How to Propagate Oscularia deltoides Succulents? A Detailed Guide to Its Flowering Habits
Oscularia deltoides is a rather interesting succulent with a very unique trait: it usually chooses to bloom between 2 and 3 p.m., which is the hottest and brightest time of day in the Northern Hemisphere, so people call it Oscularia deltoides.
How to Propagate Oscularia deltoides
Yellow-flowered Oscularia deltoides is mainly propagated by division. Cut a piece from the old plant and insert it into soil, and it will take root after a period of time. Propagation is better in spring and autumn; the success rate in the other two seasons is not high.
When dividing, first take the parent plant out of the pot, shake off the outer soil, and use a sharp knife or pruning shears to cut apart the underground stems connecting the leaf clusters, so they can be divided into several plants and planted separately. The timing of division propagation varies with the type of flower; yellow-flowered Oscularia deltoides, which blooms in autumn, should be divided in spring.
The specific method for division propagation of yellow-flowered Oscularia deltoides is: first remove the soil from the parent plant, then, following the natural spreading intervals of the roots, separate them by hand or cut them apart with a sharp knife along the gaps. Each plant should be divided into only 2-3 plants, not too many, and the number of roots and branches separated should match appropriately so that the whole plant remains balanced and even. After separation, trim them and remove rotten roots. If conditions allow, coat the cuts with charcoal powder or sulfur powder for disinfection before planting.
Does Oscularia deltoides Bloom
Oscularia deltoides does bloom, generally producing yellow flowers in spring. Because Oscularia deltoides usually blooms at 2 p.m. in China and at 3 p.m. in Japan, it is also called the three o'clock flower.
How to Grow Oscularia deltoides into a Full Pot
1. Achieve a full pot through division
Under normal circumstances, yellow-flowered Oscularia deltoides can be propagated by division and cuttings. From a mature succulent, cut off a section starting two to three nodes down from the top. At this time, note that the scissors must be disinfected with alcohol before use to avoid infection. Then pull off the lower leaves of the earliest plant to prevent excessive evaporation of nutrients and water.
2. Achieve a full pot through leaf cuttings
The cut branches can be used for stem cuttings, and the leaves can also be used for leaf cuttings, so if one propagation method fails, there is still a backup plan. Then plant the cut branches and leaves into clean soil. Be sure not to overwater or expose them to too much direct sunlight, and then slowly wait for them to root and sprout! In this way, we complete the first step: filling the pot with yellow-flowered Oscularia deltoides.
3. Best season for a full pot
Generally, the two seasons are spring and autumn. One reason is that summer temperatures are too high, often above 35°C, and at this temperature it stops growing. Winter, however, is too cold; when the temperature is below 5°C, it also stops growing, and some branches may even suffer slight frost damage. In some places the temperature drops below zero, and at this time its leaves may freeze to death, so it is not suitable for large-scale division propagation.
Although the success rate of propagation in autumn is very high, because this succulent blooms in autumn, the more suitable season is spring. After successful propagation, it can grow very vigorously in one summer, and by the time it blooms in autumn, it will have filled the pot.
Care Methods for Oscularia deltoides
1. Water
After the seeds sprout into new shoots, watering should follow actual climate needs. In spring and autumn, water once every half month, preferably on a sunny day with good light, and even more precisely at noon; the leaves can also be misted. As with growing other flowers, winter temperatures are lower, so to avoid frost damage, reduce the frequency of watering and increase the role of light, keeping the soil in the pot dry.
2. Fertilizer
Summer temperatures rise, and the conditions in this season are exactly favorable factors for the growth of Oscularia deltoides, so it grows quickly. Growth requires a lot of nutrients, so fertility must not be reduced. A thin fertilizer can be applied once every two weeks, preferably a specialized fertilizer.
3. Sunlight
Oscularia deltoides likes sunlight, but it cannot be exposed to prolonged harsh sun, which would cause severe evaporation. Summer has long hours of sunlight, so outdoor-grown plants should be shaded, or moved indoors to a bright, ventilated spot near a window.
4. Temperature
Once Oscularia deltoides is stable and established, it is relatively easy to care for. As long as you prevent prolonged drought or waterlogging and keep water and temperature under control, it can survive even at low winter temperatures. As long as the temperature is kept above zero, it can grow vigorously and even produce yellow flowers.
Oscularia deltoides is also called yellow-flowered Oscularia deltoides, which simply means that Oscularia deltoides produces a very distinctive yellow flower, so Oscularia deltoides will certainly bloom. From the name Oscularia deltoides, we can see that Oscularia deltoides is a succulent that very much likes sunlight.
