Container planting is a great way to add colour and interest to any garden, no matter the location or size! You can easily switch up your containers with the seasons – or whenever you fancy a change. There are a few things to remember with container plants that will help you get the best out of them, but once you’ve got these tips in your knowledge bank, you’ll be a container whizz!
Things to remember when planting containers
Here are a few tips to help you get the best out of your container plants:
- You don’t just have to plant one plant – or even one species or variety – per container. Try making a statement with different heights, textures and colours!
- Choose your container wisely. Plastic pots are affordable but can be broken if they are too thin; they can also cause drying out in summer. Some terracotta containers are not frost-proof and can shatter in winter, so opt for frost-proof if possible! Concrete containers are attractive and very durable, but some contain high amounts of lime which can seep into the soil and cause a high pH balance (which some plants really don’t like!). Do your research, and find your perfect container!
- Choose a container with drainage holes to avoid waterlogging. However, if it doesn’t have holes, you can either carefully make some using a drill, or place broken terracotta pot pieces or pebbles in the bottom to help with drainage.
- Pots can dry out in summer, but you can add water-retaining granules to help keep moisture levels up if this becomes a problem.
- Leave a gap of around one inch between the surface of the soil and the lip of the container – this will allow you to water well without soil falling out over the sides.
How to plant the best containers: Step by step
I’ve created a handy guide for container planting using Thompson & Morgan’s Glimmer Impatiens Double Collection as my plant of choice.
If you find this guide helpful, please feel free to share my Pinterest pin below to help spread the information!
Container planting guide
- Use a container that’s at least 12 inches in diameter. That way, the plants won’t dry out as quickly and you’ll ultimately use less water (great for your water bill – great for the environment!).
- Use a quality compost. This will provide better results and help retain more moisture too.Â
- Add a quality fertiliser. I’ve used Incredibloom, which is an all-round fertiliser that guarantees your plants will be fed the right nutrients. This is a controlled release fertiliser, which releases only as the weather warms up; much better and no risk of burning your plants. It also helps you grow up to four times more flowers!
- Planting 9cm plants means quicker flowering. Ease the plants out of their pots, always handling by the leaves so as not to damage the stems or any flowers.
- Reduce marks on the patio, and help water drain away, with Pot Mates – simple rings which raise your pot slightly off the ground. Water plants well until established.
