An amaryllis bulb must not disappear into obscurity if you want to enjoy a brilliant bloom. These instructions show how to skillfully pot a knight star. Benefit from our tips for the perfect substrate.

Planting time defines the beginning of the flowering period
A freshly potted amaryllis bulb produces the first buds after 6 to 8 weeks. The planting season begins in November so that the flower presents its picturesque splendor in time for Christmas. So that a Hippeastrum spreads its tropical flair during the Advent season, pot the tubers in October.
The optimal substrate - recipe suggestions for the best potting soil
With commercially available potting soil from discounters, they hardly meet the individual requirements of a subtropical amaryllis treasure. As a hobby gardener, you appreciate the value of your own mixture. These formulations have proven themselves in practice:
- A mix of 1 part potting soil and 1 part cactus soil is ideal, supplemented with lava granules
- A mixture of 2 parts low-peat vegetable soil, 1 part quartz sand (€15.85) and 1 part seramis is well suited
- A mixture of uniform soil and pricking soil in equal parts with 1 tablespoon of horn shavings (€32.93) and perlite (€37.51) breathing flakes is good
The lower the proportion of peat in the substrate, the better for water storage and for the environment anyway.
Step-by-step instructions
Choose a 12 or 14 cm tall, stable pot with a water drain in the bottom for the knight star. This is how you pot the flower bulbs in an exemplary manner:
- A 2 cm high drainage made of potsherds serves as drainage
- Spread a breathable and water-permeable fleece over it
- Fill the pot half to two-thirds full with the chosen substrate
Place the hippeastrum bulb in the middle of the ground with the tip pointing upwards. Only fill the container with substrate so that only half to a maximum of two thirds of the tuber are covered. Press the potting soil firmly and water thoroughly by pouring the water into the saucer. The next time it is only watered when the substrate has dried well.
tips
An amaryllis does not necessarily need soil for a breathtaking display of flowers on the wintry windowsill. Similar to a hyacinth, the onion reliably sprout in the glass. In addition, a knight star easily thrives in hydroponics.
