Autumn in

Autumn in the garden - April

Autumn is nature's planting time as the soils are warm and moist. Plants have the winter to settle their roots into the soil ready to flourish in spring, so there's plenty of options to plant in April.

Tomatoes, capsicums and chillies will be coming to an end in cooler parts of the country, where the nights are beginning to draw in and the earliest frosts may start to appear. In warm regions, these crops will last another couple of months.

As you harvest the last summer crops April is the perfect time to plant your patch with winter staples including broccoli, cabbage, celery and silverbeet. Freshen the flower garden with pansies and polyanthus and don't forget the Kiwi favourite of feijoas in the fruit garden!

Harvest time is from seedling planting to harvest. For seeds, depending on variety, it will take an extra 6-8 weeks from germination to planting.

Maintenance

Dig in Tui Compost and Tui Sheep Pellets before planting to replenish nutrients used by previous crops. Compost is also an excellent water saver.
Beans - tie up floppy plants, and keep them well watered - they should keep producing for another month or so.
Brussels sprouts - stake taller plants to prevent them from falling over.
Carrots - thin rows of carrots to ensure the roots develop evenly.
Sweetcorn - pull out plants once they have finished, and add the stems to the compost heap.
Tomatoes - these can be left on the plant to ripen if the plants are still looking healthy enough. Otherwise you can pull the plants out and leave any green fruits on a windowsill to ripen in the sun (this may take a few weeks).
Feed established plants once a month with Tui Organic Seaweed Plant Tonic.
Lay Tui Quash to control slugs and snails, and spray aphids and whitefly if they are still a problem.
