A strip is sown for the day it will flower, not the day it goes in. Take the gap's dates, take the plant's days from seed to flower and its days in flower, and count back. The sowing that puts flowers right across the gap is usually a narrow week, and a fortnight early or late leaves one end of the gap bare.

In this game one strip sown in its week closes part of the gap. Two strips nearly close it, and at the middle of the gap they roughly double what the bees find.

The best sowing for the August gap is around Jun 15 for phacelia and around Jun 3 for borage. A plot can book the sowing ahead: the seed is paid for when you book, cancelling gives the money back, and the strip goes in on its day without you.
