Do Basil Seeds Need Light to Germinate? Tips & Care

Basil is part of the Lamiaceae family. A variety of herbal plants thrive here, all of which belong to the light germs. This circumstance makes sowing a little less complicated, as the following instructions show.

Choose the optimal date for sowing

The name implies the central factor for successful sowing. For the light germinators, a maximum amount of light is required to bring the seeds to life.

It can be dark in some regions until the end of March. Sow the seeds from the beginning of April and strong and vital young plants will develop before they are planted out.

This is how you sow light germs perfectly

If the seeds are given a lukewarm bath in chamomile tea for 2-3 hours beforehand, this measure naturally prevents mold from forming. Without allowing the seed to dry again, continue with these steps:

  • Fill a multi-pot plate or seed tray with Perlite, coconut fibers, peat sand, or seed-soil
  • moisten the substrate with a fine shower
  • Then sow the basil seeds
  • sow 1-2 seeds in each pot
  • Press the light germs down a little without sieving them over
  • cover the seed pot with glass or cover with foil
  • ideally in a heatable mini greenhouse.

Although a lot of light is required for germination, sowing must not be in direct sunlight. A partially shaded window seat is therefore an advantage. At warm temperatures of 20 to 25 degrees Celsius (68-77F), germination starts within 5 to 14 days, depending on the basil variety.

Proper care until germination

The cover of the culture vessel creates a humid and warm microclimate, which has a beneficial effect on the germination process. At the same time, it carries the risk of mold growth.

Therefore, air the glass or foil daily. The same applies to the indoor greenhouse. The substrate must not dry out at any time. Fertilization is not yet done in this phase.


Anyone who prefers direct sowing in the bed will not like to expose the delicate basil seeds to the weather without protection. A seed helper like vermiculite is just what you need. The feather-light silicate flakes are scattered very thinly over the seed, protect the light germinators from sunburn and store the water without impairing germination.
