Can you grow sweet peas in hanging baskets?

The short answer is yes you can. The long answer is a bit more complicated and it depends on the variety of sweet pea you grow.

You need to grow a dwarf sweet pea in hanging baskets, regular sweet peas are just way too big to grow in a hanging basket. Dwarf varieties can do really well in baskets and there are some varieties specifically bred to be grown in hanging baskets.

What varieties to grow

Obviously, it needs to be a dwarf sweet pea as I said earlier, but which dwarf variety, there are a lot out there. I love Sugar N Spice from Thompson and Morgan. This is a specially bred hanging basket plant.

It is full of pinks and purples and smells absolutely delicious.

How to grow sweet peas in hanging baskets

Soak your seeds before planting for 24-48 hours, I did a sweet pea sowing experiment and this came out as one of the best methods along with using a heated seed mat.

Plant in a root trainer if you have one and use high-quality compost, not seed compost for these sweet peas. This is because they are going to need as much nutrition as possible with them being packed into a hanging basket so we want to use good compost even now.

when your sweet peas have one or two pairs of leaves of them pinch out the growing tip. This will help promote bushier growth rather than vertical growth.

When your sweet peas have been pinched out and grown back to around 6″ then it is time to transplant them into a hanging basket.

I like to really pack them into my baskets as this is how you get the best display. In a 30cm basket, I can put 4 or even 5 plants.

Because they are so packed in you will need to feed them often once they have got going. They are going to be competing for nutrients so you want to provide plenty of food for them to gobble up.

You could also try growing your sweet peas in pots. Like hanging baskets, dwarf varieties will tend to do best in pots.

The traditional season for sweet peas is June and July but with the right care and attention, they can be both started earlier and grown later into the season. Regular deadheading of sweetpeas can massively prolong their flowering period.

How to germinate sweet peas?

I like to soak my sweet pea seeds in water for 24 hours before planting them in a seed tray. This soaking helps to break down the tough shell around the seed allowing them to germinate better.
