The ecological habits of California poppy

California Poppy grows in grassy and open areas from zero to 2,000 meters above sea level.

More cold, like cold and dry climate, not easy to hot and humid, should be loose and fertile, well drained, deep upper sandy loam, also poor soil resistance.

California poppy has strong cold resistance, likes cold and dry climate, and can not withstand heat and humidity. It is in a semi-dormant state in hot summer, and often dies, and then germinates after autumn. California poppy belongs to a fleshy straight root system, must be deep loose soil, requires good drainage, large seedlings should not be transplanted. It can sow and reproduce itself.

How to grow and care for California poppy

(1) California poppy root meat, like monotonous, afraid of waterlogging. In the rainy season, the ground should pay attention to timely drainage, potted plants should be watered in appropriate amounts, should not be wet and dry, to avoid the root neck black erosion.

(2) Because California poppy is a kind of plant with long taproots, it is not resistant to transplantation, so it is better to seed seeds in pots.

(3) California poppy sown in spring and flower in summer, but usually grow and flower less well than those sown in autumn. Therefore, sowing should be carried out in summer, and the suitable temperature for germination is 15-20 ℃. If the germination is not neat, more dense seedlings, appropriate thinning. Planting spacing 20-30 cm, planting to high dry, drainage is better. Growing period should pay attention to soil weeding, open winter should take cold prevention measures.

(4) After the skin turns yellow, the fruit should be harvested in time in the early morning, otherwise the capsule will crack automatically, leading to seed scattering. 

Fall care

Seedling of California poppy on the pot after a period of time to recover, the fertilizer and water management to quickly catch up. The fertilizer and water management follows the sequential cycle of "Huabao" -- "Huabao" -- "Huabao" -- "Huabao" -- "Huabao" -- "Qingshui", and the interval period is about 1-3 days. In winter and spring, the interval period is shorter during sunny days or high temperatures, and longer during cloudy and rainy days or low temperatures or no watering.

Winter care

Although California poppy still continues to grow, the lower temperature will slow its growth rate, and it does not require much fertilizer and water, or even control fertilizer and water. Fertilization and water management follows the sequential cycle of "Huabao" -- clear water -- clear water -- "Huabao" -- clear water -- clear water, with an interval of about 4~7 days. The watering time should be arranged as far as possible on sunny days when the temperature is high at noon.

In the spring

After the temperature rises, the California poppy growth recovers rapidly, and gradually enters the stage of flower bud differentiation and flowering, which requires a lot of fertilizer and water. Fertilizer and water management follows the sequential cycle of "Huabao" -- "Huabao" -- "Huabao" -- "Qingshui", and the interval period is about 2~4 days. The interval period is shorter during sunny days or high temperatures, and longer during cloudy days or low temperatures or no watering.After entering the fruiting period, stop the fertilizer supply.


In the process of California poppy flowering, cutting off three leaves of the remnant flower band, can prolong the flowering period.

Water care

With other brews, California poppy water demand is more, but the most afraid of chaos fertilization, concentrated fertilizer and n, p, k, required to follow the "light weight more frequently, and less time and complete nutrition" and "room of dry wet, dry to dry, not stem not watering, watering is drenched the" principles of two fertilization (water), and after fertilization, the evening want to keep the dry leaves and flowers.


California poppies require a day of full daylight to bloom and hold plant vigor. Six hours of unfiltered daylight is imperative for poppy growth, and extra is even better. California poppies that develop in shady spots will appear ratty and succumb to fungal diseases.


The capability of California poppies to develop in areas with negative soil offers them an aspect of survival: whereas different plant life that wants wealthy loamy soil full of vitamins may flounder in depleted soils, California poppies go in to fill this niche. Sandy soils and rocky soils each furnish correct stipulations for California poppies. What would not work is heavy clay soils. California poppies want gorgeous drainage for their faucet roots, so if your soil is clay, attempt raised beds or container culture.

Temperature and humidity

The warming of the soil in the spring, mixed with moisture from spring rains, will set off germination of California poppy seeds. As lengthy as temperatures stay mild, between 50 and seventy five ranges F, California poppies will proceed to grow. In areas with warm summers, California poppy plant life will turn out to be dormant. However, when cool fall temperatures return, flora will regrow and re-bloom from their faucet roots.


No fertilizer is quintessential to effectively develop California poppies, even in areas with bad soil. The addition of chemical fertilizers will purpose extra foliage boom at the rate of blooms.

Growing California poppy from seeds

Sow California poppy seeds the place you intend to develop them outdoors, after the final threat of frost. Press the seeds gently into the soil, watering gently to keep away from dislodging the tiny seeds. Germination takes place in about two weeks. You can distinguish germinating poppy seeds from weeds with the aid of gazing the bluish-green tint of poppy foliage. Thin seedlings to about eight inches apart.

How California poppy propagates

Seed propagation

With sowing method propagation, winter soil does not freeze regional line autumn sowing.In northern areas, seedlings are raised indoors in early spring and emerge in about 7 days under the condition of 15-20 ℃. In the true leaves to develop in time before the seedling on the pot, no frost, take off the pot with soil planting (do not hurt the root, otherwise it is not easy to restore growth. Even death); You can also open the ground before it freezes. With wind barrier protection, the seedlings were unearthed the next year. The California poppy seedling stage should be supplied with sufficient water and nutrients. 

Cutting propagation

California Poppy cutting substrate: is used for cutting nutrient soil or river sand, clay soil and other materials. Family cuttings limited to the condition is difficult to get the ideal cuttings matrix, the use of this site has been prepared and disinfected cuttings matrix; Medium-coarse river sand is fine, but rinse with clean water several times before use.Sea sand and saline areas of river sand do not use, they are not suitable for the growth of flowers and plants.

The choice of cuttings: used for cuttings called cuttings.Usually combined with heart work, pick down the sturdy, no pests and diseases of the top as cuttings, directly with the top cutting.

Disease control for California poppy

California Poppy is not continuous cropping. In high temperature, high humidity conditions, or too much fertilization, can lead to the occurrence of pests and diseases.

Discover the disease, in addition to timely drug prevention and treatment, but also will be pulled out of the disease plant to burn or deep buried treatment.

Pay attention to field hygiene at the same time.
