Preparation
To ensure that a plant and its flowers develop optimally, the soil could be fed in advance. We recommend Bio-Kultura for this.
Planting time autumn:
Plant the spring flowering bulbs in the ground in the fall until the end of December. Do not water this. They get this automatically during the winter from the rain. Plant the flowerbulbs 2 to 3 times as deep as the bulb itself. If a flower bulb is 5 centimeters in size, it is planted 10 to 15 centimeters deep in the ground. The flowerbulbs planted in the fall bloom in early spring.
Naturalizing bulbs can remain in the ground and return annually.
The well-known fragrant hyacinths and tulips are best removed from the ground after flowering, when all the leaves have withered. These are kept in a warm place in the summer, for example in the shed, and then replanted in the ground in the fall.
Spring planting time:
Plant the summer-flowering flowerbulbs and tubers in the ground in the spring. Plant the flower bulbs and round tubers 2 to 3 times as deep as the bulb or tuber itself. For rhizomes or dahlia tubers, spread the tubers over the soil and cover them with about 2 to 5 centimeters of soil. ( Peonies are planted less deeply in the ground. It is important that the new red/pink shoots protrude just above the ground.) Provide sufficient water after planting.
There are summer-flowering flowerbulbs that can remain in the ground during the winter, such as the liatris, and there are species that need to be removed from the ground before the winter. Store non-hardy flowerbulbs in a cool, dry and frost-free place and replant them in the ground in the spring.
Planting time summer:
Some fall-blooming bulbs are planted in summer or early fall for fall bloom. Consider, for example, the saffron crocus.
