Due to its nature, it prefers moist, well-drained soil, however, it is very tolerant of various growing conditions, including periods of drought as well as exposure to pollution. This aspect makes it excellent for urban gardens.

Annual: does not tolerate cold temperatures. It has glossy deep green leaves, mostly yellow, pink, or red flowers, both single and double.

Perennial: dies back in the fall and returns the following spring. It is a shrub that flowers in red, pink, or white. With leaves of a very dull green color.

Rose of Sharon can be planted during the spring or fall. Generally, they tend to sprout a little late in the spring, so don’t be alarmed if you notice that your planting looks a little dull at the beginning of the season.

Once the planting process is complete, you can enjoy this new addition to your personal garden for a couple of years. To do the planting, try to do the following:

1- Determine the planting site. Make sure that it is not surrounded by other plants that prevent it from growing. The soil must drain very well.

2- Dig a hole. Dig a root system depth at least 2 to 3 times wider than the repot pot.

3- Repot the shrub. Gently place the container you bought it in in the ground. Carefully remove it and place it upright in the soil. Before filling the hole, add a quantity of water and let it soak in completely.

4- Refill the hole. Use the excavated dirt to backfill the hole. Press gently to stabilize it and water it again until the soil around it is soaked.

5- Apply compost or other fertilizer. Put it around the stem in an area large enough to cover disturbed dirt. Do not touch the stem directly.

Rose of Sharon Planting Guide Tips and Recommendations

All varieties of Hibiscus syriacus typically bloom around August (northern hemisphere), with a blooming period of at least three weeks, which could be extended if the weather is warm. When grown in the right position it will take care of itself without demanding a lot of attention.

Take into account some of the best tips and recommendations that we share with you below so that you can take advantage of them every year:

1- How it likes full sun. In case you are in a very hot summer area and strong sunlight, provide shade during the hottest part of the day. If, on the other hand, there is no direct light, use supplementary lighting.

2- Take a distance of at least one meter between each hedge to allow ample growing space.

3- Before planting, if the roots are tight and twisted cut them a little to loosen the root ball.

6- Use peat moss in the soil to increase drainage.

7- Avoid pruning during the summer.
