Growing Sweet Pea
Growing and caring for Sweet Peas is really easy. They can be grown by both novice and experienced gardeners. As long as you provide your Sweet Pea flowers with their ideal growing conditions, they will thrive and fill your outdoor space with vibrant colours and a seductive fragrance.
First of all, make sure that you grow them in full sun. However, if you live in a warmer climate where the full sun could cause sunburns to the plants, it’s best to keep them in a spot of your garden where they receive partial sun only. It’s particularly important to protect your Sweet Peas from sunlight in the heat of the afternoon. So, depending on the climate in your area, you should choose a place in your outdoor space where the plants get enough sunlight to thrive, but not too much.
In spring and early summer, during the growing season of Sweet Peas, it is best to help your flowers grow happy and healthy with some feeding. We recommend feeding your Sweet Peas monthly with a fertilizer that is high in potassium. For example, you can use a tomato fertilizer. Adding a little bit of blood meal to the soil is also a way to help the stems of the plant grow long and be sustainable enough for cutting.
Pruning is a joy rather than a responsibility when it comes to Sweet Peas. That’s because cutting flowers benefits both you and your plants. As your Sweet Peas start blooming, the more you cut the flowers to use them in your floral arrangements, the more blooms you will get. So, you can always bring some bouquets indoors without worrying that there will be some unattractive gaps in your garden. Also, keep in mind to deadhead the spent flowers because this will encourage continued blooming.
Planting Sweet Pea
When it comes to planting Sweet Peas, there are also a few essential things that you should consider, including the right time to plant seedlings, the best spot in your garden, and the preferred type of soil for these flowers to thrive.
First things first, you should plant your Sweet Pea seedlings outside after the last spring frost. It is essential for the ground to be warm to about 50°F (10°C), and it should also be dry. Prior to planting, it will help if you soak the seeds in warm water for 24 hours to soften the seed coat. Another way to help the seeds germinate prior to planting is to nick them with a file or a sharp knife. This will make it easier for the water to penetrate the seed, which is essential for germination.
Next, make sure that you choose the right spot to plant your future Sweet Peas. More precisely, be sure to select a location in your outdoor space where the plants will get enough sunlight to thrive.
In terms of soil preparation, you should work in a 2 inch (5 cm) layer of compost to ensure that the soil is fertile enough and provides good drainage.
If the temperatures and weather conditions in your area aren’t ideal for growing Sweet Peas outdoors, the good news is that you can also grow these flowers in pots. Just keep in mind the same light, soil, and water needs.
Watering Sweet Pea
Sweet Pea won’t need much of your attention when it comes to water needs. This flower rarely needs to be watered more than once a week. However, how often you need to water it will also depend on the climate in your area.
Sweep Peas don’t fancy hot weather, and when they do have to survive scorching temperatures, they prefer to have moist soil to help them out. So, during the summer months, make sure to water them regularly so that the soil is always slightly moist.
Avoid overwatering because it may lead to root rot. Root rot is a common problem among pea plants. A sign of root rot can be the colour yellow at the base of the plants and wither stems.
Another thing you should avoid is watering your flowers late in the day because this will make the plants prone to scorching.
Propagating Sweet Pea
There are two options to have more Sweet Peas in your outdoor space: propagating them via seeds or cuttings. Propagating these plants via seeds is explained in the planting section, so we’ll focus on propagating via cuttings.
To propagate your Sweet Peas via cuttings use a sharp pair of clean scissors to cut a 5-inch piece of the stem just above a pair of leaves. Next, place the cutting into liquid rooting hormone solution for just a few seconds, and then place it in water. Wait for the rooting system to make its appearance, and then you can plant your newest Sweet Pea in the ground.
Sweet Peas are lovely plants to have around, both in your home and garden. These flowers make your garden pollinator-friendly, they smell absolutely amazing, and they fill your outdoor space with stunning colours. Plus, above all, they are incredibly easy to care for.
