Summer weather is just around the corner and bedding plants offer a simple way of adding a pop of colour to your floral border. However, given that most bedding plants are tender, they can not survive harsh conditions such as low temperatures or wet cold spells. This is why gardeners are urged not to plant out their flowers too soon.
Therefore, it is best to keep an eye on the long forecast and make sure you are certain no more frost will arrive before planting your borders out.
If you do wish to bed your plants a little earlier, the experts recommend covering with fleece or cloche.
Sunday Gardener adds: “Knowing if a plant is fully frost hardy or not will also help when selecting plants for the garden.”
Which plants and flowers are suitable for border plants?
According to the RHS, bedding plants are usually chosen from half-hardy annuals, hardy annuals, hardy biennials, half-hardy perennials, half-hardy or tender sub-tropical plants, hardy perennials or shrubs and bulbs.
Half-hardy annuals are plants that complete their lifecycle in one season. These plants tend to be grown from seed indoors and later moved outside.
They can include cosmos, nemesia, marigolds and tobacco plants.
Hardy annuals, such as Alyssum, pot marigolds, Iberia and Limnanthes douglasii, can be sown outdoors directly into the soil and flower in spring.
They are able to withstand frosty spells.
Hardy biennials complete their life cycle in two seasons and include plants such as Alcea (hollyhock), Dianthus (sweet William), Erysimum (wallflower) and Myosotis (forget-me-not).
Half-hardy or tender sub-tropical plants are often used to create a focal point for flower beds. Succulents, for example, can be a great addition.
Hardy perennials add flowers and foliage to your garden right up until the winter months. Some plants of this category include ornamental grasses or Erica (winter-flowering heather).
Bulbs are often scattered alongside biennial bedding plants to add a splash of colour to borders and beds during the early months of the season.
