First, the choice of pots
If you choose to plant blueberries in pots, you should be especially careful when choosing blueberry pot, suitable for the growth of blueberries is the most important pot. For example, the air permeability must be good, it is best not to choose plastic pots, because the air permeability and comfort of plastic pots is not good at all, but also easy to break.
The root system of blueberries grows very fast and branches very much, you will need to choose a larger size and deeper pot, so as to ensure that its root system grows freely, so as to let the blueberries bloom more flowers and bear more blueberry fruits.
Second, choose the soil
After we choose a good pot, the next step is to choose the soil suitable for planting blueberries, usually acidic soil blueberries prefer, because alkaline soil will cause some damage to the plant, but also affect the blueberry blossom and fruit. We can add some loose leaf soil, river sand, and decayed leaves in the acidic soil home, so that then add some animal manure fully fermented, so that the soil has more nutrients, only in the future growth of blueberries more vigorous, more healthy.
Cultivate blueberries
When we cultivate blueberry seedlings, because the bottom of the pot will have a large round hole, so we first need to pad on the bottom of the pot with some larger particles, so that its permeability becomes very good, the purpose of doing so is to avoid the watering time, the water accumulates in the soil, so that the blueberry root system rot phenomenon.
Usually, the cinderblocks are added to the bottom of the pot, then the acidic soil is placed inside the pot, and finally the blueberry seedlings are planted inside the pot. After planting, we need to fully compact the surrounding soil, so that the root system and the soil will be a little better combination, the last step and then water, put into a ventilated place, and finally in the watering.
After watering within a week do not move back and forth blueberries, let it through the sunshine, after the state of its plants slowly slowed down after the second watering.
How to water
There are tips when watering, because blueberries for water is not very strong, it is not afraid of drought, but afraid of too much water, so we planted blueberries when watering not too hard. If the soil inside the pot becomes very dry, you can water again, usually one week to blueberries watering once is completely enough.
Too much water can cause yellowing of the leaves and root rot, which can affect the health of the blueberry. Especially after the blueberry's buds have grown, this is the time of year when too much watering can cause the buds to fall off. During the process of planting blueberries, make sure you watch carefully to see if there is a lack of water in the blueberry soil.
If there is a shortage of water, you can water them again. If there is no shortage of water, do not water the blueberries. If you plant blueberries in pots on the balcony, in the summer, because of the hot climate, the air is dry, the water is easy to evaporate, this time we have to open the window after each watering, let the blueberries ventilate, so that the humidity inside the soil will be preserved very well.
Fertiliser
All things are inseparable from the nourishment of fertiliser, blueberries also need fertiliser, avoid in the beginning of the planting of blueberry seedlings can not be fertilised, this time the fertiliser will be directly to the blueberry root system burnt. When planting blueberries 8 months to a year after the fertiliser is no problem at all, the general fertiliser season is in early spring.
Use poultry manure fully fermented or soybean cake fertiliser to fertilize the blueberries before they bloom, and you can also add some more phosphorus and potassium elements to the fertilizer. This will help the blueberry buds to blossom and sit quickly. You should also add some phosphorus and potassium fertiliser or potassium phosphate solution to the small fruits when you notice that they turn green after they grow, so that its fruits will grow faster and become darker in colour.
Sixth, sunlight exposure
Blueberry is a fruit tree that can blossom and bear fruit, so we must let the blueberry receive a lot of sunlight during the planting process, if the sunlight exposure is not enough, the blueberry leaves will be yellow, and the flowers will be less, and the fruits will be less.
If you keep your blueberry in a dark, humid place for a long time, it will basically not bear any fruit. Growing blueberries in drainage gutter on your balcony is actually very simple, and by doing the above few things right, you will surely grow high-end, nutritious, and outstanding blueberry fruits. Dear friends, have you mastered all these growing tips? Once you have mastered them, you can start growing blueberries.
