Plant spacing
In a square-foot bed, space alpine strawberry about 4 in apart — that fits 9 plants in each 1-foot square (3×3). Wider rows or containers space the same.

Care & troubleshooting— extension-sourced, with citations
When to feed, prune & water
Mulch to suppress weeds and retain moisture
Mulch- Routine careApply organic mulch around plantsstrong evidence — extension confidence
Spread a few inches of straw, shredded leaves, or compost around established plants (keeping it off stems) to hold soil moisture, suppress weeds, and moderate soil temperature; wait until soil has warmed for heat-loving crops.
Protect the garden from deer
Protection- Routine careFence the gardenstrong evidence — extension confidence
A fence about 8 feet tall and tight to the ground is the most reliable barrier; an outward-angled or double fence, or monofilament line strung at 30 to 36 inches, can also deter deer on smaller beds.
- Routine careRotate repellents as a supplement· every 2 wksmoderate evidence — extension confidence
Where fencing isn't feasible, apply odor/taste repellents and alternate formulations, reapplying every couple of weeks and after rain; combining repellents with fencing works best.
Renovate strawberries after fruiting
Pruning- Routine careMow/trim old leaves and thin runnersmoderate evidence — extension confidence
After June-bearers finish, mow or shear the old foliage, thin crowded plants and excess runners, and topdress with compost to set up next year's crop.
Clean up debris and sanitize at season end
SanitationUnusual this time of year.
- Routine careRemove spent plants and fallen debrisstrong evidence — extension confidence
Pull and clear old plants, dropped fruit, and leaf litter at season end, since many pests and diseases overwinter in this debris; dispose of diseased material rather than composting it.
- Routine careClean tools, stakes, and cagesmoderate evidence — extension confidence
Wash and sanitize stakes, cages, and tools that touched diseased plants before storing or reusing them to avoid carrying pathogens into next season.

Gray mold (Botrytis) on strawberries
Diseasemoderate- CulturalPick clean, mulch, and improve airflowstrong evidence — extension confidence
Harvest ripe berries promptly, remove rotting ones, mulch with straw to keep fruit off soil, and space for airflow. Dry conditions stop it.
Japanese beetles
Pestmoderate- CulturalHandpick into soapy water· every 1 days · ~4 wksstrong evidence — extension confidence
In early morning when beetles are sluggish, knock them into a bucket of soapy water; daily removal also reduces the scent that draws in more beetles. Skip the lure traps, which tend to attract more beetles than they catch.
- CulturalCover plants past bloommoderate evidence — extension confidence
On crops that have finished flowering and set fruit, drape a row cover or netting to keep beetles off without blocking pollination during bloom.
Powdery mildew
Diseasemoderate- CulturalImprove airflow + remove worst leavesstrong evidence — extension confidence
Cut out the most heavily coated leaves and thin for airflow; avoid wetting foliage late in the day.
- OrganicPotassium-bicarbonate or sulfur - label use only· every 1 wk · ~4 wksmoderate evidence — extension confidence
Apply a labeled potassium-bicarbonate or sulfur fungicide weekly per the label. No sulfur within 2 weeks of oil or in high heat.
Spider mites
Pestmoderate- CulturalHose down and raise humidity· every 3 days · ~2 wksstrong evidence — extension confidence
Mites thrive in hot, dry, dusty conditions. Spray foliage (especially undersides) with water to dislodge them and reduce dust.
- OrganicInsecticidal soap or horticultural oil - label use only· every 5 days · ~2 wksmoderate evidence — extension confidence
Apply to undersides per label; mites resist many products, so soaps/oils are preferred. Not in extreme heat.
Aphids
Pestlow- CulturalBlast off with water· every 3 days · ~2 wksstrong evidence — extension confidence
Knock colonies off with a strong jet of water in the morning; repeat every few days. Light infestations rarely need more.
- OrganicInsecticidal soap - label use only· every 1 wk · ~3 wksmoderate evidence — extension confidence
For persistent colonies apply insecticidal soap to undersides per label. Avoid open flowers.
