Feed Your Strawberries – Most container plants benefit from some supplemental feeding. Feed your strawberries every three to four weeks with a balanced liquid fertilizer, Make sure to apply a balanced fertilizer in the fall as well, as the plants will begin forming perennating buds within the crown that will become next year’s flowers and fruit.

What is the best fertilizer for container strawberries?
Can you use tomato fertilizer on strawberries? – A tomato fertilizer is rich in potassium and that makes it perfectly suitable for using on strawberry plants. Such a feed on strawberry plants that are growing in pots or containers every week or two from early spring onwards will boost flowering and the setting of fruit.
How much nitrogen do strawberries need?
How Can You Make Sure Your Strawberry Plants Get All the Nutrients They Need? – Fertilizing strawberry plants doesn’t have to be complicated. You just need to use different approaches for different planting methods. If you are a home gardener with a small strawberry patch, most of the nutrients your strawberry plants will use need to be put into the soil before you plant them.
- It is always a good idea to incorporate about 3 inches (7 or 8 cm) of well-aged compost into the top 6 inches of the soil in your strawberry bed.
- This compost will both provide nitrogen, phosphorus, and potassium to your strawberry plants and provide a growing medium for the fungi that bring other nutrients and water to strawberry plant roots.
You can provide your strawberry plants with foliar feedings of higher-nitrogen fertilizers (always diluted according to label directions) before they blossom and seaweed sprays for micronutrients as they begin to set fruit. If you have a larger strawberry patch, and you only keep your plants through one harvest (which means you start with strawberry plants in pots and you don’t use bare root strawberry plants), you can consider chemical fertilizers.
The most important consideration for home growers is not to over-fertilize. Strawberry plants need about 75 pounds of nitrogen per acre. That is about a pound and a half of nitrogen for a 1000 square footbed, but chemical fertilizer is not 100% nitrogen. It’s more likely to be 15% nitrogen. (The label will read 15 and then some other numbers, the first number telling you the percent nitrogen.) You need about 1-1/2 pounds divided by 15% or 10 pounds of fertilizer for every 1000 square feet of the strawberry patch.
Apply nitrogen fertilizer early in the growing season by scattering pellets evenly across your strawberry patch and be sure to water in. It’s great to give your non-organic strawberry plants organic foliar feedings for nitrogen boosts as the growing season goes on and trace nutrients for berry production.
What is the best natural feed for strawberry plants?
Feeding strawberries naturally – Natural fertilisers such as leaf humus or bark compost encourage soil life and improve soil structure over time. They have proven to be particularly effective for feeding strawberries in autumn. Natural slow-release fertilisers or horn manure are also suitable for feeding strawberries.
- Using tomato feed for strawberries is also an option.
- Our Plantura Tomato Food, which supplies tomatoes ( Solanum lycopersicum ) and potatoes ( Solanum tuberosum ) with all the nutrients they need, is a great choice for strawberries too.
- It consists primarily of organic plant matter that is slowly decomposed by soil microorganisms.
Its high potassium and phosphorus content helps strawberry plants to flower and produce fruit. Its nitrogen content encourages plant growth and leaf formation. Nutrients such as potassium and phosphorus help strawberries grow and flower To help you supply your strawberries with the ideal amount of nutrients, we have prepared a fertilisation guide for you to follow: Summary: When and how much to feed your strawberries
- Before planting: work 60 – 110 g/m² (5 – 9 tablespoons) of our Plantura Tomato Food into the topsoil
- Water the soil and plants to activate the fertiliser granules
- In the autumn following the harvest and in spring, give each plant 40 – 70 g of fertiliser (3 – 5 heaped tablespoons)
What is the best soil prep for strawberries?
Strawberries are one of the most popular small fruits to grow in the home garden. You will have delicious fruit the first season if you keep a few things in mind. There are two types of strawberries: day-neutral varieties, also called ever bearers, and short-day types.
- Ever-bearing plants are not affected by day length and have their highest production from spring through fall.
- Short-day types produce from fall through early spring when days are shorter.
- In our area, ever bearers are generally considered synonymous with day neutrals.
- Your strawberry plants will need at least eight hours of full sun each day to produce well.
Strawberries grow best in loamy or sandy soils. Before planting, prepare the soil by incorporating two to three inches of compost or other organic matter to a depth of at least 12 inches. Organic matter improves nutrient availability as well as the soil’s structure and water-holding capacity.
- Dig in some balanced fertilizer as well.
- Strawberries may still need to be fed several times during the growing season.
- Poor vigor or light green leaves tell you that it’s time to fertilize.
- Heavy clay soil hampers strawberry growth and vigor and encourages disease, but you can succeed with clay soil if it is well drained.
If possible, plant strawberries in raised beds to improve soil drainage and aeration. When planting, remove any dead leaves, spread the roots out in the planting hole, and firm the soil around the plant. The crown of the plant — the area between the roots and the leaf stems — should be even with or slightly above ground level.
Water the transplants well. Strawberry plants have shallow roots and need to be kept moist during the growing season. Use drip irrigation to keep moisture away from the fruit, minimizing fruit rot. Strawberries don’t compete well with weeds, so be a vigilant weeder to extend the life of your beds. Think about your strawberry bed as a temporary structure.
Relocate plants after three to five years to prevent buildup of soil-borne pathogens. Avoid planting them in areas where you have recently grown other members of the Solanaceae family, such as peppers, tomatoes, potatoes, eggplant and okra. They are all subject to the same soil-borne diseases.
- Napa County Master Gardeners recently completed a year-long field trial of three markedly different strawberry varieties.
- We grew two day-neutral varieties, Albion and Quinault, and one short-day variety, Sequoia.
- Trial participants planted bare-root seedlings in January.
- Some gardeners planted in containers, which work well because of the plants’ small root systems.
Following common practice, we removed runners the first year to strengthen the mother plants. Some gardeners also removed the first flush of blossoms and consequently harvested a meager amount of Sequoia berries, if any. Most of us used straw mulch to retain soil moisture and keep fruit off the ground, away from earwigs, sow bugs, snails and slugs.
Birds pecking at ripe fruit were among the most annoying pests; some gardeners used netting to control them. Fruit production varied. The Sequoia plants produced some huge, sweet berries but finished production before hot weather began, leaving us with the impression that its growing season was too short.
The Quinault plants yielded smaller, very soft fruit that needed to be eaten almost immediately. A few growers complained about having to throw away so many Quinault berries because they were too soft. Albion berries were by far the best producers, yielding large, sweet, conical fruit on upright stems. Our group kept yield records through Oct.31. However, several gardeners, as well as their children and grandchildren, succumbed to temptation and ate some of the juicy crop before it had a chance to be weighed. Consequently, our results are not rigorously scientific.
Roughly speaking, Albion berries accounted for 67 percent of the total yield, Quinault berries 25 percent and Sequoia berries 8 percent. Most of the participants intend to keep their plants going for another year.
