When your Geraniums first arrive, place the tray in a frost free, light, draught free area (if you do not have any indoor space, cover the tray with horticultural fleece and leave in a sheltered spot in the garden) and water gently either by misting or by standing in a shallow tray of water.
Allow the plants to rest for 24 hours. Don’t worry if the leaves appear slightly yellow or if a small amount of compost has come away from the root blocks.
Medium sized geraniums should be grown on for 2 - 4 weeks before planting out, large sized geraniums can be planted straight out as long as risk of frost has passed.
- Ensure plants have been well watered.
- Use your finger or a pencil to push the individual cells up from below and out of the tray. Pull gently up by gripping one of the leaves. Do not try and grab the stem as this will significantly damage the plant.
- Fill 9cm pots with compost and create a small hole in each to plant the cell in (one plant per pot). Ensure the point at which the leaves and stem are joined is above the top of the soil, firm the plant in gently.
- Water gently immediately after transplanting and place in a warm light position out of direct sunlight.
- Feed using a liquid feed after one week and keep well watered.
- After 2 – 4 weeks they should be ready for planting out into beds, borders hanging baskets or planters keeping the full stem exposed and the plug submerged so the top of the plug is level with the soil surface. Once planted water in generously.
- If there is still a slight risk of frost once planted out, protect with fleece overnight to prevent discolouration of the leaves.
