Blueberries
Need acidic soil pH 4.5-5.5. Two+ varieties for pollination. Full sun, consistent moisture, acidic mulch. Mature bush: 5-10 lbs/year.
Raspberries
Spread aggressively, use barrier. Full sun, well-drained, trellis. Summer or everbearing. Cut spent canes to ground.
Blackberries
Like raspberries but more heat-tolerant. Thornless varieties for comfort. Trellis, annual pruning.
Strawberries
June-bearing: one crop. Day-neutral: throughout season. Replace every 3-4 years.
Currants/Gooseberries
Thrive in partial shade. Cold-hardy. Great for jams/pies. Check local Ribes restrictions.
General
Amend with compost. Mulch generously. Water during fruiting. Bird netting when ripe. Annual feeding and pruning. Start 2-3 bushes. Homegrown ripe berries make store-bought disappointing.
