How to Plant Gladioli in Pots UK

If you are looking to add a dash of colour and elegance to your garden or deck, planting gladioli in pots can be an excellent choice. This gorgeous flowering plant is easy to grow and can bloom for several weeks with a small amount of care. In this article, we will discuss the steps to plant gladioli in pots in the UK. So let us get started!

Choose the Right Pots

The first step to planting gladioli in pots is to choose the right containers. The pots should be at least 12 inches deep and 8 inches wide, with drainage holes at the bottom. Ensure that the pots you select are sturdy and can support the weight of the gladioli. The ideal choice for outdoor gladioli containers in the UK is clay pots that can withstand British weather better than other materials. Before planting, soak the pots for at least 30 minutes to hydrate them deeply.

Prepare the Soil

Next, you need to prepare the soil for planting the gladioli in pots. Gladioli prefer well-draining soil, which is fertile and rich in humus. Mix high-quality potting soil with perlite or sand to enhance drainage. You can also add a slow-release fertiliser to the soil to provide essential nutrients to the corms. Fill the pot 2/3 of the way with the prepared soil mixture.

Plant the Corms

Now it's time to plant the gladioli corms! Place each corm (pointy-side up) approximately six inches apart on top of the soil in the pot. The corms should be covered with two to three inches of soil, leaving about an inch of space from the top of the container to allow for watering. Once the corms are planted, water the pot immediately to hydrate the soil around the corms.

Watering

Watering is essential for the healthy growth of gladioli in pots. It is best to water the soil in the pot deeply and continuously to keep it moist, but not waterlogged. Check the soil moisture level regularly, especially during dry spells, and make sure the soil isn't drying out completely. Too much water, on the other hand, can contribute to the corms rotting, so ensure that the drainage holes in the pot are functioning correctly.

Feed the Gladioli

To help your gladioli grow and bloom to their full potential, it is essential to fertilize them regularly. Add a water-soluble fertiliser to the soil once or twice a month, following the manufacturer's instructions. Alternatively, you can add a slow-release fertiliser to the soil mixture while planting the corms. Gladioli also benefit from a sprinkling of bone meal on the soil surface, which provides slow-release phosphorous essential for the flower's growth.

Conclusion

Planting gladioli in pots can be a delightful addition to your outdoor space, offering a burst of colour and beauty. By choosing the right pots, preparing the soil, planting the corms, watering, and fertilizing the plants, you can enjoy these lovely flowers throughout the summer.
