As indoor plant lovers, we want nothing more than to see our plants thrive but
sometimes their enthusiasm can become unruly for their space and may even
result in them outgrowing their pots too quickly. Although we can’t prevent
their growth while keeping them healthy, we can slow the growth down enough to
be manageable. Here are a few recommendations on how to contain and maintain
your plants for that indoor lifestyle.
Prune the leaves and branches
It is recommended to prune away the scraggly leaves and dead stems of your
plants for general maintenance and to keep them looking tidy. However, also
removing the larger healthy ones will not only contain the overall size of
your plant but divert energy into growing the smaller ones and promote new
growth.
Start pruning from the top and sides of your plants as these are the areas
that take up the most space. If your plants are particularly bushy, don’t be
afraid to be ruthless. Most can take losing up to a third of their volume or
more and still be healthy.
Pruning will also help tame your plants to either grow taller or wider
depending on your preference. You can do this by focusing your cutting around
the areas you don’t want and leaving alone the areas you want to maintain and
expand.
Prune the roots
Like pruning the top of your plants, pruning the roots will also divert their
energy into new growth. However, an added benefit of pruning the roots is that
it slows down the rate of nutrient absorption from the soil, which in turn
slows down leaf and stem production over a longer period.
If your plants are tightly packed or pot-bound be careful to not force the
plants out as you may accidentally tear the roots and stem creating
unnecessary trauma. Instead, you will want to break up and soften the soil
around the roots by gently pocking holes into it with a gardening tool or your
fingers.
With clean and sharp secateurs, cut away any roots that look dead, smell bad,
or feel wet and squishy to the touch as these can spread harmful bacteria and
may infect your other plants. You will want to trim away at least a third of
the smaller outer roots to be most effective at slowing down growth, but
ensure that you avoid the larger, thicker ones as these are vital for your
plants’ health.
Colder temperatures and less sunlight
Most indoor plants will thrive during the warmer months but go dormant during
the colder ones. During the dormant cycle, your plants will conserve energy by
slowing down growth or even temporarily stopping it altogether. You can
simulate this by moving your plants into a room that has less light or is
colder in temperature.
Be mindful that your plant needs at least eight hours of moderate sunlight a
day to survive. If the leaves become unusually lighter in colour or your
plants start wilting, you will need to increase this for their general health
and well-being.
