Steps to undertake after lilies flower
1. Deadheading
After the peak of the bloom, spent flowers need to be eliminated immediately. If there are fresh lily blooms or buds, one can cut them and use them for decorative purposes. The spent flowers should be removed by hand or cut by shears as this prevents the plant from wasting resources to produce seeds. This is especially if the buds available are to be utilised the next season.

Deadheading lilies also assists in clearing the plant’s appearance because dead flowers and buds are not aesthetically appealing. Be careful to clear away only the spent flowers as removing the leaves causes the plants to produce less energy.

Pruning is essential for any plant’s healthy growth. Lilies need pruning after flowering to make room for new growth in the coming season. Pruning lilies prematurely is a disadvantage as it may cause the blooms and growth to diminish significantly. It is commendable to prune the lilies around late fall when the leaves are brown and falling off.
While pruning, use lightweight shears with sharp blades to administer clean cuts and also make sure the shears are disinfected to prevent plant infections. You can make your disinfectant by using water and vinegar in the ratio of 2:1 respectively.

3. Cutting lilies back
Eventually, lily stalks will turn yellow or brown but they should not be cut back until after the first frost. This is because the yellowing stalks still play a part in providing the energy required for the next flowering season. Lilies are usually cut back in autumn and spring when the plants have died back completely, and the leaves and stems no longer serve a purpose.
While cutting back, you need to mark where the stalks are to know where the lily buds are. This is to avoid damaging them unexpectedly by digging.
4. Mulching is crucial

Once you cut back the lilies, it is essential to apply mulch as it helps the soil stay moist during winter. Mulch also acts as insulation from the cold thus preventing ground freezing. The mulch is to protect the roots until after the first frost in spring. The mulch will be eliminated once new shoots emerge and there is a need for space.
