About Paul Robeson Tomato

Solanum lycopersicum 'Paul Robeson' · also called Paul Robeson tomato, black heirloom tomato · edible

'Paul Robeson' is a celebrated Russian heirloom 'black' tomato bearing dusky brick-red fruit with smoky, rich, sweet-tart flavour. An indeterminate beefsteak type, it needs full sun, staking and a warm season. ASPCA lists the tomato plant as toxic to pets, though the ripe fruit itself is non-toxic and famously flavourful.

Mature size: 1.5-2.4 m tall on supports as a cordon; spreads roughly 45-60 cm.

Indoor size vs how big it gets in the wild

Paul Robeson Tomato reaches its full size within one growing season — there is no "long-term" size, just how big it gets before you harvest or it dies back. Indoors and in a pot, expect 1.5-2.4 m tall on supports as a cordon. In the ground with no restriction it is a completely different plant — spreads roughly 45-60 cm. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.

Growth rate and years to mature

Paul Robeson Tomato is a fast grower. Realistically, expect a single growing season — it reaches full size in one year, then is done. Its feeding profile backs this up: balanced feed at planting, then high-potassium tomato feed every 1-2 weeks once fruit forms. avoid excess nitrogen, which favours foliage and dulls the prized flavour.

How to keep paul robeson tomato smaller

You are not stuck with the maximum size. For paul robeson tomato specifically, these are the levers, in order of impact:

Choose a compact or dwarf variety of paul robeson tomato from the start — that is the most reliable size control for an annual.
Grow it in a smaller container to naturally limit how large it gets.
For some crops, pinching or pruning the growing tips keeps the plant shorter and bushier.
Sow a little later or space plants closer if you specifically want smaller individual plants.

How to grow paul robeson tomato bigger or faster

Feed appropriately for the crop and never let it check (stall) from drought or cold.

Light is almost always the ceiling. The paul robeson tomato light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When paul robeson tomato outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for paul robeson tomato:
