Seeding and fertilising.
The germination blanket is laid. Rain is forecast for tonight, so the seeds should be off to a good start.
Five days on from laying the blanket, and a couple of rain-fronts and a frost have passed. No growth visible so far.
Ten days on from laying the blanket. The weather has been cool with occasional rain. Still no grass growth visible.
Three weeks after seeding. At last a few sparse signs of new grass, but only in a few places around the edges. The germination blanket is now getting pretty scruffy and torn.
Nearly 5 weeks after seeding, and the weather has been quite cold for the last couple of weeks. Nevertheless there's a definite hint of green to be seen in some places, though the germination is still very sparse and the growth slow. Rain is forecast for tomorrow morning, which will be welcome, but then it turns cold again. The germination blanket was pegged back in place a while ago, but it is once again torn and blown back in places, so more repairs needed.
A couple of weeks later, and we have had a pretty cold spell of weather including about 10cm of snow 9 days ago. (It thawed pretty quickly, except where some park visitors evidently enjoyed a construction activity.) The courts are slow to drain at present, especially where the germination blanket remains intact.
Still very waterlogged, and the "blanket" is breaking up in the wind.
Some 7 weeks later. The "blanket" has now been removed, and there are patches where some grass has grown thinly, but ... oh dear! Still very waterlogged after some recent rain. The drainage is evidently now very poor.
