At the stage of collecting planting material, a serious mistake can be made, due to which the gladioli will not bloom lushly next year.
The nuance lies in the timing when you can dig up flower bulbs.
There is one rule that will help you accurately determine specific days.
The rule is universal for all varieties of gladioli. The bulbs are dug up 30-40 days after removing the flower stalk.
The rule works for any climate. However, the bulbs are dug up at a temperature of no less than +8 …+10 °C.
If you rush in this case, the quality of the planting material will suffer. If you dig up the bulbs too early, they may die.
Therefore, there will be nothing to plant next spring. The same result if you wait for the cold weather.
