Alstroemeria plants, also known as Peruvian lilies, grow from tuberous rhizomes and benefit from deadheading. They are not deadheaded by simply removing the faded, colored portion of the flower and leaving the stem intact. In spring, an application of a balanced, slow-release fertilizer designed for flowering plants can help jumpstart growth. To keep potted Peruvian lilies in bloom, feed them monthly during the growing season using a balanced fertilizer.
After blooming, cut back the stalks that have finished flowering to encourage more blooms. Regular maintenance involves removing dead or over-fertilized flowers, as this can lead to abundant foliage at the expense of blooms. Deadhead spent flowers to encourage more blooming, and when the plant finishes blooming for the season, cut back the entire stem.
Alstroemeria aurantiaca (Peruvian Lily) is a robust, clump-forming perennial that can grow up to 48 inches (1.2 m) in height. Its main features include tuberous roots, sword-shaped leaves, and brightly colored flowers. Deadheading spent blooms is the best way to encourage more to appear, and it’s not recommended to use pruners to cut flowers from these plants.
You can continue deadheading throughout the flowering season, but it’s a good idea to leave dead vegetation of herbaceous perennials in place. It is easy to collect seeds from your own plants if you don’t deadhead them, but bear in mind that the resulting plants may differ from the parent.

Hello Sharon, thanks for your response, I have just had a look at your webpage and am very impressed, so sorry for your loss, I live in Perth West Australia although originally from Manchester UK ( 55 yrs ago ) and bought my plant about 2 yrs ago, had it in a large pot where it seemed to just exist ?. I transplanted it into the garden bed about 9 months ago and its gone off like a rocket, everybody is asking for a cutting or the name, This leads me back to square one where I was/am scouring the net on how to propagate these plants, it is our winter at the moment with spring just around the corner, so maybe a good time if it is possible, hope you don’t mind my asking, Bye for now, Norman
