Ammi majus does need sun to thrive. It prefers to be grown in a location that receives full sun, which is defined as six or more hours of direct sunlight per day. However, it can also tolerate partial shade, which is about four to six hours of direct sunlight per day.
When it comes to planting Ammi majus, it is important to choose a spot in your garden that receives adequate sunlight. This will ensure that the plants receive the energy they need for photosynthesis, which is crucial for their growth and development.
In terms of soil, Ammi majus prefers well-drained soil. It does not like to sit in wet or waterlogged soil, as this can cause root rot and other issues. Therefore, it is important to ensure that the soil drains well and does not hold excessive moisture.
To improve the drainage of your soil, you can incorporate organic matter such as compost or well-rotted manure. This will help to improve the soil structure and allow water to drain freely, preventing waterlogging.
If you are unsure about the drainage of your soil, you can perform a simple test. Dig a small hole in the area where you plan to plant Ammi majus and fill it with water. If the water drains away within a few hours, then the soil has good drainage. However, if the water sits in the hole for an extended period of time, then the soil has poor drainage and may need amending.
In terms of caring for Ammi majus, it is a relatively low-maintenance plant. Once established, it is drought-tolerant and does not require frequent watering. However, during prolonged dry periods, it is important to water the plants to ensure they do not become stressed.
When it comes to saving seeds for future sowing, it is best to allow the seedheads of Ammi majus to fully mature and dry on the plant. This process usually takes several weeks after the flowers have faded. Once the seedheads have dried, you can harvest them by cutting the stems and collecting the seedheads in a paper bag or container.
It is important to store the seeds in a cool, dry place until you are ready to sow them the following year. Properly stored seeds can remain viable for several years, but it is always a good idea to check the germination rate before sowing.
Additionally, it is worth mentioning that Ammi majus seedheads can provide a valuable food source for goldfinches during the winter months. These beautiful birds are attracted to the seeds and will visit your garden to feast on them. Leaving some of the seedheads on the plants can help to support local bird populations and add a touch of wildlife to your garden.
Ammi majus does need sun to grow well, but it can also tolerate partial shade. It prefers well-drained soil and can be grown in a variety of garden settings. By providing the right growing conditions, saving seeds for future sowing, and leaving some seedheads for goldfinches, you can enjoy the beauty of Ammi majus while supporting local wildlife.
