The 10 most-asked questions about bulbs
If the choice of bulbs has been adapted to the local conditions, no fertiliser is necessary, in principle. However, if you want to be absolutely sure that they bloom next season, some fertiliser (preferable organic) could be given, immediately after bloom time.
No, never. Through these leaves the bulb collects new, essential nutrients for the next season.
Spring bulbs are planted in fall, between the end of September and mid-November (for the Northern Hemisphere). Summer bulbs are planted late in spring, between the end of April and the end of May. The ‘Catalog’ section on TulipWorld.com can divide bulbs by their flowering season to make this selection easier.
Yes, most bulbs are doing very well in pots provided there is good drainage and the containers are large enough. They should be at least 10 inches wide and 10 inches high. Plant about twice as many bulbs in a pot as is recommended.
This depends on the intended effect and the species used. For a natural looking result you need 15-20 tulips, 20-30 daffodils, 75 crocuses and 50 Anemone blanda. If you look for color effect: 60-80 tulips, 60-100 daffodils, 150 crocuses and 150 Anemone blanda. TulipWorld.com feels to make an impact there are minimum numbers that should be planted and that number is listed with each bulb. If you naturalize, divide by two! Potting the bulbs, multiply by two.
Yes, for example: Chionodoxa, Puschkinia, Erythronium, Fritillaria meleagris, Hyacinthoides, Arum, Allium ursinum. Select shade conditions under the TulipWorld.com ‘Bulb Finder’ wizard for a full selection of what is available.
You plant bulbs on a depth of 2 to 3 times the height of the bulb. This is done to prevent drying out and freezing.
It is important that bulbs grow roots as soon as possible to be able to stand frost and cold. When it has not rained in the first week after planting, the bulbs should be watered.
For planting in lawns you need bulbs that bloom early in spring like Crocus, Scilla, Puschkinia, Galanthus, Erythronium, Anemone and Chionodoxa. After blooming they need time to let their leaves die off naturally. Only then can the lawn be mowed again.
Allium flavum, Allium ursinum, Chionodoxa (all species), Corydalis (all species), Crocus tommasinianus, Hyacinthoides non-scripta, Scilla (all species). All these increase easily as well. There is a “naturalizing icon” on each bulb page to let you know which ones are better adapted at this.
