Results of topping chilli plants

It was March 28th when the Big Snip occurred. The tops of the seedlings were unceremoniously chopped off and they have been nursing their wounds ever since. All in the hope that new side shoots would appear and make bushier, sturdier and more productive plants.

That was two weeks ago…what do the plants look like now?

Here they are, in all their glory: tight plants with side shoots a plenty. A bit awkward, in the teenage phase if you will, but their small leaves will soon catch up with their big leaves and all will be bushy and well.

What’s next?

The plants need to have a good space around each of them. They are currently wedged together on windowsill trays and under a grow light in our study. Not ideal. There are now some critical issues:

  1. Shortage of compost: many plants need potting on but compost is in short supply. We are reusing last year’s spent compost, mixed with extra perlite and garden compost. No grit this year as it is too expensive and difficult to get hold of.
  2. Over crowding: by not potting on yet we have larger plants in smaller pots, with less gap between each plant. Light, air flow and good space is what each plant needs to grow to its full size potential. All those new side shoots will grow leggy if they are over crowded.
  3. Pot bound root ball: yet again roots are starting to be seen from the bottom of pots. If they are not potted on the roots poking out will wither and the ones inside will become pot bound.
  4. Space indoors is running out: an entire room has been taken over by chillies. This is not practical anymore.

Solutions are coming.

A 900L bag of compost is on the way (there are also tomatoes, squashes, cucumbers, beans to consider you know). A 3m x 2m poly tunnel is ordered, staging is being prepared. Perhaps within this week our plants will be heading out into the great outdoors (heated poly tunnel).

Topping for a second time

We’ve learned a lot from the first topping…

Different varieties of chilli like topping in different degrees. Some just don’t seem to understand what to do and others get it right first time.

A good example of a slow learner is Poblano. At the initial topping, Poblano was topped carefully to leave four true leaves. All seemed well. However, each of the plants has grown just one (or maybe two) new branch from the leaf node. This has then become the main growing stem again. It’s like the Auxin only made it down as far as that node and stopped there. Result: minimal branching, one main growing point AGAIN.

Topped Poblano, falling back into its old habits: one growth spike, minimal branching.

The best in class when it comes to branching out has got to be the Chinense group. Again, they were topped to leave four true leaves. This was difficult as they were tightly packed. Every single node has sprouted a new branch. Result: lush, dense plants with plenty of growing branches to bear lots of fruit.

Just look at all those new shoots. The Chinenses may be slow to grow but when they do it is ALL GOOD.

Espelette seems to know what to do with itself once its top has been whipped off. The difference is obvious looking at plants that have and haven’t been topped. Well done Espelette. We salute you.

Left: topped plant with branching at every leaf node. Right: taller plant, no branching, beginning to show a Y at the top. Flower buds.

Overall, topping HAS resulted in the chilli plants growing extra branches, lower down, before they form the Y. It has delayed flower formation and therefore flower drop or fruit developing too soon. Sometimes chillies forget to produce more flowers if they have an early fruit or two.

The Demon Scissor Snipper has been back. A second topping has occurred. Any plant that had not yet formed a Y has had its new branches topped too. Mwwwhhhhhaaaaarrr!

Why? In aid of even bushier plants, with more flowers, less chance of branch snapping and plants that topple over. And of course, many more chillies!
