Naturalizing bulbs

What are naturalizing bulbs?

Naturalising bulbs are perennial flower bulbs that are resistant to viruses. They are usually wild bulbs that, just like in nature, grow wild without any maintenance. They have the ability to multiply and even spread over time, creating a natural and colourful mix of flowers.

Which flower bulbs naturalize

Flower bulbs that naturalize are mainly the poisonous flower bulbs that feed on their own poisons, such as daffodils or flower bulbs from the hyacinth family such as bluebells. Non-poisonous flower bulbs naturalize best where there is shade during the warm summer months. We mention the ornamental onions that can be planted well between other crops, which provide a cool base.

When do naturalising bulbs bloom?

Most naturalising bulbs grow at low temperatures. These are the low species that flower from early spring. The later summer flowering naturalising bulbs are usually a bit higher, such as the alliums.

Unfortunately, not all flower bulbs are grown organically, which means that there are no autumn flowering naturalisation bulbs available, such as the autumn crocus. We hope that more growers will soon switch to organic.

Sustainable flower bulbs

Organic naturalisation bulbs are extra sustainable, because of their long lifespan and ability to multiply. This means that annual purchase of flower bulbs is not necessary, which saves a lot of work and money.

Where do you plant naturalizing bulbs?

In general, most naturalizing bulbs thrive in well-drained soil in a sunny to lightly shaded location during flowering and in the summer during the dormant phase in the shade, for example under deciduous trees. Each naturalizing bulb prefers its own location. Check the planting instructions on the product pages for the right choice.

Naturalizing bulbs under trees

When planting naturalising bulbs it is important to consider the specific requirements of each flower bulb, such as the flowering period, the location and the depth of the planting. Large flower bulbs may be less suitable for planting under deciduous trees, because the root system of the tree may get in the way when digging a large hole.

Naturalizing bulbs in the grass

Naturalising bulbs have the advantage that they can also be planted in the grass. Be careful if you want to plant late flowering naturalising bulbs, you also choose the higher types such as the drumsticks, which can flower in July between the unmown grass.

Caring for naturalising bulbs

Naturalising bulbs require little care. When the bulbs start to root above ground after a few years, you can replant the bulbs at a planting depth that is 2 to 3 times as deep as the bulb itself. The Florist advises naturalising bulbs to be provided with organic food every year, so that the young brood bulbs also become ready to flower more quickly.

Naturalising bulbs in wet areas in the garden

Some naturalising bulbs such as snowdrops or summer snowflakes prefer a location where it is not too dry. These can often be planted in clay soil or other wet places in the garden.

Buy organic rewilding packages

Using organic naturalising bulbs from reliable nurseries ensures you are making an environmentally friendly choice for your garden.

  • Organic spring bulbs

    Spring-flowering bulbs and tubers are popular plants that produce beautiful flowers from early spring through summer. Because of their early bloom, they combine well with perennials when they still need to establish themselves.

    Tulips are probably the most well-known spring flowers. They come in many different colors, shapes, and sizes. Daffodils are known for their cheerful yellow flowers, but they also come in other colors like white and orange. Crocuses are small bulbous plants with striking flowers in shades of purple, yellow, and white. They are often the first flowers to appear in spring. Hyacinths have fragrant flowers in various colors, such as pink, purple, blue, and white. They are often planted in borders, flower beds, or pots.

    Benefits of organic spring bulbs

    When you choose organic flower bulbs that bloom in spring, you can be sure that no chemicals or pesticides will end up in your garden. These pesticides are harmful to bees and prevent them from finding their nests. As a result, more and more bee species have been added to the red list in recent years. Together, we can do something about this!

    Flower bulbs for wild bees

    Did you know that wild bees lay eggs in their nests, which then hatch in early spring? These newborn insect helpers immediately search for food in the surrounding area. There are also insects that have hibernated and are desperately looking for a hearty breakfast: the blooming flowers where nectar and pollen can be found! Just after winter, there's little greenery or food for these insects. Planting early-blooming flower bulbs ensures there's food available, and the insects can gain strength for the coming summer.

    Organic growers

    The organic growers we work with cultivate not only the most beautiful but also the strongest products. They cultivate varieties and species of flowers and plants that experience has shown to be virus-resistant, so they don't need to use chemicals and pesticides. Organic growers seek natural remedies and solutions against diseases and/or pests. All our flower bulbs are certified organic; both the Florist and the growers are SKAL-certified.

    When do you plant spring bulbs?

    Spring-flowering bulbs can be planted from autumn until January. Bulbs that need to be dug up in the summer after flowering should be dug up starting in late July and stored until the next planting season in autumn.

    What to do after flowering

    When spring bloomers have finished blooming, cut off the wilted flowers at the top of the stem. Let the rest of the plant die back naturally so it can still receive maximum energy from the sun.

    How do you store spring bulbs?

    If you've purchased flower bulbs from us and had them delivered to your home and would like to leave them for a while, we recommend opening the box and storing it in a ventilated, cool place until you're ready to plant them.

    Store flower bulbs you dig up after flowering in a warm place, such as a shed. To prevent mice from eating the bulbs during this period, you can also hang them in a bag or pantyhose.

  • Where is the best place to plant spring bulbs?

    Spring-flowering bulbs are flowers that bloom in the spring, between January and July. There are many different types of spring-flowering bulbs, suitable for different types of gardens and soil. For example, some bulb plants enjoy catching a glimpse of the sun during flowering, but prefer to be covered by a tree during their dormant period in summer.

    Spring bloomers in the sun

    Many spring bloomers need plenty of sun to bloom and grow well for the following year. These flowers thrive in full sun:

    Conclusion

    There are many different types of spring bloomers suitable for different types of gardens and soil. Whether a spring bloomer can grow in sun or shade depends on the specific variety. Some prefer dry soil, while others prefer wet feet. So, there's a suitable spring bloomer for every garden.
