When to Plant Swan River Daisy Seeds in Australia

Brachycome iberidifolia can be grown from seed. You can sow swan river daisy seed from late winter through to early summer, depending on where you are based in Australia. 

For gardeners in Australian tropical and subtropical gardens who would like to start growing swan river daisy from seed, using a propagator, you could sow in July or August. Those in temperate areas of Australia should wait until at least September when the weather is beginning to warm up as they are not frost tolerant. 

Use seed boxes or punnets so you can then transplant the daisy to your garden. Sow a few of the swan river daisy seeds in clumps about 20 cm apart. Because the seeds are so small it is prudent to cover them lightly with some seed-raising mix or vermiculite. Sowing depth should be around 3mm. 

You can also sow seeds directly into garden beds or container pots but do so only after the danger of frost has passed. Seedlings will take between 14-21 days to emerge.

Where to Position Australian Swan River Daisy 

Brachycome iberidifolia are versatile and attractive plants that look fantastic in garden beds, hanging baskets, and container pots. If planting in the garden, consider their height against other plants. 

Annuals look best when grown in informal drifts. Given they are relatively short plants, they typically are placed towards the front of a garden bed as an attractive border. 

It is best to plant Swan River daisies in a full sun position. They will tolerate shade but prefer a sunny spot in the garden. 

Best Soil for Swan River Daisy

Swan River Daisies do well in clay or sandy soil. The soil should be well-drained. There isn’t any real need to add manure or garden compost. If the soil is too rich, the daisies will produce a lot of soft growth but very few flowers. An initial treatment of some liquid fertiliser should be sufficient. 

If planting in container pots or hanging baskets a good premium potting mix works well. Again, it is important to ensure that the pot has adequate drainage so that the potting mix doesn’t become waterlogged.
