Gardening is about finding the right combination of fertile soil, sunlight and water to make your plants thrive.

The start of the new year is a great time to focus on gardening. While most think January is not a time for this, planning a garden now allows ample time for finding the right plants and getting a good line on soil, mulch, and all the other stuff that will make the garden more of a success.

For those vowing to grow a garden this year, it’s worth taking this Express.co.uk gardening quiz to see if you need to expand your knowledge of growing plants.

One particular topic this quiz tests on is plant fertiliser. Fertilisers are used to improve plant growth.

The faster growing the plant, the more it will benefit from the application of fertiliser.

For those who have healthy soil, it is often not necessary to use fertilisers, but using them may produce a showier display of blooms or a higher yield of produce from edible crops.

One particular plant that benefits from fertiliser are roses. Feeding your roses will encourage strong, healthy growth and abundant flowering.

To perform their best, roses need a continuous source of nutrients throughout the growing season. Healthy roses not only bloom better, they are better able to withstand insect and disease problems.

It’s a relatively quick and simple task, yet is one of the most beneficial jobs you can do to ensure that your roses are at their most healthy and floriferous when summer rolls around.

Another topic covered in the quiz is deadheading. This task is done to keep plants looking attractive and encourage more blooms, whether in beds and borders, containers or hanging baskets.

While some plants don’t need deadheading, for some plants like roses and hydrangeas, it is crucial.
