Caring For Your Hibiscus
These blooms thrive in temperatures between 60 and 80 degrees Fahrenheit. A growing hibiscus needs lots of nutrients in order to flourish. In the summer, you should use a high potassium fertilizer by either using a diluted liquid fertilizer once per week or a slow release fertilizer once a month. You have the option to add a high potassium compost to the soil as well.
Pro Tip: Worm castings are richer than regular compost, so think about adding these to your fertilizer! They contain potassium, phosphorous, nitrogen, humus, and other micro-nutrients that are beneficial to hibiscus.
Make sure to water your hibiscus daily too!
If you are worried about the extreme heat or want to see the vibrant blooms year round then you can plant these blooms in a container or pot. This will allow you to move your hibiscus around to the ideal locations or move it inside your home! The tropical hibiscus is the most popular variation for an indoor space! However, make sure your plant receives at least 6 hours of sunlight. These plants prefer a snug fit when growing in a pot or container, which means your plant should be slightly root bound. Only give your hibiscus a bit more room when you choose to repot.
As always, make sure your hibiscus has adequate drainage!
Pro Tip: Although hot, humid conditions are ideal for tropical hibiscus, you may want to provide a little afternoon shade during extreme heatwaves.
