What am I Buying?

Plug plants are small, young plants grown in cell trays. Even the largest plug plants, described as extra-large or jumbo, are still small plants from cell trays and not established plants. Plug plants can be great value compared to buying more established plants however they may need some extra care to get them started.
We also offer our range of plants in larger sizes which gives the option to choose premium plants at a more advanced stage over the cost saving of buying plug plants. Please visit our shop for our full list of plants currently in stock.

Caring for Plug Plants

We recommend starting plug plants in a small pot and not planting directly into open ground or large pots/planters. You will want a plant pot roughly the size of a tea mug, commonly referred to as 7cm or 9cm pots. Ensure the pot has plenty of holes underneath and preferably over two tiers for even better drainage.


* Fill the pots to just below the rim with a good quality multi-purpose potting compost.

* Place the plant into the compost but avoid pressing down too much, a little shake can help ensure there aren't any major air pockets.

* Ensure you water thoroughly, however, it is vital that the compost is allowed to dry down before watering again. It is the drying down of the compost that will encourage faster root growth for most plants.

* Allow the pot to get noticeably lighter before watering again. Continue this process of watering thoroughly but not too often until you see roots through the drainage holes. The plant is now ready to be potted on.
