Spring is generally not a problem with lots of grasses seeding and during the summer I have a patch of crab grass that seeds prolifically and responds well to harvesting. I am collecting the excess and freezing what I can.
Are there any grasses that are likely to seed during Perth's winter?
On a separate note my green panic has recently seeded, but the head is very sparse.

Is this a cultivation issue, time of year or perhaps it is just not getting enough sun.
Sorry about the poor photo
Any horticultural assistance would be appreciated.
Cheers
Brett
