If you plant the hibiscus in pots, you can move them to shadier or sunnier areas if you notice that they’re getting too much or too little sun.
If you’re growing your hibiscus in a pot, make sure there are drainage holes in the bottom so that the soil doesn’t get too wet and lead to root rot.
Make sure to get a fertilizer that’s low in phosphorous, such as 20-5-20, as high amounts of phosphorous may lead to smaller blooms.
