The Three Top Windowsill Propagator by Garland is a compact and efficient solution for indoor seed sowing and plant propagation, designed specifically to fit neatly on most standard windowsills.

This clever propagator system features three individual high dome propagators housed within a single sturdy base tray. Each section creates its own growing environment, making it easy to sow multiple varieties at once or stagger sowing times for a continuous supply of seedlings. The clear high dome lids provide generous vertical space, making them particularly well suited to taller seedlings and larger cuttings.

The raised domes help retain warmth and humidity, supporting faster and more reliable germination while still allowing plenty of light to reach young plants. This balanced environment helps reduce the risk of fungal issues and encourages strong, upright growth from the earliest stages.

Made from durable injection moulded plastic, the base tray and propagator sections are built for repeated use. The clear lids are lightweight and allow excellent visibility so you can easily monitor progress without disturbing your plants. Apart from the clear lids, the propagator is made using 100% recycled plastic and is fully recyclable at the end of its life.

Ideal for kitchens, conservatories, utility rooms or any bright indoor space, the Three Top Windowsill Propagator is a practical choice for gardeners who want reliable results without the need for a greenhouse. Replacement trays and lids are also available separately, helping extend the life of the system season after season.
