Why Raspberry Plants Don’t Produce?. Hello gardening friends, welcome to my gardening blog, I am Emaknya Benjamin (Benjamin’ mother). This time, I want to talk about raspberry plants.
One of my YouTube subscriber, some time ago asking Why his Raspberry Plants Don’t Produce?
So you who have raspberry plants in tropical countries, it’s been a year or two years you wait and you wondering why my raspberry plant doesn’t produce? what’s wrong?.
Here below five things why or causes of raspberry plants don’t produce fruit:
1. The first is about varieties
Some varieties like mine, these are Rubus spp, produce fruit in the first year. Some varieties produce fruit on the same branch or twig 2 times.
Choose varieties whose fruits ripen at different times. Like my raspberry, in the spring it produces a lot of fruit until summer is still fruitful too. In the fall until the winter comes no more fruit, so it only produces fruit in the spring to summer.
Raspberries which produce fruit in the first year of planting are called primocanes, have green stems.
Raspberry plants that bear fruit in the second year are called floricanes, the stems are slightly brownish.
Most varieties will bear fruit between 16 and 18 months after planting. Red raspberry fruit ripens between 4 to 6 weeks.
2. the second is about sun exposure
Raspberry plants, like other berries: strawberry blueberries and raspberry need direct sunlight exposure.
If your house or place to plant raspberries is not exposed to direct sunlight, then choose varieties that not need full sun and are tolerant to cold, for example, Boyne or Nova Nordic varieties.
The warmth of the sun enhances the quality of the raspberries, making it more flavorful and juicer.
Raspberry plants that have minimal direct sunlight will make the growth of fruit stunted or fruit that forms wrinkles and dryness.
If the plant is too dense trim the plants so that sun exposure to the raspberry plants is perfect.
3. the third is about fertilization
Fertilizers twice a year in the first year are planted. For my raspberries I use slow released fertilizer, There is fertilizer for 3 months and there is also fertilizer for 6 months.
This fertilizer releases the active substance not at once, but slowly. For fertilizers that are 3 months old, in 3 months the active ingredients will be released slightly, while for 6 months fertilizer, the active ingredient is released in 6 months.
The price is, of course, more expensive fertilizers for 6 months. In the 4 seasons, the fertilizer is given in spring in March and May. Use 10 : 10 : 10 NPK fertilizers.
The fertilizer that I use is specifically for various berry plants, so it can be used for strawberry blueberries, raspberries and other types of berries, including grapes.
4. the fourth about watering
When it comes to watering, watering needs to be done regularly.
in my place, spring doesn’t need much watering. During this summer, where the temperature rises and the growing media dries quickly, watering needs more.
Need more watering during the summer, than in spring and autumn. So if in Indonesia and other tropical countries, it really needs to be considered for watering, if it is the rainy season, it will reduce watering.
The planting media should not dry out, but do not have stagnant water.
5. Other reasons Why his Raspberry Plants Don’t Produce
do not plant adjacent raspberries, next to or planted with chili, tomato, eggplant, and strawberry plants because they are susceptible to the same disease.
Supporting a plant like a fence is called the raspberries trellis, so it’s like the branches will be erect and exposed to the sun.
The plants and leaves will, of course, be exposed to the sun well.
If the plants are too thick, the plants are exposed to good sun exposure.
most raspberry plants grow well on growing media tend to be acidic. For raspberries, it grows well at a pH between 5.6 – 6.2.
If you want to know the pH of your Raspberry planting media, buy a PH meter test kit, in the form of litmus paper, or there are also those using small tubes where you can insert a little planting media, then you can see the difference in color after knowing the pH of the planting media.
Or you can ask the nearest garden center.
To know PH plant is very important, because if for example, the planting media is too alkaline, of course, the raspberries will grow worse, so also if the planting media is too acidic is not good for growth.
The suitable PH for raspberry plants is 5.6 to 6.2.
