Is Growing Garlic Yourself Actually Worth It?

More than “just plant a clove”

Garlic gets recommended constantly as an easy, low-effort first crop — plant a clove, wait, harvest a bulb. I’ve grown it most years for a decade or more, and that’s broadly true, but “just plant a clove” undersells two real decisions worth getting right before you start: which garlic, and when.

Why supermarket garlic isn’t the shortcut it looks like

Planting a clove from a supermarket bulb is the obvious cheap option. It’s genuinely not recommended: supermarket garlic is often imported, may carry diseases that can persist in soil or a container for future seasons, and isn’t necessarily suited to the UK’s growing conditions in the first place. Named seed garlic from a garden centre or specialist supplier costs meaningfully more, typically £8–12 for two bulbs. But it’s bred and checked specifically for reliable UK cropping, which the cheaper option doesn’t promise.

Hardneck or softneck, and why it’s not just a flavour choice

Hardneck varieties have a stronger, more complex flavour and produce scapes — edible flower stalks that are a genuine bonus harvest in early summer, before the bulb itself is ready. They store for a shorter time than softneck types. Softneck varieties are milder, store for longer, and are the type most commonly sold in shops, which is part of why home-grown hardneck garlic tastes noticeably different from what most people are used to buying.

Timing is the one thing worth getting right

Garlic wants a real cold spell to trigger proper bulb division, which is why it’s planted in autumn (October to December) rather than spring like most vegetables — skipping this by planting in spring instead works, but produces smaller bulbs than an autumn planting does. Harvest for an autumn-planted crop comes the following June or July, which is a long time in the ground for something this low-maintenance — garlic mostly just sits there over winter needing very little from you.

The flavour gap is real, the shortcut isn’t

The flavour difference between home-grown and shop-bought garlic is real and noticeable, not a rounding error — it’s one of the clearest differences I’ve tasted between home-grown and shop-bought of anything I grow. But it depends on starting with real seed garlic, not a supermarket bulb, and on genuinely committing to an autumn planting rather than treating spring as an equivalent substitute. Given how little ongoing attention it needs once planted, the extra few pounds for proper seed garlic is a reasonable trade for a crop that mostly grows itself over winter.
