Giving a plant to someone without a green thumb can be like
giving a pet to someone who isn’t an animal lover.
“How long potted plants remain attractive depends on the care you
give them,” said Jim Crawford, the University of Georgia
Cooperative Extension coordinator in Jefferson County.
Crawford says the keys to successfully growing plants lie in how
much water and light you give them.
“Large plants in small containers dry out quickly,” he said. “And
the low humidity from the central heat in most homes increases
soil drying.”
Keep soil moist
To make sure your potted plants don’t dry out, he suggests
checking the soil daily and watering the plant if the soil feels
dry to the touch.
“You don’t just check the soil surface,” he said. “Often the
surface will feel dry when the soil around the roots is still
moist.”
Push about an inch of your finger into the soil. If it feels
moist, don’t water the plant, he said.
Over-watering can promote diseases
Overwatering can be just as damaging to houseplants as
underwatering.
“Root diseases can develop anytime the roots are stressed with
too much fertilizer, root wounding and poorly drained soil,”
Crawford said.
Signs of root diseases include plants wilting, the death of
individual branches and the yellowing of lower leaves.
Crawford says there’s a “fine line between too little and too
much water” when it comes to houseplants.
“As a rule, the longer the soil stays wet, the greater the
likelihood of developing root rot,” he said.
He recommends using the amount of water it takes to cause some
water to drain from the pot’s bottom.
During the holiday season, houseplant pots are often decorated
with colorful foil. Poke a hole in the foil on the bottom of the
pot to ensure the plant can drain, he said.
“After you make a hole, place the pot on a saucer to keep excess
water off your furniture,” he said.
Discard water that collects in the saucer. “Don’t reuse that
water or let the plant wick it up,” Crawford said. “This can
restrict root growth, causing poor plant performance.”
Let the sunshine in
The other key to healthy indoor plants is making sure they get
enough sunlight.
“Most plants need high levels of indirect light,” he said.
“Usually, the brighter the better.”
Signs of insufficient light include loss of foliage, weak
appearance and spindly, stretched branches.
Sudden temperature changes are also harmful to houseplants.
“Avoid fast temperature changes by keeping plants away from doors
and heating or air-conditioning vents,” Crawford said.
It’s not just energy wise to turn your household thermostat down
during winter months. It’s good for your houseplants, too.
“Turning down the temperature at night to between 60 and 65
degrees can actually prolong the life of flowering plants,” he
said.
Flowering and foliage plants can make great holiday gifts. Just
make sure the recipient is a plant lover, or your gift may be
short-lived.
