The most economical way to purchase your plants. Securely rooted, strong plants in mini-plugs of compost. Will need to be transplanted and grown on before planting out ready to flower. Tender varieties will need protecting from frost. Compost volume around 2.6cm deep x 1.8cm square. Foliage height 1.5cm-5cm (depending on variety). Full growing instructions are provided.
General Growing Advice
Using a good quality multi-purpose compost, pot up your plugs into 10cm pots. Once your plug plants have been potted on and labelled, water them in well and grow on for around 5-6 weeks. Water once the compost starts to dry out.
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.
Water as necessary giving a liquid feed such as Neudorff Organic Plant Feed as instructed throughout the growing season.
***For packs of 40/20 plug plants gently remove the small plugs from the tray by pushing up from the bottom using a pencil.
Cosmos Specific Advice
Regular deadheading of cosmos will encourage and prolong more blooms. If deadheads remain then the cosmos will self-seed. Do not over fertilise as this will promote more foliage growth rather than more flowers. Pinching out the tips at around 15-20cm will encourage bushier plants.
Good sized plugs in healthy condition
I found that the seedling arrived in good order and condition, all very healthy and since planting them a few weeks ago, none of them have died and all are going great and look very healthy
All plugs in good condition for tender plants
Following on from last years order of the same, which made a spectacular summer show, I reordered this year. The plants arrived well packaged and in good condition and are very healthy plugs already doing well in the garden so all being well I will have a repeat show of last year.
Plug plants growing well, looking forward to seeing them flower.
excellent plants and well packed , so arrived in good condition
Plants arrived in very good condition , they have been potted on and are growing well, looking forward to the arrival of my other orders.
Really poor quality. Packaging seemed too small. The tops of the plants were bent over and really wet and black. Only managed to save 12 plants and not sure if these will all survive.
