House plant over growing - Knowledgebase Question

I had this house plant for three and a half years but after moving to a new home 6 months ago it grown 3x the size. I kept it in my covered porch over the summer but now that it's getting cooler it's back in the house. Should I repot it into a larger pot?

There are at least 2 different kinds of plants here, Dieffenbachia and arrowhead vine:
Dieffenbachias (Dieffenbachia)
Arrowhead Plant (Syngonium podophyllum)

Dieffenbachias are prone to leaning over when they get taller. They can be staked, trimmed, or just left to dangle.

The other plant, being a vine, will eventually start climbing around, or leaning over, depending on the setup. I might repot this pair in the spring but they look healthy and happy at the moment, for potted lower-light specimens. Dieffenbachia usually dies more often than it lives. Keep up the great work!

When moved back inside and usually into lower light, the growth rate of plants tends to slow down in winter. Thus, repotting now is probably not such a good idea. It certainly looks like the pot is plenty big enough.

I do recommend that you prune back both the Dieffenbachia and the vining Syngonium. They tend to become unruly when not pruned. New growth will emerge on each stem just below where you make the pruning cut.
