The Monthly Villa Garden Maintenance Checklist (The One Professionals Actually Use)

There is a consistent pattern in the villa gardens we are called to rescue. They were beautifully designed once. They had a mature plant palette, a good irrigation system, a hardscape that still looks right. And then maintenance was either left to whoever was cheapest or skipped during a quiet month, and two years later the garden is fighting itself.

The gardens that age gracefully are the ones on a disciplined monthly rotation. Not more work than an inattentive garden — often less, because problems are caught early — but scheduled.

This is the twelve-month checklist we keep on the studio wall. It is a composite of the routines we run on villa commissions in Istanbul, the Turkish coast, and the Gulf, adapted for Mediterranean-climate gardens. Print it, pin it, work through it.

January — the dormant audit

• Full tree audit: photograph every major specimen, note any deadwood, storm damage, or pest concerns
• Structural pruning of mature olives, fruit trees, and deciduous shrubs (see our olive pruning guide)
• Apply winter dormant oil to fruit trees to smother overwintering pests
• Clean and sharpen all pruning tools; replace worn blades
• Inspect and repair irrigation manifolds (hard freezes can crack fittings)

February — the main pruning month

• Complete structural pruning before buds swell (by end of month in Istanbul)
• Prune wisteria, climbing roses, and deciduous shrubs
• Divide overcrowded perennials (hostas, daylilies, ornamental grasses)
• Mulch all beds — 5 to 8 cm of organic mulch before spring weeds germinate
• Apply slow-release fertiliser to trees and shrubs

March — waking the garden

• Remove winter mulches from crown-sensitive plants (iris, peonies)
• First mowing of the lawn when daytime temperatures consistently exceed 12 °C
• Overseed thin lawn patches
• Plant bare-root trees and roses (deadline: mid-month)
• Start hardening off seedlings from greenhouse

April — main planting window

• Plant container-grown trees, shrubs, perennials, and herbs (see our April planting guide)
• Apply balanced spring fertiliser (10-10-10 NPK at half rate)
• Begin regular lawn mowing weekly
• Set up drip irrigation; test every emitter
• Install plant supports and stakes before stems grow

May — pre-summer sweep

• Last safe window for warm-season vegetable planting
• Deadhead spring-flowering perennials
• Check and adjust irrigation schedules as heat increases
• Apply a second round of mulch if the first is thin
• Spray preventative horticultural oil on susceptible plants (roses, citrus)
• Harvest first lettuce, radish, early herbs

June — the transition

• Deadhead early-blooming annuals to encourage second flush
• Trim hedges (box, privet, lavender edging) to shape for summer
• Stake tall perennials before they flop
• Start foliar feeding of container plants weekly
• Monitor for early signs of powdery mildew and treat immediately
• First cherry, apricot harvest

July — hot-weather mode

• Water early morning only — never evening
• Remove water sprouts on olives and fruit trees (see olive pruning guide)
• Pinch back leggy growth on basil, mint, other herbs to keep dense
• Harvest summer fruit continuously — do not let overripe fruit rot on tree (attracts pests)
• Raise mowing height to 6–7 cm to protect lawn roots
• Never fertilise during peak heat

August — survival month

• Water deeply, infrequently — 2 deep soaks per week better than daily shallow
• No pruning, no fertilising, no major transplanting
• Daily inspection of container plants (dry out fast)
• Check mulch depth — top up to 5 cm where weathered down
• Harvest tomatoes, peppers, stone fruit continuously
• Note which plants struggled — they will be candidates for replacement in autumn

September — recovery and preparation

• Deep watering for any plant showing heat stress
• Second round of fertiliser for lawns and flowering perennials
• Begin planning autumn plantings — order trees for November
• Clean up and compost summer annual debris
• Overseed tired lawn areas with cool-season grasses
• Harvest grapes, figs, late tomatoes

October — second planting window

• Plant spring-flowering bulbs (tulip, narcissus, crocus, allium) — critical deadline before soil cools
• Plant balled-and-burlapped trees and large shrubs
• Divide and transplant perennials that declined over summer
• Apply autumn fertiliser to trees and lawn
• Final mowing of warm-season lawns (Bermuda, Zoysia) — lower height to 3–4 cm
• Harvest pomegranate, late pears, winter squash

November — winding down

• Rake and compost fallen leaves (healthy leaves only; diseased go to bin)
• Protect tender plants (citrus, some roses) with burlap or move to sheltered position
• Final irrigation check before winterising
• Drain exposed drip lines in freeze-prone regions
• Plant winter vegetables (garlic, overwintering onions, broad beans)
• Check and reinforce all plant supports before winter storms

December — rest and plan

• Minimal active work — tools down
• Review the year photographically; note successes and failures for next year
• Plan next year's plantings and hardscape additions
• Protect young trees from deer, rabbits, rodents (tree guards, wraps)
• Order seeds and bare-root stock for late-winter delivery
• Take a month's rest — the garden will need you again in January

The three rules behind the calendar

1. Early and often beats late and heavy. A ten-minute weekly walk catches problems that a quarterly visit misses. If you only do one thing, walk the garden weekly with a notebook.

2. Season-matched timing is half the skill. Pruning an olive in April undoes a year of work. Fertilising a lawn in August burns it. The calendar is a tool to prevent expensive mistakes of timing.

3. Quality of labour matters more than quantity. A skilled gardener for two hours a week does more good than an unskilled one for eight. Pay for skill, schedule, and continuity — not for hours.

What NAS provides

Our maintenance contracts across Türkiye, the Gulf, and the Levant run on exactly this calendar, executed by consistent teams who know each garden individually. Each season we send written reports with photographs. Each year we audit and update the plan with the client.

If you have a villa garden that has drifted, or you are setting up maintenance for a new property, send us the site plan on WhatsApp +90 535 422 5227. A real landscape architect will propose a maintenance schedule the same working day.
