Orchid Repotting Guide

 

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. 

 

When to Repot

 

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.

 

Selecting the Orchid Pot

 

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 without 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.

 

Potting Mediums

 

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.   Premium pottting 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. 

 

Start Repotting

 

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.   At this time it is beneficial to add a rooting hormone to the water.  Dyna-Gro K-L-N is recommended, especially if your root system is struggling. Once your orchid is ready to go 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.

 

Filling the Pot

 

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.  Dyna-Gro K-L-N is recommended for this process.  Your orchid should be fed with K-L-N for six to eight weeks after repotting.
