Plants & Care

Care Inside

Spring-flowering bulbs, to be planted in autumn
Bulbs flowering in spring include tulips, crocuses, daffodils and hyacinths. On our packages you can find specific information about each variety as well as general tips for planting and caring

The best period for planting bulbs is from mid-September until mid-November. If bulbs are planted too early, the soil temperature may be too high, which may result in harmful mould. If  planted too late, the bulbs will not have enough time to develop roots before it starts freezing. Daffodils and snowdrops can be planted earlier, from the end of August.

Bulbs are not very choosy. The long-stemmed varieties should be planted in a more sheltered spot of the garden. Extremely wet spots must be avoided. Some types, such as crocuses, scillas, chionodoxa, snowdrops and eranthis grow well and flower longer in shadowy spots, e.g. under trees. However, the sunlight will make the colours come out more beautifully.

Before planting your bulbs, it is important to turn over the soil until about 20 cm deep. As a rule, the depth of the hole should be twice the diameter of the bulbs. However, we would advise to plant the bulbs somewhat deeper than that: 5 cm for tulip bulbs, 20 cm for daffodil bulbs, and 5-10 cm for smaller bulbs. Of course, bulbs should always be planted with their noses upwards. After having put the bulb in its hole, replace the soil and press it a little. Watering is only necessary when the soil is dry. The distance between the bulbs depends on the size of the bulbs and the quantity of leaves above ground. For smaller bulbs a distance of 5 cm is enough, tulips need 10-12 cm, and daffodils and hyacinths require a distance of 15 cm in between. These details can be found on our packages.

Frost protection
Hyacinths, Dutch irises and botanical narcissi like Tête-à-Tête may suffer some damage from moderate or heavy frost. This can be prevented by planting the bulbs rather deep. In addition, the planted bulbs can be covered with straw, as is done by professional growers.

Care during and after flowering
Generally, bulbs do not require a lot of attention. However, when using types or varieties which flower as late as May or June (late tulips, alliums, irises), it may be necessary to water more. After flowering, old flowers have to be removed, especially those of tulips and hyacinths. The plant will slowly die down.

Should bulbs be digged up or left in the ground after flowering?
It would be nice if once your bulbs were planted, they would flower forever. Unfortunately, this is not the case. Tulips, especially the botanical varieties, can flower two or three years in a row. Other types will degenerate sooner. As a general rule, bulbs are best digged up in summer. They should be cleaned (remove old skin, roots and small bulbs growing out of  the big bulb), stored in a well-ventilated place, and planted again in autumn.

There are also some types of bulbs which can be left in the ground, such as daffodils, narcissi and a great many smaller types, such as scillas, anemones, muscari and eranthis (winter aconites). After flowering in spring, these plants should be given some extra fertilization.

A number of types, such as snowdrops, will come back every year in ever larger groups. After a few years, they should be lifted, divided and replanted immediately in a larger spot.
