Make sure that you dig the soil adequately, as this will help the roots to grow deep inside it. Add some organic manure to the soil to make it more fertile. You also need to check its pH. Ideally, it should be between 5.8 and 6.5. If you find that it is lower than this, then you need to add lime to the soil to raise the pH.
The next step is to decide which variety you want to plant. It is advisable that you go with the everbearing variety, as it grows prolifically, and you will get a good harvest.
Dig the soil up to a depth of six inches, and plant each seedling 2 - 3 inches apart. When you have a bigger plot of land for gardening, you can grow raspberries in rows, just like strawberries. For planting them in rows, you need to keep a distance of around 8 - 10 feet in between them.
Water the seedlings every second day, or every day if the site receives 6 - 8 hours of the afternoon sun. Once the seedlings begin to grow into thick bushes, you might need to provide them with support like a trellis. Installing a trellis around them is a good idea, as it provides support to them when they are laden with fruits.
Planting the raspberry bushes is not enough; you need to take good care of them, too. This mainly consists of using a good quality organic manure. Avoid chemical fertilizers that are high in nitrogen as fruiting season approaches, as this will hamper the growth of their fruits.
These plants require a high level of moisture, and you need to make sure that their roots do not dry out in the harsh summer months. Thus, water them without fail. For pruning them, cut back the canes up to an inch from the ground, after they have been harvested.
You can also grow raspberries from seeds. For this, you will need to propagate the seeds in a small patch of land. When the seedlings develop after few weeks, you can transplant them in their permanent location in the garden. Thus, with proper care, you are sure to be rewarded with a good harvest.
