Late June is a time for harvesting vegetables from early sowings.
If you have not already done so, you should plant brassicas for autumn crops, either those you have grown yourself or modules I have raised; we have kale and calabrese.
For those with their own plots think about winter and spring veg such as sprouts and purple sprouting broccoli.
Beds can often be used twice in a season, such as module raised brassicas replacing early potatoes and broad beans.
