How to Grow Sweet Peas in Hanging Baskets?

Sweet Peas are long climbing vines that produce pearly white with inky purple flowers annually, suitable for patios or balconies in hanging baskets.

To grow Sweet Peas, collect seeds, pre-teat them at a cold temperature and sow them in the hanging basket with drainage capacity and porous and nutrient-dense soil. Provide the seeds with 55-65º F temperature and 78-90% humidity, and slightly alkaline soil to germinate. 

You can apply similar conditions for each variety of Sweet Peas to fill the indoors and outdoors with fragrant blossoms!

Can All Varieties of Sweet Peas Grow in Hanging Baskets?

Watch out for the varieties of Sweet Peas before bringing them home, as every type does not fit in hanging baskets.

Tall varieties can reach 8 feet under the support of trellis or bamboo tripods. In contrast, the dwarf varieties grow about half the size of Tall ones, suitable for hanging baskets.

Patio sweet peas grow best in containers and hanging baskets without the presence of other plants.

So go for dwarf, bushy varieties of Sweet Peas to get heavy blooms with fragrance and a spectrum of color.

1. Virgo

First on the list is the Virgo, attaining a height of one meter in about 1-2 years under full sun with partial shade.

Each Virgo plant branch can yield four lovely white blossoms during summer and early fall.

The best part is that the Virgo can spread up to 1 meter, similar to the length of the trailing plants, making your pot appear bushy instead of leggy.

So provide your Sweet Pea variety with a pot having the organic-rich mix and enough drainage holes to enjoy the full blossoms.

You can also opt for Boston Fern and Curly Spider Plant to grow in the basket. 

2. Flora Norton

Second on the list is Flora Norton, famous for its bluish hue giving about three flowers per stem in summer.

The plant can attain a mature height of 1-1.5 meters in about two years under 6 hours of full daily sun with partial shade.

Moreover, you can enjoy the spreading trails up to 1 meter during fall and cold days.

Flora Norton falls under the heirloom type or ‘Old Fashioned’ type of Sweet Peas and produces strongly scented blooms as a sweet perfume for indoors.

So bring the Norton variety of Sweet Peas home and nourish them with deep, rich, moist soil in a hanging pot with enough drainage holes.

3. King Edward VII

Next is the King Edward VII variety, with long climbing vines extending up to 1.8 meters, giving crimson blooms in summer and early autumn.

Also, given the plant length, you might need to prune them after they attain the mature height in about 1-2 years.

Meanwhile, the trailing plant extends up to 30 cm wide under sunlight with partial shade.

Other varieties of Sweet Peas similar to King Edward VII in growth rate include ‘Beaujolais,’ ‘Erewhon,’ ‘Air Warden,’ ‘Prima Ballerina,’ and ‘Swan Lake.’
Grow the King Edward VII seeds in manure rich, slightly acidic to alkaline, well-draining soil for better results.

How to Grow Sweet Peas in Hanging Baskets? 

Seeds are the only medium you can get blooming Sweet Peas at home. 

But, germinating seeds is more laborious than looking out and caring for Sweet Peas.

1. Collecting Hanging Basket

Choose a pot of 12 to 14 inches that is easy and strong to hang on the ceiling and wall, as the vines tend to trail down from a single side.

Get an idea of baskets by looking at the Hanging Pots for Indoors.

You can also make a DIY round container with a strong and short string attached to the top.

Use sphagnum moss and coco coir liner to promote water retention and drainage facility.

2. Preparing the soil 

Use potting mix available in online stores, or make a DIY soil using a potting mix, perlite or peat moss, and coarse sand in a 1:1:1 ratio.

Moreover, add a quarter of organic matter to boost the nutrients for seeds and fill the pot with gravel.

Lastly, put the mix in the hanging pot you have prepared and try to keep the soil moist, not damp. 

3. Sowing Seeds 

Seeds of Sweet Peas have a hard coat making it difficult for the seeds to germinate, so they usually have to be pre-treated.

You can either rub the seeds over sandpaper or soak the seeds for 24 hours if you plan to sow indoors or outdoors in spring.

Meanwhile, pre-treatment is unnecessary for fall sowing as the cold helps break the coat. 

Plant two to three seeds 1-2 inches deep in the soil by maintaining a space of about 4 to 6 inches.

Sow the Pea seeds in late winter or early spring indoors and early spring outdoors to keep the seeds under 55-65º F when germinating.

Germination usually occurs within 2 to 3 weeks and yields beautiful flowers within 75-85 days.
