Have you ever wondered how to cultivate bare root hibiscus? These beautiful flowers come in different colours: white, pink, peach, orange, yellow, red, or purple. Bare root hibiscus offers several benefits, but many gardeners in the UK are unfamiliar with this starting medium.
What You Need to Know About Cultivating Bare Root Hibiscus
UK gardeners are used to planting small liners, but bare root hibiscus is grown in the field and offers a larger yield. A larger yield means you’ll enjoy faster turnaround times and more high-quality flowers per container.
If you’re interested in how to cultivate bare-root hibiscus, here are seven things you need to know:
Tip #1: Potting and Time of Planting
It would help if you placed the bare root hibiscus in the pot as soon as you get it. Plant one bare root plant in every three-gallon container in peat moss or bark planting medium with an ideal pH level of 6 to 6.5. Place them outside once the last frost date has passed and made sure to install drip irrigation. Make sure that you avoid placing the pots too close to one another.
Tip #2: Fertilizer
If you want your hibiscus plants to grow fast, you’ll need to apply fertiliser. Feed the plants with liquid fertiliser of 150 to 200ppm nitrogen during every irrigation, or you can add control release fertiliser when you pot it. Make sure not to add too much fertiliser because too much phosphorous can kill your plants.
Tip #3: Watering
Your hibiscus plants thrive best in a moist potting medium. If it’s too dry, the leaves will fall, and your cuttings will look like sticks. When this happens, don’t throw your cuttings away. It will re-bud, but make sure that you don’t overwater or underwater your plants. Don’t let water sit in the container; otherwise, it will lead to root rot. Make sure to use a pot that has proper drainage.
Tip #4: Temperature
Hibiscus plants grow best in warmer climates, with a temperature of 65 to 67 degrees F or higher. If you live in colder areas of the UK, you can expect a drawn-out growing season and chlorotic leaves. It’s better to place your plants outdoors during the summer but make sure they’re getting enough water.
Tip #5: Diseases and Pests
Japanese beetles, spider mites, whiteflies, and sawflies are some of the pests that attack your hibiscus plants. Ensure you check your plants regularly for these harmful insects and apply appropriate measures if you spot one. As for diseases, thankfully, blight is not standard on hibiscus plants.
Tip #6: Lighting
For your hibiscus plants to produce flowers and leaves, you’ll need to expose them to high light. For example, some hibiscus variants will grow greener if you grow them in a greenhouse. It’s best to grow them in full sun or outdoors or if you grow them in a greenhouse, make sure you have high light intensities. Hibiscus flowers need long days for flowers to bloom.
Tip #7: No Forcing
Many gardeners in the UK want to force hibiscus, but UK experts do not recommend it. Besides the fact that forcing them to bloom is expensive, these flowers need long days to bloom. Experts recommend naturally grow bare root hibiscus.
Why Plant Your Hibiscus Flowers in a Semi-Pro Greenhouse?
As mentioned, hibiscus plants need to grow in warmer climates, and they also need longer days to bloom. If you live in colder regions of the UK, it’s better to cultivate your plants in a greenhouse. Here are some of the reasons why:
Protect your plants from harmful insects
Hibiscus plants are susceptible to insect attacks from whiteflies, sawflies, and more. Keeping them inside. An enclosed space reduces the chances of attracting these pesky insects.
Greenhouses come in different sizes
When people think of greenhouses, they instantly think of large, glass wall enclosures. However, not a lot of people know that greenhouses come in different shapes and sizes. You don’t always need a gigantic polytunnel unless you’re running a commercial business. If you want to grow seasonal fruits, vegetables, flowers, etc., you can still benefit from semi-pro or mini-greenhouses for a fraction of a cost.
Semi Propolytunnelis an excellent option for those with limited spaces
If you’ve wanted to grow your produce, but you don’t have enough space, a semi-pro polytunnel is the one for you. Its compact size can be placed on balconies, patios, decks, and more. Even though they’re smaller, semi-pro greenhouses provide the same benefits as regular-sized greenhouses.
Keep your plants safe from harmful weather
Snow, frost, ice, heavy winds, and rains can quickly wipe out your flowers and crops. Protect your plants from bad weather conditions by placing them inside a greenhouse. Once the weather warms, you can transplant them outside if you want to, but you can keep them there until the spring season begins.
Grow crops and plants any time
With a greenhouse, you don’t have to wait before planting your crops. You’ll be able to grow them before the cold season begins in your area of the UK. You can keep them inside the polytunnel until the weather becomes more manageable, and you can place them outside.
