Take care of your shape
Although it is a simple specimen to care for and maintain, you must be careful with the shape according to its growth. The usual thing is that at first it grows erect, but with the passage of time it will tend to widen, invading all the space around it.
It is important that you keep it as straight as possible, for this if necessary put some guides that make it not widen excessively. These specimens facilitate their cultivation and care because they allow transplanting with a root ball quite well, thus preventing damage to their roots.
These shrubs can be attacked by aphids , spider mites , and leaf miners. Preventive treatments must be carried out in the spring with specific insecticides and acaricides .
To provide the desired shape to the plant, either as a shrub or as a small tree, it must be pruned after flowering. In winter, pruning can be intense in very mature specimens, although without logging.
It reproduces by means of seedlings with roots that grow around the trunks. It can also be multiplied by bud grafting, but not by woody cutting, a system widely used for other shrubs.
Varieties and flowering
This shrub plant has multiple varieties, the fruit of crosses and hybridizations, which promote flowers with different nuances to those of the mother plant. Sometimes they are such radical changes in the shape and size of the leaves and flowers that they seem to have no direct relationship between the two.
For lilacs to bloom in spring, they must be planted in fall or winter. The flowers are lilac, although there are also white, pink or violet. Another feature is its tubular shape.
After flowering, flowers that are dry or appear wilted should be removed so that they do not hinder the normal development of the plant. Dead branches and older branches must also be removed.
Lilacs are extremely easy to transplant. The whole spring period is ideas for this task, since from the time the lilac bushes develop their buds until they take out small leaves, it is a good time for transplanting.
- Decide on the new location where you want to place the shrub or shrubs.
- Nail a hole about 30 cm. wide for each bush to be transplanted.
- Take a lilac bud from the main bush; use a shovel to remove the slice; Choose a 20 to 25 cm bud. tall, if you cut it smaller than this measure it will take a long time to mature until it flowers. Sprouts larger than the recommended size will take longer to recover from the transplant and recover.
- Put the sprout in a bucket of water if you’re not going to transplant it right away, so it won’t dry out. If you transplant it right away, take it to the hole you’ve dug and put it there.
- Place the sprout in the center of the hole and fill it with soil. Leave a depression of about 8 cm. around the sprout to have a reservoir of water.
- Water it with about 5 or 6 liters of water several times a week throughout the season so that the bush adapts well to the new soil.
A new lilac bush takes 4 to 5 years to grow and flower.
Pests and diseases of lilo
- Bacterial wilt: Leaves or black spots are observed on leaves and also on shoots. The cause is a Pseudomonas syringae bacteria . Prune all the blackened twigs and burn them. Then it is convenient to spray with copper broths
- Mottles and spots on the leaves: The Ascochyta syringae fungus causes more or less rounded spots on the leaves in autumn and with a diameter of 1-2 centimeters , which can get together.
- Powdery mildew .
- Necrosis in the cortex.
- Necrotic spots or black spots are observed on diseased twigs , with death of the buds and drying of the inflorescences.
- The leaves of the young shoots also turn black and fall. The cause is the fungus Phytophthora syringae, which invades cambium . The disease can cause significant damage to Lilos of all ages.
- Cut off the diseased shoots on the healthy side and burn them. It sprays in spring, towards April-May, especially if the weather is rainy, with copper or dictiocarbamate fungicides . Repeat the treatment if the rains persist.
- Virosis .
- Small leaves with yellow spots that are also generally curled or deformed. It is incurable, destroy the plant.
- Frost damage.
- In spring , young leaves can be damaged by the low temperatures of late frost.
- Mealybugs .
- Mining moth .
- Small caterpillars of Garcilaria syringella . It is light in color and about 8 millimeters. In their spring generation they gnaw on the buds and those of the 2nd generation, in summer, they dig galleries in the leaves, which are then rolled up and joined by silk threads.
- Spray the spring generation with a phosphor and the summer with a penetrating action.
- Cantharids .
- Lytta vesicatoria attacks Lilo’s leaves.
- Weevil .
