When to Plant and Watering
Plant young seedlings in Djeran (mid-Autumn) prior to the Makuru rains (Winter). Avoid planting in the hottest times of the year.
Seedlings should be watered twice a week over their first summer in the garden. It is important to ensure water penetrates down into the root-zone.
We recommend using a soil wetting agent as Perth soils are often ‘water repellent’, or do not absorb water effectively.
A layer of composted, coarse mulch can help in getting your garden started. It will help by reducing water loss and suppressing the growth of weeds.
Native Cornflower are waterwise, drought-hardy plants and do not require supplementary water once established.
Native Cornflower should be grouped with other waterwise, drought-hardy plants.
Feeding and Soil Care
Native Cornflower don’t need fertiliser because they are adapted to grow in our local soils, which are typically low in nutrients.
Plants will benefit from adding some vegetable-based compost (avoid those with manure) into the soil at planting.
As your garden develops, practice ‘cut and drop’ when you prune your plants. The leaf and branch material that falls to the ground slowly breaks down over time, releasing nutrients to help your garden to grow.
