  1. Prepare the soil before planting the hibiscus seeds or stem cutting. To do so, make sure to choose an area that has moistened the soil with a pH level between 6.8 and 7.2.
  2. You can also use Garden Soil sold in the market and mix it with the natural soil to prepare an optimum soil condition for your plant. Or else, you can choose to mix in 2″ of natural compost before planting.
  3. Also, dig a hole twice as wide and just as deep as the plant’s root system if you plan to grow your hibiscus from stem cutting.
  4. If growing from a stem cutting, take 5” – 6” inch-long cutting and dip it into root hormone. Then, plant the cutting’s 3” into the soil amended with peat moss or vermiculite. Place the container in a partially shaded area. And once cutting starts producing new leaves, you can transplant it.
  5. If you want to grow your plant from seeds, you should sow the seeds thinly in a starter tray, about 1/4″ deep, using standard potting soil. Then, gently water the seeds and press the soil. Be cautious not to suffocate the seeds. Once the seeds grow their third set of leaves, you can transfer them to your garden.
  6. When growing Texas Star Hibiscus in your garden, it would be better to maintain a 3-4′ spacing. Doing so would eliminate the chance of overcrowdedness.
  7. Make sure to water your plant throughout the growing months. You must water your newly grown hibiscus every couple of days for the first few weeks after planting.
  8. It is also advisable to use fertilizer during the spring and summer seasons- mix in about 1”. However, avoid this step once autumn months hit, as Texas Star is a deciduous plant and would start shedding leaves post-summer months.
