Your outdoor plants benefit from frequent applications of fertilizer, to
fuel fast growth. Soil conditions in your yard and garden may be less than
ideal. Heavy rains can leach out valuable nutrients.
Your indoor plants need nutrients, too. But, indoor plants need fertilizers
in a much different way. Let's explore what they need and when.........
Slow growth - Indoor plants grow much more slowly than outdoor plants.
Chances are, you do not want your plants growing quickly and wildly, even
if they could do so indoors. So, your indoor houseplants need far less
fertilizer. But, they do need some.
Pots and Containers - Moisture and nutrients available to your houseplant,
are limited to what is in the soil of the pot. As long as you do not overwater
your plants, the nutrients in the soil stay there until your plant slowly
consumes the nutrients. If you fertilize too often, nutrient levels can become
excessive, and harmful to your plants.
How and When to Fertilize
As the nutrients in the pot or container begins to be depleted, you will
need to begin fertilizing your houseplants. As with outdoors plant care,
the need for fertilizer will vary.
In general, fertilize houseplants once or twice a month...at most. Use a
liquid fertilizer or fertilizer spikes. Easy to use fertilizer spikes have
a slow release formula. You may need to insert new spike into the soil every
couple months. The package will tell you the frequency.
After applying fertilizer, observe the health and growth of your houseplants.
Adjust your fertilizer program over time, to achieve the level of growth
Liquid fertilizer can also be used for foliar feeding. Usually, this is not
needed for indoor plants. If you choose foliar feeding, use a diluted formula.
