Organic fertilizers for healthy strawberry enjoyment
Healthy fruit and vegetables from the hobby garden result primarily from the conscious use of compost for the supply of nutrients. The eternal cycle of materials in nature is used sensibly for the production of purely organic fertilizer. If there is no possibility of creating a compost heap, these alternatives are possible:
- Horse manure
- Plant manure
- Can my dog eat strawberries?
- How do strawberries benefit from bark mulch?
- Which strawberries have what it takes to be a ground cover?
Mineral berry fertilizer scores points over purely organic preparations with a quick effect; However, there is still uncertainty as to which ingredients end up in the strawberries.
The perfect start with the right fertilizer
Experience in the cultivation of strawberries has shown that the plants do not or hardly grow in freshly tilled soil. As a result, the start fertilization is applied one to two months before the planting date. This process has proven itself:
- Dig the ground two spades deep
- Sieve out stones, roots and weeds
- Mix the excavation with compost, horn shavings (€ 6.39 at Amazon *) or other organic fertilizer
- alternatively work a mineral berry fertilizer with 60-80 grams per square meter into the soil
This approach also applies to starting fertilization in the tub or flower box. The potting soil enriched with compost from the specialist trade should have at least 14 days to sit down. Then plant the young strawberries without working the substrate.
Fertilize annual strawberries in a balanced way
Although the hardy strawberry plants are suitable for perennial cultivation, many hobby gardeners opt for annual cultivation. Regardless of when the start fertilization took place, this chronology applies to the further nutrient supply:
- Before flowering, fertilize with 5 liters of compost or 60-80 grams of berry fertilizer per square meter
- in lean soil, if necessary, fertilize again in halved dosage before the fruit ripens
In order to avoid over-fertilization with all negative consequences, experienced hobby gardeners refrain from fertilizing before the fruit ripens in case of doubt. This is especially true with regard to the use of concentrated, mineral berry fertilizers. A professional soil analysis provides information about the actual nutrient requirements.
When are perennial strawberry plants fertilized?
The optimal date for the main fertilization of perennial strawberry varieties is immediately after the harvest in autumn. Ideally, apply 5 liters of sifted compost or an alternative organic fertilizer per square meter of bed area. The soil organisms have sufficient time until next spring to prepare the nutrients for the strawberry plants to take up. If you prefer mineral berry fertilizers, the same dosage applies as at the start.
In the following season, the nutrient supply runs according to the same schedule as for the annual strawberry varieties.
Climbing strawberries and other varieties that are wintered in a planter receive additional nutrients throughout the season. In this case, give liquid compost, worm tea or a suitable liquid fertilizer for berries every 2 weeks. It is important to note that you do not pour this fertilizer on dried out substrate.
