Tulips bloom for three consecutive years, blooming as promised year after year
Since 1998, I have used 8 commercially available tulip bulbs and planted them for three consecutive years; they bloom every year, and they have already multiplied to forty or fifty bulbs. Books say the planting time for tulips is late October and early November. The main producing country, the Netherlands, is a high-latitude country with a cold climate, so tulips need to grow in a cold environment. Potted plants should be placed outdoors, not indoors or in a warm shed, otherwise they will not bloom (this is also the conclusion I drew from a comparative experiment). In winter, outdoors, it only grows roots and does not sprout, until early spring in February
