Sowing Instructions

Cleome (Cleome hassleriana) is a beautiful flowering plant that can add a burst of color and vibrancy to any garden. If you’re looking to start growing cleome, then sowing seeds is the best way to get started.

Firstly, it’s important to choose a spot in your garden that gets plenty of sunlight and has well-draining soil. Cleome requires full sun to thrive and prefers slightly acidic, well-drained soil rich in organic matter.

To sow cleome seeds, start by preparing the soil. Remove any weeds or debris and loosen the topsoil with a hoe or garden fork. Then, create furrows or shallow trenches in the soil using a seed planter or your hand. Make sure the furrows are spaced at least six inches apart to allow for proper growth and development of each plant.

Next, sprinkle the cleome seeds into the furrows, being careful not to overcrowd the seeds. Cover the seeds with a thin layer of soil, and then water the area thoroughly, making sure the soil remains moist but not waterlogged.

As the cleome plants begin to grow, thin them out so that they’re spaced six to eight inches apart. This will make sure each plant has enough room to grow and develop properly. When the plants reach a height of around twelve inches, pinch the growing tips to encourage branching and a fuller, bushier plant.

Light Requirements

When it comes to growing healthy Cleome, proper lighting is crucial. These vibrant plants require full sun or at least 6 hours of direct sunlight each day. If you’re growing indoors, providing this type of lighting can be a challenge, but it’s not impossible.

One way to meet the lighting requirements is to position the plants close to a south-facing window. This position will ensure they receive maximum exposure to the sun’s rays.

What You Need To Know About Fertilizing Cleome (Cleome hassleriana)

When it comes to fertilizing Cleome (Cleome hassleriana) plants, there are a few key things to keep in mind in order to ensure they grow up healthy and strong.

First and foremost, fertilizing should only be done after the plant has developed a few true leaves and has been growing for a few weeks. This will give the plant time to establish its root system and become a bit heartier before being introduced to additional nutrients.

It’s important not to over-fertilize Cleome plants, as this can actually harm their growth and development. As a general rule, it’s best to fertilize once every four to six weeks during the growing season and avoid fertilizing altogether during the plant’s dormancy period.

By following these guidelines and giving your Cleome plants the right balance of nutrients, you’ll be setting them up for a healthy and beautiful growing season that’s sure to impress.

My Favorite Fertilizers For Cleome (Cleome hassleriana)

When it comes to ensuring the health of your Cleome plant, selecting the right fertilizer can make all the difference. Here are some top options to consider:

1. All-Purpose Fertilizer: If you’re looking for a quick and easy option, an all-purpose fertilizer may be the way to go.
