How to Grow California Poppy

1. Apply some base fertilizer to the prepared growing soil to provide a certain nutritional supplement, then add a small amount of decayed fallen leaves to ensure a certain humus content.

2. Prepare a flower pot of suitable size; the specific size can be determined according to your own quantity.

3. Completely immerse the flower pot in disinfectant for sterilization for at least 30 minutes. Then take the flower pot out and rinse it with pure water at least three times to ensure there is no residual disinfectant.

4. Then place it in a windy place until it dries. At this time, avoid letting dirt touch the inside of the flower pot, which could cause secondary contamination.

5. Put the sterilized growing soil into the flower pot, but do not fill it too full; it is advisable for the growing soil to account for about 80% of the flower pot's volume.

6. Use a shovel to level the soil surface. Be careful not to press the soil surface hard; just gently level it.

7. Evenly scatter the prepared seeds onto the soil surface. Be careful not to use too much force; it is best to handle them gently. This can ensure the seeds will not be damaged during movement and ensure they have good germination conditions.

8. At this time, pay attention to sowing the seeds evenly, not too many in one area and too few in another. This ensures that each seed has enough space to grow and will not struggle to sprout due to lack of resources, and it also ensures that the grown plants are distributed evenly and will not affect the ornamental value of the whole pot of plants.

9. Finally, cover it with a 1-3 cm layer of growing soil, and use a watering can to water the growing soil until moist. Planting is then complete.

California Poppy Planting Methods

1. Humidity management

California poppy prefers a relatively dry air environment. If rainy days last too long, it is susceptible to infection by pathogens. It is afraid of rain, so keep the leaves dry at night. The most suitable relative air humidity is 40-60%.

2. Temperature and light

Temperature: California poppy prefers a cool climate, avoids intense heat, and is resistant to frost and cold. It is not very strict about winter temperature; as long as it is not exposed to frost, it can overwinter peacefully. It dies when the temperature is above 30°C in late spring and early summer. The most suitable growth temperature is 15-25°C.

Light: In the three seasons of late autumn, winter, and early spring, because the temperature is not very high, it should be given direct sunlight to help it carry out photosynthesis and form flower buds, bloom, and set seed. In summer, if high-temperature weather occurs, it needs to be shaded from about 50% of the sunlight.

3. Water and fertilizer management

Watering: The watering principle for California poppy is: water when dry and stop when wet; when dry, let it dry thoroughly; do not water if it is not dry; when watering, water thoroughly. When watering, be careful to keep the leaves and flowers in a dry state and do not let them get wet.

Fertilizing: Apply decomposed dilute cake fertilizer water once a month to keep the plant growing well. Do not apply too much nitrogen fertilizer, as it easily causes leggy growth. The plant should be ensured complete nutrition, with phosphorus and potassium fertilizer and nitrogen fertilizer applied in small amounts and multiple times.

4. Propagation methods

California poppy has two propagation methods: sowing and cuttings. Sowing can be done in spring and autumn, and cuttings are generally carried out together with pinching.

Precautions for California Poppy

1. California poppy is not tolerant of transplanting

California poppy has a relatively long taproot and is not tolerant of transplanting. Before sowing, apply some decomposed soybean cake as base fertilizer, and sow the seeds directly in the pot. When sowing, gardening enthusiasts should first choose the flower pot well, so as to avoid insufficient space after the California poppy grows larger, which could cause poor plant growth.

2. California poppy is toxic

California poppy is somewhat toxic. Direct contact with its leaves may cause skin itching and bumps; in severe cases, a doctor must be consulted. Eating the fruit may cause symptoms such as vomiting and diarrhea.

During care, prevent mischievous children from touching the flowers and leaves. Gardening enthusiasts should also be careful when caring for it.
