Excavate Montbretia in autumn
In areas with a harsh climate, the stolons, the underground storage organs of the Montbretie, must be carefully excavated. Proceed as follows:
- Pierce the earth with a digging fork at a sufficient distance from the tubers.
- Lift the clod carefully so as not to damage the stolons.
- Select the tubers with as much garden soil as possible.
- Unlike many onion plants, it is essential to leave the soil on the rhizomes so that they do not dry out.
- Check montbretia and substrate for pest infestation and store only flawless tubers.

Store the tubers in a dark, cool and frost-free place. A basement room or garage is well suited.
Provide winter protection in mild regions
If, on the other hand, you live in an area where it does not get colder than minus ten degrees in winter, you can overwinter the Montbreti outdoors. In this case, do not cut back the montbretia, because the above-ground parts of the plant serve as natural protection against the cold.
Apply a generous layer of leaves or mulch (€ 213.00 at Amazon *) over the tubers and leaves, which you also weigh down with brushwood to prevent the warming blanket from blowing away. Since the plant material is permeable to air, oxygen can pass through it unhindered and putrefaction is effectively prevented.
Tips
If you want to overwinter the Montbretians indoors, the use of plant containers is recommended. These not only protect the Montbretians from vole bites, but can also be removed from the ground as a whole in autumn. The potting soil may remain in the baskets as protection for the rhizomes.
