A calm, practical guide to starting tomatoes from seed — from choosing a mix to light, warmth and the quiet signs that the seedlings are ready to move.
Tomatoes are one of the most satisfying crops you can grow from seed. They are also one of the easiest to get wrong — usually from rushing, over-watering, or moving too early.
Choose your varieties calmly
Look at what your family actually eats. One beefsteak tomato plant can produce enough fruit for a week of salads. Two dwarf varieties in pots can do the same on a balcony.
Sow shallow, keep moist
Tomato seeds are tiny. A light covering of mix, pressed down, and a plastic dome or bag on top does more than any fancy propagator.
Wait for two true leaves
The cotyledons (the first round leaves) are food storage. Once you see the second pair of real leaves, the seedling is ready to prick out into its own pot.
Seedlings are fragile, but forgiving. They will tell you what they need.
Harden off gradually
Over a week or two, expose them to outside air for longer periods each day. Never plant out before the last frost in your zone.
