How to Grow Hibiscus in Your Yard or Garden
When and Where to Plant Hibiscus
Growing hibiscus is an excellent way to bring vivid colors and exotic blooms to any yard or garden. To ensure success, it’s important to determine the ideal location for your hibiscus plants.
Hibiscus plants can be purchased from local nurseries or online garden centers. You can also start new plants from cuttings of mature plants.
Ideal times for planting hibiscus are when both soil temperatures and air temperatures rise above sixty-five degrees Fahrenheit. So don’t plant until after your last spring frost date.
If you’re planting in containers, select a pot large enough to accommodate mature roots, with several drainage holes at the bottom.
When planting outside in the garden, make sure you choose a spot with full sunshine exposure. Hibiscus need at least 6 hours of full sun, but will do better with at least 8 hours.
Less sun equals less flowers- so plant them in the sunniest place you have. The plants might sprawl more and have too-tall stems when they don’t get enough sunlight too.
Hibiscus isn’t too picky about their location. They can thrive in many soil types. You should dig in plenty of organic matter and compost before planting.
While they can handle some wetness, they don’t like to sit in puddles, so make sure your soil has fairly good drainage.
How to Plant Hibiscus
Planting your own hibiscus can be a rewarding experience and relatively easy to do.
While you can start them from seed, you’ll get quicker results if you buy young plants from a nursery.
Use a shovel to dig holes about twice the width and depth of your po.
Plant the potted hibiscus so that the stem is at the ground level.
Once planted, give your hibiscus plant a deep watering to give it a great start.
Water frequently that first week to ensure the roots recover from transplanting.
How to Care for Hibiscus
Caring for hibiscus plants is not a difficult task, but there are some important steps to follow in order to ensure your plants stay healthy and vibrant!
Hibiscus needs lots of water, especially when they are young and just getting established. Water at least 2-3 times a week the first couple months.
Adding mulch around the plant can help conserve moisture- as well as protect the roots in the winter.
Once the plant flowers, remove any spent flower to encourage more blooms.
Perennial hibiscus will die back each year and you can cut the stems to the ground when this happens.
Apply compost or fertilizer in each spring to encourage new growth and blooms.
Troubleshooting: Hibiscus Pests & Disease
Though hibiscus is easy to grow, it does have a few pests that can cause problems.
Common hibiscus pests include:
- Japanese Beetles
Soap and water or insecticidal soap can help with many of these pests. Or you can use a Neem Oil spray.
Encouraging beneficial insects, such as ladybugs, can help control many of these pests as well.
Diseases are usually caused by fungi that infect the stems and leaves
To help prevent pests and diseases in the first place make sure to give your hibiscus adequate space for air circulation, avoid overwatering, and be sure to clean up any plant debris that could contaminate the soil.
