Plant strawberries in spring or fall, spacing them 12 inches apart in soil mixed with compost

Strawberries grow well in raised beds because the soil drains fast and stays warm. Plant them in early spring (as soon as the ground thaws) or in early fall (six to eight weeks before the first frost). Space each plant 12 inches apart in rows, leaving 18 inches between rows so you can walk and pick without stepping on plants. The soil should be a mix of garden soil and compost — roughly equal parts — because strawberries need rich, loose ground to spread their roots.

Before planting, remove any weeds or grass from the bed and rake the surface smooth. Dig a hole for each plant just deep enough that the crown (the thick part where leaves meet roots) sits at soil level — not buried, not sticking up. If the crown is buried, it will rot; if it is exposed, the plant will dry out. Water each plant right after planting and keep the soil moist for the first two weeks while roots establish.

Key Takeaways

  • Plant strawberries 12 inches apart in spring or fall, with the crown at soil level — neither buried nor exposed.
  • Mix your raised bed soil with compost so it drains well and holds nutrients strawberries need.
  • Water new plants regularly for the first two weeks, then switch to deep watering once or twice a week depending on rainfall.
  • Pinch off flowers the first year so the plant puts energy into roots and runners instead of fruit.
  • Mulch around plants with straw or wood chips to keep soil cool, reduce weeds, and protect berries from dirt.

Soil preparation and spacing in the raised bed

Strawberries do not tolerate soggy soil, so drainage matters more than fertility. Fill your raised bed with a mix that lets water move through: combine garden soil, compost, and perlite or coarse sand in roughly equal parts. If your garden soil is heavy clay, use less of it and more compost and perlite. The bed should be at least 8 inches deep, though 10 to 12 inches gives roots more room and makes the bed easier to maintain.

Space plants 12 inches apart in rows, with 18 inches between rows. This spacing looks sparse when you first plant, but strawberry runners will fill the gaps by mid-summer. If you crowd plants, air does not circulate, leaves stay wet, and fungal disease spreads fast. Closer spacing also makes picking harder and increases rot on berries that touch the soil.

Before you set plants in the ground, water the bed so the soil is moist but not waterlogged. This helps roots make contact with soil and reduces transplant shock. If you are planting bare-root strawberries (roots with no soil), soak them in water for 30 minutes before planting so they absorb moisture.

Planting depth and initial watering

The crown of the strawberry plant — the thick, woody part where the leaves emerge — must sit exactly at soil level. Dig a hole deep enough that when you set the plant in, the crown is neither buried nor raised above the surface. If you are unsure, err slightly high; a crown that sits a quarter-inch above soil is better than one buried an inch deep.

Gently spread the roots in the hole so they point outward and downward, not coiled or bunched. Fill the hole with soil, press gently to remove air pockets, and water when ready. The water settles soil around the roots and tells you if the crown has sunk — if it has, pull the plant up slightly and add soil underneath.

Water new plants every day or every other day for the first two weeks, keeping the soil moist to a depth of 3 to 4 inches. After two weeks, roots have established enough that you can switch to deeper, less frequent watering — once or twice a week depending on rainfall and heat. Overwatering after establishment invites root rot and fungal disease.

Managing flowers and runners in the first year

Strawberry plants flower within weeks of planting, and the temptation to let them fruit is strong. Resist it. Pinch off all flowers the first year so the plant puts energy into developing roots and runners instead of berries. A strong root system and a few daughter plants (the small plants that form on runners) will produce far more fruit in year two than a weak plant that spent itself fruiting in year one.

As runners emerge — long stems with a baby plant at the tip — decide whether to keep them or remove them. In a raised bed, you have two options: let runners root into the soil to fill gaps and create a dense mat, or cut them off to keep plants in neat rows. A mat system produces more berries but is harder to weed and pick. Rows are tidier and easier to maintain. Choose one method and stick with it; a mix of both looks messy and wastes plant energy.

If you keep runners, let them root into the bed soil. Once a daughter plant has rooted and grown a few leaves, cut the runner connecting it to the mother plant so it becomes independent. This usually happens four to six weeks after the runner appears.

Mulching to protect plants and fruit

Once plants are established (about three weeks after planting), spread mulch around them to keep soil cool, suppress weeds, and prevent berries from touching bare soil. Use straw (not hay, which contains seeds) or wood chips, laying it 2 to 3 inches thick around each plant but not touching the crown. Mulch also moderates soil temperature swings, which matters in spring and fall when frost can damage new growth.

Straw is the traditional choice because it breaks down over the season and adds organic matter to the bed. Wood chips last longer but take years to decompose and can tie up nitrogen as they break down — add a bit of compost or a balanced fertilizer if you use chips. Avoid rubber mulch and dyed wood chips; they do not break down and can leach chemicals into soil.

Refresh mulch in late spring as the first layer compacts and breaks down. By fruiting season (late spring or early summer), a fresh layer of straw under the plants will catch berries and keep them clean and dry.

Watering and feeding through the growing season

Once plants are established, water deeply once or twice a week depending on rainfall and temperature. In hot, dry weather, you may need to water more often. The goal is to keep soil moist 3 to 4 inches deep without waterlogging it. Water at the base of plants, not on the leaves, to reduce fungal disease. Early morning is the best time because any water that does touch leaves will dry quickly.

Strawberries are not heavy feeders, but they do benefit from compost worked into the bed before planting. If growth looks slow or leaves are pale, side-dress plants with compost in late spring or explore a balanced fertilizer (such as 10-10-10) at half strength every three weeks during the growing season. Avoid high-nitrogen fertilizers, which promote leaves at the expense of flowers and fruit.

Dealing with pests and disease in raised beds

Raised beds offer some protection from soil-borne pests, but strawberries still attract slugs, spider mites, and fungal diseases. Check plants weekly for damage. Slugs leave irregular holes and a slime trail; hand-pick them in the evening or set beer traps (shallow dishes of beer sunk into the soil). Spider mites cause yellowing and fine webbing on leaves; spray with water or neem oil if damage is heavy.

Fungal diseases like powdery mildew and leaf spot thrive in humid, crowded conditions. Prevent them by spacing plants properly, removing dead leaves, and watering at the base only. If disease appears, remove affected leaves when ready and improve air circulation by thinning runners. Fungicides are rarely needed in a well-maintained raised bed.

Birds and squirrels may eat ripe berries. Netting over the bed during fruiting season is the most reliable defense. Drape netting loosely so birds do not tangle in it, and remove it on cool mornings so pollinators can reach flowers.

Replacing plants after two or three years

Strawberry plants decline after two or three years of production. Yields drop, berries shrink, and disease pressure increases. Plan to replace the bed or at least half the plants every two to three years. You can let daughter plants from runners take over (they are genetic clones of the mother), or buy new plants from a nursery. Buying new plants is safer because it avoids carrying over disease and pests.

When you replace plants, refresh the soil by removing the top 4 to 6 inches and replacing it with fresh compost and garden soil. This removes accumulated disease spores and pest eggs. If you are keeping the same bed, add a balanced fertilizer to the new soil so plants start strong.

Frequently Asked Questions

Can I plant strawberries in summer?

Summer planting is possible but not ideal. Plants will struggle in heat and may not establish strong roots before winter. Spring and fall are better because temperatures are mild and moisture is more consistent. If you must plant in summer, shade new plants for the first week and water daily.

How deep should a raised bed be for strawberries?

Eight inches is the minimum; 10 to 12 inches is better. Deeper beds give roots more room, hold moisture longer, and are easier to maintain. Shallow beds dry out fast and limit root development, which reduces yields and makes plants more stressed.

Should I remove all the runners or let some grow?

That depends on your goal. Letting runners root creates a dense mat that produces more berries but is harder to manage. Removing runners keeps plants in neat rows and makes picking and weeding easier. Choose one method and commit to it; switching back and forth wastes plant energy.

What is the best fertilizer for strawberries in a raised bed?

A balanced fertilizer like 10-10-10 works well if plants look pale or weak. Compost mixed into the bed at planting usually provides enough nutrients. Avoid high-nitrogen fertilizers, which push leaf growth at the expense of flowers and fruit. Side-dress with compost in spring for a gentler, slower-release option.

Why are my strawberry plants wilting even though the soil is moist?

Wilting in moist soil usually signals root rot from overwatering or poor drainage. Check that the crown is not buried and that the bed drains well. If the soil feels soggy, let it dry out slightly between waterings. If rot has set in, the plant may not recover; remove it and replace it with a healthy one.
