When to plant strawberry
- Transplant out: ~-3 weeks after last frost.
Companion plants for strawberry
Plant with: Bean, Lettuce, Spinach, Borage.
Avoid near: Brassicas.
Common pests & problems
Slugs, birds, spider mites. Straw mulch keeps berries clean and named the plant.
Feeding & fertilizer
N-P-K ratio: Balanced 5-5-5, avoid fresh manure
Organic options: Compost mulch every spring · Blood meal + bone meal before flowering · Kelp meal after harvest
When to feed: Base feeding on a soil test and on how much new growth the plant made last year.
Watch for: Lots of leafy growth but little fruit = too much nitrogen.
N = nitrogen (leaves), P = phosphorus (roots and flowers), K = potassium (fruit and disease resistance). How to read a fertilizer label →
Grower's tip
Pinch runners the first year so the crown builds strength. You'll double yield in year two.

Soil & water for strawberry
Soil & pH
6.0-7.0 for most; confirm with a soil test
Deep, well-drained soil. Standing water around the roots causes root and crown rot.
Test soil before planting and correct pH then. Mulch with compost each spring, kept a few inches off the stem or trunk.
Watering
1-1.5 in / week; 2 in during fruit swell
Drip or soaker at the root zone. Keeping leaves and fruit dry lowers fungal disease.
Check soil 6 in down; water when it is dry there. Drought while fruit is sizing gives small fruit.
Knowing when to harvest
- Fully red across the entire berry: day-old white shoulders never sweeten.
- Pick every 2-3 days at peak. Cut, don't pull. The calyx stays with the berry.
- Chill immediately; flavor peaks the day of picking.
Storing & keeping
Unwashed, single layer in the fridge. 3-5 days. Freeze whole with sugar or make jam within 48 hours.
What to expect
Per plant: 0.5-1 lb per year established; June-bearers concentrated over 3 weeks; day-neutrals steady all season
Troubleshooting strawberry
Hollow, gray-mold berries
Likely cause: Botrytis in wet weather
What to do: Straw mulch under fruit; airflow; remove infected berries daily.
Berries pecked / hollowed
Likely cause: Birds or slugs
What to do: Netting for birds; iron phosphate for slugs; mulch keeps fruit off soil.
Varieties worth the space
Not every name in a seed catalog. These are the ones growers order again, with what each one is actually good at and what it asks of you.
Honeoye
Open-pollinated
June-bearer, heavy and reliable in cold winters; firm enough to sell.
Albion
Open-pollinated
Day-neutral: fruit all season, ideal for containers and market pints.
Seascape
Open-pollinated
Day-neutral with better flavor than most everbearers, and it takes heat.
Mara des Bois
Open-pollinated
Wild-strawberry aroma with modern yield. Grow it for the taste, not the shipping.
Albion (day-neutral)
Fruits all summer, disease-resistant, top commercial variety.
Honeoye (June-bearer)
Cold-hardy, big harvest window.
Alexandria (alpine)
Small, intense flavor; grows from seed; perfect for containers.
Growing strawberry in containers
12 in deep strawberry pot; 4-6 plants; refresh soil annually.

Common questions
Should I remove runners?
First year: yes, all of them. The plant builds crown strength. Year 2+: keep 2-3 runners per plant to replace crowns as they age.
Why are my berries small?
Old crowns (3+ years), drought, or too much nitrogen (all leaves, small fruit). Renovate the bed every 3 years.
