Questions

Questions answered

Short, self-contained answers about growing plants from seed — three topics with four questions each. Every answer stands on its own, so you can start reading anywhere. We explain the general principle and point you to where you can find exact details for a particular crop, but we do not name varieties, seed companies, shops or products, and we do not invent precise timings where they depend on conditions.

A seed packet usually holds more useful information than it seems. Before searching for an answer online, read the packet carefully again.

— Editor's note

Seeds and germination

How should I store seeds at home?

In a dry, cool place, away from sudden changes in temperature and humidity. A tightly closed box or jar in a cupboard works well, away from radiators and the cooker. Label the packets if you decant the seeds.

Can I sow old seeds?

You can try, but germination declines the longer seeds are stored. Test them on a damp paper towel before sowing: the result will show whether to sow them as usual, sow more thickly or get fresh seeds instead.

What is stratification and which seeds need it?

It means keeping seeds cold and moist before sowing. Seeds of some plants that germinate after winter in the wild need it. Whether your seeds need it is usually stated on the packet or in a reference book on that crop.

What does it mean when a variety is on the register?

In Russia, varieties approved for use are listed in the State Register of Breeding Achievements, and seed production is regulated by the Federal Law on Seed Production, adopted in 1997. Being on the register does not mean a variety will suit your particular windowsill.

Seedlings

Why do seedlings get leggy?

The main cause is too little light. The plant stretches towards it, and the stem becomes long and thin. Air that is too warm often makes it worse. A brighter spot, a grow light and a slightly cooler room all help.

When should I prick out seedlings?

Usually after the first true leaves appear, which look different from the seed leaves. The exact timing depends on the crop. Plants that dislike transplanting are better sown straight into individual containers.

How often should I water seedlings?

Not on a schedule, but according to the compost: when the top layer has dried. Overwatering harms roots just as much as drying out. Excess water should drain into the tray, and it is best to empty it from there.

Do seedlings need feeding?

Fresh seed compost usually contains enough nutrients for the early stages. If you decide to feed your plants, choose a product meant for seedlings and use it strictly according to the manufacturer's instructions, without exceeding the recommendations.

Microgreens, herbs, houseplants

How do microgreens differ from sprouts?

Sprouts are eaten together with the seed and root soon after germination. Microgreens are grown in the light until the seed leaves or first true leaf appear, and are cut just above the growing medium.

Which seeds should I use for microgreens?

Look for a note on the packet saying the seeds are intended for microgreens or for eating. Ordinary seeds for sowing outdoors may have been treated, and such treatment is not meant for food.

Why are culinary herbs so slow to come up?

Many herbs have small seeds and germinate slowly, and some of them need light. Sow them shallowly, keep the compost evenly moist and be patient: slow germination does not yet mean the sowing has failed.

Can I grow a houseplant from seed?

Yes, many houseplant flowers are grown from seed, although it takes longer than rooting a cutting. It is important to meet the light and warmth requirements on the packet and not to rush repotting.

Information is current as of the date of preparation. Sowing and planting-out dates depend on your region, the weather in a given year, how much light your window gets and the temperature in your home, so go by your own conditions and the instructions on the seed packet. This guide explains general principles and is no substitute for advice from an agronomist or a botanical garden specialist.
