How to Grow Strawberries: June-Bearing vs Everbearing, Runner Management and the pH That Maximises Yield
Learn how to grow strawberries at home — from choosing the right variety to planting, feeding, renovation, and harvesting a bumper crop each year.
According to University of Minnesota Extension, a single June-bearing strawberry plant can produce up to 120 daughter plants in one season [1]. The plants practically want to take over — and with the right setup, you can let them.
Strawberries are among the most rewarding home fruit crops per square foot, and no supermarket punnet comes close to a berry picked an hour ago at peak ripeness. But they’re also one of the most mismanaged. The planting is simple; the problems come later — misshapen fruit, plants that barely crop in year two, beds that quietly decline by year three. Almost every one of these problems traces back to a handful of decisions made at the start.
This guide covers the full growing cycle: choosing the right type for your situation, preparing your soil correctly, planting at the precise depth that separates a thriving plant from a rotting one, managing water and nutrients through the season, and running the annual renovation that most gardeners skip — and then wonder why their bed failed.
Choose Your Strawberry Type First
This is the decision that shapes everything else — your care calendar, your harvesting window, and how you manage runners. There are three main types, and they behave very differently.
Seasonal Garden Calendar
Know exactly what to plant, prune and sow — every month of the year.
June-bearing strawberries produce one concentrated harvest, typically two to four weeks in late spring to early summer [1]. The crop is large, the berries are large, and the flavour is generally the best of the three. The tradeoff: you get nothing the rest of the year, and these plants require annual renovation to stay productive. Best if you want to freeze or preserve a big batch, or if you have a household that goes through fruit quickly. Good varieties include Honeoye (early, very reliable), Earliglow (exceptional flavour), and Jewel (high yield) [1].
Everbearing strawberries produce two crops — one in early summer, one in early autumn [2]. Berries tend to be smaller, but you get fruit over a much longer window. These suit gardeners who want a steady trickle of fresh strawberries rather than one big glut. Ogallala and Ozark Beauty are reliable everbearing choices.
Day-neutral strawberries fruit continuously from late spring through autumn, stopping only when temperatures consistently exceed 75°F (24°C) or drop to freezing. They’re less dependent on day length to trigger flowering, which makes them the best option for containers and small spaces. Albion and Seascape are popular, widely available day-neutrals [1].
One practical note before moving on: day-neutral and everbearing varieties need all their runners removed throughout the season, because runner production directly competes with fruit production. June-bearing plants can afford to be more generous with runners, especially from year three when you want to refresh the bed.
Picking the Right Spot
Strawberries need full sun. The minimum is six hours of direct sunlight per day, but eight to ten hours gives you bigger, sweeter fruit [1]. A south-facing slope or raised bed that catches morning sun is ideal — the fruit ripens faster, and there’s less moisture sitting on leaves overnight.
One detail most guides don’t cover: avoid frost pockets. Strawberry flowers are damaged at 30°F (-1°C), causing what the RHS calls “black eye” — the centre of the flower turns black and no fruit develops, even though the plant looks perfectly healthy [3]. Low-lying spots, ground at the base of slopes, and sheltered hollows all pool cold air on still, clear nights. I’ve seen healthy plants in a beautiful sunny bed produce almost nothing because one late-May frost settled in that corner of the garden. If your chosen spot tends to sit cold on clear spring nights, find somewhere else or raise your growing surface.
Rotation matters. Don’t plant strawberries where tomatoes, peppers, aubergine, or potatoes have grown in the past three to four years. All of these share Verticillium wilt, a soil-borne fungus that persists in the soil and infects strawberries — with no cure available once it’s established [1].
Containers and raised beds are genuinely good alternatives for problem soils or small gardens, not just a consolation option. They give you control over drainage and pH, and they significantly reduce slug damage and soil-borne disease pressure [3].
Preparing Your Soil
Strawberries are particular about their soil chemistry. Get this right before you plant and you’ll avoid most of the common problems that show up six months later.
Target pH: 5.5 to 6.5, with 6.0 being ideal [1][2]. Outside this range, nutrients — particularly iron and phosphorus — become chemically unavailable even when they’re physically present in the soil. An iron-deficient plant shows yellowing between the leaf veins and produces poor yields, and adding more fertiliser doesn’t fix it if the pH is wrong. A soil test costs very little and removes all guesswork. Your local county extension office often provides testing for a small fee, and the results will tell you exactly how much lime (to raise pH) or sulphur (to lower it) to add [2].
Drainage is non-negotiable. Strawberries prefer deep, well-drained, loamy soil — ideally sandy loam [4]. As Penn State Extension notes, around 90% of strawberry roots sit in the top six inches of soil, making the plants sensitive to both drought and waterlogging [4]. If water pools after rain, root rot follows quickly. On clay soil, build raised mounds or use raised beds. On sandy soil, incorporate several inches of well-rotted compost or manure to improve moisture retention.
Before planting, dig in 3 to 4 inches of compost and work it into the top 12 inches. This improves drainage in clay, moisture retention in sand, and feeds the soil biology that helps young roots establish.
Planting — The Crown Rule
This is where most beginners make the critical mistake, and it’s completely avoidable once you know what to look for.
The crown is the firm central growing point just above the roots — the point from which leaves emerge. It must sit exactly at soil level: roots fully buried, crown sitting above the soil surface [1].
- Crown buried too deep: it suffocates, moisture accumulates around it, and the plant rots within weeks. It may look fine for two weeks, then simply stop growing and collapse.
- Crown too shallow: the roots dry out and can’t anchor properly. The plant struggles to establish and may heave out of the ground after a frost.
When planting bare-root transplants, build a small cone of soil in the planting hole, drape the roots over it so they spread outward and downward, then fill in firmly around the roots. Check the crown is sitting right at the surface level before you move to the next plant. I made the crown-too-deep mistake on my first planting — everything looked fine for two weeks, then three plants simply stopped growing and eventually rotted at the base. The only fix is replanting at the correct depth.
Spacing: 12 to 18 inches between plants within the row; 3 to 4 feet between rows [1]. This looks wasteful at first, but strawberries spread aggressively through runners, and crowded plants develop poor airflow that directly leads to grey mould on the fruit.
Timing: Plant as soon as the soil can be worked in early spring — typically March to May depending on your climate [4]. Bare-root plants establish well in cool soil. Potted plants can go in later, into June. For help timing strawberries alongside the rest of your spring garden, see our complete spring planting guide.
First-year blooms: If you’re growing June-bearing strawberries, pinch off any flowers that appear in the first growing season [1][2]. This feels counterintuitive — you want fruit, not more leaves — but the plant needs to put energy into building a strong root system before fruiting. The following year’s harvest will be dramatically larger as a result. Everbearing and day-neutral types planted in early spring can be allowed to fruit lightly in their first year.
Watering and Feeding
Strawberries need around 1 to 1.5 inches of water per week, with consistent moisture being more important than volume [1][4]. The two most critical windows are during establishment (the first two weeks after planting) and during flowering and berry development — drought stress at either point directly cuts your harvest.
Drip irrigation or soaker hoses are significantly better than overhead watering. Wet leaves and wet fruit invite grey mould (Botrytis), the most common disease problem in strawberry beds. If you’re hand-watering, water at the base of plants and do it in the morning so any splash dries off quickly. Straw mulch on the soil surface after planting reduces moisture loss, suppresses weeds, and keeps developing berries off the ground.
Feeding — and why timing matters more than quantity:
Most gardening guides say to fertilise after harvest. That’s correct. But the reason why is rarely explained — and understanding it will make you a significantly better strawberry grower.
Research on nitrogen uptake in strawberries shows that nitrogen absorbed in late summer and early autumn is primarily directed into flower bud development for the following year’s crop [5]. Spring-applied nitrogen, by contrast, goes predominantly into vegetative growth — more leaves, more runners, but not necessarily more flowers or fruit [5].
In practical terms: don’t apply nitrogen-heavy fertiliser to June-bearing strawberries in early spring. It pushes lush green growth at exactly the wrong moment, suppressing the flowering response you need. Instead, apply a balanced fertiliser immediately after harvest in summer, then a further application in early autumn. The plant banks that nitrogen through winter and directs it into flower buds for next year.
During active fruiting, switch to a high-potassium feed — the type marketed for tomatoes works well — to improve sugar development and fruit size. Keep nitrogen low during this period [4].
Managing Runners
After your first flush of fruit, strawberry plants send out long trailing stems called runners that root wherever they touch the soil. Each rooted runner is a genetic clone of the mother plant — free propagation material or an energy drain, depending on what you want.
In your first two seasons, remove runners as they appear [4]. A plant producing runners is not producing fruit, and the trade-off isn’t worth it until the bed is well established.
From year three, you can start selecting runners to replace ageing mother plants. Peg the first runner from each plant — the one closest to the mother — into a small pot of compost buried flush with the soil surface. Once it has rooted and produced a rosette of leaves (usually four to six weeks), sever it from the mother. You now have a healthy young plant at no cost.
For day-neutral and everbearing varieties: remove all runners throughout the entire season, every year. These types fruit best with their energy undivided.
Growing the right plants alongside your strawberries can also improve yield and reduce pest pressure naturally. Our strawberry companion planting guide covers which neighbours work best and why.
When pests do strike despite good growing conditions, choosing the right treatment matters — especially on an edible crop. Our guide to the best pest treatments for strawberries ranks five options by pre-harvest interval, efficacy, and safety for beneficial insects.
Annual Renovation — The Step Most Gardeners Skip
If there’s one practice that separates a bed that produces well for four or five years from one that collapses after two, it’s renovation. And most home gardeners either don’t know it exists or skip it because it looks brutal.
Immediately after the June-bearing harvest ends, cut or mow all foliage back to 3 to 4 inches above the crown. Then:
- Narrow rows to 6 to 12 inches wide
- Thin plants to roughly one every 3 to 4 inches, keeping vigorous daughter plants and removing old mother plants that are three to four years old
- Remove all weeds thoroughly
- Apply a balanced fertiliser at the rates recommended on the pack
- Water well and keep the bed consistently moist through late summer
The reason timing is critical: the canopy that grows from August through October determines how many flower buds form for next spring [4][5]. Start renovation immediately after harvest and your plants have 12 to 14 weeks to rebuild. Delay into late August and you’ve cut that window roughly in half — fewer buds, smaller crop next year.
Everbearing and day-neutral varieties are handled differently: rather than mid-season renovation, simply remove old, woody plants after the final autumn harvest and replace with rooted runners.

Pests and Common Problems
Grey mould (Botrytis cinerea) is the most common problem in home strawberry beds. It shows as fuzzy grey growth on ripe or damaged fruit and thrives in cool, wet conditions with poor airflow [1]. Prevention is the only practical approach for home gardeners: use drip irrigation, space plants properly, harvest frequently (removing ripe and any damaged fruit immediately), and keep straw mulch away from the crowns themselves. There is no effective spray fix once it takes hold.
Slugs are particularly damaging in cool, wet climates. They feed on ripe berries at night and are hard to spot during the day. Straw mulch creates some slug habitat — it’s a genuine trade-off. Iron phosphate slug pellets, copper barriers, and nightly checks with a torch help significantly.
Tarnished plant bug feeds on developing fruit, producing misshapen “cat-faced” berries that are edible but irregular and undersized. Removing leaf litter and weeds around the bed reduces overwintering habitat [1].
Spotted wing Drosophila (SWD) is an invasive fruit fly that lays eggs inside ripe and near-ripe fruit before visible damage appears. Frequent harvesting — every two days during peak season — and immediate refrigeration after picking is the most practical control available to home growers.
Verticillium wilt causes plants to collapse suddenly during summer, with leaves wilting and browning from the outside in. There’s no treatment; the only fix is removing affected plants and rotating the bed to a fresh site. This is exactly why the rotation rule from the site selection section matters. If your plants are drooping and you’re unsure whether the cause is wilt, drought, overwatering, or crown rot, our strawberry drooping guide walks through all five causes with a step-by-step diagnostic.
Harvesting
Strawberries don’t ripen after picking [1]. Unlike tomatoes or apples, there’s no such thing as leaving a pale strawberry on the windowsill to sweeten up — what you pick is what you get. Harvest only when the berry is fully red all the way to the calyx (the green leafy top). Pale shoulders or white tips mean it’s not ready.
During peak season, harvest every two to three days. Ripe fruit left on the plant deteriorates quickly and provides an entry point for mould and insects. Harvest in the morning when the fruit is cool. Pinch the stem rather than pulling the berry — strawberries bruise easily and broken skin cuts shelf life to hours. Store refrigerated and unwashed, and rinse just before eating.
Expect roughly 1 to 1.5 pounds of fruit per June-bearing plant at peak maturity in year two or three. First-year plants produce less, which is another reason the bloom-pinching step matters so much.
The flavour window on a truly ripe, home-grown strawberry is about 24 hours. Supermarket varieties are bred for firmness and shelf life — a very different set of priorities from flavour. That gap is really the entire reason to grow your own.
Overwintering Your Strawberry Bed
In most temperate climates, strawberry plants need winter protection to survive hard freezes. The crown is moderately hardy, but repeated freeze-thaw cycles that heave roots out of the soil are the main danger.
Wait until plants have experienced two to three frosts and temperatures are consistently staying below 40°F (4°C) before mulching [1]. Mulching too early — before the plants have hardened off naturally — can trap moisture around warm crowns and encourage the very rot you’re trying to prevent.
Apply 4 to 6 inches of weed-free straw over the plants [1]. Straw is the traditional choice because it’s loose enough to allow air circulation while still providing good insulation. Pine needles work equally well, particularly in acidic soils. Avoid using leaves — they mat down, trap moisture, and create conditions for crown rot.
In spring, remove most of the mulch as new growth begins to emerge. Retain a thin layer at soil level through the summer to suppress weeds, retain moisture, and keep developing fruit off the ground — a small effort that noticeably reduces slug and mould problems.
Key Takeaways
A strawberry bed is a long-term investment that compounds over time. Year two and three are almost always better than year one — assuming you lay the groundwork correctly from the start.
The decisions that matter most:
- Choose the right type for your goals — June-bearing for bulk harvests, day-neutral for containers and continuous picking
- Nail the crown depth at planting — it’s the single most common cause of first-year failures
- Fertilise in autumn, not spring — nitrogen absorbed after harvest builds next year’s flowers
- Renovate immediately after harvest — the canopy that forms in late summer sets the flower bud count for next year
- Use runners strategically — free replacement plants from year three onwards
