The pyrethrum is a beautiful daisy-like flower that can add splashes of white, pink or red to any garden or landscape. This flower also acts as an effective, natural repellent to many types of insects and pests. Growing these plants is not very difficult, but there are several things that you need to take into consideration when sowing pyrethrum seeds.
Pyrethrum Seed Sowing
You should only sow pyrethrum seeds in areas that receive a lot of direct sunlight. Although these flowers will grow in colder regions, you will find that the warmer the climate, the more natural insect repellent that the flower will contain.
Sow pyrethrum seeds after the season's last frost. Place the seeds at least 3 to 4 inches apart with a thin layer of soil covering them. A common rule of thumb for sowing pyrethrum seeds is that you should use twice as much soil as the size of the seed.
Also, make sure to keep the area moist and composted. Pyrethrum seeds will usually germinate in about 7 to 10 days, and you can transplant them when the seedlings are about 2 Inches high.
