Monty Don has revealed a clever timing trick for a popular plant he always grows in January.

Writing on his blog, the Gardeners' World presenter explained that now is the perfect time for sowing chilli seeds in trays — but timing is key when it comes to keeping them hydrated.

"Chillies are always the first seeds that I sow in the new year. They can be slow to germinate and certainly need some heat, either on a heated bench or on a windowsill above a radiator," he said.

"I tend to sow them in seed trays rather than plugs and then transplant them to plugs as soon as the seedlings develop true leaves, potting them on again in March and then to their final terracotta pots in May.

"Chillies need plenty of water but hate being waterlogged, so use a free-draining compost and never water them after 5 pm to avoid the risk of them sitting overnight in soggy compost."

If you water them too late in the day, the waterlogged compost could suffocate the seeds. Excessive water prevents oxygen from reaching them, leading your seeds to rot and die before they even begin to sprout green.

Monty also has another secret to successful chilli growing, this time revealing his tip for weekly feeding.

He wrote: "Allow each plant as much time and opportunity to become big and bushy, feeding it weekly with a high nitrogen fertiliser (I use home-made liquid nettle feed) until the first flower buds start to appear in June and then switching to a high potash feed (liquid seaweed or homemade comfrey feed are both ideal) to stimulate as many flowers and subsequent fruits as possible on what by now should be a large plant."
