Dig out and remove entire mounds (remember, they go deeper than they seem). For less severe cases: Physically remove mounds. Keeping them under control will ensure comfortable gardening for all. Fire ants can be a painful pest to have around for you and your plants. Solutions: Caution: fire ants are venomous and cause painful bites which can be fatal in the case of a rare but significant allergy. For serious cases of fire ants, consider hiring a professional. Some ant baits are only available to professional exterminators. These parasitic flies attack invasive fire ants. Introduce or promote beneficial phorid flies to gardens. Look for products that contain Indoxacarb. Apply the bait during a dry evening so the ants can forage for it at night. For a chemical solution, broadcast insecticide bait formulated for fire ants in the area around a mound. Pour citrus oil, which is toxic to fire ants, down their holes.
If there’s not much space within the canopy for light to reach the center of the tree, you can trim away some excess foliage to make windows for light to shine in. Trim these back to the branches they stem from as well. These branches will become an issue because they can effectively block out light and air from inner branches. Try to find all of the branches that grow either directly up (that are not the primary trunk) and those that grow directly downward. These branches or leaves will be too heavy and grow downwards, so this can be trimmed back if necessary. Next, be on the lookout for extra long branches or leaves that may not be able to support a lot of weight. Snip these off at the branch collar, where the branch intersection is, without scoring the main branch. Look for pests, irregular growth patterns, and brittle branches or leaves. How to Prune To prune your Nikko fir, first cut away any dead, dying or diseased branches. It’s also a good idea to wear gloves while pruning to avoid any splinters or cuts in general. For very tall branches that are out of safe reach, use a pole saw with the necessary safety equipment. While smaller plant shears and garden scissors may not cut it (pun intended), handheld clippers, pruners and loppers will certainly help out. Tools In order to prune your Nikko fir properly, you’ll need the proper pruning tools. This is why this part of the Nikko fir needs to be pruned in good time.
While most of the Nikko fir won’t need to be pruned until they develop some substantial height, sometimes their branches get a little carried away in the wrong direction.
