Hello dear @oniemaniego, I congratulate you for the excellent work you are doing with the sowing, without a doubt you managed to sow at a correct time, because the rainfall maintained the humidity required by the crops. Clay soils tend to retain the greatest amount of water, which is why developing drains is important.

I recommend you to make compost and integrate it into the soil to improve its structure by providing organic matter, thanks for sharing your experiences have an excellent week.
