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.
Extremely healthy plug plants well packaged
The plants were absolutely tiny, the smallest I’ve ever seen. The website photos very misleading.
We are sorry that you have been disappointed, we do try to make the size as clear as we can in the size guide tab within the information box so we do apologise that this may of been missed.
Delighted with quality of this plant and all the others I ordered - about 30 in total. They were, without exception, in excellent condition and are now happily settled in the garden or in hanging baskets filling out nicely. They were delivered exactly as scheduled, in spite of lockdown restrictions, which also impressed me. Thank you.I would have no hesitation in ordering from Brookside Nurseries again.
Well grown plants
Excellent condition on arrival
First time to order bedding plants with Brookside Nursery and I’m very pleased. They were all well packaged and in good condition. Would definitely order again.
All plants arrived in great order which gives you extra points considering delivery conditions at present. Cosmos doing well.
Looked a little long, but they do grow long and tall so we shall see.
One of the best tall showy flowers for the border - and the bees love 'em.
