Q - Last year I purchased from you 50 Hornwort and 25 Anacharis. This year they
have taken over the pond almost. I need to thin them out. Should I pull them out
or cut them what would be best? THANKYOU. - RONALD
A - By growing & multiplying, these plants are doing their job of filtering the
water & removing nutrients & toxins. We suggest thinning the Hornwort by
pulling some out & cutting back or thinning them some. Too much plant life can
rob oxygen at night during the heat of summer causing fish & bacteria to
die from too little oxygen. - BILL
Q - I have a couple of tropical pond plants (Spider Lily & a Taro plant) that I have
had over the winter. When can I put them in the pond or is it even safe to do that
now? - WANDA
A - Here at the garden center, we have already put our tropical plants into the
pond. But keep an eye on the weather. Taro, in particular, does not like
temperatures much below 45 - 50 degrees F. If it is predicted to get colder, bring
them inside or into the garage for the night. - BILL
Q - Is it possible that the Anacharis in our pond survived the winter or should we
pull it all out & replace it? - KEN & BARB
A - Anacharis (Egeria densa) is a submerged aquatic plant used in water
gardening ponds. It competes with algae by absorbing a great number of
nutrients from the water. In our ponds at the garden center, the Anacharis
have survived for about 7 out of 10 years. If it is still green, it will soon start
to grow (as soon as the water temperature is warm enough.) We try to cut it
down to a couple of inches tall in late September, just before the water gets
too cold. This removes the nutrients stored in the plant. - BILL
