"How much does Thompson \u0026 Morgan delivery cost?"

Mixed orders containing both seeds and other items carry a flat fee of £6.90, regardless of the number of items. Bulky goods such as large pots or furniture cost more; the exact surcharge appears in your basket before you check out."

"Does a Thompson \u0026 Morgan discount code work on delivery?"

"No, standard percentage-off codes apply to the product subtotal only and won’t reduce delivery fees. Thompson \u0026 Morgan occasionally runs free delivery promotions, so keep an eye on the offers listed at the top of this page. If you’re looking to save on postage, a code specifically for free delivery will be clearly labelled, but we don’t always have one available."

"How do I request a Thompson \u0026 Morgan catalogue?"

"You can request a printed catalogue by filling in the form on the Thompson \u0026 Morgan website. If you supply your email address, you’ll also receive news of special offers and gardening tips.

Once you have the catalogue, use the Quick Shop function online: enter the catalogue numbers straight into the quick order form to add items to your basket without browsing."

"Can I connect with Thompson \u0026 Morgan on social media?"

"Yes, the brand has active accounts on Facebook, Twitter, Instagram, YouTube, and Pinterest.

The social feeds often highlight new plant releases, limited-time offers, and seasonal gardening inspiration."

"Is there a refer a friend scheme?"

"Yes. When you refer a friend who hasn’t shopped with Thompson \u0026 Morgan before, you both receive 20% off plants, bulbs, and seeds.

The voucher typically arrives by email shortly after your friend’s order is confirmed."

"How do I know what to order?"

"If you’re new to gardening, the Thompson \u0026 Morgan website has a comprehensive set of gardening guides covering everything from sowing seeds to identifying pests and diseases.

Start with small, easy-to-grow plants and build from there."

"Why isn’t my Thompson \u0026 Morgan discount code working?"

"There are several common reasons:\n1. Your basket doesn’t meet the minimum spend. For example, TM_TAW327W requires £100, TM_TAW326W needs £60, and the VC1 code requires £55.\n2. The code is limited to a specific product category, such as Garden Ready Plants (TM_TAW404W) or Potted Hardy Plants (TM_TAW413W). Check that your items match the code’s terms.\n3. You’ve already used another code. Only one promotional code can be applied per order.\n4. The code may have expired. Offers have limited validity, so it’s best to use them soon after finding them.\n5. You’re trying to enter a refer-a-friend credit as a promo code. Referral rewards are account vouchers, not discount codes.\n"

About the Brand

Thompson & Morgan started life in 1855 when William Thompson began selling seeds from his home in Ipswich. Nearly 170 years later, it’s one of the UK’s largest mail-order seed and plant companies, dispatching millions of packets of seeds, young plants, and bulbs to gardeners across the country every year. The brand now sits within the Branded Garden Products group, alongside other well-known horticultural names, though its own breeding programme continues to introduce new varieties that you won’t find elsewhere.

The range spans almost everything a gardener could want: from classic bedding plants, perennials, and shrubs to vegetable seeds, soft fruit bushes, and seed potatoes. There’s also a growing selection of outdoor furniture, from bistro sets to modular rattan lounging sets, and a well-priced houseplant collection, with many options under £20. You can order online or request a printed catalogue and use the Quick Shop feature to enter catalogue numbers directly at the checkout.

Several extras make the experience notably smoother. The Thompson & Morgan app offers plant care reminders, identification help, and seasonal growing advice. The refer-a-friend programme gives both you and a friend 20% off plants, bulbs, and seeds once they place their first order. A free email newsletter delivers gardening tips and alerts about new offers, and the website’s gardening guides cover everything from sowing seeds to diagnosing pests and diseases.

We’ve been tracking Thompson & Morgan discount codes since 2008, and our users typically save around £7 on an average spend of £44. Bookmark this page to combine the features above with the latest verified codes and keep your garden spending under control.

How to use

Pick a code from the list above and click the offer card. The code copies to your clipboard automatically. For example, TM_TAW327W takes £20 off orders over £100.
Head to www.thompson-morgan.com or tap the store logo at the top of this page. Browse seeds, plants, or gardening kit — most codes work across the full range, but some are restricted to categories like Garden Ready Plants or Summer Annuals.
Add your chosen items to the basket. If a code requires a minimum spend (e.g. £60, £100), double-check your basket total meets that threshold before proceeding.
At the checkout, find the promo code box, paste in the code, and click apply. The discount should reflect in your order total immediately.
Review the updated total to confirm the saving, then complete your purchase.

Referral Rewards Thompson & Morgan’s refer-a-friend deal isn’t a code you enter at checkout — it’s a separate link you share.

Once they complete that order, you’ll receive a 20% discount on your next qualifying purchase too. The referral reward is applied as a voucher tied to your account, so watch your inbox after your friend checks out.

Shopping Guide

When’s the best time of year to order from Thompson & Morgan? Spring and early summer offer the widest selection of bedding plants, perennials, and vegetable starts, but prices often drop as the season winds down. We’ve noticed that clearance events pop up from late August through September, cutting the cost of summer-flowering bulbs and fading perennials. If you’re after fruit bushes or bare-root trees, order in autumn or early winter when the range is freshest. The January sales sometimes throw up garden furniture bargains too. For the strongest code stack, aim for the shoulder periods when promotional codes and reduced prices align.

Should I buy seeds or garden-ready plants?

	Seeds	Garden-Ready Plants
Cost	Few pounds per packet	Typically £5–£15 per tray
Effort	Sow, prick out, harden off	Plant straight out
Speed	8–12 weeks to maturity	Instant impact
Risk	Higher failure rate for beginners	Lower, but needs watering in

If you’re patient and gardening on a budget, seeds win hands down — especially with a 10% off seed orders code like TM_TBEH4. When you need quick colour for a garden party or you’re filling gaps left by slugs, a garden-ready plant pack with a 10% code (TM_TAW404W) gets the job done without the wait.

How do I get the biggest possible discount on a large order? The £20 off £100 code (TM_TAW327W) is often the standout for big spends, netting you effectively 20% off. If your basket sits around £60–£99, the 15% off £60 code (TM_TAW326W) edges ahead. Refer-a-friend gives a flat 20% off your next order once a friend buys, so it’s worth lining up a referral before a big shop. Note that you can only use one discount code per transaction, so pick the highest-value one. Our data shows users typically spend £44 and save £7, so pushing your basket above £100 unlocks noticeably better returns.

What catches people out when using Thompson & Morgan discount codes? The biggest tripwire is the minimum spend threshold. Codes like the £20 off £100 require you to hit that exact total before delivery; adding a £4.95 delivery charge doesn’t count. Another common snag: some codes are locked to specific product lines — the 10% off Garden Ready Plants won’t work on seeds or furniture. We’ve also seen confusion with the refer-a-friend discount, which arrives as an account credit, not a code you paste at checkout. Always check the basket total and code terms before applying.
