Big flowerbulb = Big flower?
The size of flower bulbs is an important factor in the quality and appearance of the flowers and plants that grow from them. So it is not surprising that there is a great demand for larger bulbs. But why is this so important and how is bulb size measured?
How is the size of flower bulbs measured?
The size of flower bulbs is measured in centimetres and refers to the circumference of the bulb. The larger the bulb, the more nutrients and energy it contains. The reason for this is that larger bulbs have more cup or storage leaves that can store nutrients and energy. This means that larger bulbs have a higher metabolism, resulting in bigger and stronger flowers and plants. When a bulb is planted, it uses this energy to form roots and grow. Over time, the plant forms leaves and eventually produces flowers. When a bulb has more nutrients, the plant can produce more leaves and flowers.
Official bulb size classification
There is an official classification for the sizes of flower bulbs. The largest size is called "Mammoth" or "Jumbo" and is usually 4,7 inch in diameter. The next size is "Size 1" with a size of 3,9-4,7 inch. Size 2 has a diameter of 3,1-3,5 inch and the smallest size is "size 3" with diameters of 1,5 to 2,7 inch.
For dahlia tubers, the classification refers to the weight of the tuber. Tuber sizes I and II are suitable for cultivation. Tuber size II has a weight of 50 to 100 grams. From 100 grams it is tuber size I. Again, the heavier the bulb, the more profusely the flower is likely to bloom.
Larger bulbs are hardier
In general, larger bulbs are more resistant to plant diseases and pests than smaller bulbs. This is because larger bulbs have more reserves to recover from a stressful situation such as a disease or pest invasion.
Larger onions often bloom longer
When you put a bulb in the ground, it uses up its energy to grow and develop. When the flower has faded, the plant starts to put its energy into producing seeds. When a bulb is bigger, it has more energy to produce seeds. This means that the plant can live longer, produce more flowers and reproduce better.
