How to protect a recently seeded lawon
Thank you for your email.
I assume that you are wanting to protect your seeded lawn from birds eating the seed. With this in mind, bird netting would be ideal. However you would need to suspend this above the ground to prevent birds being able to gain access to the grass. Over an area of 1000 square metres, this could prove to be a challenge.
In the past, I have success laying fleece over a seeded lawn. This will protect it from birds and will also have the added benefit of keeping the temperature up which will aid germination. It is also easy to lay as it simply needs pegging down at regular intervals. Water will get through the fleece, but it will form a slight barrier so you will need to keep an eye on the moisture levels in the soil.
I hope this is helpful. Please let me know if I can be of any further assistance.
