Solutions for Yellowing and Blackening Freesia Leaves and Methods for Dwarfing

When it comes to freesia, many people who are unfamiliar with it may assume it is a type of orchid, but it actually is not! Freesia is also called xiaocanglan and belongs to the Iridaceae family. Freesia has an orchid-like posture and a captivating fragrance, which is how it got its name. Freesia is beautiful in appearance and is very suitable as a home potted plant, but some flower enthusiasts find that the leaves of the freesia they grow turn yellow and black. How should this be solved?

What to do when freesia leaves turn yellow and black

1. Water-induced yellowing: Yellow leaves on freesia may be caused by overwatering, with water accumulating in the pot leading to withered and yellow leaf tips. The main signs are dull yellow, lusterless young leaves that wilt and droop, while old leaves show no obvious change; the stems are thin and long, yellow-green, and new shoots are short, shrunken and do not grow. When overwatering is severe, take the plant out of the pot and place it in a cool, ventilated place, then put it back in the pot after the potting soil has naturally dried.

2. Drought-induced yellowing: When the plant lacks water and the soil is dry, the leaf edges become withered and dry, the old leaves turn yellow and fall off from the bottom up, and the new leaves grow normally. Be careful to water thoroughly, check the moisture of the potting soil frequently, and keep the potting soil moist. When the temperature is high and water evaporates quickly, you may appropriately sprinkle water to increase air humidity.

3. Light-deficiency yellowing: Most flowers grown at home are placed on windowsills or balconies, but many households place them beside TV cabinets or coffee tables for aesthetics. The plant then cannot get enough light, making it difficult to form chlorophyll, and the leaves of the whole plant gradually turn yellow and fall off. Move the plant into the sunlight to supplement light.

How to dwarf freesia

1. Control the surrounding environment: Specifically, three main elements need to be controlled, namely: water control, fertilizer control, and soil control. Among these three, fertilizer control has a relatively obvious effect. In this way, its growth rate can be effectively inhibited, thereby achieving the goal of making the plant shorter.

2. Pinching: We all know that the main stem of a plant generally grows relatively tall first, which can be very troublesome. Therefore, to solve this problem, when the main stem has grown to a certain height, we can pinch it to let the side branches grow and inhibit the growth rate of the main stem. When the side branches have grown very long, they can be pinched back, and the treatment can be repeated.

3. Pruning: This can be done in all four seasons. Cut off excess branches, especially those that are too long. In this way, the growth of its branches can be promoted. Through continuous pruning, the goal of dwarfing it can be achieved.

4. Use chemicals: When potting in autumn, mix the chemical evenly with water. Then, soak its bulbs in it for 15 to 20 hours. After that, take them out, rinse them briefly, and they can be potted.

What to do if freesia grows leggy

1. Watch the temperature and keep equal spacing

The planting time should be determined according to the local temperature. Usually, plant when the temperature during the day is 20°C. If planted too early, freesia sprouts quickly and is prone to leggy growth. If the temperature at planting time is higher than 20°C, the bulbs can be buried deep and not watered for the time being; after the temperature drops, water and manage them normally.

When planting, arrange the freesia bulbs at equal distances. Place smaller bulbs on the outer edge and larger ones in the middle. Larger bulbs grow rapidly and are prone to lodging, while the small plants on the outer edge can serve as support.

2. Plant deeply and apply enough base fertilizer

When planting freesia, it is best to choose an orchid pot with a depth of about 10 cm. Planting freesia in a deep pot makes the plant grow tall and upright; otherwise, it looks listless and is prone to lodging.

In addition, apply enough base fertilizer when planting, adding sufficient plant ash or soybean cake to the soil. During the subsequent growth period, there is no need to apply fertilizer frequently; each application can be a dilute liquid fertilizer.

3. Control water during the growth period

After planting, water thoroughly and place the potted plant in a cool place. Before sprouting, water according to the principle of "dry-wet alternation"; after sprouting, gradually increase light. Heavy watering and high temperatures will cause freesia to grow too quickly, with weak, thin, and elongated seedlings. If this happens, you may prune appropriately. When pruning, do not cut straight across; maintain a certain slant so that the plant's growth tends to look natural.

Is freesia poisonous?

First of all, let me tell everyone that freesia is non-toxic. Friends who like freesia can plant it with peace of mind and do not need to worry that its fragrance will affect their health. Freesia is not only non-toxic, but is also a widely used winter ornamental flower, and many horticultural varieties have been developed so far. It is commonly potted or its flower stems are cut and placed in vases to decorate rooms, making it an ideal flower for embellishing living rooms and studies.

Through the above content, I believe everyone has gained some understanding of freesia care techniques. Although freesia is not as delicate as orchids and does not require meticulous, patient care, it still requires mastering the correct care techniques. If cared for improperly or left unmanaged for a long time, problems are very likely to occur!
