Peace Lily - Why Do They Get Brown Tips
Did you know the Peace Lily or Spathiphyllum is a great plant for
a healthier
home and cleaning
indoor air?
Many reasons exist for tips turning brown.
- Fertilizer
- Over-watered or under-watering
- Pests
or any combination of these factors and others.
Throw into the mix the different varieties and its gets very confusing
on why plants get brown tips.
Varieties Grown for Flowers
Today, many varieties of spathiphyllum are grown.
Some are grown for the abundance of flowers they produce. But flowers
come at some expense. The cost? Nutrients that go to the flowers
do not go to the plant. When plants hold a lot of foliage, they
may require more water to support the foliage. You may notice lighter
colored leaves and if the plants dry out too much you can get browning
tips.
The older leaves at the bottom...If that is where the brown tips
are occurring. The leaves are not "pulling" food the same
way, new rapidly growing leaves do. Brown tips and leaf loss in
this case may be natural.
Foliage Varieties
What about varieties grown more for foliage like Lynise, Supreme
and Sensation. These plants usually grow in 10 inch and larger pots,
but may present the same problem in looks, but for a different cause.
In the nursery these plants are watered and fertilized on a regular
basis. They may be watered every day or every other day. All of
a sudden the plant is shipped to a nursery or garden center and
it isn't receiving the same treatment.
They may get less water and the fertilizers (salts) which are in
the pot are getting higher because of the reduced moisture and can
be burning the roots.
Speaking of under-watering, there are two ways (and probably more)
to do this. The first is just not watering the plant enough and
allowing the plant to wilt down before watering. A little droop
may be OK, but not laying on the ground. I will admit this is rarely
the case with house owners.
The second method is what I'll term "fake watering".
We think we water but we really don't. This occurs when the soil
has dried out, the soil may even be pulling away from the pot and
the plant is re-watered. The water is going to take the path of
least resistance and heads to the bottom of the pot. The soil may
become moist in areas but the root ball or soil mass doesn't become
sufficiently moist. It may be moist enough to let the plant perk
up but the soil is still too dry. Again, this can be salts or the
plant protecting itself by reducing the amount of foliage it needs
to support. Result - Brown tips.
Water slowly and not in one small area.
Over-watering can cause brown tips also. The root system is just
not able to use all the water you provide. The roots may be swimming
in water and rot off. Less roots means less leaves, and the plant
will usually begin by losing the oldest leaves first.
Too much heat is another possibility. You may be asking yourself
how can I have too much heat, it's 72 degrees in the house. That
may be true but a plant sitting next to the window can be heating
up more than you realize. We all have hot and cold spots indoors.
Why do I have brown tips on my Spathphyllum? There are many reasons!!!
Plants are great communicators and they really re-act in ways that
we can understand if we stop and look at the situation. Plants may
not tell us what is wrong BUT they do tell us to LOOK something
is wrong.
When you're looking for answers to WHY, on your plants, ask some
questions. I find many times that it is the little things that we
may not pay attention to that have caused the problems.
Did anything change in the environment?
Something as simple as - Yes we opened the house up after a long
winter to air things out. The temperature was still a little cool
but a light sweater was all I needed. Did the plants get a sweater?
- Did you move the plant?
- Has the watering changed?
- Is the plant new and getting acclimated?
- What is the root system like?
- What variety is it?
- Is the plant actively growing? Putting out new leaves with good
color.
ALL valid questions.
Don't assume that because you have some brown
tips that your plant may need to be repotted or need fertilizer.
It may be just the opposite. Let's look at flowers.
