Chill Tulip bulbs in the fridge before planting in May.



Liquid feed fortnightly, Thrive Liquid Houseplant for flowering plants and Nitrosol for foliage plants.

Start to reduce watering as the weather cools down, especially for plants such as aglaonema, yucca, dracaena and dieffenbachia.



Take tip cuttings of soft stemmed plants like coleus and impatiens.

Take semi-hardwood cuttings of plants like fuschia, roses and hydrangea.

Citrus trees, azaleas, roses, rhododendrons and camellias should receive an autumn dressing of fertiliser.

Trim hedges to allow some growth before winter sets in.

Once roses have finished flowering spray them with copper oxychloride to prevent foliage and stem diseases.

Divide perennials like michaelmas daisies, astilbes and hellebores.

This is the best month to sow new lawns. Prepare the soil first, spraying for weeds and adding some lawn fertilizer.

Start planting trees and shrubs.

Be careful with watering as over watering at this stage can encourage fungal disease.
