After summer, pour out the bulbs and store them in a cool and ventilated place. As the weather turns cool in early September, bulbs with buds can be selected and planted in pots. The number of bulbs planted depends on the size of the basin, generally 18 cm pot 1 2, 21 cm 24 cm pot 2 2, 27 cm 30 cm 3 4. Cover the basin with slightly thicker soil, pour enough water after planting, and sprout leaves after about 10 days. Calla lilies like light and fertilizer. During the growth period, potted flowers should be fully exposed to sunlight, fertilizers should be applied every 10 days or so, and phosphate fertilizer should be applied after February to promote the germination of flower buds. Calla lilies like to be warm and afraid of cold, and they can be watered more during the growing period, and avoid drought in the basin soil. After late October, the temperature drops, and it is necessary to move into the sunny place indoors. After the spring is warm, calla lilies can bloom into pure white flowers.

Maintenance methods of calla lilies in summer

Calla lilies are summer dormant flowers, and the leaves gradually turn yellow after blooming from April to May, which is a normal physiological phenomenon. Leaves should be put on the side of the basin after withering and yellowing to avoid rain and promote their dormancy.

These factors in the process of planting summer dormant flowers

1. Maintenance of summer dormant flowers

There are some plants that can not act as usual under high temperature, such as magnolia, tulips, geraniums, daffodils, inverted golden bells, freesia, calla lilies, cyclamen, etc., because the high temperature inhibits the growth of flowers, so it is necessary to dig up the bulbs and put them in a ventilated, dry and cool place after less watering or no watering, it is best not to come into direct contact with sunlight and cover storage with a small amount of slightly wet coarse sand.

2. Lighting

Light is very important for plants, such as rose, peony, sweet-scented osmanthus, jasmine, poinsettia, pomegranate, etc. plants such as chrysanthemum, dahlia, magnolia, mulberry, inverted golden bell and so on should be placed in a place with half of the shade. Plants such as orchids, camellia, rhododendrons, gardenias, begonias, Michelia, orchids, calla lilies, asparagus, evergreen, hanging orchids, hairpins and other plants are afraid of high temperatures and should be placed in places where only a little sunlight or scattered light can be seen.

3. Temperature

Temperature is also a factor affecting the growth of flowers. Summer flowers are not suitable for high temperatures. Too hot weather may lead to dormancy of fallen leaves and delay flowering, so summer flowers like this should be placed in a cool place.

4. Humidity

After talking about the light and temperature, it is followed by humidity; flower planting is very fastidious, so all aspects should be involved. Flowers in summer due to the sun, so water evaporation is also more quickly depending on the plants, some flowers that do not bloom can be watered less; some flowers that like cool and wet flowers can be watered less, it is best not to water at noon, the temperature of watering must be about the same as the temperature of the soil.

5. Fertilization

The principle of fertilization for plants in summer is to apply thin fertilizer frequently, and it is best not to apply fertilizer in the hot sun at noon or in a rainy day. The mature liquid mixed with rice water, rotten eggs and animals can be used as fertilizer to make up for the lack of phosphorus and potash fertilizer.

6. Pruning and shaping

Flowers are easy to grow in summer, if there are some diseases and withered branches, they should be pruned in time, pruning and shaping, not only can form new buds, new leaves, accumulate plant nutrients, ventilation and light, and so on. It can also promote branching and increase the growth of buds.
