Planting & stewardship

How to help Desert zinnia thrive

  1. 1

    Plant into native or lightly amended soil rather than a rich, wet garden mix.

  2. 2

    Water to establish, then follow natural wet-dry cycles.

  3. 3

    Tip-prune lightly after flowering if plants become open.

  4. 4

    Avoid burying the crown beneath deep organic mulch.
