Spider mites are very tiny but can cause huge damage to our garden plants, to know if your canna lily has spider mites look for spider web along with your plant taking on a dusty appearance. What you can also do to further test your finding is to place a sheet of white paper under the plant’s leaves and gently shake or tap.

These garden best are the larvae of the canna lily butterfly, The larvae have a large black shiny head and are yellow in color. Infestation includes the young leaves failing to open along with yellowing of the leaves. The use of Bacillus thuringienis will bring this garden pest under control.
Snails and slugs
Snails and slugs cause damage to canna lilies by eating holes in the leaves which can cause your lilies to look very unattractive. Handpicking them and throwing them into a bucket of soapy water or applying snail bait will bring the infestation under control.
Thrips can cause server damage, I have had many challenging experiences with them. The adult thrips are tiny and slender, with colors of black, brown, or yellow. Their babies resemble the parents and are yellow to light green.
The damage of thrips includes white patches on the plant’s leaves along with streaks and slivery speckling this damage is caused because the fluid is being extracted from the plant by these garden insect pests. A serious infestation may also cause leaf drop, twisting of the leaves, or the leaves being deformed. The use of insecticidal soap will offer some help.

Canna Botrytis Blight
The beginning stage of this disease is white growth on the leaves, fungal spores which are gray and tiny attaches to the flower buds, dark spots also develop on the leaves. Discolored streaks may also be seen along the base of the plant.
Rainy humid conditions encourage this disease. To keep your canna lily free of botrytis blight or to at least bring this disease under control water in the morning because this will allow the plant to dry before dark sets in also water your lily from the soil level and not allowing the water to splash on the leaves.
The removal of infected plant parts including spent or faded flowers and keeping the plant bed free of debris along with the use of a copper-based fungicide will offer some help.
This fungal disease is encouraged by soils that are saturated with water, long periods of humid conditions, and poor air circulation. Symptoms appear as orange spots on the leaves of the canna lily, the upper parts of the canna lily leaves develop a brown-blackish appearance which causes the leaves to drop prematurely.
Installing your lilies in well-drained soil, avoid wetting the plant leaves, giving them a spacing of 1-2 ft along with 6 hours of sunlight will help. Infected plant parts should be removed.
There is no known cure for this disease, the symptoms of this virus shows up as patches of dead leave tissue, stunted plant growth, yellow spots develop between the leaf veins, molted leaves, the flower blooms late, the best option is to dig the plant up from the roots and place it in a tightly sealed plastic bag or burn it. It is also recommended that garden plants that are growing near these infected plants should be dug up and destroyed also.
