Spring yard cleanup in San Diego happens in two waves: March through early April for the first push, then May for the final touches before summer heat takes over. The checklist is short but specific to coastal and inland San Diego: clearing winter damage, getting irrigation running again, refreshing mulch, and pruning growth that outran itself during the mild winter. Unlike national spring-cleanup guides written for the Midwest and Northeast, San Diego spring work is about preparing for drought, not rain. Here’s what actually needs doing, when to do it, and what you can skip.
When to do spring cleanup in San Diego
The timing is tighter than most regions. San Diego’s winter is mild, and by March the rain stops and heat begins climbing. A yard left unprepped in April can be heat-stressed by June.
Late February or early March is the window for winter-damage assessment and pruning. That’s when you can see which branches died back over the cold snaps (usually just one or two in San Diego), what frost-tender plants got hit, and what needs cutting back hard. By late March, new growth is visible and plants are waking up. Pruning them at that moment, before they’ve spent energy on growth you’re about to remove, wastes less of the plant’s resources.
Mid to late April is the final pass: a week or two after the last pruning, once new growth is established, you’ll see what needs fertilizer, what mulch needs refreshing, and what irrigation lines are running dirty or slow after sitting idle since November.
Waiting past mid-April means you’re pruning in heat, plants recover slower, and you’re moving mulch and refreshing beds when summer is already applying pressure. Mid-May is genuinely too late unless the job is small. Most landscaping companies in San Diego schedule spring cleanup work to finish by the end of April, not because of rain (we’re past that), but because the heat window is tight.
The essential spring cleanup checklist
Three tasks cover 95% of what spring cleanup actually is in San Diego: pruning, irrigation check, and mulch refresh.
Prune back winter-damaged wood and overgrown branches. San Diego’s mild winters mean most plants don’t die entirely; they get tip-burned or branch-killed from the occasional hard frost (2023, 2024). Cut back dead wood from roses, Mexican sage, germander, and any tender shrubs. The rule is simple: if a branch is brown and brittle, it’s dead. If it’s green under the bark when you scratch it, leave it. On drought-tolerant shrubs like coyote brush, California lilac, and toyon, cut back about 1/3 of the height to open up the plant and force branching. Don’t shear it into a ball; thin it to let light and air in. This work takes 2-6 hours for a typical residential yard, depending on how much overgrowth happened over the mild winter.
Check and clean irrigation lines. Winter irrigation stops in November. By March, the lines are full of sediment and algae. Run each zone and listen for pressure and flow. If a drip line is trickling instead of pulsing, or a spray head is spitting, the filter is probably clogged. A 15-minute filter clean-out at the valve or at the timer can fix most of it. If a section of drip line is broken or kinked, this is the moment to replace it before summer watering starts. Broken or clogged irrigation isn’t just a small leak; it’s the difference between a plant thriving and dying hard in July heat. This is also when irrigation repair in San Diego crews get busiest; getting ahead in April beats waiting until June when a plant has already dropped leaves.
Refresh mulch, edge beds, and prep for weed control. Winter rains break down mulch and compact it. Pull back the mulch layer, see what’s underneath (algae and bare soil are both red flags), edge the bed lines crisply, and add 2-3 inches of fresh mulch. Fresh mulch suppresses early spring weeds before they get established, keeps soil cooler as May heat arrives, and signals to the eye that the yard is tended. On a typical 1000 to 1500 square foot suburban lot, mulch refresh takes 3-4 hours for a crew and costs $300 to $800 depending on how thick it was left.
Pruning specifics by plant type
Deciduous trees and shrubs: Cut back any winter-killed tips. On roses and spring-flowering shrubs like lilacs (which are rare in San Diego but show up on coastal properties), wait until late April and prune just after bloom, not now. On summer-bloomers like crape myrtle and butterfly bush, prune now while they’re still dormant; you’ll get bigger flowers. Open up the canopy by removing crossing branches and the interior dead wood.
Evergreen shrubs and coyotes: These get trimmed by 1/3 in late March while they’re still mostly dormant but showing green tips. Cut to a natural shape. Don’t shear them square; plants look better and perform better when they keep their character. Coyote brush (Baccharis), California lilac (Ceanothus), and toyon grow fast in our mild winters, and cutting back hard now prevents them from getting 8 feet tall and woody by August.
Drought-tolerant shrubs and groundcovers: Trim dead tips and any weather-damaged branches. Most drought-tolerant plants need light pruning, not heavy cutting. Overproune them and they sulk all summer. Touching them back 15-20% is enough.
Grasses and ornamental perennials: Cut back dormant ornamental grasses in late February or early March before they break dormancy. Wait later and you risk cutting off new growth. Cut to 4-6 inches above the ground. For perennials that stay somewhat evergreen (sage, germander), just remove dead or damaged material and shape lightly.
Hedges and privacy screens: Late March through early April is the time. One heavy cut now, removing 20-30% of the growth, beats two lighter cuts later. Open hedge trimming service in San Diego schedules fill up by mid-April, so book early if you want the work done before May.
What spring cleanup typically costs
Most homeowners group spring cleanup into one of two tiers.
Light cleanup (pruning dead wood only, no mulch refresh): 2-4 hours labor, $300 to $600.
Full seasonal cleanup (pruning, mulch refresh, irrigation check, edging): 6-10 hours labor plus materials, $800 to $2,000. The range depends on lot size, how overgrown the winter left things, and whether mulch color change triggers a full refresh or a top-up.
Many landscaping companies in San Diego bundle spring cleanup as a seasonal service package, especially for customers with regular maintenance. Bundling costs less than booking individual tasks separately.
When to call in a professional
Spring cleanup is an afternoon’s work if you’re comfortable on a ladder and have basic pruning skills. Call a crew if any of these apply: branches are higher than a step ladder reaches safely; you have overgrown hedges that haven’t been shaped in years; the irrigation is more complex than a single timer and a few drip zones; or you’re not sure what’s dead versus dormant and don’t want to risk cutting back a valuable plant.
A skilled crew can clean up a typical residential lot in a single day or split over two visits. The second visit, about 3-4 weeks later, is when you inspect the new growth, refresh mulch one more time if needed, and make final adjustments.
San Diego spring cleanup frequently asked questions
Q: Is spring cleanup the same as fall cleanup? A: No. Fall cleanup in San Diego is about clearing summer debris, preparing for winter watering, and overseeding any turf. Spring cleanup is about removing winter damage and prepping for dry months. The focus is opposite. Fall is lighter work; spring is heavier on pruning.
Q: Should I fertilize during spring cleanup? A: Not immediately. Wait until late April once new growth is 2-3 inches long and strong. Fertilizing bare branches in March can burn the plant. Late April and May fertilizing supports summer growth when the plant can actually use the nutrients. For drought-tolerant plants, one application in May usually carries them through summer.
Q: Can I compost the branches I prune? A: Green branches and leaves, yes. Wood that’s thicker than a pencil takes months to break down. Most folks chip and mulch the larger stuff or haul it away. San Diego has a few chipping services that’ll take brush at low cost if you’re bulk clearing.
Q: How often should I trim hedges? A: One hard cut per year in late March covers most of it. Some fast-growing hedges (privet, laurel) might need a light shaping in late July too. Most San Diego drought-tolerant hedges get by on one annual pruning.
Q: When should irrigation work start if I’m having lines replaced? A: Now through early May. June and July backlogs are real. If you know lines need work, book in March and April so the work is done before summer testing starts.
Spring cleanup is short work in San Diego because our spring is short. You’ve got about 8 weeks from March 1 through April 30 to move from winter into summer-ready mode. Getting the work done by late April means the yard isn’t carrying winter damage or water-waste into the hot months. If you’re handling it yourself, hit the pruning first, then irrigation, then mulch. If you’re calling in a crew, seasonal cleanup service in San Diego crews book up by mid-April, so book early March to get on the schedule before the rush.
