Can Amazon Sword and Pothos Grow Together?

Amazon Sword and Pothos share a workable water window around 22 to 28 °C, pH 6 to 7.5, and 2 to 15 dGH.

Both plants are comfortable in freshwater, so salinity is not a meaningful obstacle.

Both prefer moderate flow, so circulation can be planned as one steady pattern.

Their light and CO2 needs are close enough for one routine: Amazon Sword does best with moderate light and no added CO2, while Pothos does best with low light and no added CO2.

Both plants naturally lean toward the background, which is why spacing, pruning, and final mature size matter more than they do in a more staggered planting mix.

Amazon Sword reaches about 50 cm tall by 40 cm wide, while Pothos reaches about 100 cm tall by 50 cm wide. Use those mature sizes for the layout, not the small nursery portions you bring home.

Shade is worth watching, but it is usually manageable through trimming and a little spatial separation.

Amazon Sword is typically rooted in substrate with nutrient-rich substrate preferred and feeds mainly as a root feeder. Pothos is typically attached / wedged to hardscape with no substrate required and feeds mainly as a water column feeder. That difference can make the pairing easier to arrange than two plants fighting for the exact same root or attachment zone.

They can share the space, but the scape will stay cleaner if you leave more room than the labels alone might suggest.

Amazon Sword brings moderate growth, low maintenance, and beginner difficulty. Pothos brings fast growth, low maintenance, and beginner difficulty. If one grows much faster, trim that plant before it starts making the other look like the problem.

The practical watch-outs are that both plants tend to work in the background, so spacing matters more than usual; and that you will want to leave more room than usual for mature spread and routine thinning; and that the layout needs a little thought so one plant does not slowly dim the other; and that their substrate preferences are different enough that rooted nutrition should be planned deliberately; and that growth pace and maintenance rhythm are uneven, so the stronger grower can dominate if pruning slips.

The strongest reasons to try the mix are that they share a workable temperature window around 22 to 28 °C; and that their flow preferences sit close enough to tune one layout around both plants.

Use this pairing when you are willing to manage the scape, not when you want a plant-and-forget combination. Start with more spacing than you think you need, then adjust once both plants show their real growth pace.

The simple success test is whether both plants still look healthy after the faster grower has been trimmed several times. If one keeps declining after routine care, the layout is probably asking too much of it.
