Filling a garden with plants can be expensive. But choose the best budget plants and you'll find that money can easily be saved rather than splashing out on expensive blooms that won't go the distance.
For biennials you'll want a succession of flowers in spring and summer. And growing from seed will always be cheaper, so start off biennials in trays from May to July and plant out in the autumn.
Annuals are an affordable way to fill containers and plug gaps in your borders. Make successional sowings for a longer display, or choose online mail order plug plants, but be sure to compare prices and delivery charges.
Climbers are great value plants for their incredible vigor and sheer flowering ability the ones we've chosen are because they bloom continuously throughout summer and into autumn.
Then there are grasses and sedges which can be grown for their foliage and smaller size. These like to be divided every few years, which will increase your stocks at no extra cost and therefore they're the perfect choice for your budget garden ideas.
Many perennials will flower for several weeks. To give the best value, we've selected plants that are easy to divide or grow from seed to save you buying flowering plants or pricey plugs.
When it comes to trees and shrubs it’s a false economy to buy larger specimens that may struggle to establish compared to smaller versions.Therefore we've gone for a mix of deciduous and evergreen plants that will perform over a long period.
We've even covered herbs and edibles which will give you much more bang for your buck. Not to mention a selection of house plants which are good investments for being long-lived and self-propagating.
Scroll on for the full list and pick out your favorites.
