-

  • When you water your plant more than twice a week
  • If you use saturated soil or potting mix to grow your plant
  • Soil is soggy or water-logged due to poor drainage

Overfertilization:

Cactus plants are native to the rainforest and desert areas. Thus, they don’t need much fertilization to thrive or produce flowers.

If you feed your plant with high-nutrient plant foods unnecessarily, it will cause stunt growth or not-blooming problem in your plant soon.

So, you need to feed your plant adequately instead of superfluously. This sort of overfertilization issue occurs in such cases-

  • When you feed your plant during the bud formation session of the year
  • If you apply readymade commercial fertilizer with full strength
  • When you feed your cacti in late summer needlessly
