Garden Ready Plants - If you’ve fallen behind with your planting or if greenhouse space is limited, we can help you catch up with our garden-ready plug plants. These sturdy plants are larger than other plugs so they can be planted straight out in the garden provided that there are no forecasts of frost. Perfect for filling containers, baskets and borders without the need for growing on.

Pot up lobelia plugs into 9cm pots and grow on for transplanting into final containers or baskets later on. Alternatively, plant plugs directly into flower pouches. Grow on in warm frost free conditions until plants are large enough to be transplanted into their final containers and bedding displays. Caution: irritant to skin and eyes. Garden Ready plug plants can be planted straight out in the garden provided that there are no forecasts of frost.
