Proper repotting techniques are key to the success of your orchid’s health. First,
you need to determine if your orchid needs to be repotted. There are several clues
that your orchid is ready to be repotted, even if it is a new purchase. Most orchids
like to be repotted every one to two years when the bark begins to break down.
If your orchid is left too long without repotting and the bark continues to break
down, this will lead to root rot, and eventually the decline of the plant. Another
clear sign your orchid needs to be repotted is when the new growth is starting
to grow on or outside of the pot.
Timing is critical when repotting your orchid. Never repot your orchid when bloom.
Orchids like to be repotted when new growth is active. This can be root or vegetative
growth. Most new growth occurs in spring and summer when the days are longer and
warmer. Repotting at the wrong time can lead to stunted growth, fewer flowers,
and decline in overall health of the plant.
Now that you have determined if your orchid is ready to be repotted and when to
repot it, you need to decide what to pot it in. Just because your orchid needs
repotting doesn’t mean it needs a larger pot. The root system of the orchid should
fit in the pot with doubling over. There should be about 2 inches of space around
the inside wall of the plant. This will allow for the next seasons growth. Orchids
need constant air flow for their root system, which is why slatted orchid pots
are highly recommended. Drainage in the bottom of the pot is also needed for root
health.
Due to the fact that there are hundreds of potting mediums for orchids on the
market it may seem difficult to select one. Only premium fir bark and New Zealand
sphagnum should be used for repotting. This will prevent premature breakdown which
will lead to root rot. The Off mix is an ideal potting mix for most orchids. It
is a medium grade fir bark mixed with various components for optimal root health.
New Zealand sphagnum can be used alone or added to the Off Mix for additional
water retention.
Now you are ready to repot your orchid. First, make sure you have a clean work
space and clean tools to work with to prevent the spread of disease. You want
to start by soaking your potting medium in water for at least an hour so that
it is completely saturated. The root system of your orchid should be soaked in
luke warm water for twenty minutes before starting. This will make the roots supple
resulting in less breakage. Once your orchid is soaked all the old potting medium
should be removed completely and discarded. You need to examine the exposed root
system carefully. This can tell you a lot about your watering practices. Roots
that are hollow and mushy are a result of over watering. Roots that are shriveled
and dry are caused from lack of water. These unhealthy roots should be removed
with clean sharp pruners. Only healthy, firm roots should remain intact on the
plant.

Orchid Placement Within the Pot |
Positioning the orchid in the pot appropriately is imperative to allow for new
growth. When it comes to repotting orchids are broken down into two groups, monopodial
and sympodial. Monopodial orchids grow from one central axis, such as a Phaleanopsis.
This group of orchids should be centered in the pot. Sympodial orchids have multiple
growth points, usually creeping along the surface of the potting medium like a
Cattleya. These orchids should be positioned giving the new growth room to grow.
The old growth should be snug against the wall of the pot giving ample space for
new growth for the following season.
Once your orchid is positioned you begin to fill the pot with potting medium by
stabilizing the orchid with one hand and filling the pot with the other hand.
The potting medium should be firmly packed in the pot. This can be done with a
clean potting stick or just use your fingers for smaller plants. The potting medium
should be an inch or so below the top of the pot to allow for watering. The orchid
should be stable in the pot. You may need additional staking to help with stability.

Feed your Orchid for Growth |
The final step is to feed your orchid with a growth hormone to stimulate rapid
root growth. Jump Start is recommended for this process. Your orchid should be
fed with jump start for six weeks after repotting.
