Garden Checklist: Fall on its way, adjust irrigation

Enjoy the last flush of blooming roses along with the bounty of the fall harvest.
Tasks for this time of year include adjusting the watering systems as weather cools.
Remove and dispose of any fruit and nuts that cling to the tree. Spray hedges and shrubs with water to clean and keep them free of dust to discourage spider mites.
Water citrus being careful not to overwater. Continuously wet soil risks root rot.
When pruning, do not apply any treatments to pruning cuts or other wounds because these materials are ineffective and often are detrimental. Deadhead and shape rosebushes to promote a final fall bloom.
When fertilizing wait two weeks after planting new flowers and vegetables before feeding with organic or complete fertilizer. Add bulb fertilizer to planting hole before planting bulbs.
Planting: This is the best time to plant shrubs and groundcovers. Groundcovers: Carpet bugle (Ajuga), Germander (Teucrium chamaedrys ‘Nanum’). Perennials: Cyclamen, French tarragon (Artemisia dracunculus), cranesbill (Geranium). Before planting winter vegetables, turn a generous amount of compost into the vegetable bed. Fruits and vegetables: garlic, onion sets, lettuce, parsley. Trees, shrubs, vines: Acacia baileyana, strawberry tree (Arbutus ‘Marina’), hawthorn (Crataegus), sago palm (Cycas),  desert willow (Chilopsis linearis). Enjoy now: Annuals and perennials: vinca (Catharanthus), chrysanthemum, dianthus, coneflower (Echinacea), globe amaranth (Gomphrena). Bulbs, corms, tubers: dahlia. Trees, shrubs, vines: pineapple guava (Feijoa), morning glory (Ipomoea), crape myrtle (Lagerstroemia). Fruits and vegetables: almonds, lettuce, melon, nectarines, persimmon.
Fall color: goldenrain tree (Koelreuteria), sweet gum (Liquidambar styraciflua).
Things to ponder: Do not replace vinca with pansies in the same bed due to a soil borne fungal root rot that affects these plants.
