As with usual feeding rules, don't fertilise in Winter, or recently repotted and new plants for a good 3 to 6 deals months.

If your plant's not producing new leaves don't feed at all.

Temperature
The Rubber Plant will be quite happy to grow in a broad range of temperatures between 10°C (50°F) to 29°C (85°F).

If you go hotter, the leaves will lose some of their turgid appearance. You can go as low as 4°C (39°F) in Winter if you have to, but your watering must be spot on. If you've overwatered at this temperature you'll kill the plant quickly!

Repotting
These plants grow quite big even if their pots are tiny.

These plants grow quite big even if their pots are tiny. However there will still come a point where the growth will slow down or even stop. You then have two choices, either leave it where it is and top dress instead.

Topdressing means scraping off the top inch or so of old soil and replacing with fresh compost which introduces fresh nutrients and beneficial microbes back into the old tired potting soil.

The second choice is to repot. Repotting a Rubber Plant is quite easy if it's not to heavy. All you need to do is move it into a bigger pot using a standard potting mix. If you're new to houseplants we have a more extensive repotting guide just for you.
