Planting, Growing, and Harvesting Strawberries
When to Plant Strawberries
- Plan to plant as soon as the ground can be worked in the spring. See your local frost dates.
- Establish new plants each year to keep berry quality high each season. Strawberry plants will produce runners (daughter plants) that will root and grow into new strawberry plants.
- Buy disease-resistant plants from a reputable nursery, of a variety recommended in your area. Consult with the nursery you buy them from or with your state Cooperative Extension service for locally recommended varieties.
Choosing and Preparing a Planting Site
- Strawberry plants require 6-10 hours a day of direct sunlight, so choose your planting site accordingly.
- Strawberries are tolerant of different soil types, although they prefer loamy soil that drains well. Ideally, begin working in aged manure or compost a couple months before planting. If you have clay soil, generally mix in 4 inches or more of compost, and rake the clay soil into raised mounds to further improve drainage. If your soil is sandy, simply cultivate lightly to remove weeds, and mix in a 1-inch layer of rich compost or rotted manure.
- Soil pH should be between 5.5 and 7. If necessary, amend your soil in advance of planting. If soils in your area are naturally alkaline, it is best to grow strawberries in half-barrels or other large containers filled with compost-enriched potting soil.
- The planting site must be well-drained. Raised beds are a particularly good option for strawberry plants.
- Practice crop rotation for the most success. Unless you plan to amend your soil each year, do not plant in a site that recently had strawberries, tomatoes, peppers, or eggplant.
How to Plant Strawberries
- Provide adequate space for sprawling. Set plants out 18 inches (1-1/2 feet) apart to leave room for runners and leave 4 feet between rows. Strawberries are sprawling plants. Seedlings will send out runners, which in turn will send out their own runners.
- Make planting holes deep and wide enough to accommodate the entire root system without bending it. However, donāt plant too deep! The roots should be covered, but the crown should be right at the soil surface. It is very important that you do NOT bury the crown (central growing bud) of the plant or it could rot. The leaves, flowers, and fruit must be exposed to light and fresh air.
- To settle their roots into the soil, water plants well at the time of planting.
- It is also possible to grow strawberries from last year’s runners. See this video to find out how.
How to Grow Strawberries
- Keep strawberry beds mulched to reduce water needs and weed invasion. Any type of mulchāfrom black plastic to pine straw to shredded leavesāwill keep the soil moist and the plants clean. Read more about mulching.
- Be diligent about weeding. Weed by hand, especially in the first months after planting.
- Moisture is incredibly important to strawberries due to their shallow roots. Water adequately, about one inch per square foot per week. Strawberry plants need a lot of water when the runners and flowers are developing and again in the late summer, when the plants are fully mature and gearing up for winter dormancy.
- Fertilize with all-purpose granules for strong growth. In warm weather, berries ripen about 30 days after blossoms are fertilized.
- In the first year, pick off blossoms to discourage strawberry plants from fruiting. If not allowed to bear fruit, they will spend their food reserves on developing healthy roots instead, which is a good thing. The yields will be much greater in the second year.
- Eliminate runner plants as needed. First and second generations produce higher yields. Try to keep daughter plants spaced about 10 inches apart.
- Row covers are a good option for protecting blossoms and fruit from birds.
Winter Care of Strawberries
Strawberry plants are perennial. They are naturally cold hardy and will survive mildly freezing temperatures. So, if your area has mild winters, little care is needed.
In regions where the temperature regularly drops into the low twenties (Fahrenheit), strawberries will be in their dormant stage. It’s best to provide some winter protection:
- When the growing season is over, mow or cut foliage down to one inch. This can be done after the first couple of frosts, or when air temps reach 20Ā°F (-6Ā°C).
- Mulch plants about 4 inches deep with straw, pine needles, or other organic material.
- In even colder regions, more insulating mulch should be added.
- Natural precipitation should appropriately maintain sufficient soil moisture.
- Remove mulch in early spring, after the danger of frost has passed.
How to Harvest Strawberries
- Fruit is typically ready for harvesting 4-6 weeks after blossoming.
- Harvest only fully red (ripe) berries, and pick every three days.
- Cut by the stem; do not pull the berry or you could damage the plant.
- For June-bearer strawberries, the harvest will last up to 3 weeks. You should have an abundance of berries, depending on the variety.
How to Store Strawberries
- Store unwashed berries in the refrigerator for 3ā5 days.
- Strawberries can be frozen whole for about 2 months.

It is funny that altho I have a compulsion to put things in rows and keep everything to a minimum, I don't plant that way. Why? Because nature doesn't plant that way. I have waist high planters and 16 inch pots that hold everything. My strawberries had the last three months in shade because I hadn't gotten the lay of the land in my front yard. They will probably be sent to the back deck soon as the old tree in the front has decided to spread more this year. They are crowded, no mulch, and producing like they are very happy. I don't keep the runners cause they are not as vigorous as the mother plants and over time will revert to the original berry species. But they do look pretty hanging over the side of the pot. It's funny how all the sites say the same thing, I have never paid attention and currently have enough strawberries to make a pie with rhubarb I found at the local market... these are day neutral...good times
i grow hydroponically everything from tomatoes to lettuce in perlite with nutrients can you grow strawberry's
in perlite
Can I grow the runners indoors once I've cut them off? If so, how? Hydroponics or planted? They don't have time to establish roots outdoors and I hate to waste the 20 baby plants. ALL have large nodes for roots.
My strawberry bed is over ten years old,
old plants are replaced by new runners and produce nice size fruit,
however two years ago I started noticing new strawberry plants but they're like wild ones.
They have tiny little berries and have spread all over.
I've tried pulling out those runners but can't get them all.
I'm afraid they will choke out my real plants.
How do I rid my garden of these wild ones?
Mulch with sand n compost covering the undesirable plants and leaving the others to thrive.
