Cultivating an abundant yield annually necessitates proper care and fall fertilization of the plant.
Raspberries are a popular fruit in many gardens, but ensuring they grow well can sometimes be a challenge, especially when the soil is depleted. Here are some tips for fertilizing and pruning raspberries to promote healthy growth and high yields.
If the soil is not rich in nutrients, applying a combination of ammonium nitrate, superphosphate, and potassium salt can help improve raspberry growth. In the spring, apply 1 teaspoon of ammonium nitrate per square meter or 1 tablespoon per linear meter, 3 teaspoons of superphosphate per square meter or 2.5 tablespoons per linear meter, and 1 tablespoon of potassium salt per square meter or 1.5 tablespoons per linear meter.
In September, if raspberries are already growing on your plot, you can apply superphosphate (1-1.5 tablespoons per square meter or 2-3 tablespoons per linear meter) and potassium salt (1-2 teaspoons per square meter or 3-4 teaspoons per linear meter). This will help prepare the raspberry plants for winter and promote the formation of new canes.
Organic fertilizers like manure or compost are also effective, and combining all three components - organic matter, phosphorus, and potassium - increases the yield almost one and a half times compared to areas where no fertilizers were applied. If the soil is poor, it's best to use organic fertilizers in September. If the soil is rich in nutrients, mineral fertilizers like superphosphate and potassium can be used instead.
When it comes to pruning, the optimal time is September. Prune raspberries from September to November to remove weak, diseased, or dead canes, and to encourage new growth. If raspberries are grown as a solid mass, dissolve the fertilizers in water and water the plants after pruning. If they are grown in rows, spread the fertilizers in the rows and dig the soil to a depth of a spade after pruning.
It's important to remember that all fertilizers should only be applied to well-moistened soil. Water the raspberry plants before applying fertilizers if the soil is dry. Organic fertilizers should be applied annually, at a rate of half a bucket per square meter or one bucket per linear meter. If this is not possible, they can be applied once a year, but in this case, the dose of mineral fertilizers should be doubled.
In October, you can apply partially rotted manure under the raspberries or compost or humus. A combination of organic and mineral fertilizers yields the best results. It's also important to remember that all fertilizers should only be applied to well-moistened soil, as stated earlier in the article.
Research has shown that a combination of organic and mineral fertilizers yields the best results for raspberries. Experts recommend fertilizing strawberries in spring primarily with nitrogen (N), phosphorus (P), and potassium (K) to promote healthy growth, flowering, and fruit set; the fertilizer should be applied mixed with the topsoil and watered in, with typical amounts around 30-40 g per square meter at the start of vegetation.
If you're planting new raspberry plants, prepare planting holes 50 cm wide and 40 cm deep, filling them with a mixture of fertile soil and compost in a 1:1 ratio, and adding a tablespoon of superphosphate. This will give your new raspberry plants a great start.
By following these tips, you can ensure that your raspberries grow well and yield a bountiful harvest. Happy gardening!
