Planting & Care
Growing globe amaranth is not difficult at all. Start seeds indoors six weeks before the last frost. They will germinate faster if you soak them in water prior to planting. If you wish to sow them outdoors, wait until the soil has warmed and there is no chance of frost.
Sunlight: Although the plants tolerate partial shade, full sun makes for more vibrant blossoms.
Soil: well-drained soil with a pH range of about 5.8 to 6.2
Water: Water the gomphrena just enough to keep its root zone saturated. Add water when the topsoil is dry to the touch. Although this plant tolerates the warm weather of the Bay Area well, it flourishes when kept on a regular watering schedule.
Fertilizer: Fertilize the plant with a balanced, slow-release fertilizer with an N-P-K ratio such as 14-14-14 at planting. Add a water-soluble fertilizer according to the instructions on the label once every few weeks.
- Once established, Gomphrena is actually maintenance-free.
- But if you want a healthy, deeply-coloured full plant, it s best to give your Gomphrena plant some extra pampering.
- Pruning: Pinch off the branches while it is young to promote bushier exterior.
- Also, pinch off wilted blooms.
- This will not only keep your plants neat and lovely but also prevent Gomphrena from seeding too early.
- The proper way to deadhead is by pinching the faded bloom with your fingernail, including the attached stem down to the succeeding bloom or leaf.
