When do calla lilies usually bloom? When is the best season for planting?

Calla lily, Araceae, calla lily is a sturdy perennial herb. Like loose, fertile, humus-rich clay loam. It can be used medicinally and has the effect of clearing away heat and detoxification. So when do calla lilies usually blossom? Which season is the best to plant? Now let's put it in order as follows:

When do calla lilies usually bloom?

The general florescence of calla lotus is about 15 days.

The natural flowering time of calla lilies is 3-8 months.

Calla lilies: winter dormancy from July to August

Safflower calla lily: June

Silver star calla lily: July-August.

Culture methods of calla lilies:

The best propagation time: calla lilies enter the dormant period from June to July, when the bulbs around mature plants can be removed to cultivate new potted plants. The most suitable season for breeding is from August to September. Ramet reproduction must be in autumn, otherwise it is very difficult to blossom in that year, that is, flowering, flowering is also late.

The best growing soil: when calla was cultured, sandy loam soil was used as the main soil, garden soil and rotten leaves were mixed with 1 cm 3 each, and then mixed with 1 cm 5 organic fertilizer. Because the root system grows in the upper part of the sphere, the bottom of the basin soil should be covered with water-permeable slag or coarse-grained sand. With 1/3 of the garden soil and rotten leaves. And add a small amount of organic fertilizer.

Growth humidity requirements: calla lilies like moist and fertile soil.

The optimum growth temperature: the optimum growth temperature of calla lily is 2230 ℃. When the temperature is below 20 ℃, the growth rate of horseshoe will slow down. It may even stop growing. Calla lilies like a warm, humid environment, so pay special attention to keeping calla lilies warm during the winter. Avoid excessive temperature in the greenhouse, especially when the relative humidity is high.

The best growth light: calla lilies should pay attention to the light during flowering. Calla lilies "prefer long light to strong light", especially in summer. So to put it in a place with plenty of light, you can move to a distance from the window in summer. If the horseshoe lotus is not bright enough during the flowering period, it will only bud but not blossom, and even the bud will gradually turn green and shriveled. There is no need to shade the sun in spring and autumn.

Points for attention in culturing calla lilies:

Fertilizer application: lack of fertilizer or excessive fertilization during the growth of calla lilies will cause yellow leaves, so pay attention to the application of base fertilizer (horseshoe slices are the best). Potted plant nutrients are limited, so it is necessary to apply thin fertilizer frequently and constantly supplement potted soil nutrients.

Main points of reproduction: calla lilies are mainly propagated by dividing balls. After the plant enters the dormant period, peel off the small balls around the tuber and plant it separately. It can also be sown and propagated, and the seeds can be sown in pots as soon as the seeds are ripe. The suitable temperature for germination is about 20 ℃.

Ramet: when the old leaves withered gradually after flowering from May to June, and when new leaves grew or changed pots in the middle of September, the small tubers around the mother plant were peeled off and put on the pot by stages. It usually blossoms 3 months after planting.

Sowing: indoor pot sowing is the main method, and the optimum temperature for germination is 18-24 ℃. After 15-20 days of sowing, the seedlings need to be cultivated for 3-4 years before they can blossom.

Pruning essentials: calla is a perennial herb that can blossom many times in a year. Cutting off the old leaves frequently can make them blossom many times.

Pot soil replacement: calla lilies in late June to early August, combined with changing pots, the well-developed large ramets with roots will be broken by hand (preferably without a knife) and planted in a prepared basin. If it is used as a cut flower, 2 or 3 more ramets can be planted and placed in a cool place. Using this method to propagate, it can blossom from September to October of that year.

Watering points: calla lilies are said to be "immortal calla lilies". Because they like a warm and humid environment and are not resistant to drought, the potted soil should be kept moist and should not be short of water. If the environment is dry, spray water to the ground and keep a small moist environment. It should be fully watered during the growth and flowering period. Keep the basin soil moist, but reduce the amount of water after flowering to facilitate dormancy.

Disease and pest control: the tuber of Zantedeschia is prone to rot during dormancy or storage. 1000-fold solution of acetic acid solution can be used to spray the surface of tuber and store it after drying. The pests were harmed by red spiders and thrips, which were sprayed with 1000 times of 50% ethyl acaryl alcohol and 4000 times of 2.5% deltamethrin EC, respectively.
