Geranium Horizon Scarlet | Tray of 20 Plug Plants

The Horizon range of Geraniums are one of the best for all-round performance and colour.

Geranium Horizon Scarlet is one of the most popular colours with its dense flower heads appearing above the well zoned markings on the leaves.

The sturdy and compact basal growth of the Horizon range makes it perfect to use in bedding schemes as it gives good ground cover and the flower heads grow uniformly to give a finished look.

Size guide - Tray of 20 Plug Plants 

Securely rooted, strong plants in mini-plugs of compost. Will need to be transplanted and grown for a short while before planting out ready to flower. Tender varieties will need protecting from frost. Compost volume around 3cm deep x 2cm square. Foliage height 1.5cm-5cm (depending on variety). Full growing instructions are provided.

Using a good quality multi-purpose compost, pot up your plugs into 10cm pots or use the 6 Pack Cell Plant Trays. Once your Geranium plug plants have been potted on and labelled, water them in well and grow on for 5-6 weeks.

If preferred you can pot on the plugs into hanging baskets, flower bags or pots. Add a slow release plant food like Miracle-Gro Slow Release All Purpose Plant Food to your compost which will give extra nutrients for strong and healthy plant growth.

Keep plants frost free until mid/late May and then harden off before being placed in their final positions when the risk of frost has passed in your area.

Brookside Nursery Top Tip – Pinching out the first flower buds will ensure that the plant will put its energies into a good root system and foliage growth which will result in a stronger, bushier plant with more flowers.

*** For packs of 40/20 plug plants gently remove the small plugs from the tray by pushing up from the bottom using a pencil.
