Spring Awakening: First Jobs for Peninsula Gardeners
There’s a moment in early September when everything shifts. The Magnolias bloom, the roses push out red new growth, and the soil starts warming up. After months of dormancy, the garden wakes up fast — and there’s plenty to do.
Feed Everything
Spring is when your garden is hungriest. All that new growth needs fuel, and the soil has been slowly depleted over winter.
Roses — give them a good feed as soon as you see new growth emerging. A complete organic fertiliser, a handful of blood and bone, and a sprinkle of potash around the base of each bush. Water in well. Repeat monthly through to March.
Fruit trees — feed with a balanced organic fertiliser. Citrus especially need a good spring feed — they’re about to put energy into flowering and fruit set.
Everything else — a general purpose organic fertiliser spread over garden beds, watered in, does the job. Don’t forget potted plants — they’ve been sitting in depleted potting mix all winter.
Get on Top of Weeds Early
September weeds are small and easy to pull. October weeds are a nightmare. Get out there early and pull everything while the soil is moist and roots come up easily.
This is also the time to refresh mulch if it’s thinned over winter. A thick mulch layer now prevents the worst of the spring and summer weed explosion.
Plant Warm-Season Performers
Once the risk of heavy frost has passed (usually mid-September on the Peninsula, though bayside areas are often frost-free), you can start planting warm-season annuals and perennials:
- Annuals — petunias, marigolds, zinnias, cosmos. Wait until late September or October for these.
- Perennials — Echinacea, rudbeckia, penstemons, and ornamental grasses can go in now.
- Herbs — basil, tomatoes, and other warm-season edibles need to wait until October when soil has properly warmed. But parsley, chives, and thyme can go in now.
Check Your Irrigation
Before the dry months hit, make sure your drip systems and timers are working. Replace any blocked drippers, check connections, and run a test cycle. It’s much easier to fix irrigation in September’s mild weather than in the panic of a January heatwave.
If you don’t have irrigation and you’re relying on hand watering, consider getting a simple drip system installed before summer. It doesn’t have to be expensive, and it’s the single best investment for keeping a Peninsula garden alive through summer.
Divide and Conquer
Spring is the ideal time to divide overgrown perennials. Agapanthus, daylilies, ornamental grasses, and native flax lilies can all be dug up, split, and replanted. You’ll get multiple plants for free and rejuvenate clumps that have stopped flowering well.
Dig the whole clump, use a sharp spade to split it into sections (each with roots and shoots), replant at the same depth, and water in with seaweed solution.
Enjoy It
Spring on the Peninsula is genuinely special. The combination of mild temperatures, longer days, and the whole garden bursting into life is the payoff for all that winter work. Take a moment to actually sit in the garden and enjoy it before summer’s maintenance kicks in.
