When planting flower bulbs, not only the width of the pot should be used, but also its depth. Then several layers of onions can be placed. Optimal combination of varieties ensures good growth everywhere.
Flower bulbs with different planting depths can be combined well
Suitable flower bulb varieties
Spring bloomers are ideal for this project. They are diverse, sprout in different sizes and mostly grow tall without taking up much space. Therefore, the bulbs can be planted in large numbers next to each other or one below the other.
The best known and most popular representatives are certainly the colorful tulips, the wonderfully fragrant hyacinths and the sunny daffodils. But there is much more. Choose different
Flower bulb varieties that differ in bulb size.
substrate
If you plant flower bulbs in pots, the substrate must be permeable because wet flower bulbs rot quickly. Therefore, normal potting soil should be mixed with sand. You will still need drainage material such as gravel as well as fleece separating it from the overlying soil.
pot
Planting flower bulbs in multiple layers is also known as the lasagna method. For this, the pot must have the following properties:
- enough volume to accommodate all the onions
- its depth should be enough for several layers of onions
- have enough drainage holes for water to drain away
- consist of frost-free material (when wintering outdoors)
planting time
Plant the flower bulbs from around mid-September. Then they have the opportunity to take root well in autumn. However, if the weather is still very mild, you should wait a little longer.
manual
- First fill in a drainage layer and lay a piece of fleece over it.
- Spread a layer of substrate several centimeters high on top.
- Place the largest flower bulbs on top so that they are evenly distributed.
- Put a thin layer of substrate on top.
- Then layer the largest of the remaining onions.
- Cover them with some substrate as well.
- Continue layer by layer until all bulbs are planted.
- Finally, there is a layer of substrate on top. It should be twice as tall as the last bulbs planted.
- Water the onions well.
location in winter
The planted spring flowering bulbs are hardy but sensitive to frost in the pot. Place the pot in a cool basement for overwintering until it is time to sprout. A sheltered place on the balcony is also an option. However, the pot must be protected with fleece and the substrate covered with brushwood.
tips
Alternatively, you can bury planted pots in the garden and dig them up again in spring.
