Сoral Bells height

The table shows the height does not include the peduncle. With the peduncle, Heuchera can reach 20-22 inches and even more.

Let’s talk about conditions in more detail, and I’ll tell you what you can do to increase or limit the height and width.

How big the Heuchera will depend on the planting site

The landing location affects the height and width of the coral bels. As you know, some varieties can be planted in full sun, but in such conditions, the plant will not grow to the maximum size, even if the plant is often watered.

In full shade, a bush of Heuchera will have fewer leaves and branches than half a shadow so that it will be lower. However, the plant will grow in diameter and become flat.

If the plant receives enough sunlight and is partially shaded, it can quickly become as high as possible. The half-shade is most comfortable for Coral Bells.

The type of soil also affects the size of the plant

In dry sandy soil, this plant will grow quite slowly and sluggishly. So if your purpose is a compact plant size, plant it in this type of soil.

It is best for the vigorous growth of heuchera moist soil with many nutrients. In such land, this plant may exceed 18 inches in height.

The larger the variety, the bigger it grows

The height of the bush depends on the size of the cultivar. The dwarf variety will never grow tall. Large types under favorable conditions can become quite high.

Other factors

  • With age, Coral Bells grows taller Every year heuchera stem grows higher, it can twist or grow upwards. If you do not transplant or prune it for a few years, this plant may exceed the height considered normal.
  • Sufficient moisture Good watering can provide the plant with enough moisture in the soil. Such conditions are ideal because the Heuchera grows in rocky terrain where the earth is moist.
  • The amount of fertilizer Without sufficient fertilizer, Coral Bells will grow well but will not reach significant sizes. With enough, and most importantly, constant nutrition, these plants will please you not only the dimensions but also the bright colors of the leaves.

What can be done to make a plant grow bigger or smaller?

Let’s talk about making Coral Bells taller or lowering his height. I’ll tell you what techniques I will use to do this, and then answer some of the most common questions.

First of all, to make the bush taller plant it close to other plants; as a result, they will compete with each other and will become thicker and taller. Accordingly, to reduce the height of the plant, place it at a distance from other plants; as a result, it will increase in diameter more than in height.

The next thing you can do to increase the height is not to prune the plant for several years and not to transplant it. Conversely, if you need low heucheras, trim the stem every two to three years and replant the bush to a new location. This will slow its growth and reduce its height.

If your goal is to get high Coral Bels, then you can choose ampel varieties of this plant. Next, you need to create a support or a ladder on which the plant will be pulled up; from time to time, it should be tied. Ampel cultivars include:

  • Copper Cascade
  • Plum Cascade
  • Sugar and Spice
  • Pink Skyrocket
  • Crimson Cascade
  • Redstone Falls
  • Yellowstone Falls

All these methods, together with proper watering, fertilizers, moist soil, and sufficient sunshine, will allow you to reach the maximum height of your heucheras. If you need to reduce the size of your plants, you should do the exact opposite.

How tall do Coral bells get in full shade?

It is difficult to say precisely how much Heuchera will vary depending on solar exposure. I see that in my garden, those heucheras that grow in full shade are more creeping on the ground as if the bush is falling apart. The height will be about a few inches less than that growing in partial sun.

How wide do coral bells get in full sun?

In full sun, this plant will be a little more compact than in partial shade. The sun will have a more substantial effect on heucheras, and they will expand more slowly. It all depends on the varietal characteristics; the width will be less than approximate by 10% compared to those growing in a more suitable place.

How big do heucheras grow on sandy soil?

If you water them regularly and fertilize, they will be the same size as in wet soil. If you plant a heuchera in the sandy soil and do not water it, it may die. In such land, it will be slightly smaller. Medium-sized varieties in sandy soil will grow up to 13 inches tall and 22 inches wide.
