The wonderful life of bulbs

The latter part of Winter and early part of Spring are the times of year when numerous bulbs start to erupt into a flurry of colour in the garden and wider landscapes. There are many varieties of plants that originate from bulbs and tubers. These include the likes of tulips, daffodils, dahlias and lots more. Bulbs are in essence their own little energy centres and they provide the flower with everything they need and are the area to which the plant retreats and hibernates during the cold weather. Even those indoor plants that have the benefit of the warmth from the heating system. As long as you make sure that you have a Boiler Service Gloucester company such as hprservicesltd.com/gloucester-boilers/boiler-service-gloucester/ check the system each year you should have a smooth-running heating system.

Bulbs are underground stems that produce leaves, shoots and roots from within the layers that wrap around the internal core. It is these leaves that protect the delicate insides of the bulbs from the effects of the environment that it is in, including attack from insects and damp and mould from wet soil. Bulbs can struggle to survive in extremes of either end of the temperature spectrum, with hot dry weather being as damaging as cold icy temperatures. When the winter weather beings the bulbs send all energy and sugars down to the core of the bulb and this results in the top parts of the plant dying back. It is this process that allows the plant to come back year after year. During the winter season the bulb is effectively in a type pf suspended animation or hibernation. When the temperature of the soil starts to warm up the bulb core will start to send shots out above the soil.

There is a cycle to the yearly life of a bulb:

Winter – Dormancy: The plant is in hibernation and retains as all of its energy in the core of the bulb and this is in the form of sugars and starch that were sent back down to the core from the leaves and flower before they died back.

Spring – Releasing energy: The plant is very sensitive to the changes of temperature in the soil and it is this increase in temperature that signals to the core that it is time to release further roots to begin to obtain moisture and nutrients from the soil ready for the summer season.

Early Summer – Sprouting: Leaf buds appear around the core of the bulb and beginning to sprout above the soil. Photosynthesis can occur once the leaves reach above the ground level and the energy for further growth is created.

Summer – Flowering: After creating enough energy for the leaves and plant to grow flowers will appear and all the energy is directed to these in order to attract insects and other animals in order for the plant to be pollenated.

Late Summer – Hoarding energy: When the flowers start to wilt the plant begins to send all the energy it creates through photosynthesis back down to the core of the bulb ready for the winter period. The leaves above the ground start to die back.
