Why a Pot Is Not a Compromise

A mews courtyard is a gift and a puzzle in equal measure. You get shelter, warmth bouncing off brick, and a suntrap that ripens fruit far better than an exposed garden ever would. What you do not get is a border. Space is measured in paving slabs, and every plant has to earn its patch. That is exactly why containers suit mews living so well: a pot is mobile, it can be moved to chase the sun or tucked against a wall in winter, and it gives you total control over the compost a hungry fruit plant sits in. Grown properly, a dwarf apple in a 45cm pot will crop for fifteen years or more. Grown carelessly, it will sulk, set no fruit, and die back from the roots. The difference is almost entirely down to variety choice, compost, and repotting on a sensible cycle.

Choosing Dwarf Varieties That Behave Themselves

The single most common mistake is buying a lovely garden-centre tree without checking its rootstock. For pots, the rootstock is everything. Look for the plant's ultimate height and spread on the label, and treat anything above 1.8m as too big unless you plan to re-pot into something the size of a half-barrel.

• Apples: Choose M27 (very dwarfing, needs permanent staking) or M9 (dwarfing, the reliable workhorse, roughly 1.5–1.8m). Spur-bearing varieties are far easier in pots than tip-bearers, because you can prune them into a tidy framework. Look for self-fertile or partially self-fertile cultivars so a single tree will crop alone, and if you have room for two, pick varieties from the same or adjacent pollination groups.
• Blueberries: These are the most rewarding patio fruit, provided you never let them near ordinary compost. Two varieties is better than one for cross-pollination and a heavier crop, and dwarf or semi-dwarf cultivars that stay around 60–90cm are ideal. They need lime-free conditions, so rain­water and ericaceous compost are non-negotiable.
• Strawberries: The quickest win of all. Three plants in a 30cm pot, or a planted tower for tighter corners. Summer-fruiting types give one heavy flush; everbearers crop in smaller waves from June to September. Replace plants every three years, as yields fall away sharply after that. Alpine strawberries are worth a pot of their own — they tolerate a little shade, never run wild, and fruit all summer.

Containers, Compost and Drainage

Size matters more than style. A mature dwarf apple wants 35–45 litres; blueberries do best in 30–40 litres, moving up gradually rather than being dumped into an enormous pot straight away. Terracotta looks wonderful in a mews but dries out fast; glazed or frost-proof ceramic holds moisture better, and a light-coloured pot keeps roots cooler in a hot courtyard.

Use a loam-based compost for apples — it is heavier, so the tree does not rock in the wind, and it holds nutrients well. Ericaceous compost, ideally mixed with a little bark or leafmould, is essential for blueberries. Strawberries are unfussy but appreciate grit or perlite for drainage. Always add crocks or a layer of gravel, and raise pots onto feet so water never sits stagnant underneath.

Watering and Feeding Through the Season

In a sheltered courtyard, pots dry out surprisingly quickly, even after rain, because the walls shield them from the shower. Little and often beats a weekly soak. From April to September, check daily with a finger pushed 2cm into the compost. A saucer helps, but empty it after heavy rain so roots are not drowned.

Feed according to the job the plant is doing. In spring, apples and blueberries want a balanced or slightly nitrogen-rich feed to push growth. Once flowers set and fruit begins to swell — usually late June — switch to a high-potassium tomato feed every fortnight. Strawberries follow the same pattern: potassium from flowering onwards makes firmer, sweeter fruit. If blueberry leaves turn yellow between the veins, the compost has drifted alkaline; water with rainwater and give a sequestrated iron tonic.

Repotting and Root Pruning

This is the job that separates thriving pots from tired ones. After two or three years, compost collapses, drainage suffers and roots circle the pot wall, strangling themselves. Every few years, in late winter while the plant is dormant, lift it out, tease away the outer roots with a hand fork, and cut back roughly a third of the root ball with clean secateurs. Shake off as much old compost as you can, then replant into the same pot with fresh compost and firm it in well. Never simply move a pot-bound plant into a bigger pot without root pruning — it will keep circling and never settle.

In the years between repotting, top-dress each March: scrape off the top 3cm of compost and replace it with fresh, which keeps nutrients ticking over without disturbing the roots.

Pests, Winter and the Small Joys

Vine weevil larvae are the container grower's chief enemy, chewing roots unseen until a plant collapses. Biological nematodes watered into the compost in late summer and early autumn keep them in check. Net strawberries against birds, and keep an eye out for aphids on soft apple tips.

In winter, pots freeze harder than open ground. Move them against a sheltered wall, wrap them in bubble wrap or hessian, and raise them onto feet so they drain. Water sparingly but never let them dry out completely. Prune apples into an open, goblet-shaped framework in winter, and take out the oldest blueberry stems from the base every few years to keep the bush productive.

There is something quietly satisfying about stepping out of a small mews door on a July morning, coffee in hand, and picking your own breakfast. A courtyard of pots can do that, provided you give the roots room to breathe and the compost a refresh every so often.
