गमले का चयन
You can grow blueberry plants in ground as well as in large pots having 3 to 4 drainage holes at the bottom. But for successful pollination and fruit set you should plant 2 to 4 plants nearby. For this purpose purchase 3 to 4 containers.
Blueberry is a shallow root plant. And its root doesn’t go much deeper. The roots only grows to 10 inches deep. So a pot of 20 inches wide and 15 to 20 inches deep will be perfect for growing blueberries.
प्रसार के तरीके
You can either buy a young plant to transplant directly or high quality disease free seeds from the market. You can also grow blueberries from softwood and hardwood cuttings. If you have purchased young plant then you can transplant directly in the pot by using prepared potting mix.
But if you want to propagate from seeds or cuttings then you can follow the following procedure.
Propagation From Seeds
If you are germinating seeds of blueberry then make sure that it have been frozen for at least 90 days. To propagate blueberry plant from seeds, fill a small container of 6 inches with the potting mix. Make sure that the container have drainage holes at the bottom. You can also use germination tray for this purpose.
Sow seeds 1/2 inches deep and cover them with a thin layer of potting mix. You can keep 1/2 inches gap between each seeds. Apply water gently after sowing seeds. Keep the germination container in shade and maintain adequate moisture.
It will take near about 30 days for germination of seeds. Once you notice the growth of new seedlings then place the container under semi shade. It should receive filtered sunlight during early growth period.
You can also use peat moss for germination of seeds instead of potting mix. Once your seedlings reaches 2 to 4 inches of height then you can transplant it in the selected pot.
Propagation from Hardwood Cutting
You can also propagate blueberries from hardwood cuttings. For this purpose take during end of dormant season i.e. late winters, take 5 to 6 inches long cuttings. Take cuttings from the strong and healthy shoots.
Remove flower buds or discard the tip of the terminal end of the cuttings. Fill the container with peat moss and perlite in 1:1 ratio and do not add any fertilizer. Put 2/3rd of the cutting in the medium. And keep one shoot bud exposed.
Keep the pot in semi-shade and apply water gently. Keep the medium moist but not soggy. After few days you will notice development of new leaves.
Blueberry Plant Care
Once you are successful in growing blueberries plant then the next important step is to care for them. You need to know about sunlight requirement, watering frequency, fertilizers, pruning, etc. to care for your plant very well.
सूरज की रोशनी
Mature blueberry plant loves full sunlight. Place your pot in the regions where your plant can receive 6 to 7 hours of direct sunlight daily. But during hot summer days or extreme winters protect your plant.
For this purpose you can place your pot in semi shade region. Blueberry plant doesn’t grow much taller, it can grow from 2 feet to 12 feet tall depending on the variety. So even if you have planted directly in the soil then too you can provide shelter by constructing a temporary shade.
Blueberry plant loves moist but hates soggy soil. That means you have to apply water whenever the top layer of the soil in the pot seems try. But you also have to ensure good drainage in the pot to remove excess water.
The best practice is to apply a 2 to 4 inches mulch layer of either woodchips or saw dust. This will help to retain the moisture in the soil.
You can start fertilizing your plant from spring to fall. Stop fertilizing during winters. You can fertilize with half teaspoon NPK (10:10:10) once after every 30 days. You can also add a pinch of micronutrient solution.
There is no need of pruning in the first four year of plant growth. But, keep removing dead and decaying leaves or branches. After fourth year you can start pruning periodically. Prune the weak diseased part of the plant during early spring season.
This will help to keep the plant healthy and promote growth of new branches during the growing season.
