Updated: April 14, 2022

Celosia is a beautiful flowering plant that belongs to the amaranth family. It is also known as cockscomb due to its unique shape that resembles a rooster’s comb. Celosia plants are easy to grow and maintain, making them an excellent choice for gardeners who want to add some colors and vibrancy to their gardens. One of the essential factors to consider before planting celosia is its growth rate.

Factors Affecting Celosia Growth

Several factors affect the growth rate of celosia plants. These include:


Celosia plants thrive in warm temperatures ranging between 60-85°F (15-29°C). High temperatures above 90°F (32°C) can cause the plant’s growth rate to slow down.


Celosia plants require plenty of sunlight to grow correctly. They need at least six hours of direct sunlight daily to thrive.


The type of soil used also affects the growth rate of celosia plants. The soil should be well-draining, rich in nutrients, and slightly acidic with a pH of 6.0-7.5.


Overwatering or underwatering celosia plants can affect their growth rate. They require regular watering to keep the soil moist but not waterlogged.

How Fast Does Celosia Plant Grow?

Celosia plants are fast-growing and can reach up to 1-2 feet tall within six weeks under ideal growing conditions. They start producing blooms within four weeks of planting, and the flowers can last for up to eight weeks before wilting.

It’s essential to note that celosia growth rate varies depending on the cultivar, environmental conditions, and care techniques.

How To Encourage Faster Celosia Growth

If you want your celosia plants to grow faster, you can implement the following techniques:


Fertilizing celosia plants with a balanced fertilizer once every two weeks can stimulate faster growth and blooming.


Trimming off spent blooms regularly encourages the plant to produce more flowers, leading to faster growth.


Mulching the soil around the celosia plants helps to retain moisture, suppress weeds, and regulate soil temperature, leading to faster growth.
