After the leaves and flowers of the plant have fallen, we can think of collecting the bulbs to be able to replant them the following season.
First we must wet the earth to facilitate the excavation operations and thus avoid damaging them.
Then we will clean them and let them dry, only at this point we can proceed to the steps for conservation.
First of all we will have to sprinkle them with fungicides and pesticides to prevent them from being eaten by insects or attacked by molds (ask for these products from your trusted nurseryman).
At this point we can put them in boxes filled with sawdust or put them in suspended nylon stockings
