If you want a quick harvest of berries soon, it’s best to get cuttings from healthy plants or buy fresh rootstock from a local farmer in your area. Raspberry plants are hardy perennial and easily propagated by seeds. Raspberries prefer sunny, well-drained soil; mature Raspberry plants will grow between 36 and 60 inches in height, with a spread of 24 to 36 inches. Raspberry will bear fruit in its second growing season when planted from seeds.

How to grow Raspberries from seed to harvest

How long does Raspberry take to grow from seed? 

  • It takes patience to grow Raspberry from seeds. From germination to fruit, it takes 18 months. Raspberry needs only one plant for flowering and production.        
  • For the summer-bearing plants, it takes two years for each cane to bear fruit. Individual canes grow, leave only in the first year, produce fruit in the second year, and then die. You can cut second-year canes and take them back to the ground when you have cut all the fruits.
  • You should know that Raspberry is not developed true to seeds, and all your seeds will be different from your parents in the same way that children differ from their parents. Only Raspberry breeders produce plants from seeds. 

How long do Raspberry seeds take to germinate? 

  • Growing Raspberry from seeds is easy and is much cheaper than buying a Raspberry cane in the nursery or the center of the garden, though it takes a bit longer. Starting Raspberry with seeds will give you a lot of plants, which means you will have an abundant supply of fresh Raspberry at the time of harvest.  
  • Your Raspberry plant will need a lot of sunshine and warmth. Be sure to keep it in a sunny place, where it will get at least 6 hours of sunlight. Fill the seed starter tray with sterile potting soil in early autumn. Press one to two Raspberry seeds 1/4 inch down into the soil of each cell. Gently tap the soil down on the seeds to remove the air pockets. 
  • Lightly mist the soil using a spray bottle filled with water. Keep the soil moist during the process of germination. The seeds will start sprouting within three months.
  • Keep the soil moist and provide proper light to the Raspberry plants as they grow. Transplant Raspberry plants outside in the spring as soon as the soil is workable.
  • The growing season for Raspberry begins from early to mid-spring, once the temperature reaches at least 16°C. It will take about four to six weeks to germinate, and you can expect the plant to produce fruit 16 to 18 months after the planting. 

Do Raspberry seeds need to be dry before planting?

  • Raspberry fruit seeds can be harvested by placing several good-quality ripe Raspberries in the sieve, rubbing them with pulp, and then thoroughly washing the seeds to remove all traces of pulp. The wet seeds are then placed on a paper towel in the sun to dry.
  • Store indoors, such as in a pantry or garage, in a dim, cool space. You should keep the seeds moist by spraying with a spray bottle as needed. Once the temperature reaches above 16°C, place the Raspberry pot outdoors. After 3 to 6 weeks, the seeds should start germinating. 
  • Seeds and seedlings should be kept a little moist, not too wet; otherwise, they will rot. Plants should not be transplanted directly into the outside garden but rather hardened off or transferred to a cold frame.

What is the best month to plant Raspberries?

  • The best time to plant Raspberries is early spring. Choose a plantation site that is in full sun. The plants will grow in partial shade but will not produce as much fruit. Raspberries prefer rich, well-drained soil. 
  • Mild days in late autumn or early winter are a good time to plant Raspberry canes. Choose an open, sunny place. The soil should be free draining, adding a lot of well-rotted garden compost or manure.
  • The space canes are 45 centimeters apart, with 1.8 meters between the rows. Just cover the roots with about 5 centimeters of soil. Place any white buds at the base of the stem on the soil’s surface. Firm soil and water wells around each cane. Canes are usually pruned in advance, ready to be planted. 

How many Raspberries do you get from one plant?

  • The average yield per plant is 1 to 2 quarts of Raspberries. Raspberry is one of the most popular berries, and a Raspberry bush can produce several hundred berries per season. When deciding whether to devote some space in your garden to a Raspberry plant, the main consideration is how much it produces each year.
  • Fruits produced from the same Raspberry plant are about 7 kg but vary significantly with the varieties grown. Summer fruiting varieties generally produce higher yields than autumn fruiting varieties.
  • For people unfamiliar with Raspberry, there are two main types, summer fruit, and autumn fruit. The main difference between these varieties is the age of the cane on which the fruit is made. This, in turn, affects the time of year the fruit is harvested.

How do I make more Raspberries?

To help your Raspberry plants thrive and produce a bumper crop each year, make sure you choose the best variety for you, plant them in a good place with enough sunshine, and prune them back in the right season, so they continue to bear fruit year after year.

Do Raspberries need full sun?

  • Raspberry bushes grow best throughout the sun for at least 6 to 8 hours in rich, well-drained soil. While fruit plants need the sun to ripe the fruit, too much direct sunlight on the fruit during low humidity can cause the fruit to burn. Sunburn on fruit crops appears as large white or brown blotches on the fruit’s side that are exposed directly to the sun.
  • Raspberry needs full sun for excellent fruit production and overall plant health. Sunlight is necessary for the occurring photosynthesis, which converts sunlight, water, and carbon dioxide into sugar, composed of delicious berries. When Raspberry does not get enough sunlight, the plants will fail to produce fruit. Furthermore, sunlight minimizes the chances of fungal pathogens gaining a foothold.

Why is my Raspberry plant not fruiting?

  • The common reason for no fruit on Raspberry plants is improper pruning, but other problems can also be a problem. Improper growing conditions, pests, or diseases cause plants that fail to reach full size or produce fruit. Raspberries grow best in raised beds filled with rich, fertile soil.   
  • Raspberry grows best in raised beds filled with rich, fertile soil. They require at least 6 hours of direct sunlight per day and 1 inch of rain per week. If you’re meeting these needs and pruning correctly yet not producing Raspberry plants, it’s time to look for hints that indicate common Raspberry pests or diseases.

Can you grow Raspberries in pots?

  • You can grow beautiful, juicy Raspberry completely indoors. Growing and maintaining Raspberry plants indoors may seem difficult, but don’t let the idea overwhelm you. Raspberry plants are relatively low-maintenance, and growing them indoors is not much more than planting them in the garden.
  • Growing Raspberry in containers is a great option for people with poor garden soil, shady backyards, or very little garden space. The great thing about container gardening with Raspberry is that you can place the pots in any sunny corner without worrying about the soil.
  • It’s easier to grow berries in pots when you choose the right container, variety, and location. In addition, growing in containers gives you more control over soil conditions, moisture levels, lighting, space, and winter protection.
  • Raspberry, especially small varieties, can grow well in large pots in sunny, shelter spaces. Choose a container at least 38 centimeters wide and fill 80% with multipurpose compost and 20% loam-based potting compost, to add weight for stability.

Do Raspberry seeds need to be stratified?

  • If you’ve collected your Raspberry seeds, they need a cold stratification period to break down dormancy. It naturally occurs outdoors if you seed it in the garden in the fall or winter. To start Raspberry seeds indoors, you should follow the cold stratification process before planting. Raspberry seeds usually require a period of cold temperature to germinate successfully. This prevents them from germinating at the wrong time of year.  
  • Raspberry seeds need a cold stratification to germinate, which means exposure to cold temperatures for an extended period. Some farmers prefer to plant Raspberry directly from seeds in the garden in late autumn. Others choose to grow Raspberry from seeds indoors in late winter or early spring.

Can I cut Raspberries down every year?

  • Growing Raspberry is one of the best ways to enjoy your delicious fruits year after year. However, you must practice annual harvesting Raspberry pruning to get the most out of your crops.
  • Once your Raspberry plants have grown enough, pruning in early spring is intended, just as new growth emerges. Prune back the young canes until they are about 4 to 5 feet tall.
  • When the canes are about 30 inches long, just cut off the stem growth from the top 2 to 3 inches. This will encourage more side shoots and fruit buds and keep the canes at a more workable height. In late winter, prune the canes as you would for red Raspberries.
  • If you don’t prune your Raspberry bushes, they will continue to grow and produce fruit, but as a result of overgrowing, the canes compete for sunlight and nutrients, which can cause the bottom of the leaves and buds to die as they prevent sunlight from reaching the flowering canes.
  • Remove the small, weak canes, leaving only four or five of the largest, most vigorous canes per clump or plant. Cut lateral branches up to 12 inches long for black and 18 inches for purple Raspberry.

Do you need 2 Raspberry bushes to produce fruit?

  • Combining both berries would be an ideal way to maximize crop duration. You need one bush to produce fruit because all Raspberries are self-fertile. They are best pollinated by bees and will start producing fruit a year after planting.
  • Raspberry is one of the most popular berries, and a Raspberry shrub can produce several hundred berries per season. Learn how to plant and grow Raspberries, and the important thing is how to prune Raspberries after picking plants to encourage them to grow new fruiting stems.

Do Raspberries need a trellis?

  • Black and purple Raspberries don’t require a trellis, although you may want to use the simple trellis described for primocane fruiting varieties. 
  • Trellis can support Red, black and purple Raspberries. This is especially important when plants are loaded with fruits. Fruits on trellised plants are clean and easy to pick. 
  • Raspberry bushes need strong support to grow in an orderly manner. The easiest way is to set up a post and wire system. Make a T-post with two crossbars, one at the top and one in the middle of the post. Place a T-post with a row of Raspberries every 5 to 8 feet.
  • Raspberry is usually placed in rows and is supported by a system of posts and horizontal wires. But if you don’t have room for it, you can grow a couple of plants with the help of just one post or a plant in a container with the help of bamboo sticks. You should provide support at the time of plantation. 

Do Raspberries need fertilizer?

  • The fertilizer of the Raspberry plant should be heavy in nitrogen, although a balanced variety is often preferred. The best fertilizer for Raspberry bushes is 10-10-10 fertilizer or actual nitrogen at a rate of 1.8 to 2.3 kg.
  • They mostly thrive on well-drained soil, especially neutral to acid. Before planting on shallow, dry, or chalky soil, it is essential to add well-rotted manure or good garden compost to the soil. 
  • Raspberry requires a 2 to 3-inch layer of mulch. Good mulch for use in a home garden includes leaves, lawn clippings, and wood chips or shavings, as they are usually free of weeds.
  • Fertilizing is an excellent way to replenish nutrients in your soil, including most nitrogen. Nitrogen stimulates green leafy growth and stems, which ultimately feed and support future fruits. Like most berry bushes, Raspberries produce the most fruit when things are good. However, they will dry up and produce poor crops if they do not have nutrients. All the elements are necessary for the Raspberry plant; however, nitrogen plays an important role.

How tall should Raspberry canes be?

  • Generally, most Raspberry plants grow naturally within a range of 4 to 5 feet, both long and wide. Raspberry plants are at a distance of 3 to 5 feet, with a distance of 6 to 8 feet between rows.
  • However, pruning is an essential aspect of growing Raspberries, and pruning techniques can vary depending on the type of Raspberry. You can grow freestanding plants or use support and prune them to maintain size and shape.

How do you winterize Raspberries?

  • Fold the burlap over the canes and secure it with twine. Remove the trellised Raspberry canes with their support. Place the canes gently on the ground and cover them with 3 to 4 inches of straw.
  • Continue to water Raspberries long after the plants have stopped producing fruit, and do not stop watering until the first frost. This extended water prevents over-drying during winter and helps harden plants and prepare them for cold. While cutting the canes, cut them to the surface of the soil. If these are new plants that have not yet experienced winter, bury the rest of the Raspberry canes, as these plants are more sensitive to the winter cold. 

How do you make Raspberries bloom?

  • To produce flowers and fruits, Raspberries must be pruned properly. Red Raspberry must be pruned twice a year in the summer; in early April, prune out all weak canes. Also, cut canes more than 5 feet long until they become about 4 1/2 feet high. Remove all the fruit canes after harvesting. 
  • Flowers are expected to form in July for most places. The first year’s harvest will be small. During the second summer of growth, the flowers will form on the lower parts of the canes that fruited last year.

Do Raspberry plants need a lot of water?

  • Water Raspberry plants during the day. Give them about 1 to 2 inches per week during the growing season and up to 4 inches per week during harvest. Plants are rather shallow roots, so moisture needs to be at the surface. 
  • Raspberry requires a lot of water from spring to post-harvest. Since the root system is in the top two feet of the soil, regular watering is preferable to sometimes deep soaking. Raspberry requires 1 to 1.5 inches of water per week from flower to harvest. They need good drainage to avoid waterlogged roots. Excessive wet roots cannot absorb enough oxygen for plants to survive. 
  • Raspberry hates wet feet. Standing water soil causes disease problems and root suffocation. Plant Raspberries in raised beds or mound the soil in ridges before planting if drainage is a problem. Whatever the soil, add organic matter in every season.

Do Raspberries only fruit once?

  • There are two varieties of Raspberry; the ever-bearing variety produces fruit twice, once in the summer and then in the fall, and grows berries every year from the first year. A variety grown in summer produces fruit only once in early summer. The fruit does not appear on the new plant grown in summer until the second year.
  • They bear one crop each season in summer (often June or July). The ever-bearing Raspberry (also known as fall-bearing or autumn-bearing) produces berries on new canes. They bear the fall crop and can also produce fruits next summer. 

Can Raspberries and strawberries be grown together?

  • You should not plant Raspberry bushes in an area where Potatoes, Tomatoes, Brinjals, or Strawberries have been grown in the last five years. They should also not be planted near these growing plants because of blights and other fungal diseases, such as verticillium wilt, which can spread from these plants to Raspberry. 
  • Good companion plants for Raspberry include Clover, Lavender, Garlic, Onions, Chives, Marigold, Nasturtium, Oats, and Buckwheat. You may also want to avoid applying Fennel or Strawberries nearby.
  • Avoid planting Raspberries near similar crops such as Boysenberries, Blackberries, or Gooseberries to prevent the transfer of soil-borne fungus diseases. 

Do Raspberries like wet soil?

  • Consistently moist soil will work best for berry plants. Moist soil gives the right amount of nutrients and oxygen to the roots. Rich, well-drained soil can help your Raspberry stay healthy.
  • Raspberry grows well in a wide range of soil types. They grow best in well-drained, fertile soils with a pH of 6.0 to 6.8. Raspberry grows poorly in heavy soil or poorly drained soil. Poor soils can often be improved by adding well-rotted manure or compost.

Why are my Raspberries small?

Broken canes and damaged stems cannot feed the formed fruit properly, resulting in diminished Raspberry. Areas with air, heat, and cold or high use of pesticides can limit the ability of bees and other pollinators to do their work. Flowers are not completely pollinated and produce partial fruit. Raspberry grows best in raised beds filled with rich, fertile soil. They require at least 6 hours of direct sunlight daily and 2.5 centimeters of rain per week.

How deep are Raspberry roots?

  • Raspberry spreads through an extensive underground root system. Growing Raspberries in raised beds require a planter at least 18 to 20 inches deep to accommodate their growth. 
  • Raspberry has quite shallow roots, and if the new canes from below the ground are too deep, which you are aiming to establish a new plantation, may not come through. Therefore, the canes should be planted individually, except for the 15-inch roots only covered with good friable soil, but no more than just covering. 
  • Avoid deep plantations; the first roots should not exceed 5 centimeters above the soil surface. After planting, cover the soil with 7.5 centimeters of heavy organic matter such as garden compost.


Raspberries are perhaps the most delicate fruit. You should eat raspberries within a day or two of picking them. Raspberry comes in various colors: red, black, purple, and yellow gold. When it comes to harvest time, there are two types of Raspberries, summer harvest types, and fall harvest types. You can extend the harvest of these sweet fruits if you plant some of the two.
