Pre-Rooted Sets

Grow bigger, stronger garlic ready to harvest earlier in the season with our pre-rooted garlic sets! Our innovative NEW format is ideal for Autumn planting and for gardeners with small plots.

Do you know why birds like to pull up your freshly planted oning and garlics, it isn't just to see your angry face! No, it is because they are after the earthworms that in turn are attracted to microbes present in the immediate area around the rooting called the Rhizosphere. Microbes feast on the proteins, sugars and dead cells created from the plants roots. However, as these are pre-rooted the birds will find them harder to pull up and should leave them alone. The microbes in turn, provide the plants with essential nutrients and so the cycle continues.

To give you a head start on the growing season, we’ve pre-rooted garlic sets into plug trays, with each cell containing 1-2 sets. Unlike normal sets, which take several weeks to start growing after being planted, these pre-rooted plugs are already rooted and growing when you receive them, ready to plant out. They’ll establish quickly, producing bigger, stronger plants earlier than traditionally planted sets, with less risk of birds or animals pulling out the sets.

Our pre-rooted garlic sets are great for gardeners with small plots who only have space for a few plants and don’t want to waste a big bag of sets. There’s no more waiting to see whether all your sets will sprout – you can already see them growing! And if you missed your chance to plant sets earlier in Autumn, these pre-rooted sets are already ahead and no time is lost.

Plant out as you would normal sets. Any Cells that have 2 sets in, gently tease apart and plant separately
