In case you’re wondering, the United States Department of Agriculture (USDA) established these “hardiness zones” to identify various geographical locales based on the specific climates that one can usually experience in these localities. In other words, these hardiness zones aren’t just complex agricultural terms but are an essential tool in determining the kinds of plants that will best grow in any particular area.

What Are The Key Planting Times For Seasonal Flowers

If you want to make sure that you’ll have the flower garden of your dreams within this year, you’ll need to learn about your zone in Great Britain, find your area’s most appropriate plants, and focus on cultivating these plants.

However, if you want to put in flowers that are already in bloom, the best time to do so is during late spring, midsummer, and early winter.


What Kinds Of Flowers Can I Plant In the UK?

Among the best blooms that you can plant in the UK are pansies, calendulas, snapdragons, sweet peas, stock, Johnny-jump-ups, violas, Gloriosa daisy, larkspur, California poppies, nigella, schizanthus, primroses, nemesia, cyclamen,  petunias, calibrachoas, marigolds, sunflowers, moss rose, asters, verbena, zinnias, sweet alyssum, lobelia, borage, Chinese pinks, and the paludosum daisy, Madagascar periwinkle, cosmos, coleus, dahlias, salvia, and nasturtiums.

Borage is another plant that produces flowers any time of the year, freely reseeds all over the yard, and draws bees that naturally pollinate and enhance the quality and the quantity of the flowers you’ll grow.

You’ll be able to see your Chinese pinks bloom every season and the hummingbirds near them. In case you’re not aware, hummingbirds are fantastic to have in your garden because aside from feeding on the flowers’ nectar, they also love to eat pesky pests that include aphids and wasps, mosquitoes, beetles, and ants.

Significant Advantages Of Polytunnel Gardening

Knowing when to plant flowers in the UK is as easy as setting up your own polytunnel, also know as polytunnel. It’s also one of the best decisions you could ever make because aside from protecting your plants from harsh elements and pests, it also allows them to experience extended growing seasons while you get to save energy and more planting options. It doesn’t matter if gardening is your profession or your pastime – you’ll thank yourself for growing your plants in a polytunnel. If you’re still on the fence about investing in a polytunnel, check out the significant advantages of polytunnel gardening to help you make an intelligent decision.


Extended growing season

 Since a polytunnel is a controlled environment where you can maintain consistent temperatures and growing conditions, you can be sure that your plants won’t be put at risk. For this reason, your plants will be able to enjoy longer growing seasons than possible.


Protection from harsh elements

With a polytunnel to provide a layer of protection to your delicate plants, you’ll be able to shield them from unseasonal temperature swings and other harsh weather conditions. Furthermore, the polytunnel works to diffuse the sunlight while it ensures adequate ventilation inside the structure.


A wide variety of plant options

Are you planning to grow warm-season and exotic flowers that one can usually find in your local area? If you decide to invest in a polytunnel, you don’t have to know when to plant flowers in the UK because, unlike traditional outdoor gardens, polytunnels can trap the sun’s heat inside them. This allows it to provide your warm-season and exotic plants with a much warmer environment.

However, you’ll need to fully understand the unique conditions that each of your plants requires to thrive. Thankfully, polytunnel gardening allows you to control the environment so that you can produce the harvest that you’ve been hoping to reap.


You can create the best growing environment

As previously mentioned, polytunnel gardening makes it easier for you to create the ideal growing environment for your vegetables, herbs, or flowers. Since the enclosure allows you to control the amount of light, shade, and moisture that your plants need, your chances of producing a bountiful harvest are greater than those who do traditional outdoor gardening.

Did you know that a ladybug is capable of eating about 5,000 aphids within its lifetime? You can keep the ladybugs, bumblebees, and other insects that are beneficial to your plants inside the polytunnel. In contrast, you keep plant killers such as moles, squirrels, deer, aphids, and caterpillars outside.


You can save energy

One of the best ways to go green is to set up your polytunnel. Polytunnel gardening allows you to recycle water through a feedwater solution that addresses multiple growing cycles as it flows throughout the enclosure.

Furthermore, you can also choose to use a special boiler system to expel CO² while maintaining the optimal temperature inside the enclosure. The CO² that one removes from the system will serve as a natural fertiliser that nourishes the growing plants.

Lastly, since polytunnel gardening allows you to keep beneficial insects inside, you can reduce the need for harmful chemicals, as well as pesticides.
