Have you ever wondered what’s inside a plant seed and how can such a tiny thing become a full-grown plant? How should you store your seeds and help them to grow successfully? Read this blog post and find out!

The plant seed contains an embryo, which has already the first leaves, root and stem. Seeds also contain food reserve for the future plant. That enables the plant to grow until it can photosynthesize and thus produce its own food. Some plant species’ seeds may stay viable for many years, others only until the next growing season. Seeds need to have suitable conditions to start the germination. Seeds stay viable for a long time if they are dry, but they need moisture in order to start germinating. Also oxygen and suitable temperature are important. Some seeds germinate better in the dark, some need light. Usually big seeds should be sown under a thin layer or soil or sand, that keeps them moist. Small seeds contain so little food reserve, that they need to know that they are very close to the surface and thus can quickly grow leaves and roots. If they are sown too deep, their food reserve will run out before they reach the surface. If the seeds sense light, they know that the surface is near and they can safely start germinating.

 

Some seeds require a long, cold period and then a warmer period before they start germinating. This is to prevent them from accidentally germinating just before winter. Remember to store your seeds in a dry, dark and cool place! Plantui Plant Capsules can be kept in a fridge, if they are sealed to prevent moisture to crawl in.

Have you noticed that Sweet Blond seeds are big and orange? The reason for the strange color is pelleting. That is a common procedure with vegetable seeds. Pelleting makes all the seeds even in size and form, which makes manual or mechanical sowing easy and precise. The seeds are pelleted with an inert material, that dissolves with moisture. Bright colors can be added so that the farmer can easily observe the result of the sowing. Sweet Blond seeds have a bright orange color, because Plantui uses professional seeds, same as for example greenhouse growers use.

Seeds can also be treated with pesticides or fungicides. They protect the small plant from fungal diseases or pests. Some pesticides are bad for the environment, but adding pesticides on the surface of the seed might be more environmentally friendly than spraying the plants with pesticides later, because seed treatment requires very little amounts of pesticide. None of the seeds in the Plantui selection are treated with pesticides.
