How to cultivate potted peonies? the balcony can also be beautiful.

Peony: is a peony family, peony plants, is a perennial deciduous shrub, beautiful flowers, jade smile pearl fragrance, elegant and unrestrained, magnificent, known as "king of flowers" reputation. Most of the peonies raised on the balcony are not well raised, because the peonies like the sun, most of the conditions on the balcony of the family can not reach, and the ventilation conditions are too poor compared to the outdoor, so most of the peonies on the balcony are not raised well, even if they bloom poorly, but if you do the following points, it may also give you a surprise.

First, the choice of basin soil

The basin for raising peony should be large, at least a basin with a diameter of 40CM is needed. The depth of the basin is above 30CM, which can be adjusted according to the plant size. Peonies like to grow in neutral sandy soil that is loose, deep, fertile and well drained. Poor growth can occur in acidic or clayey soils. Rotten leaf soil plus pastoral soil can be used to refine river sand (proportion 2:2:1) and then disinfected by spraying (carbendazim, methyl thiophanate, mancozeb, etc.) to form cultivated soil.

Second, lighting

Sex likes a warm, cool, dry, sunny environment. Like sunshine, but also resistant to semi-overcast, cold, drought, weak alkali, avoid stagnant water, afraid of heat, afraid of direct sunlight. Peony flowers like the sun but are afraid of exposure to the sun, so it is necessary to properly cover the peony at noon in summer, and it is not resistant to severe cold and high temperature. after the end of October, the peony will be placed outside in the leeward and sunny place, so that the buds will break dormancy through low temperature, so as to facilitate the peony flowering. Just changed the basin, hurt the root system, should first put half a shade out, half a month later to see the situation transferred to some places of light intensity, fully recovered after the direct sun, but the midsummer season do not expose to the sun, especially when the soil is dry. Try to let the sun shine on the peonies on the balcony.

Third, watering

Peonies like to be dry and do not like to be wet, so the principle of watering is "do not dry, do not water, water thoroughly". The 3CM on the surface of the basin soil can be watered if it is not wet, and water can flow out from the bottom of the basin. It can be watered once every three days in summer and maybe once a week in winter, depending on the basin soil at home. Watering should be reduced in autumn, otherwise the peony leaves will turn yellow and affect flowering. After entering dormancy in winter, do not water the basin soil if it is not dry.

IV. Fertilization

Peonies like to be fattened, so they should be fattened at least three times a year: the first in early March, the second in the second half of flowering, and the third before winter. With fully mature cake fertilizer, a circle of fertilizer was buried in a trench on the surface of the basin soil around the plant, so that the fertilizer slowly seeped into the basin soil. The new peony can not be fertilized, especially avoid applying thick fertilizer, otherwise its roots will be moldy and die, and some thin fertilizer can be applied gradually after half a year. No fat cake can also buy professional fertilizer, more growth period, less florescence, dormancy period is not on the principle of fertilization.

Planting time and pruning

The planting time of peony should be from late September to early October, that is, it is best before and after the Autumn Equinox, not too early or too late.

When pruning, we should follow the principle of "cutting eight inches with a foot long" to keep enough peony flower buds. Leave full flower buds and get rid of redundant weak buds.

VI. Pest control

Symptoms of brown spot disease: Brown or black markings on the leaves. To treat this disease, Bordeaux liquid can be sprayed once or twice a month, and 3 times if the condition is serious. For seriously infected leaves, cut off and burn them to prevent the disease from spreading.

Symptoms of root rot: root rot. The diseased root can be cut off and some sulfur powder can be sprinkled in the planting hole to replant.

Scale insects are small white insects that live by sucking up plant juices. If the pest is attached to the back of the leaves and stems of the peony, it can be sprayed with 40% omethoate emulsion plus 1500 times aqueous solution.
