March is often a time of seasonal change in the garden, and there’s heaps to get your teeth (or trowel!) into. Here’s a selection of jobs to focus on now.
- Prepare garden beds and pots for spring bulbs. Buy the bulbs as soon as you see them on sale, but don’t plant them until the soil is cool.
- Strengthen plants by regularly watering them with liquid seaweed, but remember that seaweed isn’t a substitute for an NPK-based fertiliser.
- Plant evergreen shrubs to give them time to establish before the cold weather arrives.
- Continue removing dead flowers and seed heads from dahlia plants to promote more flowering.
- Reduce watering of your indoor plants gradually as the temperature cools and their growth slows.
- Start introducing sun-loving pot plants to more sunshine if they’ve spent summer protected in shade.
- Cut back pelargoniums if they haven’t been trimmed since spring.
- Tidy kangaroo paws by pulling off dead leaves and cutting down flower stems that have finished blooming.
- Sow sweet peas in soil that has been improved with added compost.
- Take note of autumn trees, shrubs and vines that colour well near you.
