Like all ferns, Ostrich ferns are plants that will spread fast. Ferns will hit the spring time and burst into action, they will grow quickly and they will also spread relatively quickly as well. Of course this doesn’t happen overnight but do be aware of your ferns spreading.
If left unchecked, Ostrich ferns will spread along the Earth and can soon overrun a garden or nature reserve. But don’t worry, they’re not going to run out of control straight away. You should be able to see your ferns spreading and cut them back as and when is necessary.
If you like a slightly wild look to your garden then feel free to let these ferns spread for a while before chopping them back. However, if you want easy maintenance then definitely stay on top of cutting back your ferns or you will find they spread faster and faster. Another point to consider is that even if you like ferns in your garden others might not be so keen. And if a fern spreads then it is possible for them to spread into other neighbours gardens and past the boundaries of your land. So make sure you keep an eye on this and don’t let your Ostrich fern become invasive.
The time frame that ferns spread can be remarkable quick. In one growing season you may notice ferns sprouting up everywhere. So as a gardener it’s your responsibility to make sure you have this all under control.
