HOW TO GROW

GRASS TREES

Step 1

Sow in warmer climates anytime, for colder

climates wait until the last frost is gone.

Start in 10cm (4") pots.  Use a well 

draining sandy soil mix preferably.

Plant 2-3 seeds flat on the

soil of each pot and cover lightly (about

the width of the seed) with more soil. 

Step 2

Water gently and then cover each 

pot with some plastic wrap (glad wrap) to keep the

moisture and humidity inside the pot.

Step 3

Place pots in a warm location to germinate and be 

sure to keep the soil moist - NOT wet.

Germination should occur if ideal conditions are provided 

between 4-8 weeks.  Once sprouts begin the plastic 

wrap can be removed.

 Step 4

When fertilising us a native wildflower fertiliser.

Seedlings can be planted out once they

are well established around 1+ years old.
