Lesson 6
As cut flowers — and propagating offsets
Growing image…
Cut when the lowest bud on the stem is just opening — the rest will open in the vase over a week. Take stems with at least 2/3 of the foliage left on the plant; if you cut more, you starve the bulb.
Vase life: 10–14 days, the longest of any common cut flower. Remove anthers as buds open to avoid staining.
Propagating: when you lift a 3-year-old pot, you'll find pea-sized offset bulbs around the parent. Pot these into 1 L pots of gritty compost; they will reach flowering size in 2–3 years. The cheapest way to multiply named varieties.
What to add to vase water (per 1 litre)
- 1 teaspoon of sugar — feeds the flower in place of the stem it lost.
- 1 teaspoon of lemon juice OR clear (white) vinegar — lowers the pH so water moves up the stem more easily.
- 2–3 drops of household bleach OR a clean copper coin — stops the bacteria that block the cut stem (the real reason vases go cloudy and flowers droop early).
- Change the water every 2 days and recut 1 cm off the stem each time. That single habit beats any other 'trick' for vase life.
- Florist sachets (Chrysal, Floralife) are this same recipe pre-mixed — convenient, not magic. Either is fine.
- Avoid: aspirin, copper pennies post-1992 (not real copper), and full-fat lemonade — the sugar load encourages slime.
Lilies in arrangements
- Pick stems when the lowest bud cracks; rest opens in the vase.
- Cut anthers off as each flower opens — or wear an apron forever.
- Recut stems underwater and condition for 2 hours in cold deep water.
- Stand a single stem in a tall vase — lilies are architectural alone.
- Lily pollen on fabric: lift off with sticky tape; never rub or wash first.
