Continue to set out edible seedlings, like onions or garlic for next year’s harvest. Sow annual seeds, like wildflowers, in a sunny spot for the best show in spring.
If you’re interested in ornamental varieties, plant anything that is not frost-sensitive, including sweet peas, ground covers, shrubs, trees, vines, perennials and natives.
Keep control of slugs and snails with bait containing iron phosphate, which is safer on edible crops and around children, pets and wildlife. Don’t forget about your lawn! October is the time to dethatch, aerate and fertilize your grass.
For vegetable beds, double-dig them by loosing the soil to a depth of 24 inches and adding compost.
If the rain has begun, check for areas of standing water because this is where mosquitoes will hang out. If no rain yet, continue to irrigate.
Keep tidying to reduce the debris that harbors insects and disease over winter. Apply copper or other recommended controls if you see brown rot or citrus blast on your citrus trees.
