Whether in the classic green pesto, on the pizza or in a cocktail - there is hardly any herb that we associate with summer and Mediterranean flair as much as basil (Ocimum basilicum). It shouldn't be missing in any herb garden. And if you don't have a garden, you can still look forward to a basil in a pot on the windowsill or in the balcony box. However, the demanding herb can be a real diva and needs to be treated correctly in cultivation, care and harvesting. So that you don't go wrong with the harvest and can harvest fragrant, green leaves for as long as possible, we will tell you everything about the correct harvest and storage of Ocimum basilicum.

When is the best time to harvest basil?

When properly grown and cared for, basil can be harvested year round. Perennial varieties even survive winter and can provide some aromatic leaves for the kitchen even in the cold months. However, the growth of the herb is greatly reduced in the cold winter months and significantly less should be harvested. It is therefore advisable to leave the basil alone as much as possible in winter and to refrain from harvesting. Some Basil varieties are only bred for a one-year cultivation period. These usually thrive from April to October and can be harvested during this period. After that, they usually die.

Overview: when is basil harvested?

• Perennial varieties: all year round (under optimal conditions)
• Annual varieties: April - October

Harvest and pick basil properly

Even if it seems so tempting to simply pluck individual leaves from the basil: So annual, Unwooded basil can never be harvested, because with this technique the shoots die quickly and the aromatic herbs stunted. To ensure a long life for your basil, you should only harvest the tips of the shoots. To do this, you can simply pinch off the stems above the last pair of leaves with your fingers or cut them off with scissors. New shoot axils will now develop from the leaf axes and the basil can thrive even more splendidly. Another advantage of this harvesting technique is that flower formation is delayed, which extends the harvest time of the aromatic basil leaves. Of course, basil can still be harvested when it is in bloom; however, the flowers change the aroma of the plant. Perennial shrub basil forms strong shrubs with woody stems. Individual leaves can also be plucked from this basil bush. Because in contrast to the tender annual basil, the shrub basil can handle the harvesting of individual leaves much better.

Overview: How is basil harvested?

• Do not pluck individual leaves from annual, non-woody varieties
• Pick or cut off the shoot tips
• To do this, pinch or cut off the stems just above the topmost leaf branch
• New side shoots then develop from the leaf axils
• Individual leaves can also be plucked from woody shrub basil

The harvest-fresh use of basil is ultimately unbeatable.

The basil oil can then be used for cooking or for salad dressings. You can also make basil very durable by processing the leaves freshly harvested into pesto. Other ways to preserve basil for longer are soaking it in salt or white wine vinegar.

Of course, basil can also be frozen and dried. You will find out how this works in the next few sections.

Freeze the basil

A common question is whether you can freeze basil. The simple answer to this question is: yes, basil can be frozen. However, basil loses its aroma in the freezer and becomes slightly mushy and brown. To counteract this, there are various ways to optimize the freezing of basil. One option is to blanch the leaves before freezing them. This way they keep their aroma and color better. Another tried and tested method is to put the leaves of the aromatic herb in the freezer with water. For example, the leaves can be frozen in ice cube molds so that they can be easily portioned. They are also great for use as Cocktail herbs. Last but not least, basil can also be frozen as a pesto. The additional oil and salt retain the aroma and the pesto will last longer in the freezer.

Dry the basil 

Again and again I hear that basil can be dried very well. However, the air-drying process is not particularly suitable for this herb. The degradation of the taste-giving essential oils is simply too great in basil due to the dehydration. The dried basil tastes like almost nothing anymore. In general, the faster the drying process, the greater the loss of taste. Nevertheless, dried basil can be used as a spice or to refine herbal salt.

How do you dry basil?

• In a dry, dark place
• Hang whole stems upside down
