Pollination of Haworthia Flowers

When you look at the not-so-attractive Haworthia blooms, the thought of pollinating them comes into your mind.

Grown for the intriguing foliage, Haworthia flowers are less charming than the pearl-patterned leaves.

The Haworthia flowers cannot self-pollinate. You need to collect the pollen from the male part and apply them to the female part.

Haworthias can pollinate naturally but are specific about the pollinators.

According to PSU.EDU, Haworthia is pollinated only by gnats and other small bugs while they are in the wild.

Gnats are more active during the daytime and dusk, resulting in more pollination.

Hand Pollination in Haworthia

Hand pollination is not that hard in Haworthia if you know the basics. Gather tweezers to collect the pollen and sterilize them.

To go on with hand pollination, you must collect the pollen from the flower on its first opening day. You can wait for the anthers to mature and get pollens on the second day.

Follow the steps below to ensure successful pollination.

  • If you see the petals curl outside, you can use the pollen as the flower is fully open.
  • Go on with the pollination in the afternoon. Remove all the petals from the male and female parts.
  • You need to remove the stamens of the female flower and keep them for later use.
  • Take 1-2 stamen from the male parent and rub the anthers on the stigma until the pollen can be seen on it.
  • Repeat this process for two days to have a greater chance of pollination.
  • After nearly a week, if you see the ovary turn green and swollen, congratulations, the pollination was successful.

For better pollination result, choose a male flower that has just opened to cross with a female parent that has opened a few days earlier.

How to Make a Haworthia Plant Bloom?

Although Haworthia is not that hard to grow, you will need to fulfill specific care requirements to make them bloom.

Look below for the optimum conditions to make Haworthia bloom.

  • Succulents need a lot of energy to be able to produce flowers. So, keep your plant in the morning sun for half a day to let it bloom.
  • Ensure your plant has enough moisture during summer and dry air during the winter.
  • Water your Haworthia only when the top 1-2 inches of soil is dry. Be on the watch for root rot.
  • Fertilize the plant with flower-inducing fertilizer rich in phosphorus during its growing months of spring and summer.
  • Maintain the temperature from 75-90°F but do not let the temperature drop below 40°F. Bring the plant inside in cold temperatures.

  • Use an organic cactus mix with good drainage and at least 30% pumice or perlite. You can also resort to bone meal for quick success.
  • A clay container that will allow too much moisture to escape is best for letting the plant bloom.
  • You can move the plant outdoors during summer and keep them in the shade of a tree or a patio.

Sometimes the flower stalks may limp down because they may not handle their weight. In such occurrences, you can stake the stem to hold them up.

What Should you do with Haworthia Flowers?

Whether to remove the white flowers or not entirely depends on your decision. Let’s look at why you should remove them.

  • The flowers are not precisely showy and add nothing to the already pleasing look of the plant.
  • Haworthia blooms take up the energy directed to the foliage; thus, the foliage can suffer consequences.
  • If you are allergic to pollen, it is better to remove the flower before the male part develops.

But keeping the flowers intact also has its benefits. First, you won’t disturb the biology of the plant by letting it bloom.

Second, you will want to keep the flowers in case you want seeds for future germination.

If you leave the flowers as they are, they will eventually wilt down and die.

  • Get pruning shears and all other gardening gears for the trimming process.
  • Hold the stalk gently and cut a few centimeters above the point from which it emerged.
  • Here is a fun thing to do: Grab hold of the stalk and pull it off the plant with your hand. Try it; it is so satisfying.
  • The pulling off is like deadheading the flower. You may not see the flower bloom again in this growing season.
  • Follow the above steps correctly and do not damage the surrounding stems and leaves.
