Strawberry Fertilizer

Add 2 Tbs (30mL) per gallon of water and apply every 1-2 weeks in spring and summer, then drop to every 4 weeks in fall and winter. A hose end sprayer set to the 1 oz (30mL) setting works for larger beds, and you can optionally mist leaves with 1 tsp per quart every 1-2 weeks. Mix it into your normal watering routine.

At 1 tsp per quart, the 8 oz bottle makes about 48 watering cans of feed. For a typical shelf of 10–15 plants fed every 1–2 weeks in season, that's several months of feeding — and the 32 oz bottle four times that.

Feeding helps, but small berries usually have a non-nutrition cause worth checking first: crowded plants competing for light and water, too many runners draining energy from the mother plant, or poor pollination in cool, wet weather. Clip excess runners, thin crowded beds, and keep watering consistent while berries size. Potassium in this formula supports sizing once those basics are handled.

Usually one of three things: excess nitrogen from a lawn-type fertilizer pushing foliage over fruit, not enough sun (strawberries want 6+ hours of direct light), or variety timing — June-bearers only fruit once a season. This formula keeps nitrogen moderate and potassium high specifically to avoid feeding the leaf-heavy pattern, but it can't compensate for shade.

Yes — this is a plant nutrient made for edible crops, supplying the same minerals plants draw from any garden soil. Follow the label dilution, avoid contact with skin and eyes when mixing, and rinse picked berries before eating as you normally would. The product itself is not for human or animal consumption straight from the bottle.

Yes, but the goal is different. First-year plants are building crowns and roots for future harvests, so many growers pinch off early flowers on June-bearers to redirect energy into establishment. Feed at the normal schedule either way — the balanced nitrogen and phosphate support root and crown development, and day-neutral varieties can be allowed to fruit lightly their first season.

All of the nitrogen is nitrate nitrogen, absorbed directly by the roots, so it starts working with the first application. Expect greener leaves and stronger new growth within 1-2 weeks. Fruit-level results — better sizing, firmer berries — show on the next flush that develops under regular feeding, typically 3-5 weeks in, since berries already sizing were set before feeding began.
