A new way to grow sweet peas: it’s kind to plants and the planet

I’ve discovered an amazing new way to grow sweet peas that is better for the plants and better for the planet.

I love growing sweet peas and always start them off indoors in late winter/very early spring to be planted outdoors in early May once the weather warms up.

Summer wouldn’t be summer without sweet peas – no wonder they were voted the UK’s favourite garden plant

I’m trying to move away from using plastic in my gardening projects but found that cardboard loo roll tubes, often suggested for sweet peas, collapsed too quickly over the course of the six/eight weeks that I grow them on under glass. The tubes and fibre pots on the market had the opposite problem of steadfastly trapping the roots within their walls unless you absolutely drenched them.

So I ran a trial this year to see if I could use Wool Pots for the early stages and pitted them against plastic pots – and the results were fantastic.

I used the same size pot, the same compost and the same type of sweet pea for my trial.

I always pre-germinate my sweet peas and I’ve attached a link to the popular sweet pea tutorial we made last year giving step by step instructions, (but this was made before I discovered Wool Pots so please excuse the use of black plastic pots in it !).

Growing sweet peas using our tried and tested method is easy – even Caroline managed it

The plants in the Wool Pots looked healthier from the outset and the root growth was more evenly spread around the pot, presumably due to the air flow in and out of the woollen walls of the pot. The base and walls of the Wool Pots started to decompose naturally after about 8 weeks but the rootball held together nicely.

From the outset the plants in the Wool Pots seemed more robust, with bigger, greener leaves

The game-changing aspect really came into play at planting-out time because instead of tipping the plants out of pots or root trainers, the whole woolpot is dropped into the ground where the remains of the woollen walls gently decompose to provide an extra little boost of natural fertiliser to the roots.

Being able to plant the whole pot in the ground without disturbing the roots was a real game-changer

In comparison, the plants grown in plastic pots had congested roots coiled at the bottom which had to be manually untangled to encourage them to branch out and explore their new environment. This gave them a check to their onward growth and made them slower to establish.

It had been a race to the bottom in the plastic pot with the roots in tight coils that had to be brutally unpicked

As an extra bonus the rim of the Wool Pot remained intact to provide a natural slug barrier for the young plants.

The rim of the Wool Pots is the last bit to decompose so acts as a natural deterrent to slugs who dislike crawling over wool

I was left with not only some great little plants that had the best start in life, but also a clear conscience that I wasn’t adding to the 500 million (yes that’s half a billion) black plastic pots that we take to land-fill each year.

The fact that the Wool Pots are manufactured from sheep’s wool sourced in the UK giving our beleaguered farmers some value to an otherwise wasted by-product was the final reason that I intend to use Wool Pots for my sweet-peas from now on.
