Make sure seedlings are ready to transplant
Make sure your basil seedling is ready to transplant. The basil seedlings can be transplanted outside or to the permanent container only after they have developed two sets of leaves.
Check weather conditions outside
Also check if the weather conditions outside are favourable for your young basil seedlings. Basil plants do not tolerate frost, so move them out a couple of weeks after the last frost, when the risk of frost is completely gone.
Separate the seedlings
Usually people sow three or four seeds in one pot, if that is the case you should first separate the seedlings carefully. To separate the seedlings, dig up the clump with a small garden trowel, making sure some pot medium comes out with the roots of the seedlings. Carefully grab the soil near the base of one seedling and separate it from the root ball, preserving as many roots as possible. Repeat this process until all the seedlings have been separated. Now your seedlings are ready to plant.
Plant the seedlings
Plant your basil seedlings in a place that drains well and receives a good deal of sunshine. To ensure your seedlings grow into large, healthy basil plants with a robust root system, plant them deeply, burying the stem in the soil up to the bottom set of leaves. Pinch off the bottom set of leaves before planting the seedlings. The part of the stem in the soil will sprout roots. Don’t forget to gently pat down the soil around each plant to eliminate air pockets.
Water the seedlings
Once you are done planting the seedling, water each plant with two cups of water, diluted with fish fertilizer. Then water your plants moderately, twice a day with lukewarm water until well established.
Pinching is necessary
To encourage a stockier plant with lots of branches, pinch your basil back as it grows, every time pinching the top set of leaves. For example, if your plant has developed four sets of leaves, pinch back the top two leaves, making the pinch right above the second layer.
Harvesting will encourage your plant to branch out and provide you with even more basil leaves.
