  • Harvest both tomatoes AND potatoes from this unique plant!
  • Incredible innovation in vegetable growing
  • All natural - no GM


Here's another major horticultural breakthrough from Thompson & Morgan! Specially hand-grafted plants producing potatoes AND tomatoes are now available to UK home gardeners for the first time. Above the ground harvest harvest over 500 cherry tomatoes with a Brix level of 10.2 - that's sweeter than supermarket tomatoes. Fruits also have just the right level of acidity that only the tastiest tomatoes have.

BUT THAT'S NOT ALL... Below the ground harvest heavy yields of up to 2kg of delicious white potatoes which are incredibly versatile. You can boil them, mash them, roast them or make chips. That's right! From one plant you can harvest tomatoes AND potatoes. This concept has been worked on for over 15 years, but this is the first time that plants have been successfully produced commercially. Tomatoes are members of the potato family and are therefore naturally compatible with potatoes. Each TomTato® plant is specially grafted by hand to create this unique double cropping feature. There's no genetic modification - it's an all-natural, and safe process.

TomTato® Improved

We've reworked this exclusive grafting concept for the 2016 season for even better results in your garden. Following feedback from our customers we've retained the heavy cropping, super sweet tomato variety, promising you more than 500 cherry tomatoes per plant, but we now graft it to a different potato to bring you 50% more fresh, tasty spuds at the end of the season. Once the tomatoes have finished cropping, cut the plant at ground level and harvest up to 3kg of potatoes two weeks later. Our TomTato® performs perfectly in the ground but can be grown in a large 40 litre pot making it ideal for small gardens, patios and balconies too - grow potatoes and tomatoes where you've never grown them before!

Plants come with growing and aftercare instructions. (Not that you'll really need them - these plants are so easy to grow!) Grow them indoors or outdoors, in a patio pot, on your allotment or on the vegetable patch.

TomTato® makes the perfect growing partner for our new Egg & Chips™ plant. Why not try them together for three easy crops from two large pots?

Companion planting: Try growing tomatoes with French marigolds to deter whitefly, and basil, chives or mint to deter aphids and other pests.

How to Grow

• Grow TomTato® plants on in warm, frost-free conditions until all risk of frost has passed, potting on if necessary to a slightly bigger pot. Alternatively plant TomTato® directly into its final position in a frost-free greenhouse. Once all risk of frost has passed, gradually acclimatise indoor plants to outdoor conditions over a period of 7 to 10 days.

• Grow TomTato® in a greenhouse or sheltered position outside in full sun. For best results grow in a container which holds at least 40 litres of compost such as our Patio Planters, or a deep container with at least 50cm (20") diameter. A large container is needed for proper development of both crops.

• Plant grafted tomato-potato plants with the graft union below soil level, burying the stem up to the second tomato leaf from the base. This aids stability and growth, and ensures the potatoes develop fully underground. Water thoroughly after planting.

• Support your TomTato® plant as it grows, using several stout 1.5m (5') canes, or a similar strong support frame. TomTato® produces vigorous growth and heavy trusses of fruit, so will require regular tying to its support with soft garden twine.

• Alternatively grow TomTato® plants in the ground on fertile, reliably moist, well drained soil. Prepare the soil in early spring by adding plenty of well rotted manure to improve its structure and fertility. Space plants at a distance of 60cm (24") apart and water them thoroughly after planting.

More Info

• Water TomTato® plants frequently to keep the compost evenly moist. Once the first truss of fruit has formed, feed regularly with a high potash plant food such as Chempak® Soluble Tomato Food (1kg pack just £9.99). Feed weekly at the first truss stage, twice weekly at the second truss stage and at every watering by the 3rd truss stage. Plants will benefit from the application of Chempak® Calcium Multi Action Fertiliser during peak cropping times to prevent blossom end rot.

• Due to its fast growth, make sure you tie TomTato® to its support regularly. Each week remove any side-shoots that develop between the main stem and the leaf stems. Watch our Sideshooting Tomato Plants Video for further advice.

• TomTato® plants can sometimes produce potato foliage from the base of the plants which may grow through the tomato foliage. These can be removed by pinching out to ground level and will not affect the potato harvest. If however this is left to grow through the tomato foliage, any potato flowers should be removed. Top up the compost in containers every so often to prevent potatoes near the soil surface from becoming green and inedible.

• Once container-grown plants have produced 6 or 7 trusses pinch out the top of the main stem, two leaves above the last truss. This focuses the plant’s energy on producing a good crop of high quality tomatoes. Greenhouse plants do not require stopping and can be left to grow on as required.

• Tomatoes can be harvested as they ripen from July to October. To help ripen green tomatoes, harvest red tomatoes regularly. If growing TomTato® in containers they can be moved to a frost-free position in the autumn for prolonged crops of tomatoes. Once the tomatoes have finished cropping, cut back plants and harvest the potatoes below. If plants contract the fungal disease blight, cut the stems to ground level and dispose of all foliage. Leave potatoes in the ground for 2 weeks before lifting.

• If growing TomTato® outdoors, remove any remaining green tomato trusses before the first frosts in autumn. Cut the plant stem to ground level and leave for 10 days before lifting the potatoes below. PLEASE NOTE: Although potato plants normally produce poisonous fruits, crops from TomTato® pose no risk and have been certified free of any harmful glycoalkaloids.

Thompson & Morgan strives to ensure that all its plants are delivered to you in the perfect condition for planting. While the majority of our nursery plants cope well with slight delays in intransit, sadly, the time it takes to deliver to certain locations in the UK means that we can't guarantee this for some of our smaller plug products and tender bedding and vegetable lines, which do not respond well to the extra journey time. So regretfully while we offer the majority of our live plant offering nationwide, we are unable to ship plugs, begging plants and tender vegetable plants to the following areas: HS, IV41-IV49, IV51, IV55-56, KW15-KW17, PA34, PA41-48, PA60-PA78, PA80, PH40-PH44, TR21-TR24, ZE1-ZE3
