Detailed Explanation of Key Techniques for Summer Care of Clivia

Just like its name, Clivia is like a modest gentleman, and it is especially endearing as it grows. Whether in bloom or not, it is an excellent ornamental plant, and many people like to keep a pot of it. Its leaves are emerald green, and its flowers bloom in clusters, making it very appealing. However, when growing Clivia, you may also run into many disappointments, for example, yellowing Clivia leaves, which is quite common...

Clivia has a dignified plant shape, neatly arranged leaves, and glossy, oily-green foliage. It is often said that its flowers are surpassed by its leaves, and it is a type of flower that people very much like to grow. So do you know how to select Clivia? Below, follow the editor to take a look at Clivia selection tips. In judging whether a Clivia variety is good or bad, its leaves account for a large proportion. So what characteristics do the leaves of top-grade Clivia have? 1. The leaves of top-grade Clivia should be short and wide, with a length between 9 cm and 12 cm, and a length-to-width ratio within 4:1. Some varieties can reach 2:1, or even 1:1, such as Henglan.

Clivia, as soon as you hear the name, makes people think of the character of a gentleman: upright, noble, and elegant, so many people want to grow a pot of this plant. The suitable growth temperature for Clivia is 20-25°C. When the temperature exceeds 30°C, it enters a semi-dormant state. This is a difficult period for growing Clivia. If care is improper, it can easily lead to yellowed, withered leaves and rotting stems and roots. In order for Clivia to get through summer, summer care measures for Clivia must be done well. The specific methods are as follows:

Cooling Down Clivia in Summer

Shade and cooling: In midsummer, provide shade, and spray water 3-4 times a day, and water thoroughly once every 2-3 days. Sand cooling: Place a tray under the flowerpot and fill it with sandy soil. Sprinkle water on the sand surface 3-4 times a day. When the moisture contained in the sand evaporates, it absorbs heat from the air, thus achieving the purpose of cooling. Water tank cooling: Place a piece of hard miscellaneous wood board or a cement precast slab on top of a water tank filled with cold water, then place the flowerpot on the wooden board or cement slab. As the water is heated and continuously evaporates, it can both increase air humidity and lower air temperature.

Controlling Light for Clivia

In midsummer, it is ideal to let Clivia receive 2 hours of morning light each day, and shading it at other times is also fine. If conditions do not allow morning light, a half-shading method is also acceptable, that is, placing the flowerpot under tree shade or a grape trellis. If placed indoors, it must be kept some distance from a south-facing window, and a white curtain with openings should be used to block light, so that Clivia receives "dappled light." Otherwise, direct sunlight can easily cause sunscald. In addition, no matter which method is used to control light, the sunny side should be adjusted about once every 10 days to ensure that the leaves grow neatly.

Proper Watering for Clivia

Although the amount of watering in summer is greater than in other seasons, you should still adhere to the principle of not watering until the soil is dry, and watering thoroughly once you do. Do not water as soon as the surface soil looks dry, otherwise the potting soil will remain in a muddy state for a long time, easily rotting the fleshy roots and causing yellow leaves. Especially under poorly ventilated conditions, water less.

Root Rot in Clivia and Solutions

Clivia sometimes develops root rot. This is mainly caused by high temperatures, excessive watering, application of concentrated fertilizer, or pathogen-bearing uncured potting soil. Root rot generally has two situations: one is that most of the root system is still good and only part of the roots have rotted; the other is that most or all of the root system has rotted. For the first situation, the rescue method is: after discovering root rot, immediately knock it out of the pot, carefully remove the attached soil, rinse the root system clean with clean water, then use a clean, sharp blade to cut off the rotted roots, and then apply a 0.1 potassium permanganate solution to the rotted root areas, or wrap the leaf part with toilet paper and place it under weak sunlight for half an hour, using ultraviolet light, then plant it in treated substrate. After planting, put a transparent plastic bag over it and place it in a semi-shaded place, water less, and keep the potting soil slightly moist. At the same time, every 5-7 days, spray the leaf surface once with a 0.2% potassium dihydrogen phosphate aqueous solution to increase nutrients and promote rooting.

In this way, after about two weeks, new roots can grow. At this point, remove the bag and gradually transition to normal care. For the latter situation, the rescue method is: first rinse the base of the stem clean with water, then use a sharp knife to cut off the rotted part horizontally (the cut surface is required to be flat and smooth), then immediately apply sulfur powder or charcoal powder to the cut to prevent wound infection, place it in a cool, ventilated place, and after the cut surface is slightly dry, plant it in a pot of plain sand. Water once after two days, and afterward keep the potting soil moderately moist. Absolutely do not fertilize. Under a temperature condition of 20-25°C, after about 10 days new roots will grow around the cut, and after about 45 days it can be transplanted into a pot with new potting soil and gradually brought into normal care.

Stop Fertilizing Clivia

When the indoor temperature is higher than 25°C, fertilization should be stopped. This is because even if fertilizer is applied again, the rhizome will not absorb it. On the contrary, if the fertilizer ferments in the soil and generates high temperature, it can easily burn the fleshy roots. If more fertilizer was applied in spring, after summer begins you can also replace 1/2 of the potting soil from the upper part, and then replace it again after the Start of Autumn.
