First of all, seeds get it all wrong from April till September, according to regions - Always after last frost(gel)
The sowed
Seeds, if you buy several kind of differentes seeds, will owe beings planted by sector : the biggest at the bottom (lucerne), the smallest (white clover, dandelions) in front of or in the middle: this to avoid that the biggest take all the light...
If you buy the 100 gram's bag, you will throw your seeds in the air, by spreading well your seeds (100 gr = 100m2 approximately).
Before sowing your seeds, I recommend you to turn well the soil, take off all the herbs, the pebbles. Do not compress the soil before having to sow - Sow on the soil in the air, choose one day without wind.
Watering
Seeds are now soiled (if you do not use everything, you can keep them for the réfrégirator) - Compress the ground with a roller with lawn or use a piece of wood and walk on it to compress the earth soil without making holes you can spray in drizzle, without putting it too much because if seeds float, they are going to be taken by the water, so spray enough to moisten well the soil but not too much. For a perfect seeding, the ground will have to remain wet constantly, so often spray.
The end
Seeds are going to germinate in one-2 weeks according to the temperature - Continue to spray every day until plantations reached 3/4 cm - Then, space out the waterings
