It has been raining quite a lot over the last week or so; enough to make a difference to many spring planted crops which are now looking much better.Coupled with cooler temperatures of late and we currently have a very good growing period.
The dry weather at spring planting and emergence will have encouraged roots to go deep looking for moisture which will mean the root system will be better suited to keeping the crop growing longer during the dry period that will inevitably return.
This is in direct contrast to last years wet spring in which roots didn't go deep because they didn't have to so when the drought hit plants couldn't find water and struggled to keep growing.
That's the theory anyhow.
