Plug plants delivered later in spring, when the weather is warmer and the plants slightly larger, can be planted directly into their final container, rather than being grown in small pots first.
Plug plants, pot, compost, watering can
Larger plug plants can cope with being planted in their final container, ready to provide colour during the summer.
Use fresh, sterile compost (with added water-retaining gel and controlled-release fertiliser if you wish) and arrange the plants so that they all have enough room to grow.
Choose a mixture of upright and trailing plants, with a tall plant in the centre to give height to the display.
Water well to settle the compost around the plants. Keep them under protection while they establish and until all risk of late frost has passed.
