It is better for Gladiolus to have a flat ball and medium size.
The flat bulb indicates that it has degenerated or even aged, and is not suitable for planting; the bulb is too large, although it has more germination, but it consumes a lot of nutrients, and the flowering is not good.
The bulbs should be free of brown or black spots, mildew, rot and insect bites.
Because the bud eye is the place where the bulb germinates after planting, and the bottom of the bulb is the place where the root sprouts, the two parts cannot be damaged, otherwise it will affect the root and germination, and the plant cannot grow normally.
There are many kinds of gladiolus. When choosing, we should choose pure species and try not to choose hybrid ones, or we will not get the desired flower branches.
If you want a specific flower color, you can choose it according to the seed ball. For yellow or orange flowers, the bulb base will be yellow; for red or pink flowers, the bulb base will be pink; for white or light flowers, the bulb color will also be light.
