How to Grow Raspberries? A Detailed Guide to the Latest Planting Precautions

Raspberries are also called "pao." Many people picked raspberries on the mountains when they were children. Back then, the wild raspberries on the mountains were the fruit and free delicious snack for many of us, but now wild raspberries are very scarce, because most of the land has already been developed, and raspberries have lost the land they need to survive. However, a wave of raspberry cultivation has risen in the market, which can preserve this deliciousness and at the same time preserve many people's childhood memories. What Qinnong Network wants to tell everyone today are some small issues to pay attention to when planting raspberries, but they have a great impact on raspberry yield and service life. Interested friends can read carefully.

1. Variety Selection

Raspberries actually look very similar to strawberries, and their taste is also sweet and sour, except that their flavor is different from strawberries, and the growing medium is also different. There are many raspberry varieties, such as red raspberry, black raspberry, Hongbaoyu, Siyue Pao, Liuyue Pao, Tuopan, and double-cropping red raspberry, etc. There are about ten to twenty types in total, but the best varieties for artificial cultivation are double-cropping red raspberry or black raspberry. Double-cropping red raspberry can be harvested twice, while black raspberry naturally grows more vigorously than other raspberries and has a higher yield, and its nutritional profile and taste are both excellent.

2. Fertilizer and Water Management

Do not assume that just because raspberries used to be wild, they have no requirements for nutrients and water. In fact, that only shows that they have strong adaptability and can still survive, bloom, and bear fruit in harsh environments. If you want the raspberries you plant to have a higher yield than usual, then you must do a good job in fertilizer and water management. First, let us talk about fertilization. Apart from the base fertilizer, we also need to apply topdressing twice. The base fertilizer is generally mainly farmyard manure, and an appropriate amount of urea and phosphate fertilizer also needs to be added. The first topdressing is at the flowering stage, mainly using nitrogen fertilizer, which can extend the flowering period. During this period, some non-toxic agents for fruit retention and fruit strengthening can also be sprayed to promote fruit growth. The second fertilization is one week after fruit set. At this time, mainly phosphate fertilizer and potassium fertilizer are used to promote fruit growth, promote root growth, and prepare for a high yield the following year.

3. Branch and Leaf Management

⟦NL>We all know that during the growth process of raspberries, their branches and leaves grow continuously and also keep extending outward, so when planting we must pay attention to density, giving them enough space to spread their branches and leaves. After the raspberry plants survive after planting, some new branches and leaves will grow. At this time, we can cut off the older, more fragile, or diseased branches and leaves to reduce unnecessary nutrient loss. When the newly grown branches and leaves reach 40 to 50 cm, we can pinch off the tips of the new branches. After about five days, several side branches will grow again. Increasing the number of raspberry branches is also a way to increase yield. After each raspberry harvest, we also need to prune the raspberry branches and leaves once. This time it is mainly for a high yield the following year, so we need to cut off the branches that have borne fruit and then wrap them with plastic wrap. The following year, new branches will grow and bear fruit again.

4. Disease Control

The most common diseases of raspberries are stem rot and powdery mildew. Stem rot mainly harms the newly grown branches of raspberries. The initial symptom is the appearance of many black spots on the stem, which then slowly damages the branches. In the most serious cases, the entire plant withers. The control method is to spray 500-times diluted thiophanate-methyl solution, or 500-times diluted 40% phosethyl-Al solution, or 500-times diluted thiram solution. As for powdery mildew, there is no need to say much. It can be controlled by using 1000-1500-times diluted 25% triadimefon wettable powder. The main insect pests are moth pests and beetles. We can use trapping or directly spray with pesticides to kill them. Commonly used pesticides include trichlorfon and dimethoate emulsion.

5. Harvesting and Fresh-Keeping

Raspberry harvesting needs to be carried out in batches, each time harvesting only those fruit trees that are fully ripe, leaving the half-ripe and green raspberries for the second and third harvests. When harvesting ripe fruit, also pay attention to sorting good-quality and poor-quality fruit separately. Harvesting must be timely. It can be one day earlier, but it must not be too late. If it is late, the raspberries will either have already rotted or fallen to the ground, so the harvest time must be grasped well. Finally, raspberry fruits are relatively fragile and have a relatively short storage time, so we can use modern preservation technology for fresh-keeping, such as low-temperature preservation and air-filled packaging, etc. If the fresh-keeping is not done well, then the raspberries will have no value.
