Sowing Instructions

California poppies, also known as Eschscholzia californica, are gorgeous and vibrant wildflowers that are a symbol of the Golden State. If you’re planning to grow these beauties in your garden, here’s what you need to know about the best methods and procedure for sowing:

Step 1: Choose the right time

The best time to sow California poppy seeds is in the fall, from September to November. This will give your seeds the winter chill they need to germinate in the spring. You can also sow in the spring after the danger of frost has passed, but you’ll need to stratify your seeds first.

Step 2: Prepare the soil

California poppies prefer well-drained, sandy soil with a pH of 6.0 to 7.5. If your soil is heavy, mix in some sand to improve drainage. Work the soil to a depth of 6 inches and remove any weeds or large rocks.

Step 3: Sow the seed

Watering Requirements

When it comes to growing California Poppies, proper watering is crucial for ensuring these vibrant flowers reach their potential. While they are a drought-tolerant plant, they still require watering to thrive.

The key to watering California Poppies is to give them a deep and thorough soaking once every two weeks during the growing season. This allows the roots to absorb enough water to last until the next watering. However, be sure to adjust watering if the soil is particularly dry or if there has been a lack of rainfall.

A good option is a 10-10-10 fertilizer, which should be applied every four to six weeks during the growing season.

Another option is to use a liquid fertilizer, which can be sprayed directly onto the plants for quick absorption. Opt for a liquid fertilizer that is high in phosphorus, which can help encourage blooming.

It’s also worth noting that California poppies are fairly tolerant of poor soils, so if you’re gardening on a budget or prefer a more natural approach, you may choose to skip fertilization altogether.

Overall, the key to fertilizing California poppies is to go easy and use gentle, all-purpose fertilizers. With the right care, these lovely wildflowers will reward you with stunning, brilliant blooms all season long.

Cover the plant with a frost cloth or plant blanket on cold nights to protect it from freezing temperatures. You can also dig up the plant and transfer it into a container, which can then be moved to a protected location indoors or covered porch.

With a little bit of care and attention, your California Poppy will be ready to wow you with its vibrant blooms next spring!
