Hardy Hibiscus: An Overview
Hibiscus is a flowering plant that can be found in many parts of North America. Hardy hibiscus is a type of hibiscus that can be planted in the spring when there is no risk of frost. The plants will grow quickly and erupt each summer with blooms the size of dinner plates. Each bloom lasts only a day or two, but they are quickly replaced by new blooms.
Though hardy hibiscus can be grown indoors, it is best suited for the landscape where it will last much longer than if it were cut and placed in a vase. Hardy hibiscus comes in many different colors, making them a perfect addition to any garden or landscape.
History of Hardy Hibiscus
The history of hardy hibiscus is a relatively short one, but in that time they have become very popular flowers. Hardy hibiscus was developed in the 1950s by cross-breeding different native species of hibiscus. Robert Darby was one of the first modern cultivators of hardy hibiscus and he is credited with helping to spread their popularity. Sakata Seed Corporation started to hybridize hardy hibiscus in Japan in the 1960s and this led to a wider distribution and increased popularity of the flowers.
Hardy Hibiscus Planting and Care Requirements
Hardy hibiscus is a type of tropical flower that can be grown in many parts of the United States. They require plenty of sunlight and warm temperatures to thrive, so they should not be planted in shady areas or areas that experience cold winters. Hardy hibiscus needs regular watering; they should be fertilized monthly with a balanced fertilizer, and they need plenty of space. They should be planted in a location that receives plenty of sunlight.
Seed Planting
When planting hardy hibiscus from seeds, there are a few things you need to keep in mind. First, the best time to plant them is three months before the last average frost date if you are located in Zone 6 or lower.If you live in Zone 7 or another warm area, you can start your seeds inside one to two months before to the latest average date of a frost, or you can sow them directly in the ground once the threat of a frost has passed. Secondly, make sure to soak your seeds overnight before planting and to set them about ½ inch deep into the soil. Before transferring them into your garden, spend about 30 minutes of the first day bringing them outside, and then increase that time by about an hour each day for the next five days.
Choosing and Preparing a Location
When choosing a location to plant your hardy hibiscus, it is important to take into account the soil type and drainage. Hardy Hibiscus does best in medium to wet soil that drains well. They will not do well in sandy, dry, or poor-draining soils. If the soil in your garden is sandy or drains poorly, mix in a few inches of organic compost before planting your flowers. In cooler climates (zones 4 to 6), hardy hibiscus will do best when planted near the south-facing wall, where they will receive plenty of sunlight and are protected from the wind.
Watering
Watering is one of the most important aspects of taking care of your hardy hibiscus plants. You want to make sure that the plants are getting enough water, but you don’t want to overwater them. Hardy hibiscus plants typically need deep watering at least once a week. They will let you know when they need water by wilting.In comparison to a huge, leafy plant, a little plant with fewer leaves requires less water.
Light
Hibiscus plants need at least six hours a day of full sun to bloom to their potential. If you live in a hot and dry climate, provide your hardy hibiscus with occasional relief from the hot afternoon sun—grow other leafy plants nearby to cast a shadow, or Pick a spot for your plants that has some light shade. Indoor hibiscus plants should be placed close to a sunny window, especially one that faces the southwest. If that isn’t enough light, you can add grow lights.
Soil
Hardy hibiscus needs organically rich soils in order to grow well. Before planting, amend the area with some organic compost to provide nutrients to the soil. Hardy hibiscus is a wetland plant and therefore needs moist areas to grow. They can be planted around water features and ponds where they will receive the necessary moisture.
Temperature and Humidity
Temperature and humidity are two important factors to consider when growing hibiscus plants. Hibiscus plants flower best in temperatures that range from 65 degrees Fahrenheit to 75 degrees Fahrenheit, so try to keep your home within that range. Additionally, be mindful that low humidity can dry them out quickly, so you may need to water them more frequently if the air is dry. A small space humidifier will also raise humidity levels in your home, which can be helpful for hibiscus plants.
Fertilizer
Fertilizing your hibiscus plants is important for their health and growth. You should feed them with a diluted liquid fertilizer once a week or a slow-release fertilizer three times a year. Make sure to include early spring, after the first round of blooming, and mid-summer in your fertilizer schedule for best results.
Pruning Hardy Hibiscus
Pruning is an important part of taking care of any plant, and the hardy hibiscus is no exception. In order to promote healthy growth, it is necessary to prune the plants to the ground during the fall season. This will help them grow back stronger and bushier in the spring.
Overwintering: Cold Weather Care
When winter approaches, it is important to take steps to protect your hardy hibiscus plants from the cold. One way to do this is by applying mulch around the plants after you have pruned the flowers back. You can use wood chips, leaves, or straw as mulch. Another thing you can do is be patient; hardy hibiscus usually sends out their first signs of new growth in May or June.
Pests and Diseases
There are a few pests and diseases that can affect hardy hibiscus plants. To keep deer away, fence around your plants. Aphids can be a problem, so apply an insecticidal soap to infected plants on a weekly basis. Hardy hibiscus can develop fungal infections, including rust, leaf spot, and botrytis blight, so avoid getting the leaves wet when watering.
Hardy hibiscus varieties
There are many different hardy hibiscus plants that vary in size, shape, and color of blooms. Some popular varieties include:
– Lady Baltimore (tall and wide variety with light pink flowers with a red center)
– Robert Fleming (compact variety that is 2 to 3 feet tall and wide at maturity; huge blooms are a deep, velvety red)
– Summerific Perfect Storm (compact and well-branched variety that produces dark purple foliage; grows to be 3 feet tall and 4 feet wide; large 7-inch whitish-pink flowers have a red eye)
Propagation Hardy Hibiscus
There are a few different ways to propagate hardy hibiscus. They can be propagated by seed, stem cuttings, or crown division. In order to propagate them by seed, you will need to sow the seeds in a moist, well-drained soil. The seeds should then be planted in a warm, sunny location. Hardy hibiscus can also be propagated by stem cuttings or crown division. To propagate them by stem cuttings, you will need to take a cutting from the desired plant and place it in water until it has rooted. To propagate them by crown division, you will need to divide the plant into two parts and replant each part separately.
Growing Hardy Hibiscus From Seed
Growing plants from seeds is an excellent way to get a lot of plants at low cost. This is because you can purchase a packet of seeds for much less than you would pay for a single plant. Additionally, many plants can be grown from seeds very easily, so it’s a great way to get into gardening. However, if the seeds are from hybrid plants, it’s impossible to know what you’ll get. This isn’t necessarily a bad thing, if you’re looking for variety, but it can be frustrating if you’re expecting all the plants in your garden to look the same.
Growing Hardy Hibiscus From Cuttings
There are a few things you need to do in order to propagate hardy hibiscus from cuttings. First, you need to moisten the end of the cutting and then dip it in rooting hormone powder. Next, poke a hole in the growing medium and insert the cutting. Finally, tamp the planting medium around it so that it is secure. After that, place the cutting in a warm area with consistent temperatures or a greenhouse with 50-60 percent humidity. Make sure to keep the cutting moist at all times; if it dries out, it will die.
From Crown Divisions
When you are dividing hardy hibiscus, it is best to do so in the spring or early fall when the soil is still moist. You should avoid breaking larger primary roots when teasing roots away from the plant. If you have diseased or dead root mass, trim it away and replant or pot the division and fertilize with transplant fertilizer.
Hardy Hibiscus Winter & Cold Weather Care
In order to protect your hardy hibiscus plants from the cold, you can apply about 3 to 4 inches of fresh mulch after you’ve pruned the flowers back. Any type of wood chips, leaves, or straw can be used to shield the roots from the cold and create a warmer environment. It’s important to be patient; hardy hibiscus usually sends out their first signs of new growth in May or June.
Hardy Hibiscus Problems: Pests and Diseases
In addition, there are a few things you can do to protect your hardy hibiscus from pests and diseases. For one, deer can be a problem, so fence around your plants to keep them out. Aphids can also be a nuisance, so apply an insecticidal soap to the infected plants on a weekly basis. Additionally, hardy hibiscus can develop fungal infections, including rust, leaf spot, and botrytis blight. To avoid getting the leaves wet when watering, try to water in the morning or evening when the leaves are dry.
