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 20/40 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.
the plants were a little damaged but managed to save most of them
Packaging was brilliant, they've been repotted, looking strong, healthy and sturdy. Looking forward to seeing them bloom in the garden as and when
Lovely plug plants, doing well very well a week on.
I was very pleased with them. I also potted them straight away and I’ve even got a flower now!! They are good strong plants. I haven’t grown Cosmos before but so far so good. The rest of my order was great - good strong plants, all doing well. The greenhouse looks alive again. Thank you for all your efforts at such a difficult time. Keep safe.
Arrived safely -well packaged - excellent condition. Repotted into large modules in my frost free greenhouse and they are doing really well. Well done Brookside.
I am a little surprised that these Cosmos are already in bud. I will I think have to remove these buds so that energy will be directed towards the plants reaching their proper size. Why has this happened? Secondly if I had been in time I would have cancelled this entire order as it was for a display and sales through our (Cheltenham Horticultural Society) spring show, which of course has been cancelled due to Covid-19 isolation. I only was reminded of this order when you sent despatch details which you said made it too late to cancel. I have to accept this was my oversight. Part of the order however was not included but to be sent later so I cancelled this single item. I now find I have only been refunded £2.04 as the total order fell below free P&P rather than the £6.99 this item cost. I thought this was mean and totally unnecessary as I have saved you having to deliver a second time. Our society has lost money for all outlays for our shows which we cannot get refunded by any means. In these terrible times this additional loss although small has made me feel sad and disappointed in the unsympathetic attitude of your company. I would like to hear if this is something you feel could be remedied in light of my complaint.
