Miscellaneous 

Soil

Fertile, well-drained soil.

None. Annual coreopsis cannot tolerate cold temperatures.

Feeding

Mix a light application of a balanced organic fertiliser into the soil prior to planting. Annual coreopsis needs less fertiliser and water compared to other flowers.

Companions

Lettuce and Pomegranate. The narrow, airy plants rise up suddenly in late summer, making them great replacements for early season bloomers. Annual coreopsis is an excellent flower to grow in wildflower meadows.

Spacing

Single Plants: 30cm (11") each way (minimum)
Rows: 30cm (11") with 30cm (11") row gap (minimum)

Sow and Plant

Sow seeds in moist seed starting mix indoors, or wait until after the last frost has passed and plant seeds where you want the plants to grow.

Notes

The bicoloured blooms of coreopsis attract butterflies and beneficial insects.

Harvesting

Snip off spent blossoms to keep plants looking neat, and to prolong flowering. Tall plants benefit from staking.

Troubleshooting

Be patient with this wildflower, which blooms in late summer and autumn. Plants will reseed themselves with a little encouragement.
