Ageratum: landing
Landing ageratum in open ground begin to hold when
passes the threat of night frost. Land for landing choose
protected from the wind and sunny – in the shade shoots will be pulled out
and the plant will lose its compact form. Soils ageratum
prefers well-drained, friable, fertile. Perfect
for the well-being of this flower will be sandy loam and loam with a neutral
or weakly alkaline reaction.
Plants are planted at a distance of 0.1-0.15 m each other, between
rows leave 0.2-0.25 m. Flowering will begin in about 2
months after landing.
Ageratum: cultivation
You can grow ageratum to seed, and grafting.
Due to its thermophilia this flower is in Russian climatic
conditions grown seedlings. For this, purchased or collected
own seeds in the second decade of March are sown in boxes. Priming
make up of equal parts of humus, peat and sand. Scattered
seeds on the surface of the substrate, sprinkle them on top with a thin layer
sand and cover with glass or film. Keep seedlings warm
indoors (air temperature must be at least + 15 ° C). As

necessary to air landing. After shoots appear
(in 10-12 days), a covering from a box clean.
Seedlings ageratum
Seedlings dive into separate pots at stage 4 of these

acclimatization.
Growing ageratum cuttings
To grow new plants from cuttings, blooming bushes
at the end of the summer, the ageratum is being dug up together with the earthy clod and
rolled over into pots. Keep them in indoor conditions for
throughout the winter, placing as close as possible to the source of natural light
or by organizing additional lighting. Watered moderately

irrigation water (the dose recommended on the package is reduced by 4
times).

after the spring frosts end.
Ageratum: care
Care of ageratum is not difficult. It is watered moderately – when
Overmoistening is highly likely to develop fungal diseases.
After watering, the land in the garden is loosened and at the same time weeds are removed.
Every 2-3 weeks of planting ageratum is fed with mineral
fertilizers. However, it is important not to overdo it, otherwise the plants
will increase the foliage to the detriment of flowering.

as fertilizer for ageratum fresh manure.
To bloom ageratum was abundant, it is necessary to cut
faded inflorescences.
Diseases and pests ageratum
When agrotechnics are disturbed, the root is often affected.

sporiferous mycelium. When detecting the first signs of the disease
flowers should be treated immediately with fungicides (Topaz,
Fundazol, Bordeaux liquid, etc.). If the measures taken are not

One more of common diseases of many plants and

mosaic infestation of plants on the leaves appear yellow spots or
white color. There is no specific treatment for this disease. AT
As a preventive measure, it is important to weed in time,
use for sowing healthy seeds, fight
insect pests.
AT жарком и влажном климате (южные регионы) агератум часто
поражается бактериальным увяданием. Fabrics
an infected plant is cracking, evaporation is increasing
moisture and reduced turgor. On the leaves appear yellow spots with
brown border. If you cut the sheet across, you will see
dark affected vessels. Because of this, sap flow in the
plant and it die prematurely.
Bacterial wilting ageratum
Bacterial wilt can be cured only in early
stage. To do this, use the drug Coronet. Prevention
is to use healthy planting material,
growing wilting resistant varieties.
Whiteflies, nematodes, spiderweeds live on pests on it.

feed on the plant sap, causing it to fade,
lags behind in growth and dies when the measures are taken. For destruction
whiteflies use insecticides (Aktara, Biotlin, Admiral,
Aktellik and others).

problematic because they are quite tenacious and quickly produce
resistance to pesticides. Therefore, when using acaricides
(Flyoverm, Aktellik, Fufanon) they must be alternated.
Gall nematodes damage landing of the ego-tumum underground. They
damage the root system, plants are stunted, leaves
die prematurely and fall off.

To combat these pests, the land under the ageratum bushes
watered with Tiazo, Bi-58, Rogor (at the doses indicated in the instructions for
drugs).
