How to prune globe amaranth
Abstract: This article introduces some small experiences in plant cultivation, focusing on how to prune globe amaranth and detailed techniques for its maintenance. Let's find out more from the editor.
Globe amaranth belongs to the cruciferous family of perennial herbaceous plants, featuring an umbel inflorescence. It is famous for its bright colors, dense flower clusters, and long blooming period, making it an excellent plant for flower arrangements and also a great choice for potted plants.
1. Light pruning during the flowering period from March to April
Generally, globe amaranth cultivated indoors can bloom in spring if properly cared for during winter. After blooming, it is necessary to do some light pruning. It is recommended to remove the number of flower buds to control the blooming period and nutrient consumption, and to promptly remove the flower stems after blooming.
And promptly supplement fertilizer after blooming, such as during the spring flowering period and after flowering, by applying decomposed cake fertilizer (following the principle of applying thin fertilizer frequently) usually every two weeks. To promote the flowering period in June, you can appropriately increase the use of phosphorus and potassium fertilizers, such as 0.1% potassium dihydrogen phosphate, every half a month to promote bud differentiation and flower bud growth. Meanwhile, proper pinching can promote the growth of more branches.
2. Heavy pruning after flowering in June
Globe amaranth tends to grow poorly due to the hot weather in summer, so heavy pruning is usually done after flowering in June. Old branches, diseased branches, overly dense branches, and flower stems that have bloomed should all be pruned heavily.
It is recommended to place the plant in a cool and well-ventilated area immediately after pruning to spend the summer. Pay attention to replenishing the nutritional consumption during the flowering period, and fertilize as you would after spring flowering. Remember to prune and fertilize in summer to ensure a more abundant bloom in autumn.
The above information on how to prune globe amaranth and detailed maintenance techniques offers some useful knowledge. I hope this article can provide you with some help!
