Over-watered Climbing onion will develop yellow leaves. It is normal for yellow leaves to develop when Climbing onion has reached the end of their blooming period. However, if the leaves turn yellow before the flowers have bloomed, it is a sign of over watering. If you water your Climbing onion too much, then try to ensure there is adequate drainage and do not give it any more water for a couple of days. You can mix some sawdust into the soil to absorb the moisture. If the situation continues to deteriorate after controlled watering, consider whether the seedpods have rotted. Try digging them up and checking whether they have changed color and become soft. Once you find severe decay, then you should promptly clean out these seedpods. Under-watered Climbing onion actually looks similar to over-watered Climbing onion with their yellow leaves. However, the stems will also droop and leaves will look smaller and will curl. You may also see some brown patches appear. If you have given your Climbing onion too little water, then do not panic. It has a level of drought tolerance. Once you have realised, give it a good drink but do not saturate the surrounding soil. Just make sure it is moist.But do not give them too much and overwater them, you just need to let the soil to be mosit. Extended periods in water can lead to root rot and fungus growing on the bulb. The fungus can cause serious damage to the bulb which is noticed through spots that appear on the leaves and buds. The tips of the leaves may also discolor and die.

It very much depends on the location and the current growth state of your Climbing onion. Once you have planted your Climbing onion, water them well once and then leave them. That initial watering will kick start their growth, but after that you can leave them be until you see shoots appear. If your Climbing onion is in a pot, you will need to water them when the top 1-2inch feels dry. Container plants can dry out faster than bedded plants, so ensure that the soil is damp. If your Climbing onion is planted outside in flower beds and borders, they will not require additional water if it has rained during the week. The Climbing onion has some drought resistance, slight dryness can be recovered quickly after watering, but excessive watering can directly cause the plant to die once the seed ball rots, you need to stay cautious about how often you water the plant.

When your Climbing onion is growing, you will need to water about once a week. As the temperature rises, the soil will dry out faster and you will need to increase the frequency of watering. A dry soil environment will be more friendly to your Climbing onion than an excessively wet soil environment. Climbing onion will become dormant during summer and the above-ground parts will completely dry up and die after dormancy,. if you planted it outdoors, you shouldn't need to water it. Moreover, if there's plenty of rain in your region, you should consider digging them out to protect the buds from rot due to too much water. If you planted it in pots, you should stop watering your Climbing onion completely after the dormant part dries out. After the above-ground part dries out completely, dig up the buds and store them in a cool location or stop watering them completely to keep the soil dry. Resume watering until the next sowing season. Or keep them in the soil in a cool location until the next growing season.

Monitor your containers for moisture, moving them to a sheltered position if they become sodden or waterlogged. Allow them to dry out and return them when the weather improves. Outdoor planting often takes rainwater into account, and when planting, you should consider planting the plants in well-drained soil to avoid waterlogging and decay. Whether grown indoors or outdoors,before the buds grow out after planting the bulbs, they need very little water and you should try to let the soil dry out completely before watering in small amounts, which will effectively avoid bulb rot. You should wait to water them regularly until they grow new shoots. Your Climbing onion is more susceptible to rot indoors in low light and poor ventilation. Therefore, you need to be careful when watering indoors and make sure that a lot of the soil is dry before watering. If you can keep it moist for a long time indoors, you also need to consider if your Climbing onion is in an unsuitable location. Whereas outdoors, good ventilation and plenty of light will be relatively safe.

Climbing onion should get at least 6 hours of sun per day, and preferably more. An actual minimum number of hours can vary depending on the intensity of sunlight and other environmental factors, but it is unlikely that the Climbing onion will get too much sunlight. They do fine with up to 14 hours of sun per day.

Climbing onion needs a lot of bright sunlight. As full-sun plants, they can thrive when given direct light or bright indirect sun. Some types may be able to survive with partial sun, but more sunlight is generally better.

Climbing onion usually grows in some of the hottest, sunniest places in the world and is well adapted to that kind of environment, so it does not need to be protected from the sun. However, you should be careful about making a sudden move into a very sunny location if your Climbing onion is not used to it. Plants need time to adapt to different conditions, so start by moving this plant into the sun for a couple of hours at a time each day, then gradually lengthen the amount of sun exposure. Once adapted, most types of Climbing onion will be fine in full sun and don't need protection.

Without enough sunlight, Climbing onion will fail to thrive and grow. Common symptoms of inadequate sunlight include pale coloring, wilting leaves, and leaf drop. Climbing onion may also exhibit etiolation (also called legginess). This condition occurs as the plant attempts to stretch toward the light source, leading to a sparse appearance and weak stems.

Climbing onion may develop shades of red, pink, or orange as a means of protection from excess sunlight, so many people like to cause mild sun stress to these plants during the summer. This is not harmful, and they will revert to their normal coloring when light levels decrease from autumn to spring. If moved too quickly into direct sun, Climbing onion can suffer from sunburn. This looks like white or brown spots on the uppermost leaves that have been exposed to the most sun. A sunburned plant should be moved to a shadier location and watered if needed. Sun-damaged leaves can be removed, and should be replaced by new growth over time.

As with most plants, younger Climbing onion will be more sensitive to strong sunlight and heat than a mature specimen. They should also be protected from direct sun immediately after being transplanted, either by a shade or by keeping the container in a shadier location until the plant is established and putting out new growth.

It is best to water Climbing onion in the morning, particularly during the summer months. If water sits on the leaves or in the crown of the plant, it can burn the plant when the water heats up. It’s also best not to water in the evening, since cooler overnight temperatures slow evaporation and fungi or bacteria can develop in the moist conditions. Climbing onion grown in pots should be rotated occasionally to keep them growing symmetrically. Plants will normally grow toward the light source, so they can develop much more quickly on one side than the other if they are not rotated. If Climbing onion is allowed to get dusty, it will not be able to access sunlight to create energy. The dust acts as a barrier, so the plant may show signs of inadequate light even if it’s in a sunny location. Keep the leaves and stems clean by wiping them periodically with a damp cloth to avoid this issue.

To create the best possible environment for Climbing onion, you’ll want to grow your Climbing onion in temperatures between 60-75℉ (15-25℃). They can tolerate marginally higher and lower temperatures, but this range will help facilitate optimal growth. Climbing onion that experience temperatures below 40℉(10℃) or above 95℉(35℃) will go into a state of dormancy, halting their growth. Staying above 95℉ (35℃) for anything other than a short period can damage these plants; enough time in high temperatures may kill them entirely.

Climbing onion do require different temperatures to enter their different phases of life, primarily the dormant phase they reach during summer and their growing phase during the winter. Climbing onion need cooler temperatures to actively grow, but not too cold; anything below 40℉(10℃) will push them into a state of dormancy regardless of season. High temperatures can also induce a dormant state, restricting growth and reducing the plant's watering needs. Too much watering during dormancy can drown the plant and cause root rot, so make sure to only water the soil when it feels dry.

Tip #1: Don’t Over-Water When Temperatures Are High It may seem counterintuitive, but Climbing onion actually need less water during summer. To see if your plants have enough moisture, check the soil by putting your pointer finger two inches (5 cm) below the surface and feeling to see if it's dry. If it's already wet and you continue to water it, you can cause the roots of your plant to rot. Tip #2: Don’t Panic If Temperatures Occasionally Get Too High or Low While you’ll want to keep your Climbing onion in the optimal temperature range as much as possible, they won’t die instantly if temperatures drop or rise. Climbing onion have even been known to survive at temperatures below 0 ℃ for small amounts of time. Temperature fluctuations will usually cause your plants to enter a state of dormancy, going into survival mode and utilizing less water. You’ll want to return them to the correct range as soon as possible, but don’t think all is lost if the temperature suddenly shifts. Tip #3: Avoid Placing Your Climbing onion in Extreme Heat When exposed to very high temperatures for extended periods of time, Climbing onion will begin to change and experience damage. The changes may seem aesthetically pleasing at first, with the leaves changing into muted shades of red, yellow, and orange. But eventually they will begin to wither as the plant succumbs to sun damage, eventually stopping it's growth entirely and causing your Climbing onion to die.

Climbing onion actively grow in winter, though their flowers won’t appear until the warmer temperatures of spring. If you are planting these succulents indoors, the seasons won’t affect their temperature requirements very much. The focus will be more on the ability for the plants to get the right amount of sunlight. Winters can make it more difficult for Climbing onion to get the right amount of light, while summers can provide an overabundance. Too much sunlight can damage the leaves and stems of the plant, slowing their growth or halting it entirely. Keep your Climbing onion in an area with bright but indirect light to see the best results.

If you are growing your Climbing onion indoors, you’ll want them kept in an area of your home with a climate control system. This system can be an A/C unit if you live in a warmer region or a heater if you live in a colder region, though the air from either should not come directly in contact with the plants. Try to have as much natural air as possible without drastically shifting the surrounding temperature. You’ll also want to be mindful of the sunlight they experience, keeping them in rooms with ample, but indirect, window lighting. If your Climbing onion is outside, you’ll want to control the temperature by positioning it for optimum sunlight. This means avoiding the direct sunlight and heat of midday; Climbing onion is full sun or partial shade plants, dappled sunlight filtered through a tree, plant, or fabric structure is the best. An overabundance of sunlight can also expose them to high temperatures, putting them at risk of dormancy and damage.

Fertilizing Climbing onion adds nutrients to the growing medium. Even though it does store water and nutrients, applying plant food during the growing season helps support healthy growth. Fertilizing can also encourage mature specimens to produce blooms in the growing season.

While all plants benefit from additional nutrients, Climbing onion only needs a light dose of fertilizer during the growing season. The frequency of fertilization should be 1-2 times a year. It is suggested to fertilize your Climbing onion in the spring and autumn, but not in winter&summer when it is dormant. Be careful with repotted plants, you will want to reduce the amount of fertilizer. It’s also a good idea to wait a couple of months after repotting before you start applying fertilizer.

Like most plants, Climbing onion has a dormancy period and it is when you want to stop the applications of fertilizer. In the summer and winter, the plant ceases growing, and it is when you want to stop applying fertilizer. It’s also a good idea to cease fertilizing for the first couple of months after repotting in the spring.

It’s best to use a liquid plant food formulated for succulents and cacti when you are fertilizing Climbing onion. Dilute the fertilizer with water to half-strength. You do not want the fertilizer building up in the soil. Apply the fertilizer to the base of the plant and water thoroughly, ensuring any excess moisture drains from the container or seeps into the ground.

It is easier to use liquid plant food when you are fertilizing Climbing onion, but granules are another option. Follow the directions on the packaging, making sure you dilute liquid fertilizers to half-strength. Whether you are using granules are liquid plant food, always apply it to the soil. Cover the granules with a thin layer of soil and water regardless of the type of plant food you are using.

Over-fertilizing Climbing onion is a common problem with new and experienced gardeners. The plant has low nutritional needs and it’s easy to apply a little too much fertilizer. Over-fertilizing Climbing onion can burn the plant’s sensitive roots resulting in its slow decay. Without its root system, the plant cannot absorb nutrients and moisture.
