Hibernating basil is a bit difficult, but not impossible. Since basil is actually native to tropical regions, it needs a lot of heat and does not tolerate frost. We'll show you how to get your basil safely through the cold season.
Step by Step: How to Hibernate Your Basil
Cover the vent hole with a curved pottery shard (left) and fill with drainage clay (right)
The pot should have a diameter of about 20 centimeters. To allow the water to drain freely, place an upwardly arched pottery shard on the floor. For drainage, fill a 5 cm layer of expanded clay into the pot. Instead of expanded clay, you can also use gravel (grain size 8 to 16 millimeters). Unlike clay, gravel does not store water, but in winter this property is less important.
Cut the fleece (left) and place it on the drainage (right)
Cut out a piece of garden fleece to match the pot size. The water-permeable fabric separates drainage and earth. Carefully lay the mat on the drainage layer to keep the clay or gravel clean and easy to reuse later.
Fill substrate into the pot (left) and plant the basil (right)
Suitable substrate is flower or container potting soil. Special herbal substrates provide too little nutrients for the basil heavy herb. Fill the pot with a planting trowel. Gently hold the plant and add enough soil until the top of the bale is just below the edge of the pot.
Press earth (left) and pour well (right)
Use your fingers to press the bale all the way around. If necessary, replenish enough substrate until the roots are completely surrounded by soil and can grow in well. Finally, pour the plant well and drain off excess water. As long as the temperatures are above 10 degrees Celsius, the pot can stand outdoors.
Also 'African Blue' can be hibernate well
Basil 'African Blue'
Perennial basil is as frost sensitive as the classic Genovese basil. But the chances are better to cultivate it in the pot until next spring. The best way to work in the winter is with the variety 'African Blue'. This perennial breeding forms so decorative flowers that it can be planted in summer as an ornamental plant in flowerbeds. The cool season is best weathered bright and at temperatures of 15 to 20 degrees Celsius. If you have limited space, you can also cut cuttings from the large mother plant and overwinter them planted in small pots.
