Gardening Tips for October 2018

October in Your Garden...

  • Work in the Garden – Prepare for winter by picking up debris such as fallen fruit and leaves.  When the rains start, debris becomes a home to a host of garden pests, particularly snails and slugs.  In the colder areas of San Diego, mulch around frost sensitive plants.  Secure and trim any trellised plants and re-stake smaller trees.  We can still get some hot, dry Santa Ana winds so take care of tender plants and container plants by shading them and mulching.  Use a micronutrient foliar spray on plants suffering from chlorosis, particularly azaleas, bottlebrush, citrus and gardenia.  Thin tree branches to decrease weight and reduce wind damage.  Prune any dead or diseased limbs.  Winter harden trees and plants by cutting back plants hard, then feeding one last time.  Plants that require winter hardening are generally tender plants and sub-tropicals such as bougainvillea, hibiscus, fuchsias, geraniums and Christmas cactus.  Cut back on your watering and fertilizing schedule. dianthus
  • Bedding Plants – Plant wintering annuals such as calendula, candytuft, chrysanthemums, cyclamen, dianthus, lobelia, nemesia, pansy, penstemon, phlox, Iceland poppy, primrose, snapdragons, stock, sweet alyssum, sweet William, and viola.  Protect from any hot spells by shading and extra watering.
  • Vegetables – Clean up remaining summer vegetables.  Sow seeds of beets, broccoli, cabbage, carrots, cauliflower, celery, kohlrabi, lettuce, mustard greens, peas, radishes and spinach.  Plant asparagus and ever bearing raspberries.  Harvest pumpkins, corn and winter squash.  Break up soil and till with prepared compost and any other necessary amendments.  Pot up all tender herbs to be brought indoors.  Plant garlic, cilantro and parsley in a sunny spot.  Hardier perennial herbs that were started from seed indoors can be brought outside now including chives, lavender, winter marjoram, mint, sage, tarragon and thyme.
  • Fruiting Plants – Now is a great time to plant citrus trees.  Choose from a variety of citrus including grapefruit, lemons, limes, oranges, mandarins, calamondins, kumquats, and tangelos.  Deep water ma Calamondin tree ture citrus trees every three to four weeks as needed.  When watering, keep in mind that citrus have very deep roots, as deep as the tree is tall.  Prune berry vines that bore fruit last year hard.  Tie up new canes. Cut back on watering of deciduous fruit trees to encourage dormancy and do NOT fertilize now since that will encourage growth.
  • Lawns – To increase water and fertilizer infiltration, aerate and dethatch lawns, followed up by adding gypsum. Re-sod any worn spots in lawns that were not seeded last month.  Fertilize one month after installation and every month thereafter throughout the fall, winter, and spring.  Feed cool season grasses such as blue fescue and rye with an all-purpose fertilizer. Also continue to feed warm season grasses such as Bermuda, St. Augustine, and Zoysia for the next couple of months.  Over seed warm season grasses going dormant with annual rye for a lush winter lawn.  Reduce watering depending on weather conditions. Reset the blades on your mower to 1 ½”-2” for fescue lawns.
  • Roses – Plant container roses.  Water once or twice a week as needed.  Fertilize with Gro-Power. Pink Trailing Gazania
  • Some Specific Plants – Plant ground covers now to give roots a chance to establish themselves before spring growth and to help with any erosion concerns.  Fertilize lightly with Gro-Power.

Changing Weather

  • Wind damage can be a problem this month.  Thin tree branches to decrease windage and reduce tree weight.  If the tree is very large or valuable, or has grown over the house or busy traffic area, it would be wise to have it done professionally.
  • A Bermuda grass lawn need not be brown all winter.  Simply sow annual ryegrass into it which germinates quickly and keeps the lawn green all winter.
