Caring for hibiscus properly when the leaves turn yellow
One of the most common problems hibiscus growers face is that their hibiscus plants turn yellow and/or get pale and veiny leaves. Experienced growers are especially prone to taking the wrong approach to treatment when they see this happen to a hibiscus plant. This is because they have been successful with treating other plants that have the same appearance, but the causes are completely different because hibiscus have very different needs than most other flowering plants.
Pay attention to the temperature outside
Hibiscus grows best at temperatures that range from 15 °C to 32 °C, and this beautiful plant cannot tolerate low temperatures – it freezes below 0 °C. In the summer, your hibiscus plant can be outdoors, but as soon as the temperature gets close to freezing, you should not leave your hibiscus outside in the garden or on the terrace, but bring it indoors. Avoid the mistake of letting your plant freeze.
Your hibiscus needs sun: pay attention to the location.
Make sure your hibiscus needs plenty of sun. The more direct sun garden and houseplants get, the better they bloom. At least 6 to 8 hours of sun is optimal for good flowering, but you can also plant them in the shade: they will then bear fewer flowers during the summer. Afternoon sun is stronger than morning sun, so a proper location that is shady in the morning and sunny in the afternoon should produce more flowers.
Important tip : Do not choose a location for your plant that is sunny in the morning and shady in the afternoon.
Maintaining Hibiscus: Create watering schedule and avoid mistakes
When hibiscuses bloom, they need a lot of water. In warm weather, the plant needs to be watered daily. However, once the weather gets cooler, your plant will need less water outside or indoors. Water your hibiscus in winter, only when the soil feels dry.
Finding the right soil
Hibiscus does not do well when there is waterlogging and prefers moist, but well-drained soil. Loamy and sandy loam soils are usually the best. If your soil is too sandy, you can improve its texture by incorporating mulch or other organic matter.
Care for Hibiscus: Don’t forget fertilizers
Garden and houseplants need a lot of nutrients. If you do not fertilize them properly , you commit a big mistake. There are several ways to fertilize hibiscus. One option is to spread a layer of compost around the base of the plant in the spring. You can apply liquid fertilizer to your marshmallow in a pot. Be careful not to use too much fertilizer, as too much phosphorus will kill the marshmallow.
Watch out : you should stop fertilizing before the dormant season, otherwise it could cause frost damage to garden plants in winter.
Cut hibiscus – important for the appearance of the plant.
Pruning a hardy marshmallow in the garden is not complicated, but there are a few things you should know to keep the plant looking its best. Cut back any dead stems or branches to about 20-30 inches in the fall before applying a protective layer of mulch. Remove the mulch in the spring when you are sure there is no risk of heavy frost.
If branches are frostbitten during the winter, cut them back to the ground. When new growth begins, you can then prune and shape the plant as you see fit. Remember that perennial hibiscus is a slow starter, so don’t worry if there is no growth yet in the spring. It may take a number of warm days before the plant decides to sprout. Cut back the shoot tips when the plant reaches a height of about 15 inches. This will encourage the plant to branch out, resulting in a bushier plant with more flowers.
Remove wilted flowers throughout the season to keep the plant clean and encourage a longer blooming season. To do this, pinch off the old flowers with your fingernails or cut them off with pruning shears. Some perennial hibiscus species can self-seed. If this is the case, be sure to pinch off old flowers to prevent the plant from going to seed.
Successfully control pests
Take time to accurately identify the pest and then find the exact pesticide you need to get rid of it. Above all, it is very important that you use only natural means if possible to get rid of the pests. If you use pesticides on your marshmallow, you risk killing the beautiful plant.
