How to have a successful your tulip garden?
A garden without tulips is not a real Spring garden ! Tulips, because of their great diversity of colours and forms, look well in any type of garden.
For a good global effect, especially within the confines of a city garden, it is best to use one variety per patch. For the best effect, plant between 10 and 15 cms. in depth, according to their volume (around twice their height), 60 to 80 bulbs per sq. metre (depending ontheir size), leaving a distance of 8 to 10 cms. between each bulb.
Bulbs should be planted in October or November (no later than mid-December) because their development is conditionned by the the changing of temperature from a cold period to a period slightly warmer. This way they will benefit from the cold throughout Winter and will wake up with the first warmth of Spring.
By planting according to their flowering periods - late flowering bulbs planted deeply with earlier ones planted above them - your garden will be in flower from mid-March to mid-May.
Plant in a patch in full sunlight, in light, even poor, soil. If the soil contains a lot of clay, add a bit of sand to it or put a handful of sand in each planting hole.
