This is the time now for removing and dead heading all the summer flowering plants as well as cutting dead plant matter and overgrowth. You want to look at planting your Winter and Spring flowering bulbs before the end of this month.
Use compost and bone meal in the soil mixture when planting, as well as flower bulb food after planting. Good watering is essential at this time to ensure growth and survival until Spring. Remember to change your irrigation start times to later in the morning or earlier in the afternoon as it is better to water during warmer parts of the day to avoid any frost damage.
All thinning out & dividing should also be done now, as this will ensure more room for new growth to take place after Winter. A composting plan should be thought of and applied during the Winter months. It provides the nutrition and soil replenishment required to keep all plants, flowers, shrubs and trees happy. It is a good time to start a compost heap with all the leaves falling, but remember this needs the maintenance of watering, cleaning, fertilizing and layering. Some hard work is involved in the creation of a proper weed-free compost heap that will benefit your garden.

Cut the lawn a few more times before it gets really cold and remove all dead thatch from your lawn by trimming a little lower with the lawnmower.
This is an ideal time to plant roses, shrubs and trees as their roots will be well established by Spring. Hedge planting and pruning should also be carried out, making it easier to create the desired shape prior to the growth in the Summer months.
