Sowing your hardy biennials and even annuals in the summer will help you get stronger plants in the spring.
A plant is said to be biennial when it is cultivated over two years.
It is usually sown between July and September and flowers in the spring of the following year.
Your seedlings will take advantage of the morning dew, the heat stored in the earth to grow rapidly.

Sowing in the ground or in pots
Sow your transplanting biennials such as broadcast daisies, pansies and forget-me-nots on loosened soil by mixing the seeds with sand when they are tiny.
- Distribute them well and cover them with a little finely sieved potting soil, to a thickness of 1 or 2 mm.
- Tamp the soil with the back of a rake or a wooden plank.
- Water in fine rain with a watering can fitted with an apple so as not to dig up the seeds.
You can also make these seedlings in boxes to protect the seeds from sun burns.
- When the seedlings have two leaves, put them in pots.
- Set them in place after the first fall rains, in still warm soil so that they have time to begin to take root before winter.
- Water and watch for slugs.
- You can also keep a few plants in pots and replant them in the spring.
Sow those that don't like to be transplanted, such as digitalis, cockroaches or evening primrose.
Remember to put a label near your seedlings, so as not to confuse these small seedlings with the herbs to be pulled up during your weeding.
More resistant annuals
Annuals are usually sown in the spring, but sown in August your plants will be stronger and flower more.
Their deep rooting will make them more resistant to drought. Broadcast poppies, nigella, California poppies without burying them in the earth.
As a precaution, save a few seeds for sowing in the spring, in case the winter is too cold.
