  • Have your indoor plants grown too large for their pots? Repot now to acclimate them through the fall.
  • It’s time to start planning your fall vegetable garden! Broccoli, cabbage, lettuce, celery, kale, collards, peas, and chard can be planted now in the West Bay. Wait until September in the East Bay.
  • Select and plant fall blooming perennials: asters, Rudbeckia, Japanese anemone, and salvia.
  • Don’t forget to feed vegetables and flowers with a steady-release fertilizer such as E.B. Stone Organics All Purpose Plant Food.
  • Make sure all tall and vining vegetables are supported by cages, stakes, or trellises to avoid crop loss.
  • Time to summer–prune fruit trees to control height, maintain shape and eliminate suckers. Stop by Sloat Garden Center for a good pair of high quality loppers or gloves.
  • Choose drought tolerant plants that attract butterflies! We have a large selection in our stores. Remember to plant some for nectar like lantana (adults) and some for feeding like native milkweed, Ceanothus, Buckwheat or dill (caterpillars).
  • Feed container plantings with Maxsea. Replace spent plants with something new to keep them fresh. Company’s coming!
  • Mulch vegetables and flower beds now to conserve moisture. Use Hydretain on lawns, beds, and in containers to reduce your need to water.
  • Check your mature plants to be sure they are not water-stressed. Your 30+ year old plants are valuable!
  • Check Brugmansia, Lantana, tomato and Verbena for whitefly. Put out yellow sticky traps to monitor. Use organic Rosemary Systemic 209 to control.
  • Remove runners from strawberries to promote buds for next year, and to have a stronger mother plant. Then, plant rooted runners.
  • Plan out your vegetable garden for crop rotation to avoid re-planting the same types of plants in the same area two seasons in a row.
  • Be pro-active about insects. To reduce the number of flies: remove pet waste and fallen fruit from the ground. For fleas: use nematodes in outside breeding areas.
  • Time to cut back tropical milkweed (Asclepias curassavica) in your garden to encourage Monarch migration. Cut plants back to 6” and strip foliage.
