California poppies are typically hardy in USDA zones 6 to 10. These flowers grow at their best in mild temperatures that range from 50 to 75 °F (10-24 °C) all year round. Excessive heat can damage the overall health of your plants and also cause dormancy when not needed.
When it comes to humidity, they prefer low to moderate levels. If you grow California poppies in high humidity, good air circulation and soil drainage are mandatory. These basic requirements can help you prevent fungal diseases and pest infestations.
Although California poppies are carefree plants, stem rot, mold, or powdery mildew can stress them out occasionally. These problems usually occur if you are growing your flowers in wet areas or those with frequent rainfalls. In case of infection, you can treat your plants with proper fungicides. Yet, correcting their growing environment is your best long-term option.
Planting California Poppies
You will notice a lot of California poppies in gardens because these particular settings allow them to grow the same as in their natural habitat. Of course, you can grow these beauties indoors in pots, but they will live for a shorter time. In containers and also hot regions, you will have to treat them as annuals and plant new seeds in the following growing season.
When we are talking about soil, California poppies are not as picky as other flowering plants. These buddies can do just fine in poor substrates as long as they have excellent drainage. Still, make sure you are planting them in sandy or rocky soils and avoid heavy clay ones. If you want to grow your flowers indoors, look for containers that have drainage holes at the bottom.
For both perennial and annual types, less is more when it comes to fertilizers. Even if you provide your California poppies with nutrient-poor soils, they will not need extra fertilizing. In fact, only one feeding is enough to produce excess foliage at the expense of their stunning flowers.
During their blooming period, California poppies will benefit from regular deadheading. You can remove all spent flowers to make room for new ones to flourish beautifully. But if you want your plants to self-seed, you must leave a few flower heads alone to drop some seeds.
Watering California Poppies
What makes California poppies even better is their ability to tolerate long periods of drought. In general, these plants need very little water to thrive and are ideal candidates for beginner gardeners that love a touch of flower here and there.
During their active growing period, in spring, California poppies do well only with just rainwater. If you live in a region with seldom rainfalls provide your flowers with water once every week. During hot summer months, these plants usually go dormant and do not require supplemental irrigation at all.

Propagating California Poppies
California poppies have their innate talent to fill our surroundings with delicate and vibrant flowers. Because of this, it is pretty hard to part ways with them when the time comes. Luckily for us, romantic gardeners, the solution is right before our eyes – propagation! And when it is all so fun and simple, you can also make more of these fellows for your beloved family members or friends.
Since they cannot handle disturbed roots very well and neither stress from cuttings, sowing seeds is the best way to do it. This method requires no past experience or effort, so you will have as many superb California poppies as you want without any trouble. Moreover, the seeds will germinate in a few days after planting, bringing you almost instant feedback on your skills.
You can collect seeds from spent flowers and plant them in autumn or the next growing season, usually in early spring. California poppy seeds germinate better and faster if you sow them in somewhat cooler soils. Due to this fact, you can sow them directly in the ground and let them be for as long as it takes.
We recommend you plant the seeds at a distance of 8 inches (20 cm) to avoid over-crowding the seedlings. After sowing, make sure you water the soil gently to avoid dislodging your tiny California poppy seeds. With proper care, germination should occur in about 10 to 15 days.
In Conclusion
We can tell you a lot of stories about growing poppies, but the best way to find out how charming and easy-going these plants are is to grow them yourself. After all, why wouldn’t you give California poppies a chance? Their hypnotic flowers can make for great additions to both indoor and outdoor settings without much effort on your part. Summertime is almost here, so you surely do not want to miss the chance to satisfy your curiosity about these friendly companions!
