Common Strawberry Varieties
Popular cultivars to look for at your local nursery or seed supplier.
Albion
Day-neutral everbearing variety with large, very sweet berries; great for long seasons.
Chandler
June-bearing variety producing extremely large, firm berries with classic strawberry flavor.
Seascape
High-yielding day-neutral with excellent flavor; performs well in both spring and fall.
Alpine Mignonette
Small, intensely sweet woodland strawberry that thrives in partial shade.
Ozark Beauty
Cold-hardy everbearing variety with very sweet, firm fruit; reliable in northern gardens.
Common Strawberry Problems
What to watch for — and how to fix it before it spreads.
Pests
Chew holes in ripe berries overnight; most damaging during wet seasons.
Mulch with straw to keep berries off soil; use beer traps; apply iron phosphate bait.
Pick ripe berries the morning before you can harvest.
Cover plants with bird netting held off the plants on hoops before berries ripen.
Adults notch leaf edges; larvae feed on roots causing stunted, wilting plants.
Apply beneficial nematodes to the soil in spring and fall.
Sucks developing fruit, causing deformed "catfaced" strawberries.
Use row covers; weed perimeter to remove overwintering habitat; apply spinosad.
Diseases
The most common strawberry disease; turns ripe and ripening fruit to gray, fuzzy mush in wet weather.
Pick ripe berries immediately; remove mulch for airflow; avoid overcrowding.
Roots turn red inside and die; plants collapse in spring; worse in wet, cold soils.
Plant resistant varieties; improve drainage; avoid planting in low spots.
White powdery coating on leaf undersides; curled, purple-tinged leaves; common in dry summers.
Improve airflow; apply sulfur or potassium bicarbonate; choose resistant varieties.
Common Mistakes
Uncontrolled runners form a dense mat that reduces airflow and berry size.
Remove all runners the first year to let the mother plant establish; allow limited runners after that.
Crowns buried below the soil surface rot; too-shallow plants dry out.
Plant so the crown (where leaves meet roots) sits exactly at soil level.
Old, dense foliage harbors disease and pests; renovation resets the planting.
After final harvest, mow foliage to 3–4 inches, thin to 4–6 plants per foot, fertilize, and water in.
🌾 Seed Saving Guide
🟢 EasyWhen to Harvest Seed
Let berries fully ripen and begin to dry on the plant, or freeze ripe berries and thaw to extract seeds.
Processing
Blend ripe berries with water, strain out pulp, spread seeds on a paper towel and dry for 1 week.
Seed Viability
Up to 2 years when stored cool, dark, and dry.
Pro Tip
Seeds do not grow true for hybrid cultivars. June-bearers are often OP; everbearers are commonly hybrid — check your variety.
