Have you heard the term marginal plants before? Marginals are a plant for the
water garden that grows quickly. The quick growing marginal plants need repotted
usually every spring, dividing up this fast growing plant to fill other portions
of your water garden. You can divide up your fast growing water plants in the
fall before the cold winter approaches and succeed for the following year. When
the pot is too full of roots you will have to break up the roots with your hands
or with a knife for replanting.
It is also a good idea to wash off the roots and the plant itself by hosing them
down so you can keep any little pests or bugs under control.
When you are dividing up your marginal water plants and the roots seem to be
very small, cutting back the top green portions of the plant may be necessary in
order to allow the root system to ‘catch up’ to support the plant.
If you have fast growing plants that you seem to be forever replanting, it is a
good idea to line these large pots with burlap so that the roots can not grow
out into the water garden and start taking over your entire water garden.
Keeping your water garden plants under control, no matter how fast they seem to
be growing is going to be a task that you should keep after to ensure that your
water garden remains simple.
When replanting your fast growing water plants, be sure not to pack the soil too
tightly around the roots. Lightly patting the soil with your finger tips is
going to do the trick just fine.
Any portions of the plant the is exposed, or that appears to be a plant in a
growth stage should not be covered with soil so that it does not become mushy as
it is too wet under the soil area.
Keep in mind that plants that are fast growing, with a flower will spill seeds
in to your water garden. As the plant puts seeds into your water garden you
could end up with plants growing in the water garden in areas that you did not
Cutting back your water garden plants in the fall will cut down on the spaces
where any little bugs or pests might be hiding over the winter. Because these
plants are fast growing you will never notice the difference in the spring
months when the plants return from dormancy for the new growing season.
