Geranium Plug Plants: A Complete Guide for UK Gardeners
Geraniums are a timeless favourite for British gardens, offering vibrant colour and long-lasting blooms. If you’re looking for an easy and cost-effective way to fill your beds, borders, and containers, geranium plug plants are the perfect solution. In this guide, we’ll explore why they’re so popular, how to plant and care for them, and where to buy the best quality plugs.
Why Choose Geranium Plug Plants?
Affordable and Convenient
Plug plants are small, young plants grown in trays, making them more affordable than mature plants. They’re easy to handle and ideal for gardeners who want to grow large quantities without breaking the bank.
Perfect for Beginners and Experts
Whether you’re new to gardening or a seasoned pro, geranium plugs are simple to plant and maintain. They establish quickly and reward you with stunning blooms throughout summer.
Ideal for Containers and Borders
Geraniums thrive in pots, hanging baskets, and garden borders. Their versatility means you can create vibrant displays on patios, balconies, or in flower beds.
How to Plant Geranium Plug Plants
Preparing Your Soil
Choose well-draining compost enriched with organic matter. Geraniums dislike waterlogged soil, so ensure good drainage to prevent root rot.
Best Time to Plant in the UK
Plant your geranium plugs in late spring after the risk of frost has passed. This gives them time to establish before the summer flowering season.
Step-by-Step Planting Guide
- Gently remove plugs from their tray.
- Plant them in pots or directly into prepared soil.
- Space plugs about 20–30 cm apart for healthy growth.
- Water thoroughly after planting.
Caring for Your Geraniums
Watering and Feeding Tips
Water regularly but avoid overwatering. Feed with a balanced liquid fertiliser every two weeks during the growing season for lush foliage and vibrant blooms.
Pruning for Continuous Blooms
Deadhead spent flowers to encourage new growth. Pinch back stems to maintain a bushy shape and prevent legginess.
Common Problems and Solutions
- Yellowing leaves: Usually caused by overwatering or poor drainage.
