New Lawn - cracks
I sowed grass seed last week when the weather was cool and damp - this week we have the opposite...my grass seed is germinationg well and I am watering the area every evening (watering can with fine rose). However cracks are appearing in parts of the seed bed not more than a couple of millimetres wide but they are there. I am thinking this may be due to the hot weather we ware now experiencing - I'm in SE. What should I do? Could I pour horticultural sand into the cracks? Any advice welcome. Thanks.
