Did You Know?
1. The growth of lilies is influenced by their bulb’s age. Younger bulbs tend to produce smaller and fewer flowers, while older bulbs are more likely to produce larger and more abundant blooms.
2. Lilies have been cultivated for over 3,000 years and are thought to be one of the oldest cultivated ornamental plants.
3. Some species of lilies display a phenomenon known as “gravitropism,” where the stems bend and grow towards the light, giving the flowers a unique angle.
4. The growth pattern of lilies is categorized as “monopodial,” meaning they grow from a single central stem, as opposed to “sympodial” growth, where plants have multiple shoots.
5. Lilies are sensitive to certain odors, and some species can even be damaged or have their growth stunted if exposed to scents like those from apple, chrysanthemum, or citrus blossoms.
Different Types of Lilies
Lilies, belonging to the genus Lilium, are exquisite flowering plants that grow from bulbs. However, it is important to note that not all plants commonly referred to as lilies are true lilies. Daylilies, peace lilies, and canna lilies, for example, do not fall under the Lilium genus. True lilies are categorized into different species, including Orientals, Asiatics, Orienpets, and Species types.
Lilies are renowned for their elegant, six plain or strikingly marked petals that come in various colors. The Asiatic lilies are the earliest to bloom, usually in May or June, and they are also the easiest to grow. Their vibrant blooms make them a popular choice amongst gardeners. Oriental lilies, on the other hand, make an impression with their intoxicating fragrance and can reach heights of up to 4 feet. These lilies bloom in mid- to late summer, creating a mesmerizing display of color and fragrance.

Other types of lilies that deserve mention include the Tiger lilies, Turk’s cap lilies, Orienpet lilies, and LA lilies. Each of these varieties possesses unique characteristics that add to the diverse allure of the lily family.
Care Tips for Growing Lilies
Lilies are perennials that require minimal care if planted in the right location. When planting lily bulbs, it is essential to choose a spot with well-draining soil and access to at least six hours of sunlight per day. Adequate sunlight ensures the development of strong, healthy plants and robust blooms.
To care for your lilies, you should regularly water them during dry periods, ensuring the soil remains evenly moist. However, it is crucial to avoid overwatering, as lilies dislike soggy conditions. Mulching around the base of the plant can help retain moisture and suppress weed growth.
Lilies are susceptible to specific diseases and pests. One common fungal disease that affects lilies is lily disease, which causes oval brown spots on the leaves. To prevent the spread of the disease, affected plant parts should be promptly collected and destroyed. Another fungal infection to be cautious of is basal rot, which leads to the rotting of the roots and base of the bulb. Proper soil drainage and the use of disease-free bulbs can help prevent such infections.
Garden pests like slugs and snails can also pose a threat to lily plants. A preventative measure against these pests is to create a barrier with a layer of sharp grit or wildlife-friendly slug pellets. Additionally, vine weevils can prove fatal to lilies by feeding on the roots and base of the bulb. To detect these pests, it is useful to shine a torchlight at night to spot the grey-brown adult vine weevils that tend to gather along leaf edges.
Common Diseases and Pests of Lilies
One of the key pests that gardeners face when it comes to lilies is the destructive lily beetle. These beetles emerge in early spring and specifically target lilies until June. Adult lily beetles feed on the leaves, while their larvae reside on the underside of the foliage. The larvae coat themselves in their own excrement, creating a protective layer. As they grow, they shred the leaves which can cause significant damage to the plant.
Another common disease that affects lilies is lily mosaic virus, which causes mottled or streaky patterns on the leaves and compromises the plant’s overall health. To prevent the spread of this disease, it is crucial to promptly remove and destroy infected plant parts. Additionally, it is important not to replant lilies in the same spot, as this can allow the fungus to persist in the soil.
Tips for dealing with lily pests and diseases:
- Keep a lookout for lily beetles and manually remove them from the plants
- Regularly inspect the leaves for any signs of lily mosaic virus and promptly remove infected parts
- Dispose of infected plant material properly to prevent further spread of the diseases
Note: Prevention and early intervention are key to maintaining healthy lilies.
Dealing with Lily Beetles
To effectively deal with lily beetles, it is crucial to identify the problem early on. Vigilance is key when it comes to detecting these pests on the leaves of your lilies.
Once they are spotted, manual removal is a recommended method of control. Wear gloves and pick off the beetles, making sure to also remove any larvae and eggs. Drop them in a bucket of soapy water to prevent their return.
If lily beetles are persistent, you can consider using biological controls such as nematodes. These microscopic worms target the beetle larvae, disrupting their life cycle and reducing their population.
Applying insecticides can also be effective, but it is essential to choose an appropriate one labeled for lily beetles and follow the instructions carefully.
- Identify the problem early on.
- Vigilance is key when detecting lily beetles.

Preventing Spread of Infection and Disease
To prevent the spread of infection and disease in lilies, it is crucial to take proactive measures. When observing signs of disease, such as lily mosaic virus, it is important to collect and destroy infected plant parts promptly. This prevents the disease from spreading to healthy plants in the vicinity.
Proper disposal and destruction of infected plants is necessary to prevent the fungus or virus from persisting and potentially infecting future plantings. Additionally, it is advisable not to replant lilies in the same location to avoid the buildup of pathogens in the soil. Instead, choose a different area or consider rotating your planting spots.
Takeaway: Actively monitor and remove any infected parts to prevent the spread of disease.
(–) Proper disposal and destruction of infected plants
