How to Choose the Best Hedging Plants
Hedge plants are used to add to the aesthetics and create privacy. Although many people think they can use any hedge plant, this is not the case. Hedge plants are all different and each has special requirements.

Things to Consider Before Buying Hedge Plants
- Sun Exposure - How much sun will the hedge plants get? Some plants require full sun, while others can tolerate some shade. Before you buy your plants, pay attention to the amount of sunlight the area actually gets.
- Height - Do you need hedging plants that will get really tall? Or are you in need of plants that only get a metre tall? Check to see how tall the plants will get when used as hedging shrubs.
- Width - How wide do the plants get? You will need to know this to determine how far apart to plant them.
- Density - Do you want a hedge that is thick and hearty? Or are you looking for a hedge that is airy? A fuller hedge can add more privacy. They can also be good choices for shaping.
- Shape - Are you looking for hedging plants you can shape? Or do you want plants that have a natural look? Some plants have natural conical, round, or mound shapes. While others can take a bit of work to tame.
- Flowers - Do you want a hedge that flowers? Flowers can add to the beauty of the hedge, and they attract pollinators. However, the petals do fall off creating a mess, and some people are allergic to bees.
- Soil - What type of soil do you have? Hedge plants have special soil requirements. If you plant them in the wrong soil, they can die or look very shabby.
- Time - How quickly do you need your hedge to become established? Some plants can grow rather quickly. While some can take years to reach full size.
- Maintenance - How much maintenance do the hedging plants require? If you love getting outside and working in your garden, you may not mind performing regular pruning, watering, and fertilising. If you do not like garden work or do not have the time to do it, look for plants that demand very little of your time.
- Native Plants - Another thing you will want to think about is whether you want native plants. Just because the hedge plants will grow in your area does not necessarily mean they are native to your area.
- Pests & Diseases - Garden hedges are susceptible to pests and diseases. It is important to know what the plants are vulnerable to. This way you can treat the plants before they are affected.
- Location - Where do you want to install the garden hedges? Are you positive the area is on your property? You do not want to plant a hedge only to start an argument with your neighbours. You also need to know where any electrical lines and other utility lines are located.
- Cost - Hedging plants can vary in price. And the more you need, the more you will have to pay. Always sketch out your plant and determine the exact number of plants you need. Remember, plants grow to different widths. So, you will have to determine how closely they need to be placed together.
