Can lead weighted, oxygenating plants simply be thrown into your pond?

Can Lead Weighted, Oxygenating Plants, Simply Be Thrown Into Your Pond?

The answer to this question is a definite NO!  There are many different bunched oxygenating plants that are sold in the aquatic pond plant industry and almost all are sold with lead weights. The idea behind this is that the weighted bunch can simply be thrown into your pond where it will sink down to the bottom and start growing.   However, this is simply not the case for two very good reasons.  Firstly, all oxygenating plants with the exception of Ceratophyllum Demersum (Hornwort) require at least 4-6 cm of established pond silt, clay or added aquatic soil in which to root in to.  This means that any lead weighted bunches added to new ponds or cleaned out ponds with no substrate or silt, will simply die off very quickly.   Secondly, many of the bunched oxygenating plants offered in the aquatic pond industry, are simply only suitable for certain types of water garden such as, large natural clay bottomed ponds and Lakes, so they will not survive when added to a small man-made back garden pond.

So, just to summarize, all lead weighted bunched oxygenating plants require silt/ substrate in which to root into, with the exception of Ceratophyllum Demersum (Hornwort).   Any oxygenating plants sold in pots or bare rooted will need planting up.   If you don’t have 4-6 cm of substrate, sediment or aquatic soil in the bottom of your pond, you will need to plant all your oxygenating plants (including those lead weighted), into aquatic baskets or aquatic planting bags.  Aquatic Baskets should always be lined with Hessian or cloth liners to stop the Aquatic Soil from seeping out.
