Starting the season with sweet peas

It’s too early to really start thinking about sowing seeds but one thing I will be doing this month is sweet peas.

Many people sow in the autumn as it produces earlier flowers. I find it’s a job too many at a busy time of year so always leave it until now. It’s also one less thing for me to keep going over the winter when space is tight in the greenhouse, potting shed and cold frame.

I’ll be starting the seeds off in the heated propagator – a bit of heat stops the seeds sitting in cold, damp soil for too long and the propagator is a bit of protection from the garden’s mice.

They may have looked a bit bedraggled, but the sweet peas were flowering weeks later than usual.

Sweet peas have a long root run so something deep is best. You can use the inner cardboard tube from loo rolls or make pots from newspaper. However, they won’t be going out into the ground for some weeks and I’ve found those to be fine in the short-term but they tend to fall apart eventually. So, I’ll be using RootTrainers. They may be plastic, which I’m trying to avoid, but I’ve had them for years and keep reusing them.

‘Gwendoline’ was one of the new sweet peas I grew.

Last year was a bumper season for sweet peas in my garden. Unbelievably, I was still picking flowers in October.

Adding some compost and newspaper improved the soil before planting.

The damp summer undoubtedly helped but I also prepared the soil well before planting, adding newspaper and a generous helping of coir-based, peat-free compost, which I was given to trial by FertileFibre. I very much doubt my thin, sandy soil would have produced the same results without those additions.

I loved the markings on the petals of ‘Balcony Mix’.

I trialled several varieties of sweet peas last year and discovered some beauties.

One of my favourites ‘Balcony Mix’ from Mr Fothergill’s. Unlike my usual tall sweet peas, it is shorter and ideal for containers. I grew it in a pot on the patio where we could see the rather beautifully marked flowers.

‘Blue Shift’ may have been more purple than blue but was still beautiful.

‘Nimbus’ from Chiltern Seeds was another with delicately marked petals, while ‘Blue Shift’, also from Chiltern, was, like many so-called ‘blue’ flowers more purple in colour. That said, I really liked it and will be growing it again this year.

‘Nimbus’ was another pretty variety.

‘Gwendoline’ (Chiltern Seeds) was chosen because of the name, which goes back in family history. It turned out to be a robust plant with pretty pink flowers.

‘Pink Champagne’ gave a mix of pink shades.

‘Pink Champagne’, also from Chiltern, gave flowers in shades of pink, which is a good option, if you want a mix but don’t want to sow more than one packet.

One of the shades in ‘T&M Prize Strain Mixed’.

The same idea but with a wider range of colours came in ‘T&M Prize Strain Mixed’ from Thompson & Morgan, with pink, purple and white flowers.

I’m hoping to sow more new varieties this year. Fingers crossed for another long season of blooms.

  1. I’ve tried growing sweet peas a couple of times but never had any success. Please will you update us on everything you do and I’ll follow your advice x

    1. I think the secret is soil prep before you plant. I always dig a big hole, line it with newspaper – acts as a water sump – and fill with compost, either homemade or brought in. Regular watering (unless we get a wet summer!) and picking to stop them setting seed keeps the flowers going. There’s more detail here: https://thechattygardener.com/?p=6610 🙂
