When are blueberries ripe?

When they ripen depends on the variety. Some are ready in early summer and others later. You need to resist picking them as soon as they have turned blue. They need a week to 10 days longer on the bush, in fact, when you can just pass your hand under the berries and they fall off is when they are ready. Since these aren't 'your' bushes, you won't be able to cover them to keep birds off, so you need to keep your eye on them so that you know when to pick them before the birds get them all! More information (for gardeners, mostly, but still useful for the wild ones) here: http://www.ehow.com/how_8302_harvest-store-blueberries.html and here: http://www.gardenguides.com/68808-harvest-blueberry.html

Depending upon when they were planted, you can expect them to ripen during the summer months. They can be available fresh from May to August I think. The price will decrease as they are most available.
