Which plants have bulbs?
Plants with bulbs are exclusively from the monocot family. These include onions, crocuses, garlic, lilies, tulips, daffodils, hyacinths and certain groups of irises.
These bulb plants have one thing in common: they have a reserve organ that allows them to survive the period of rest of the vegetation, necessary for the flowering cycle of these plants. Depending on the plant, this organ has different names, the most common of which is the bulb.
The bulb is rounded in shape, and has a central bud enclosed in rather fleshy leaves.
When to plant your bulb?
Planting bulbs depends on the flowering period. This is done in the fall (crocuses, tulips, hyacinths, daffodils ...) for spring flowering bulbs and in spring (dahlias, begonias, lilies, canna, gladioli ...) for summer flowering bulbs.
Spring flowering bulbs should be planted in the fall. They then flower more or less early in the spring. Snowdrops, for example, bloom from January while tulips bloom rather between March and May.
Planted in spring, summer flowering bulbs bloom from June, and depending on weather conditions, until October. These are the dahlias that offer the longest flowering period for this type of plant.
Less known than spring or summer flowering bulbs, fall flowering bulbs plant in the spring or summer season. The fall flowering bulbs include cyclamen and even crocuses.
Where to plant your bulb?
Bulbs can be planted in the ground as well as in a planter or in a pot.
The bulbs are generally planted on light and warm soils with a sunny or semi-shaded exposure. Avoid stony soils because they are prone to flooding and too heavy.
Planting must be done in mixed soil (ordinary soil and bulb soil). Before planting, the soil must have been worked.
If you decide to plant your bulbs in a lawn, it is recommended to strip the grass and to dig the area before planting. To make it look more natural, do not hesitate to plant them randomly. Remember to mark the planted areas so as not to step on the bulbs.
How to plant a bulb?
Some bulbs remain in the ground throughout the year, while others must be removed because they fear frost. These bulbs should then be stored in a cool, dry place in the dark.
In general, you have to plant a bulb at a depth corresponding to two or three times its height. The bulbs are planted with the tip up. It is also necessary to separate 10 to 15 cm from each plantation.
For crocuses and snowdrops, the distance can be reduced. This can be facilitated by the use ofa bulb planter, which then removes a cone of earth to place the bulb there. Then you have to think about packing the soil well.
For autumn plantings, it is not necessary to water, because the weather conditions favorable to the rain will take care of it.
For planting your bulbs in pots, it is necessary to choose a suitable pot. For tulip bulbs or even hyacinths, which have large bulbs, opt for a fairly wide and deep pot. For crocus or muscaris bulbs, which are small bulbs, a smaller container will more than suffice.
