Autumn Gardening Guide

Autumn is a fantastic season in the garden. The air is crisp, with warm long days, perfect for the tasks that need doing following the heat of summer.

It's is a great time for sowing a new lawn, planting bulbs, trees and shrubs, and of course planting the vegetable garden for the months ahead.

Autumn to do list

• Autumn is the perfect time for lawn TLC, and to sow a new lawn. Check out our 3 simple steps of lawn care.
• Harvest seeds from last season's crops for use next season. Label them carefully before storing.
• Plant up pots and containers with autumn potted colour.
• Apply Tui Organic Seaweed Plant Tonic every 2-4 weeks to help prevent transplant shock, promote strong growth and keep your garden thriving.

In the vegetable garden

• Replace the lost nutrients from those heavy growing seasons by adding in compost, blood and bone, and sheep pellets. This will provide a healthy new foundation for your autumn and winter crops.
• Keep mounding up celery and leeks.
• Harvest pumpkins and dry well before storing.

• Autumn is an ideal time to plant broccoli, cauliflower, cabbage, beetroot, spinach and Chinese cabbages.
• Plant lettuce early autumn and you can get a good harvest from most lettuce varieties.
• Sow seeds for your winter crops like carrots, swedes, turnips and radish. A good seed raising mix that is light and free draining will ensure your seeds get the best possible start.
