Those who can grow tomatoes from seed outside should wait until the end of May to ensure there isn’t a surprise frost that could kill them off.
It’s preferable to sow tomatoes seven or eight weeks before they can be planted out as gardeners won’t want their plants outside if there’s a sudden drop in temperatures.
When planting tomato seeds, sow them in the usual way in a seed tray and only transport them into individual small pots when they have two “true leaves”.
However, Sarah has a “personal preference” when it comes to sowing her tomato seeds. She said: “My personal preference is to sow two tomato seeds into coir or Jiffy pellets, which can then be kept somewhere warm, I like to use my heated polytunnel benches.
“Once their roots have filled the pellet, I tear off the net and pot them on into a 9cm (3.5in) pot. After two or three weeks, the roots will also fill that, from which I’ll then plant them in a two-litre pot that is supported with canes and string stuck in at the side.
