Size guide - Pack of 5 Large Plug Plants 

Pot Ready, Large, Healthy plants individually rooted in large plugs of compost. Ideal for planting into baskets, containers or small areas in the garden. Best results achieved if grown on for a short while in 9cm/10cm pots prior to planting out if planting straight into garden borders. Tender varieties will need protecting from frost. Compost volume around 4-5cm deep x 3-4cm square. Foliage height 5cm-12cm (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.

Disappointing

The problem was that the plugs had moved in transit. I’m hoping that I’ll get a couple at least from the pack of five. To be fair, I can see that they would have been nice plants had they all arrived safely.

Although raising many plants from seed for my small garden, there are some I find difficult for window-sill propagation and early stages. I decided on Brookside via an online search and finding your white cosmos which is, for me, an annual priority. My plants arrived as arranged, beautifully packaged and in excellent condition. Now potted up, they are thriving and growing on well, awaiting warmer weather and transfer to the garden. Your catalogue makes for irresistible reading. I will undoubtedly be back for more next spring and have recommended Brookside to many friends.
