Hibiscus is a tropical shrub with large, brightly colored flowers. This plant likes warm temperatures and usually doesn’t survive frost – if you live in a cold climate, it’s a good idea to grow it in a pot. When grown outdoors, the brightly colored hibiscus flowers often attract hummingbirds and butterflies. You need to make sure the plant receives many hours of direct sunlight each day for it to bloom from spring through fall.
Steps
Caring for hibiscus grown indoors
- A mixture of 1 part coarse peat, 1 part bark humus and one part rotting manure with some light gravel and vermiculite is also an excellent soil for hibiscus. [2] X Research Source
- Wait for the roots to absorb the excess water, but be sure to empty the water if there is still water in the tray after 12 hours. [4] X Research Sources
- Plant roots can rot if over-watered, so you should always test the soil before watering.
- When there is enough sun, hibiscus plants will bloom from spring until fall.
- You can also make a dilute solution of a water-soluble fertilizer (half concentration or less) and apply a small amount to the plant each time you water it. [9] X Research Source
- Avoid over-fertilizing, as too much phosphorus can kill the plant. [10] X Research Source
Growing hibiscus outdoors
- Hibiscus cannot survive frost or freezing temperatures.
- To improve drainage, you can mix in organic materials such as well-rotted manure, compost or mulch.
- You don’t need to add anything if the soil is well drained. [14] X Research Source
- Water thoroughly after planting.
- Plant the hibiscus plants about 90cm – 180cm apart.
- Test the water before watering the plant. Hibiscus does not like cold water, so you should use warm water, but remember not hot.
- Hibiscus plants need to be watered at least 2.5 cm per week. [17] X Research Source
- This plant likes rain water, but you can also use tap water.
- Do not use chemical fertilizers to fertilize hibiscus plants.
- If you can find a fertilizer that’s really low in phosphorus, like 10-4-12 or 9-3-13, use that.
- Avoid over-fertilizing, as too much phosphorus can kill the plant. [19] X Research Source
- Avoid insecticides containing imidacloprid, as this can make the infection worse for red spiders.
