Best fertilizer for clematis vines – Buyer’s guide
Finding a “one highly effective” solution for heavy feeders like clematis is a hard nut to crack. Like most trees, shrubs, and flowering plants clematis need nitrogen, phosphorus, potassium, and traces of some essential nutrients to grow well. To simplify the fertilizing hunt I have broken it down into a few cases for better understanding.
If the clematis vine is not blooming
If the clematis vines look fine but are not blooming as they should it’s better to invest in some bloom boosters like Espoma organic flower-tone bloom booster and Schultz bloom plus fast-acting water-soluble plant food.
If it’s weaker in the roots
If it’s not growing and spreading properly, it’s highly unlikely that their roots are strong so in such circumstances, Jobe’s organics rose and flower granular plant food and Miracle-Gro performance organics all-purpose plant nutrition granules would be better options.
If their growth is slow
The unavailability of nutrients is mainly the reason for slow growth. For this problem, a general organic health booster is enough to fast forward the growing process. MicroLife hybrid 20-0-5 organic biological fertilizer, deco scrap rose and flower plant food, and Schultz bloom plus fast-acting water-soluble plant food are not disappointing options.
If it looks dull
If the clematis is growing well and it’s blooming as per your expectations but it looks dull then you probably need to fix the watering schedule. If the watering schedule still hasn’t taken the dullness away then a mild organic fertilizer once a month would not be a terrible choice.
In general, organic slow-release or continuous-release fertilizers are always great for flowering plants as the flowers are usually growing around in public places so using toxic chemicals in such areas should be avoided.
Remember! You can only find the cure for the problem when you know what the problem is. Sometimes it gets difficult to identify the issue so before going on a fertilizing hunt it’s better to get the problem identified by a professional.
