Today's Pond Q&A

Today's Pond Q&A

In this issue:




Carolyn I have had a pond for a year and half and there has been
no young fry. Four of the fish are about eight inches long. Is it
possible that all my fish are the same sex? I live in south
Jersey and my fish made out fine during last winter.

It is 60 gallon pool and about 2 feet deep. I installed a 12 inch
airstone and it did freeze over a few times. I spend the winter in
Florida so I don't know how long it froze over. I only have my
nephew's word

Thank You

Gee, Carl, consider yourself lucky! Especially considering your
pond is only 60 gallons, you wouldn't want a population explosion
in there. it generally takes fish about 3 years to come into
sexual maturity, and this is not a hard and fast rule, but I am
guessing you have goldfish and not koi. When they are about 12"
they will be acting differently.

The size of the container can have something to do with it also.
the fish give off hormones that will limit their growth and
maturity in a small size container. If they were in 6,000
gallons, they would have spawned by now in all probability. To
have more fish in the 60 gallon pond would probably mean oxygen
starvation for the larger fish, and possible death. Guess they
want to survive.

I enjoy your Question and Answer emails, keep them coming.

I have a question on dividing lily bulbs. When is it ok to
divide the bulb, without harming the whole thing and how do you
divide it?

Thank you for your info.

Hi, Linda,

Lilies can be divided either in the fall or spring. Spring is
possibly the best time, but either will do.

To divide, make sure you cut with a sharp knife so there are no
ragged edges. Take the plant out of the pot and rinse all the
soil (or potting medium) off, then cut pieces with root and
growing tips. Plant these up separately in new medium. I don't
suggest putting soil in ponds so look into using a soilless mix
or pure clay for any submerged pond plants.

In the spring, start putting fertilizer tabs into the pots as
soon as the water warms. It is for the fertilizing that spring
makes the best time to divide. To fertilize in fall would
encourage growth too late in the season.

Lilies are heavy feeders. In the fall, as during the year, you
could use Microbe-Lift Ensure to encourage good root growth (not
a fertilizer) and enable the plant to better use the nutrients
that are in the water.
