The deciduous shrub produces flowers in summer and fall, making it a perfect choice for landscaping. You can also see the plant in urban areas since it is quite strong and not affected by pollution. Unfortunately, the rose of Sharon is toxic to dogs and cats. If your furry friends eat flowers, they will get sick and vomit. So keep them safe and away from this plant.

Growing Rose of Sharon

Rose of Sharon is primarily an outdoor plant, and you have to select a suitable spot for it in your garden. This shrub needs light, so find a corner that can provide four hours of sunlight every day. Partial shade works well too. The plant loves warm temperatures, but it can adjust to various weather conditions. So don’t hesitate to give it a try even if you live in a place that has cold winters.

While the majority of hybrid rose of Sharon species are seedless and will not sprout randomly in your yard, you might end up with a couple of unexpected plants near the main bush. You can remove them if you feel like they do not fit in your landscaping. But there is always another option – carefully remove the young plants and share them with your friends.

As previously mentioned, the rose of Sharon can grow in a variety of soils. But there is a chance it will not thrive in sand or clay. Therefore, go for soil that is rich in organic matter. Keep the ground moderately moist at all times, but don’t overwater the plant. Rose of Sharon can survive short droughts, so if you notice that the leaves are turning yellow, ease up on the water.

Using fertilizer is recommended if you want to have a stunning plant. So once you pick the spot for the rose of Sharon, and dig up the hole, make sure you add some of it into the soil. Water it well to settle the ground and avoid air pockets. Remember to fertilize before each growing season.

Moderation is crucial regarding fertilization. If you overdo it, your rose of Sharon might end up with lush foliage without any flowers. Additionally, the leaves could turn brown or yellow. They might also look bent and lifeless. Therefore, make sure you don’t over-fertilize.

Many people choose the rose of Sharon for their privacy fences or hedges due to the plant’s height as well as colorful flowers. It can add more life to your garden, which is always a plus. Creating a hedge with this plant is easy, and all you need to do is leave enough space between the plants. Rose of Sharon will fill it up in no time.

We have mentioned that most gardening enthusiasts plant rose of Sharon outside, but this bush can thrive in a pot as well. It will not grow to be super tall, and you will need to prune it occasionally. It will still look pretty in indoor settings.

Watering Rose of Sharon

Rose of Sharon prefers moist soil, especially during spring and summer. Water it frequently to increase the number of flowers. On the other hand, too much water can damage the plant. If you notice that the leaves are turning yellow, it doesn’t mean the plant needs more water. Instead, you have been overwatering it.

This shrub is drought tolerant and can survive a short period without water. The plant will not be harmed in any way. Return to your watering schedule, and the rose of Sharon will continue to grow, producing large and colorful flowers as usual.

Propagating Rose of Sharon

Rose of Sharon is propagated through cuttings. You can do so at any time of the year. But there are a few things you need to remember if you want to grow another bush in your yard. For instance, take green cuttings during summer and wooden cuttings in fall or winter. The wooden cuttings should be at least one year old. Aim for 4 to 6-inch cutting. All leaves except for the top ones should be removed.

If you are propagating the rose of Sharon in summer, you can take the fresh cutting and place it directly into the ground. The soil needs to be moist and fertilized. Keep watering the new plant frequently, and it should develop the root system in no time.

Generally, the safest way to propagate rose of Sharon is to place a fresh cutting into a pot. Use a rooting hormone on the bottom part of the stem and place the lower half into a pot. Water the cutting and cover it up with clear plastic.

The pot should be kept in shade or indirect sunlight. Remove the plastic after one week. Keep the soil moist but not too much. The root system will develop after one or two months. You can check by pulling the plant up. Also, if you see new leaves, the cutting is adapting and growing.
