PotaTom: tomatoes in view, potatoes underground

Your care table

A tomato stem with a second story underground

Green tomato foliage catches the eye first: divided leaves, an upright stem and room for flowers and later fruit. The other part lies underground. PotaTom is the named tomato-potato plant by Pick-&-Joy. The grower describes it as a graft, joining the tomato top to a potato rootstock. Tomatoes are Solanum lycopersicum and potatoes Solanum tuberosum. Joining them does not create a new botanical species. In practice it is one jointly cared-for plant whose above-ground fruit and underground tubers are harvested at different times. That sequence is the attraction: tomato development is visible, while tuber formation is revealed at the later harvest. Quantity depends on cultivation and development.

Unpack and plan an accessible place

Carry the pot and support the long stem when unpacking. Inspect root ball, existing support and ties before moving the plant. Slowly moisten dry soil and remove water collected in the outer pot. This portrait follows cultivation without assuming particular fruit at arrival. Plan a place where the root zone is reachable for watering and tomato shoots for inspection. A narrow passage or unstable decorative cover complicates both. The grower recommends a large pot or, preferably, planting in vegetable garden or greenhouse soil for further development. The pictured styling is an example, not fixed delivery contents.

Sun and frost-free warmth rather than a dark kitchen spot

A warm, sunny place sheltered from wind suits tomato cultivation. On terraces and balconies the pot must be stable too; a tall exposed crown catches wind. Regular greenhouse ventilation prevents unnecessary heat build-up. After protected cultivation, gradually acclimatise to stronger sun and outside air. Move permanently outside only after frost risk in reliably warm weather. A sunny afternoon says little about the following night. A kitchen picture can show the plant beautifully but cannot replace sufficient growing light. PotaTom is a frost-sensitive vegetable crop for the warm season, not a basis for unprotected winter cultivation or continuous indoor harvests.

Give roots room and guide the tomato securely

Choose a roomy container with clear drainage holes or suitable garden or greenhouse soil. Vegetable soil should retain moisture while draining excess. Compacted wet soil is as unsuitable as a small root ball that constantly dries between checks. Set a stable support that carries the plant while allowing watering access. The manufacturer recommends a stake or fixing to wire. Tie the tomato stem loosely with soft material and check as it grows. Tomatoes do not attach themselves. In beds, allow free space around foliage and access from the side; the actual crown determines space needed. Avoid squeezing it between neighbours when tending shoots or picking fruit.

Supply the root ball reliably without standing water

Feel the substrate and compare container weight rather than fixing a watering day. When needed, water slowly at root level to reach soil evenly. Surplus must drain freely; a closed cover must not form a reservoir around roots. Keep the root ball evenly moist without standing in water. Check more in sun and wind and allow for lower use on cool days. Strong swings from a dry root ball to abundant watering can encourage tomato cracking and other supply problems. A suitable potassium-rich fertiliser used according to its directions helps tomato fruit development. Already fertilised soil counts too. More fertiliser replaces neither light nor reliable water; dosage follows the actual product.

Distinguish PotaTom shoots before removing them

The grower specifies particular care: remove tomato side shoots and above-ground potato shoots. This differs from a compact bush tomato whose side shoots normally remain. Identify the shoot before acting. Tomato side shoots arise in the angle between leaf stalk and main stem. Selectively remove unwanted young shoots without randomly removing leaves, main stem or flower clusters. Above-ground potato shoots are also removed following the grower’s advice. Keep the plant guided on its support. Under glass the manufacturer recommends gently tapping a branch or flower cluster to aid pollination. General tomato guidance confirms that gently moving open flowers can help, without promising a fruit from every flower.

Pick tomatoes first, then examine the potatoes

Watch fruit development and pick individual ripe, fully coloured tomatoes without pulling the whole truss. Weather, light and care determine maturity; a photograph with different fruit colours sets no binding harvest date. PotaTom potatoes are harvested at the end of the tomato season. Once tomato harvesting is finished, the grower recommends cutting the above-ground stem and first leaving the underground part in soil to mature further. Actual development matters when lifting, not a fixed countdown. Loosen soil and lift tubers carefully. A container can be gently emptied at harvest’s end. Discard green potatoes and do not use them. Store only dry undamaged tubers in a dark, cool, frost-free place. Fruit count, tuber yield and storage duration are not promised.

Notice changes and end the crop cleanly

Drooping foliage calls first for checking root-ball moisture, drainage and current warmth. Do not automatically add water to already wet soil. Inspect leafy shoots and leaf undersides regularly. Grafted tomatoes can still suffer above-ground pests and diseases; joining to a potato does not replace observation. Examine spots, soft tissue or rapidly dying shoots more closely. Clean pots and supports for the next crop and rotate the bed location away from tomatoes and potatoes to avoid accumulating soil-related problems. Development slows on cooler days. Decide in time before frost about remaining harvest. The PotaTom concept removes neither light needs nor regular work on root ball and shoots.
