Planting instructions

Flower bulbs are perhaps the easiest products to plant in your garden because they already contain all the nutrients they need to flower. You only need to dig a hole, plant the bulb and close up the hole again. An advertising campaign was even invented for this called Dig, Drop, Done.

Just three words that tell you exactly what you need to do with your bulbs: dig a hole, drop in the bulb, and you’re done!

But there are many other tips you can use to beautify your garden further.

Flowering times and planting times

Plant spring bulbs in fall and summer bulbs in spring. Are you still following? To prevent confusion, we have divided our selection into summer blooms and spring blooms.

In the summer blooms range, you’ll find dahlias, gladioli and perennials, among other varieties, while in the spring blooms selection, you’ll find tulips, hyacinths, daffodils, alliums and so forth. In the spring blooms selection, we distinguish between early, middle and late-flowering plants. We tell you when each product in our catalog is meant to flower, so you can plan your purchases to make the most of their flowering times.

Spring bloomers can be planted from mid October (which is when we deliver your order), until the frosts begin. All spring bloomers need a period of cold in order to blossom in spring.

Summer bloomers can be planted from April until mid June, when there is no longer frost in the ground.

Where do I plant my bulbs?

Flower bulbs are available in many different heights, making them suitable to plant virtually anywhere in the garden. In our catalog, we have divided the bulbs into different height categories, which can be found in our advanced search menu. Select the height that you’re after then click search. You will see a selection of bulbs that meet your requirements. There are five height categories, each of which you can use to brighten up specific spots in your garden.

  • 2-10 inches is suitable for: pots, the front of your garden bed and as a carpet around the base of a tree.
  • 10-20 inches is suitable for: pots and the middle of your garden bed behind flower bulbs of 2-10 inches.
  • 20-40 inches is suitable for: a spot at the back of your garden bed, or planted in a large group in front of a shrub or hedge. Make sure you protect these bulbous plants from the wind by planting them in a sheltered spot.
  • 40-70 inches is suitable for: planting in a small group between shorter bulbous plants or in a small group between your perennials. Make sure you protect these bulbous plants from the wind by planting them in a sheltered spot.
  • 70 inches and taller: see 40-70 inches.

Please note: in every height category you will find products with different qualities to those stated above.

How do I plant my bulbs?

Try not to plant your bulbs in a straight line. Instead, experiment with round patterns and curves or plant them diagonal to one another to create a triangular shape. This will have a fuller and more natural effect.

Where will my bulbs grow best?

Flower bulbs will grow anywhere in your garden, as long as they get just a little bit of sun each day. The height and flowering time of the bulb depends on the amount of sun that reaches it. In spots that get a lot of sun, the warmth will cause your bulbs to flower a little earlier and grow a little higher than if they were in the shade a lot. A lot of sunlight will also cause the flowers to be a little lighter in color. But again, your bulbs will grow anywhere, so don't let any conditions put you off. 

Which soil is best?

Bulbs are not particularly fussy about what type of soil they grow in, as long as it has fairly good drainage.

If you want to plant your bulbs in pots  use regularcompost from a garden centre, possibly mixed with a little soil from the garden.

Will bulbs grow in my climate?

There is a flower bulb to suit nearly every climate. Use the United States zone map to see which zone you live in. In the advanced search menu you can select bulbs that grow and flower in your zone. The best zones for each bulb are also labeled on every item in our catalog.

Note that the zones stated are the zones for which the bulb is most suitable. This doesn’t mean that they won’t flower in other zones.


If you have planted bulbs that are suitable for naturalizing, there are a few things you can do to help ensure they flower just as beautifully the following year.

Once the flowers have finished flowering, simply cut them off. This will cause the plant to invest its energy in growing the bulb rather than feeding the flower. At this point, you can add a little fertilizer to the ground, giving it enough nutrients to feed the bulb, preparing it to flower the next year. After a while the leaves will die off. As soon as they are brown and dried out, you can remove them too.

Tip: Plant summer blooms between the bulbs that have finished flowering. This will give your garden color again.

Which color should I choose?

This is tough to answer because everyone's tastes differ. But we can certainly give you some tips.

Choose a color that contrasts with the color in the background (for example a red tulip in front of a green hedge). This will make your bulbs really stand out. 

You can also apply the colors and ambience that you have in your house in your garden to create a connection between your indoor and outdoor spaces. Using thedvanced search menu, you can select the color that you like and choose your flower bulbs that way.
