If you plant alstroemeria indoors, you can do so any time of the year as long as you place the plant in a temperate location.
If you live in an extremely hot climate, you may want to place mulch around your alstroemeria in the summer. If you live in a cold climate, you should place mulch around your alstroemeria in the winter.
Each flower has its own stalk, so you won’t harm the entire plant by pulling a few stalks. In order to encourage growth, regularly deadhead spent blossoms.
Expect the newly planted rhizomes to flourish within 10 weeks of planting. Thin and transplant the rhizomes every 2-3 years during the spring.
