Potting on chitted chilli seeds

Having soaked our chilli seeds in tea; chitted them on warm, damp kitchen paper until they germinated; and sung sweetly to them… it is now time to plant them in some actual soil and let them do their thing.

The beginning of the new year is a cold, dark and lonely time for a seedling in the UK. We look after our chilli babies the best we can to stop them being affected by the January Blues.

So what exactly do we do?

Paper pots

Careful preparation is the name of the game. We make newspaper pots using a wooden pot maker. Each germinated seed gets popped into a warmed paper pot for the next stage of its journey

These pots are perfect for us because…

  • they are free,
  • made from recycled materials,
  • can be potted directly into a bigger pot, with minimal root disturbance
  • can be composted at the end of the season
  • No labelling mix-ups, just write on the outside of the pot.

Ok, so they take time to make and are a little flimsy. They can dry out quickly, especially on a heated surface or in direct sunlight but we love them and they work for us.

Paper pot production goes into overdrive as we attempt to keep up with the number of seeds that are germinating. 50 is our goal today, must get rolling!

Seed compost

The seedlings need very little to start of with as they are still being fed from the endosperm (food stash from within the seed). Use a dedicated seed compost as it is low nutrients, good drainage, small particles. All good for little roots trying to develop.

A couple of teaspoons of seed compost fill each pot. Don’t forget to write the variety on the outside BEFORE you water


Gently warm the paper pots filled with seed compost BEFORE the seedlings are put in the soil. This means there is no shock to the system and they should continue to grow as if nothing has changed.

We place our pots on plastic windowsill trays. Lined with capillary matting. These tray conveniently rest on top of our radiators. Soil stays warm. Chillies LOVE it!

In addition to keeping the pots warm we use warm water when giving the seedlings a drink. Water from the base every few days. Careful not to overwater as waterlogged soil can check growth. Keep an eye on the outside pots as they will dry out quicker than the inner ones.

Warming nicely


Make sure the seedlings get as much natural light as possible. We started in January last year, grew under only natural light and had a pretty amazing harvest. We just had to rotate a lot. The light keeps the plants from getting too leggy in the early days. Consider a set of grow lights. We are about to embark on this journey with our first set of lights: The Phlizon 1200W. More will be said about this at a later date.


After a week or so, once the seed leaves are unfurled and looking a good strong green, we start to feed a weak solution of Chilli Focus. Not too much, or the roots can burn, just enough to keep the wolves at bay. 5mls to litre of warm water should do it.

Start to feed after each seedling has

And there you have it, a simple but tested way of looking after your precious babies at this early stage of the game.

How, where and when to plant chilli seeds

Chilli seed packets
Just a small selection of chillies we are growing this year

This is not our first year growing chillies. Over the years we have developed a number of tricks that make things more certain for us. Here are our top ten tips:

  1. Start as early as you dare;
  2. Soak the seeds in black tea;
  3. Chit the seeds on damp kitchen roll before planting;
  4. Warm the seeds as they are chitting;
  5. Use biodegradable pots for the first planting;
  6. Prepare the seed compost and pots ready to receive the germinated seeds;
  7. Keeps pots on a tray with capillary matting;
  8. Warm water from the base;
  9. Weak solution of feed from second week;
  10. Allow as much all round light as possible.

1. When to start germinating?

A real UK chillihead will start in December..no, November…perhaps late October? Hmm, when should we start the UK chilli season? It is really up to you. Seed packets state that February is a good time to sow. Many chilli growers will go for it just before Christmas. For us, it is a lovely way to start the New Year. Ordering seeds, waiting for them to arrive and getting the equipment ready is a tonic for the soul in the dark, wet month of January. And, at the Birdhouse, unless you want glitter as a soil addition it is best to avoid combining Christmas chaos and chilli seedlings.

A further element to consider is which species of chillies you will be growing. The more common types of Chinense, Anuum, Baccatum, Pubescens and Frutescens are all somewhat different in their needs and growing habits.

Chinense have a long growing season (over 100 days from sowing to ripe fruit). They can take up to 6 weeks with a higher heat to germinate. germination can be erratic if the temperature fluctuates too much. Chinense love consistent heat to flower and fruit well. The longer germination time is partially why we chit before planting: just so we can see what is going on. Start as early as you can accommodate to take advantage of the full Summer and Autumn sunshine.

Anuum are less fussy. You could get away with planting much later and still get a reasonable crop. Too early and you may end up with leggy plants on your hands. Anuum such as Jalapenoes will take a lower grower temperature if need be.

Baccatum are quick to pop, quick to grow true leaves and, later on, will happily grow outside well until the first frosts. Although they will go leggy if not given good light levels early on, they can be topped. This results in extra branches laden with glorious glossy chillies.

Pubescens are happy at lower temperatures. Perfect for the UK climate. They even have a little furry coat to keep them warm! No temperature demands for germination, happy to grow in a heated greenhouse in the early months and will keep fruiting and ripening outdoors well into mid frosts. A cloche would perhaps keep them going over Christmas.

Not sure about Frutescens as these are a first for the Birdhouse this year.

2. Preparing the seeds

Chilli seeds are encased within a tough outer shell. This protects them until the conditions are right to germinate. In a natural environment, seeds would perhaps pass through a bird’s digestive system. The digestive acids break the tough outer seed case down. We do not feed our seeds to our chickens, reclaim them and then plant them.

Some people do use a bird poo solution (yuck) to replicate this process. Other folk use a light sand paper to physically scarify the seed case. We soak our seeds in a black tea for 24 hours. This is a chemical scarification that starts the germination process nicely. It seems to increase the germination rate too.

3 & 4. Where to germinate your seeds

We start our chilli seeds off in a no soil environment. We repurpose takeaway containers, line them with damp kitchen towel and then place the seeds on the paper. Spray them with water, close the lid on two corners and put them in heated propagator. Above 20 degrees if possible. This means we can keep eye on germination. As each seed pops we put it into its own little labelled paper pot and move it out of the heated propagator to a sunny window sill. Some seeds take a little longer than others. Certain types (you know who you are) can take an age.

This year we might move them straight to the heated greenhouse. The temperature in their needs to be regulated though as anything under 10 degrees will check the teeny tiny seedlings. Not much point in planting nice and early if the seedlings sit a sulk for a month!

5 & 6. What to plant your seedlings into

Biodegradable pots are for us. Well, for the first pot anyway. There are a wide variety of bio pots available but we make newspaper ones ourselves. Grandfather Birdhouse’s copious stash of weekly papers is put to good use: firelighters, paper pots, chicken house flooring, art projects and cleaning the windows. Eventually, it all ends up steaming on the Birdhouse compost heap.

Why do we use bio pots? We pot the newspaper pots directly on into the next size pots when the roots show through the bottom. Potting up into bigger pots can result in wilted plants, leaves dying off and checked growth. Using biodegradable pots means those first roots are able to stay exactly how they have grown with minimal disruption. And, of course, it saves money, recycles materials and saves on waste.

We make pots in batches. You can really get a rhythm going. We have over 250 seeds currently chitting in our Old Faithful propagator. Must crack on with making the 2020 pots as surely there will be a seed popping soon.

Soon (hopefully) there will be little pots warming up on our sunny South facing windowsills, filled with fluffy soil, ready to receive the germinated seedlings.

We use a straightforward seed compost mixed with about 20% perlite to avoid everything getting too cold and soggy. No nutrients will be needed initially as we will be adding a light feed as soon as those seed leaves are up and above the soil. Until then the plant can feed itself from its own store.

7 & 8 & 9. Water, warmth, food, and light for the seedlings

Once the germinated seeds are ensconced in their petit paper pots the emphasis shifts to keeping them at a good temperature, in the best light and watered well.

Drenching the baby plants with a showering of freezing cold tap water is not going to get good results. Place the pots on trays with capillary matting. Keep the trays in a warm space, near a radiator or in the gentle winter sun. Water them only when needed. Use warm water, from the base.

After a week or so, introduce a weak feed to the water. Nothing too high in Nitrogen yet as we want strong healthy roots and structure rather than mega leaf growth at this point in the year. Our aim is to keep the plants as short and dark green as possible.

10. Let there be light.

We have wonderful South facing windows. Excellent. We have space for around 100 seedling. Good stuff. We are currently growing around 250 seedling. Hmm, not such great news.

How can we meet this challenge? Well, Father Christmas provided a set of grow lights. We need to investigate how to set these up and get them working best for the maximum number of plants.

Other than that, it will be the daily task of turning pots to avoid the plant stems lengthening to reach for the light. And then the rotation of trays so no plants are left furthest away from the windowsill for more than a day. It takes some time to do this but it really does give us a chance to look at each plant, check water levels, spot any fungus, remove any damped off plants and spy any early aphids.

And there we have it…the plan for the next few weeks. Now, come along seeds, let’s see some action!
