Alstroemeria


Question: Alstroemeria


Hi, I just bought an alstroemeria.
I inquired a bit around and they told me that, with harsh winters (I live in the North), the rhizomes freeze and it would be better to put them in a proper place ... my question is, can the rhizomes be extracted and stored as is done with the bulbs? thanks

Answer: Alstroemeria


Dear Jessica,
astrometries are perennial herbaceous plants, with a rhizomatous root; in essence they produce a sort of bread of thickened roots, which resemble those of dahlias a little; they can easily live in the garden, where, if the climate is mild, they tend to develop like evergreens, and the floral stems, by drying, serve as protection for the new shoots. In fact, however, if the winter climate is very rigid, it is convenient to repair them in some way, because they do not tolerate prolonged and intense frost. You can extract the rhizomes from the soil, slightly dry them, and then place them in a jute bag, sprinkled with sand or sawdust, and even before using fungicide; the bag should be stored in a dark and cool place, for example in the cellar; unfortunately you will have to periodically check that the plants do not develop mold or fungus, and that they do not tend to dry out too much.
If you grow them in pots, you can also simply move the whole pot into the cellar, after allowing it to dry for at least a couple of weeks; when spring comes, all you do is move the pot outside, and start watering again. Or you can mulch the soil with dry leaves or barks, so that the frost does not reach the rhizomes, or you can even cover the entire pot with non-woven fabric. In fact they are not plants that fear the cold absolutely, simply, long periods of freezing and high humidity can cause the rot of the rhizomes.
