If you are a pond keeper, it is essential to ensure that you keep certain types of poisonous trees out of your fish pond. The vast majority of species shed their leaves, especially during the fall season. The last thing you want is for koi fish and other pond fish to eat the leaves, as they fall into the water.
Even if the leaves are not toxic, increased levels of organic matter dripping into or blowing into the pond is bad news; The leaves eventually decompose on the pond floor. vegetation degradation increases ammonia and carbon dioxide levels; Nobody wants that!
The net cover is a viable solution but in my opinion detracts from the overall look and feel of the pool; Needs must in many cases however!
You might think I’m fine because I have a pond deck skimmer to remove leaves. Although a pond skimmer will remove leaves, it may not do so in a timely manner. Koi are curious, hungry creatures that will investigate any new pond presence pretty much instantly!
The right selection of tree species will certainly provide a welcome respite for koi, goldfish, frogs, and other aquatic life from a hot summer day, as their shade prevents the water from heating up quickly.
The welcome shade helps block UV rays, which in turn helps control the build-up of hanging moss and weeds. Cold water helps oxygen dissolve from the atmosphere into the water more easily.
When choosing trees to place around a pond, avoid the following, or choose them at your own risk! Laburnum tree, bay, laurel, yew, and lime all cause problems. Other species, while not necessarily poisonous, have large root systems that eventually overlap your pond liner; Examples to avoid are poplar, willow, and sycamore varieties.
The following list is suitable for planting in backyards that have a fish pond or water garden:
* Some elm tree cultivars are a good choice because they don’t cast much shade and their root system doesn’t spread out like wild wire. The mountain ash has flowers of the older variety in the spring, followed by bright red berries in the fall that are almost obscured by the striking red foliage. Japanese mountain ash produces large orange berries.
* Crab apple trees are a fairly small type of tree and are a great choice for landscaping around a fish pond. Japanese crab apple and fragrant Malus Pink Perfection are good choices.
* Other good choices are hawthorn or mayse, especially if you need something really hard and heavy. Why not try Crataegus prunifolia for fall color.
*Swedish silver birch (Betula dalecarlica) is great if you’re looking for lighter foliage and bark that gets progressively whiter over time.
If you have an outdoor pergola, located near your pond and are looking to add some evergreen climbing climbers, be sure to avoid climbing climbers, such as ivy. These plant species are among the most toxic of all climbing species.
If you’re determined to choose deciduous and evergreen climbers, Silver Queen (Euonymus fortunei) is a great choice because it grows quickly and hardly ever blooms; Sometimes it produces flowers but you can easily prune it back.
