We’re so pleased to see so many photos on social media of the plug plants that you’re receiving in the post. Some customers – perhaps those of you who are turning to your gardens during this time of social distancing and self isolation – are asking us about what to do with their plug plants when they arrive. We’re aware that many of you may be new to gardening and might need some help and advice, so here’s a quick guide to what to do when your plants are delivered.
- Unpack your plants as soon as they arrive – even if you haven’t got time to plant them up straight away – they’ll need some air after being enclosed in their packaging.
- Give them a drink! The plants may well be thirsty after their journey, so moisten the plugs of soil at the roots of the plants if they are dry.
- Don’t worry if the plants look a little sad on arrival; they should perk up once you give them a drink.
- When you’re ready, gently tweak each plug plant out of its packaging and plant each one into a 7-9cm pot, filled with a good quality, multi purpose compost. This is what is known as ‘potting on’.
- Gently press the plug plant into the compost, adding more to top up the pot if necessary. Don’t fill the pot to the very top with the compost – you need to allow for watering.
- Place your pots somewhere where they will stay fairly warm and get lots of light – a windowsill, or a table near a window is fine if you don’t have a greenhouse or conservatory.
- Keep the compost moist, but try not to overwater.
- Your plants will start to grow; getting bigger and stronger by the day.
Once your plants have developed more leaves and are looking more robust – usually in late April to mid May (depending on the weather/climate in your area) – you can toughen them up ready for planting out in the garden by popping them outdoors during the daytime and bringing them in at night. You should do this for 7 – 10 days prior to planting out. This is known as ‘hardening off’. It’s important to protect your growing plants from any possible spring frosts, so do keep an eye on the weather forecast!
After you’ve ‘hardened off’ your plants, they’re ready to be planted out into the garden where you can watch them continue to grow and flourish – just remember to water them!
NOTE: If your plants are destined for baskets or containers which can be easily moved indoors and out again, then you can plant your plants into their final containers a little earlier if they have made good growth. You can then harden them off as explained.

Sonia has a ‘hands off’ approach to gardening and believes that this helps to encourage bees, butterflies and other wildlife. (That’s her excuse anyway!)
Your instructions don’t say anything about plugs delivered in late summer
Plugs delvered in late summer should be potted up and grown on. If the are winter bedding then you can plant outside in their final positions once they are big enough. For frost tender varieties, these will need to be grown on in warm, frost free conditions over the winter months for planting out in the following spring.
Hi I brought 72 perennials postiplugs although some have died I would like to know how big they have to be before transferring them to the ground they are in a mini greenhouse at the moment
Kind regards
Hello Julie. You need to pot up your plugs into small pots about 8 or 9cm. Keep them in a frost free place (your mini-greenhouse should be fine) and then in spring, when they have filled the 9cm pots with roots, they will be ready to plant out in the open.
I received my package and it is a mix of good and poor plants depends on the kind. As the poor ones were what I would really like to have, I wonder if they could send a replacement for only those that did not survive the delivery. Could you please forward my contact to your team so that I could show them the pictures and tell which ones were dead?
Hello – I have passed your details to our customer care department who should be in touch with you shortly.
I’m still waiting for your staff getting in touch with me 🙁 Could you please check with the team?
Hello Tomomi. I’ve contacted our customer care team again and they should be in touch with you shortly.
Just received the plugs. Most of them were in a reasonable condition. Thank you. Two slots were missing (one with soil but no plant, another without soil/plant). I guess that’s within the expectation?
Hello – I have passed your details to our customer care department who should be in touch with you shortly.
You should get everything you pay for Thompson and Morgan have a very good customer service and they’ll send you replacements for items missing
Today my garden-ready primroses arrived, presumably to flower in spring. I will do some re-organizing of my borders probably in November (to plant new roses). What should I do with the plants until then? Should I pot them on and keep them indoors until later (when?) or plant them in the soil now and move them later?
Hello. You would be best to pot them up and grow them on in a sheltered spot outdoors until you are ready to plant them out. They won’t mind being outside as the weather is still warm, and they be nicely hardened off for when you plant them in November.
Does this apply also to delphiniums and foxgloves (arrived two days ago in good condition, thank you, and potted on this morning)? They’re now in an open frame.
That sounds ideal. As winter approaches, you should move these young plants to a more protected position in the greenhouse. a porch or at the very least, cover your frame. Whist these plants are perfectly hardy when they are well grown and fully established, you will find that they are more vulnerable when young, so its best to err on the safe side!
They’ve been in a frame since we spoke. The foxgloves are all fine but the delphiniums are really struggling — in fact most seem dead. Any way I can send pictures?
Hello Jeremy. I’ve passed your details on to customer care and they should be in touch with you soon.
Do you ever supply healthy plants? Judging by the comments above I doubt it. If I had known all this information prior to ordering ,I wouldn’t have bothered.
In my case I ordered New Guinea Impatiens the first order all arrived but mostly dead, a replacement was sent , all looked healthy, but the roots were the same colour as the compost, I have 8 left alive ( just) but making no new growth or roots.
Also ordered Begonia Apricot shades these went the same way and I was refunded for that order. But was told it was very unusual for you to receive complaints.
Also ordered some Foxgloves back in March on a Special Offer from Gardeners World. Waited till May for that order, these were dead too.
I have a greenhouse , but can’t raise the dead .
Won’t shop with you again!

Agreed! Lost over 80% of tiny plug plants despite being very experienced and usually very successful at growing plants on. Dreadful weak plants.
Hello – I have passed your details to our customer care department who should be in touch with you shortly.
I had ordered the apricot begonias last year, myself and my friend, they grew and where absolutely stunning, so many ppl commented when passing my house, I’m defo not a gardener, but actually shocked myself with the begonias, maybe you just had a bad lot, also depends whose delivering!
I purchased some plugs last week. They arrived yesterday and I am very disappointed as the half had no tops, most of the leaves are missing and the ones still on the plants looked awful. I purchased a similar item from a different nursery on the same day, the plugs arrived earlier and they had no damage or missing leaves.

Thank you.
Had an email yesterday from T&M they apologized for the damage in transit and have send out some new plants to replace the original.
Delighted with the quick response and would like to thank Jake for his email.
Thank you T&M fo the outstanding customer service.
Thats good to hear. Will pass on your comments to our customer care team. 🙂
I bought some plug plants (nicotiana) from T&M through Amazon. They arrived battered and rotten. Whilst the busy lizzy plugs I bought from other company are carefully packed and not a single leaf is broken! I will never buy plug plants from T&M again.

We ordered plug plants sometime in March and didn’t receive until June. No sign of flowers yet and quite a few were dead when we received them! This is now July and not sure when we will see any sign of flowers? We are very disappointed of the time they were sent!

All the plants I have bought from T&M and QVC have come with damaged leaves and rotten also, plus the way they have arrived from their courier is pathetic, they always come with battered boxes or left upside, despite there being on the box “This way up” I have complained to T&M about this but nothing seems to be done. The last order I got, the two Weigela Towers of Flowers I have just received had both pots squashed into an oval shape in the green plastic container. Surely the staff should have put them in a more suitable container. I did warn T&M that this order needs to come in better condition…..One of the plants had brown leaves on it. They may be a big company, but big isn’t always better….

Just received my pack of much waited for Annual Sub Collection and i am very dissapointed with quality of the plug plants. Most of the begonias are broken and just a stem left all the leaves are broken off. One row of plants are missing altogether can’t tell what they are due to all leaves broke and in bottom of packaging.Some of the plants have yellow and mouldy leaves.Both my husband and i stood and laughed at the package of plants looking as if someone had sat on the box. Come on Thompson & Morgan send out quality to your paying customers!

Thanks Sue for replying to my comment reading alot of comments from customers numerous have all had the same problem .Paying a well known company hard earned money for plants i didn’t expect dead plants delivered .I will wait for the customer services team to ring but reading other comments of ex customers with problems waiting for the call i don’t hold out much hope of being contacted .
Just recieved my second order of 72 begonias.Well Thompson and Morgan you should be ashamed of yourself sending a package of just soil and storks no leaves .All leaves were broken off and everything was just a mess in the cardboard package .You should be ashamed taki g peoples money for plugs that have to go in the bin . They must have been posted out like that lets go to our local garden centre you gardeners don’t waste your money with this company. Please don’t tell me you will pass on my details never heard last time i complained .Photos taken of order if you even want to look or are bothered .

I would like to say how pleased I am with my plug plants this year. I ordered 144 of various types of plug plants (postiplugs) and 142 of them are thriving. I will be certainly ordering again.
Thats great news! Thanks for the positive feedback 🙂
I have purchased lots of super plug plants and I was wondering if they are able to be planted into pots and beds after a 3 days of being outside during the day?
Thanks
Hello
It depends on the size of the plug really. Plug plant, mini plugs, and Jumbo plugs are all best potted up and grown on indoors or in the greenhouse until they are a bit bigger. You can then harden them to outdoor conditions before planting out. We usually recomend 7-10 days but the warmer the weather is, then the less of a shock it will be for them.
Garden ready plants are much larger so these can be hardened off on arrival and then planted outside. You may well get away with just 3 days but it is all dependant upon the size of the plant and the weather. I would certainly recommend throwing some horticultural fleece over them on cool nights while there is still a risk of a late frost.
Hope that helps
I have received my plug plants they look healthy. I have put in pots to get them ready for the garden. Hopefully they will grow. I had yo Google what to do with them first,
Hi I have just received my order of 72 plug plants, I didn’t realise they were so small!
I have checked the box and they look nice and healthy, unfortunately the Maxicrop Plant Treatment was not included, is this coming separately?
There are no instructions with the plants and as I am a novice gardener I cannot tell which plant is which, so do not know where to plant and how big they will grow.
I have looked on the website and found out how to transfer them into separate pots and keep indoors until the frost has gone.
I am going away next week for one week so will not be able to water them, have you any suggestions please on what to do?
Further to my post yesterday I bought compost and pots for my plants.
When I started removing the plants I noticed several were pot bound but managed to untangle them.
One row of six looked dead, I do not know what type of plant they should be, could you send me a replacement/refund?
Once potted up they look mostly healthy.
After removing the plants I realised the instructions were underneath and the tray marked alphabetically, too late now but I will know next time.
When could I expect a reply from my earlier blog re watering whilst away?
It says the the comment is awaiting moderation?
Many thanks

Received plug plants second week of May. How long approximately if I now plant them up until they are ready for hardening off prior to planting in garden or hanging basket
It really depends on how quickly they grow, and what the weather is like. However I would expect them to be making some decent growth by the middle of June and you should be able to plant them out by end June.
Quite a number of my recently received Bizzie Lizzie plug plants have not survived the journey. Is there a policy for replacement?

Just recieved garden ready Begonias how long can i leave in trays before i plant out wary of current weather ie frosts.
You can plant them directly into hanging baskets and containers if you have a greenhouse or conservatory where you can grow them on for a few more weeks. If not, then I would recommend potting them up into small containers and growing them on your windowsill until the middle of June, when all risk of frost has passed. You can then transplant them into ther final positions outside.
Hope that helps
Hi, my Fuschia and Petunia plugs arrived safely and have been potted on. Unfortunately I mixed them up while planting them so don’t know which variety of each is what now. Is there any way of telling? If not it will be a nice surprise.
Thank you
Petunias have a lighter green and more rounded leaf tip. Fuschias are more pointed at the tips and tend to be darker in colour. Once they have made some growth it will become much more obvious!
I have just received replacement dwarf French bean plants. The first lot arrived dead. The replacement arrived today very badly packaged and 3 out of 6 are snapped in half, my petunia postiplugs which arrived a few days earlier are all dead. I am really disappointed and don’t think I will order from you again.

I have ordered plug plants over several years from t&m and have always had success in growing them on my advice to inexperienced gardeners is not to buy small plugs but buy garden ready plants a dearer option but cheaper in the long run small plugs may arrive looking stressed/tired but if handled correctly will grow into strong plants
Leslie Godman 26/3/21
Thanks, your comment is helpful,I do wonder when the plugs are being advertized as to whether they can go straight into baskets,think I will wait for garden ready
I wish I had read these reviews before enthusiastically ordering lots of plugs from you. My nicotiana plugs were soggy and all the leaves had broken off. The same with my gazania plugs, although I had three that were useable and some of the begonias were soggy and stick together.
If all the leaves are broken and there is no stem showing will they regrow or are they dead? I usually grow from seed, wish I had and saved my money

I’ve had my lavender&foxglove plugs for about four weeks and doubled to 6 inches high on window sill.
If I am supposed to put in garden in spring there going to be pretty big?
Is this correct?
Hello
Yes that is correct. Your plug plants should be overwintered in cool conditions for planting out in spring. If you have a greenhouse or an unheated conservatory then you could grow them in there for the winter months. They will probably find it too warm in your main home unless that are in a particularly cold room. You will notice that growth will slow down considerably once we get some colder weather. It has been a very mild autumn this year!
Do you sell the small plastic plugs that come with my order please.
Hello – Are you referring to the little cells trays? Unfortunately we don’t sell these.

When can I plant out my garden ready plug runner beans
Hi Linda
Runner Beans are not hardy so you will need to wait until all risk of frost is passed. That’s usually toeards the end of May. In the meantime, pot them up and grow them on in frost free conditions.

We ordered plants for our hanging baskets and tomato plants. They were all sent out separately and arrived in a terrible state. We could not save any of them and were only offered half of our money back. We will definitely not be buying anything from Thompson-Morgan in future.

I have also bought plug plants from T&M and they have come in such a poor state, with leaves damaged and yellow and snapped stems. They are not the only ones by the way, other companies are just as bad. I don’t buy plugs or anything online anymore. Too much of a risk and why should we lose money, especially nowadays.

So, ordered Geranium and Petunia plug plants on order number SO002322219 on 15th April. One lot arrived dead, managed to save about 8 from 72 (not a great average). Other lot still not turned up. Although was offered replacement for July delivery, not bad when I ordered on 15th April for delivery within 21 days.
Please, please get someone to process my refund !!! Even a reply telling me its being done would be nice.

Dear Sue,
My partner ordered plants off you, we are still waiting for them to arrive and the one lot that did arrive were all dead and broken. We couldn’t save any from the 48. I think that you need to get a different carrier.

I HAVE had plants over th he last four months apart from one batch they are fine even replaced the few that had died in transit always happy with post & my plants have really thrived & are looking good ThankYou
Hi Barbara. That’s fantastic news. So glad to hear that your plants are thriving 🙂
Last year I ordered & spent nearly £500 worth of plants from you. My petunias were awesome. Some arrived alright & with my care blossomed however others arrived with a mixture of some plugs damage on delivery. Some like my magnolia never took off, sooo disappointed. You did ask if I wanted a replacement but I did not respond. You did send me replacements when some orders failed to arrive I thank you for that. Some orders never arrived & were cancelled while I had orders that was suddenly out of stock & could only be delivered at the wrong time of the year to plant so I requested a refund. After a confirmation of refund last year, this year suddenly I received 2plants I cancelled due to very very late arrival. I have yet to check if they did refund me for these items I had cancelled. I can honestly say when I have emailed customer care they have replied and sorted out my issues, refunds or replacement but do take a long time to do so. I noticed somehow customer care & order service do not seem to communicate well with each other. This year I have orders sitting in my inbox however hesitant to go through with it sort of needing reassurance all will be well? You need to be consistent for me to feel confident to pursue my orders.

I am one of the vulnerable people in this virus problem and unable to leave the house at all so not able to visit garden centres for my annuals. Unfortunately I have a complaint about the plants I have bought from you recently. I bought the 35 annual plants for 6.99 but I was disappointed that most of them are so small that they will never be big enough to plant out in my tubs. As they are annuals they were a waste of money what with postage on top of the purchase price. I did have three really good tomato plants which are looking good. Why do you sell such tiny plants at this time of the year as they need to be bigger so that they can be planted in the tubs.

I was looking forward to getting my flowers, the first batch sent arrived after the second and were all dead as it took 9 days to arrive, they had actually rotted in the box and were just stalks. the rest arrived in not perfect state and I could not save them all. Spent a fair bit and have nothing to show and no response from customer care.
