If you are looking for ways to make your raspberries produce more fruit, there are a number of things that you can do to increase their yield.
Pruning, feeding, and planting them early are all important.
You can also buy some compost or apply it to the soil outside.
The timing of feeding is also crucial. If you feed them more frequently, you can expect larger berries.
This is due to the fact that raspberries can tolerate very little water and still thrive.

Raspberry plants grow and bear fruit for two summers. Their canes start out as primocanes grow vegetatively during the first year and then produce fruit. After fruiting, these canes die.
The new canes form next year and the process begins again. Pruning raspberry plants to produce more fruit is a necessary part of raspberry care. During the winter, prune out the old canes to encourage growth.
Summer-bearing raspberries are generally pruned in early spring or fall. Some growers choose to prune during the fall because it reduces winter injury.
To prepare for winter, prune plants to reduce the number of canes and narrow the rows. Remove old flowers and clusters from the canes at ground level. Prune the remaining canes to leave at least 6 inches between them.
Avoid removing old, spindly sprouts.
After pruning, raspberry plants should be trellised to maximize sunlight. To trellis the plant, build a ‘T’-shaped trellis out of two t-shaped boards.
Each trellis should be about two feet wide, allowing the raspberries to climb over the trellis. This method will encourage fruit production by ensuring that the entire stalk receives plenty of sunlight.
Raspberry plants require fertilizer to flourish. To get bigger berries, you must feed your raspberries once they have begun to bloom.
You can feed them with a canola and fish meal mixture. Fertilize the soil twice a year. Before blossoming, the plants don’t need as much nitrogen, so they can tolerate less fertilizer. If you are fed with the right type of fertilizer, you can expect to see more fruit in a shorter period of time.
The most essential nutrient for raspberries is nitrogen. In sandy soil, raspberries require a higher level of nitrogen than those in clay.
A good general rule of thumb is to use three to five pounds of urea or ammonium sulfate per 100-foot row feet. In total, you should apply 150-275 pounds of fertilizer per acre. You can also add other nutrients to the soil if soil tests show it needs them or you notice any symptoms of deficiency.
While feeding raspberries can help your plant to produce more fruit, they need special care to produce more flowers. Everbearing raspberries continue producing fruit until the first frost.
You can use fertilizers in early spring or late summer to promote a healthy plant. To get more fruit from your raspberries, you should feed them every couple of weeks. The best time to feed them is when they’re just starting to grow.
Raspberry plants can be planted in a row for easier harvest and less risk of disease. They can be replanted to produce more fruit as well.
The good thing about raspberries is that they are self-pollinating. If you want to increase their fruit production, consider pollinating your plants. Using a pollinator will improve the quality of your fruit.
Here are some tips to help you plant early.
Always plant raspberries in the early spring as the soil is still warm and workable. Planting early prevents the raspberries from fruiting in the early summer, which makes picking easier and ensures you get a bumper crop.
Plant raspberries at least 6 weeks before the first frost to give them plenty of time to grow. Also, keep in mind that raspberries like full sun, but part shade may be better if you live in a hotter climate.
The plants grow in cycles of two years. Summer fruiting raspberries produce berries on the canes of last year’s growth.
Autumn fruiting raspberry plants have canes that flower and bear fruit in the same year, and should be spaced at least 15 cm apart. The summer-fruiting variety should be pruned to the soil level, as the new canes will produce more fruit.
One of the most important things to remember about growing raspberries is to water them regularly. Natural rainfall is usually sufficient but watering them will help keep them healthy and productive.
Mulching your plants will help retain the moisture they need and provide a small but constant supply of nutrients.
Make sure to remove old and damaged branches from the raspberry plants after harvesting. Lastly, prune the plants to reduce the risk of disease. Pruning also helps increase the amount of fruit a plant produces.
Raspberry plants are prone to diseases. While the summer variety has a perennial root system, the fall cultivar produces fruit on wood that is one to two years old. Ideally, the plants will produce both floricanes and primocanes during the year.
This way, the plants will survive Minnesota’s cold winters better. For optimal fruit production, prune the raspberries once a week and water them as needed.
To increase the amount of fruit a raspberry bush can produce, you can mulch the soil around it. Ensure that the mulch is well-rotted organic matter and does not touch the stems of the plant.
A mulch of around 10cm/4in is beneficial. Mulching is best done in the third week of March, after feeding your plants. Make sure to mulch your plants with 2-4 inches of organic mulch to retain moisture and prevent soil crusting.
Pruning twice a year
To get more fruit from your raspberry bush, prune it twice a year. Summer-bearing raspberry plants produce fruit on their floricanes, which have to grow for two years before they bear fruit.
In late March, you can prune away the spent floricanes and thin out any that are too many. During late winter, you can thin out the floricanes as they start to sprout new shoots.
It’s better to prune your summer-bearing raspberry plants than those that bear fruit in the winter. Winter-bearing raspberries should be pruned when their new canes begin to grow crowded and diseased.
This helps prevent diseases from spreading. While diseases are often prevented by buying certified plants, some can still occur. To reduce your risk of contracting these diseases, prune the plant as early as possible.
When pruning raspberry plants, make sure you prune the lower canes in spring and again in early April.
Pruning should remove any weak or diseased canes and leave only the strongest ones. Remember, that the second year’s canes will die shortly after they produce fruit. This will promote growth. Pruning raspberries will give you more fruit. Your raspberries will thank you!
If you grow black raspberries, don’t trellis them. They can be grown in a hill system. However, if you’re a beginner, you can treat them like an erect blackberry and prune them in June.
Pinching back the shoots will stop terminal growth and three to five buds will develop. The canes will then become self-supporting.
After winter pruning, you can prune the canes to remove those with fruit and keep the remaining canes with two to six buds per cane. You can also remove the small canes if you don’t want them to produce fruit.
Planting in a sunny position
If you’re growing raspberries, you’ve probably wondered if you should plant them in a sunny spot.
But there’s more to planting your fruit-producing plants than that. For example, if you’re planting them in a shady spot, you risk having your side-branches break in strong winds. Here are a few tips for keeping your plants healthy and productive in the long run.
First, make sure your plants get indirect light. Ideally, you’ll need a 70-degree heat mat to make them sprout roots faster. After 6 to 8 weeks, you should move the plants to more nutrient-rich soil.
In addition, you should consider layering, a tried and true method for propagating many plants. Use a dormant branch in early spring and a fully-grown one in late summer.
As for the soil, raspberries do best in a sunny position, although they can tolerate partial shade. You can improve the soil by incorporating compost or aged manure before planting your plants.
This fertilizer should be added to the soil a couple of weeks before planting your raspberry plants to allow the organic matter to fully break down and settle.
Adding a soaking to the roots before planting is also helpful, especially if the raspberries are bare-root. In most cases, you do not need to water the roots once planted.
If you are growing your raspberries in a hedge or row, you’ll want to space them about a foot apart and tamped down the soil to prevent weeds and other weeds from growing in the soil.
Then, plant them in a sunny spot and don’t forget to feed them regularly to encourage lots of fruit.
And, don’t forget to water them, especially during the hot summer months.
