Garden Maintenance Costa del Sol: The Annual Calendar

What a Costa del Sol garden actually needs, month by month

A garden on the Costa del Sol does not behave like a garden in northern Europe. The climate splits into two stress periods: a long, hot, dry summer from roughly June to September, and a mild but occasionally wet winter that can bring frost inland above 300 metres. Between them sit two shorter windows, spring and autumn, when most of the real work gets done.

Owners who are only here for a few weeks a year tend to visit in summer, see the garden looking green, and assume everything is fine. Often what they are looking at is a garden surviving on irrigation rather than thriving. The system behind those green plants is the thing that needs attention, and you cannot see it from the terrace.

What follows is the full year: what needs doing, when, and what skipping visits actually costs.

Spring: the window that sets up the whole year

March is when the garden starts moving again after winter dormancy. It is also when owners who left the irrigation running on a winter setting discover it has either run too much (waterlogged beds, fungal problems) or not at all (dried-out roots in plants that look fine until, suddenly, they are not).

The first spring visit should include a full irrigation check. Each zone tested, emitters cleared, timer updated for rising temperatures. A drip system that worked fine in October will need a different schedule by May, and a different one again by July. Owners who set a timer in April and leave it untouched through August are usually the ones calling in September about dead planting.

Spring is also weed season. The mild winter rains germinate everything, and weeds not cut before they go to seed in April or May become a much bigger problem in summer. One missed spring visit can double the work in June.

Palm trimming in spring is a decision to make carefully. The processionary moth (procesionaria) is active from roughly February through May. Its nests in palm crowns are hazardous to handle, and some Costa del Sol municipalities require trimming to be done outside this window. The right season is November through January, before the larvae become active. If your palms were not trimmed last winter, wait until the following November rather than trimming in spring and risking a problem.

Summer: keeping things alive, not beautiful

June through September on the Costa del Sol is a survival exercise for most gardens. Daytime temperatures on the coast regularly pass 35 degrees Celsius and climb higher inland. Rainfall is close to zero. The garden's only water source is the irrigation system, and if that system has a fault, plants can die within days.

This is the period when owners abroad are most likely to skip visits. The logic seems reasonable: the garden looked fine when we left in late June, and we will be back in August. But two months without a check is a long time when the system can fail in ways nobody can see remotely.

Common summer failures we see:

• Drip emitters blocked by mineral deposits or debris. Individual plants die while everything around them looks healthy. Easy to fix in May. Expensive to replace in September.
• Timer batteries depleted. Some controllers lose their programme when the battery dies. The irrigation stops, and nothing alerts the owner.
• Pressure drops in the supply. Spanish summer water demand can reduce mains pressure, so drip systems calibrated for normal pressure under-deliver.
• Heat-stressed or diseased plants. Summer humidity plus heat creates conditions for certain fungal problems. Catch them early and it is a treatment. Miss them and it is replacement planting in October.

Fortnightly visits during summer are a minimum. Weekly is better for larger or more complex gardens. The garden service covers irrigation monitoring, plant health checks, dead-heading, and mowing where it applies.

Autumn: the recovery and replanting window

October brings lower temperatures and, usually, the first real rain of the year. This is when the garden can recover from summer stress, and the right moment to replace anything that did not survive.

For owners who plan to sell or let, autumn replanting pays back: gardens that look bare and scorched in late summer recover well if replanted in October and November. Mediterranean species (agapanthus, bougainvillea, rosemary, lavender, plumbago) suit the conditions and will establish over winter, ready for spring. Non-native species that need constant summer irrigation are usually not worth replacing unless the owner specifically wants them.

Autumn is also the right window for palm trimming. November and December are the safest months. The processionary moth has not yet hatched its new generation, and the palms are out of their main growth phase. A good trim removes dead fronds, reduces the load ahead of winter storms, and gives the crown a clean shape for the next year.

Leaf removal matters from November onwards, particularly for properties with deciduous trees or large canopies. Leaves left on a lawn or terrace through winter cause moss and fungal growth underneath.

Winter: less frequent, but not zero

December through February is the quietest garden period on the coast. Growth slows, irrigation demand drops, and most properties need only a monthly visit for general tidying and winter pruning of shrubs and roses.

The irrigation system should be turned down in November. If there is any frost risk at the property's elevation, exposed sections need draining or insulating. Properties above 300 to 400 metres inland can see overnight frosts in January. Most coastal properties below that elevation do not, but it is worth confirming for your specific location.

Winter is also the quietest time for pests and disease, which makes it the moment for the slower work: soil feeding and structural pruning, plus hedge shaping. A garden fed and shaped in winter is easier to manage through the busier spring and summer.

What happens when you skip the dry season

The most common pattern we see runs like this: owner visits in June, garden is fine, owner leaves, no maintenance over summer, owner returns in late August or September. The outcomes vary by garden and by how reliable the irrigation is, but typical findings include:

• Several dead or severely stressed plants, particularly in exposed beds without shade
• An irrigation system that has run on the wrong schedule for six to eight weeks
• Weed growth that has gone from manageable to established
• Near scrubland or where dry organic matter has built up, an elevated fire risk from dead vegetation

Recovery from a neglected summer is rarely quick. Replacing established planting, resetting irrigation infrastructure, and doing the clear-up takes multiple visits. The cost is consistently higher than maintaining through the summer would have been. This is not a hypothetical. It is what we see at the start of autumn, when owners who skipped summer visits book the first service back.

If regular visits are not practical for you, the minimum that works is this: a full system check and handover visit in late May before the heat sets in, then a fortnightly check by someone physically on site through July and August. That does not have to be a full garden service every fortnight. A quick inspection and irrigation confirmation is enough. But it has to be someone who can actually turn a tap and check an emitter.

Booking and what to expect

Every garden visit through SolidMaint follows the same operational standard. The crew arrives within the booked slot, takes before-and-after photos, and submits a written report in your language. The report covers what was done, what was found, and any follow-up recommendations. That record stays in your Property Vault permanently.

For owners who want regular coverage, a recurring subscription is the simplest approach. For specific one-off work, on-demand requests do the job. Current pricing is on the pricing page.

If you are not sure what your garden needs right now, the most useful first step is a single assessment visit. It produces a written report on the current state and a recommended schedule for the year, so you have a baseline and a plan rather than a guess from a few holiday photos.
