Requirement for Pruning:

If you want your Globe Amaranth plants to produce more flowers and fruits, then you should prune them. As mentioned before, it blooms profusely. If you do not prune it, then it may block sunlight to other plants in your garden. As a result, your other plants may not grow well.

Pruning it will make it easier to harvest its fruits later. Pruning should be done after the plant has flowered and the fruit is developed. This ensures that the plant will bloom again and keep the shape of your plant.

Globe amaranth can be propagated in two ways: by planting the seeds directly into the soil, or by replanting the seedlings. The easiest way to propagate is by replanting the seedlings as soon as they are removed from the pot (after they have been successfully transplanted). 

If you replant the seedlings, they will have deeper roots and will be able to get more nutrients from the soil in a shorter amount of time.

Prepare it for Winters:

Plants that are going to be overwintered should be provided with a cold frame for adequate protection. The cold frame should be insulated with rotted-down compost and the entrance should be shaded to increase the temperature inside of it.

Water the plants abundantly during cold weather. Amaranths will survive a light frost but require moist soil to survive a heavy frost. If the soil is dry, the plants will just die.

Common Pests and Diseases:

Globe amaranth is very resistant to pests and diseases. Thrips (several species) are the most widespread pest of amaranths. Damage caused by thrips includes stunting, yellowing and bronzing of the leaves, and malformation. 

These plants also attract aphids, cabbage loopers, cabbage white butterflies, flea beetles, mites, silver leaf whiteflies, and tomato hornworms.

A pest control program is essential for the long-term survival of this plant. It is advisable to use a pesticide that is approved for use on amaranths. Regular and persistent inspections will prevent them from causing any major damage. 

Final Thoughts:

Globe amaranth is a drought-tolerant plant that will thrive in most soils. The plant is a hardy perennial that can be grown in almost any soil. 

The plant is also very easy to grow and is known to grow in a wide range of temperatures. It is best to grow it in soil that is rich in nutrients. So, if you are looking for a plant that you can easily maintain and is beautiful with a lot of uses, then you should grow this one.
