Why plant flower bulbs?
Flower bulbs are easy to use, versatile, and instantly add ambiance to even the simplest garden. Whether you choose a colorful mix of tulips or subtle creamy daffodils, you can't go wrong with flower bulbs.
Advantages:
Long flowering period, from early spring to late autumn
Low maintenance
Suitable for garden, balcony and pot
Perfect for filling in bald spots
When should you plant flower bulbs?
The timing depends on the type of bulb you choose. We distinguish between spring-flowering and summer-flowering bulbs.
Spring-flowering bulbs (plant in autumn)
Such as: tulips, daffodils, crocuses, snowdrops, blue grape hyacinths
Plants from September to December
Flowering from February to May
Why in the fall?
The bulbs need cold to form roots. This way, they'll emerge naturally in spring and bloom early.
Tip: Plant before December, as long as the ground is not yet frozen.
Summer flowering bulbs (plant in spring)
Such as: dahlias, gladioli, callas, begonias, anemones
Plants from March to May
Flowering from June to October
Summer bulbs absolutely hate frost. Plant them only when the risk of night frost is minimal.
Tip: You can start dahlia tubers indoors in pots to encourage earlier flowering.
How do I plant flower bulbs? (Step-by-step plan)
Here is the simplest and most effective method for planting flower bulbs.
1. Choose the right place
Flower bulbs usually like:
well-drained soil
a sunny to partially shaded spot
enough space to grow
In pots?
Provide drainage at the bottom: hydro grains or shards of old pots.
2. Dig the planting hole (pay attention to the depth!)
A rule of thumb for all flower bulbs:
Planting depth = 2 to 3 × the height of the bulb
Examples:
Tulips: 10–15 cm
Crocuses: 5–8 cm
Daffodils: 10–20 cm
Dahlias (tubers): 5–10 cm
3. Place the balls with the point facing up
The point is where the stem emerges. Is the bulb not clearly visible?
Then just plant it: Mother Nature will find a way.
Planting distance
Small balls: 5 cm
Medium bulbs: 10 cm Large bulbs (such as tulips): 12–15 cm
4. Fill the hole and water
Cover the bulb with soil and water generously.
This helps with:
activating root growth
fixing the earth around the sphere
5. Mulching and finishing
A layer of mulch protects against:
frost
dehydration
weed growth
Perfect for autumn bulbs!

Frequently asked questions about planting flower bulbs
How deep should I plant flower bulbs?
2–3 times the bulb height. Simple and always good.
Do I need to feed flower bulbs?
Spring bulbs usually don't. Summer bulbs do like to grow.
