Please Note

These seeds should ideally be sown this season. All our packets have ‘Sow by Date’ guidance on them, this is the date the seeds should be sown in order to achieve the highest rate of germination. You will still see the same high-quality plants if sowing in seasons after the ‘Sow by Date’ but may see a reduction in germination rate

How you will receive your plants:

Selected by our team of experts and sent from our nursery, you will receive your garden ready plug plants in plug trays in a box. These are designed to keep your plants secure and to prevent damage in transit.

Can’t plant straight away?

If you aren't able to plant your plugs up straight away then ensure they stay moist. You can place your plugs on a saucer or tray of shallow water so they are able to stay hydrated. Aim to have your plugs planted within 3 days.

Planting tips and hints:

Planting in containers: Sprinkle a layer of stone or gravel in the bottom of the container to aid drainage. Use a high-quality young plant or general-purpose compost space the plugs evenly with enough space to allow the plants to grow. Mix in a slow-release granular fertiliser in the compost before planting to provide plenty of nutrients. Water thoroughly once planted up. Continue to water every 3-5 days and don't allow the container to dry out.

Planting in the ground:  Dig a hole approximately twice as deep and 3 times as wide as the plant, if your soil is heavy mix in general-purpose compost, horticultural sand and stone or potting grit to ensure good drainage. Gently compact the soil around the plant and water thoroughly.

Feeding and aftercare: Deadhead regularly to prolong the flowering period. When feeding use a liquid feed high in potash.
