What To Look Before Buying Buying

We can’t simply try any fertilizer on flowering plants. They are more sensitive and delicate. How to choose the right one could be a puzzling task for growers. But you can find one that is perfect for your plant through proper research. What should you think before choosing any compost? Here’s a few deciding factors that can help you to determine the best match for your plant

Check  NPK of Fertilizer for Hibiscus Plant

By far you know fully well that hibiscus requires a high ratio of potassium and nitrogen. So, before buying any product, double-check its last number. It should be higher. This plant bears a number of flowers that need potassium as it essential for bloom formation and color vibrance. However, don’t buy those products with extreme potassium ratio. Extra potassium may result in plant damage or even other plant damage in your garden. The ratio of K should never exceed beyond 30. Under 30 is the right number. But it’s more a matter of experience rather than guess. You can observe your plants well according to temperature

Check Soil PH

What should be the right PH for your hibiscus? It’s important to know!

For ideal growth, the PH of soil should be between 6.5 to 6.8. Before planting and fertilizing, test your soil for this factor also. Sometimes gardeners apply fertilizers and don’t get expected results. They think the compost might not be of good quality. But the reason is something else. It could be the PH factor of soil that could affect your plant growth negatively.

If you find soil low in Ph then go for fertilizers that could optimize this value from 6 up to 6.8.

That’s really a contributing factor. So, consider it well before seedling.

Check Other traces of Nutrients

Make sure, your fertilizer should be a combination of traces of elements like copper, magnesium, zinc, molybdenum, and iron. Flowering plants like hibiscus need more energy from the soil. It’s possible only if you feed them with extra nutrients. Check the label of the chosen product and search whether your fertilizer includes these traces or not.

When To Fertilize Hibiscus

It mainly depends on what type of fertilizer you prefer for your garden

Whether you prefer the slow-release formula or fast-release formula.Important to note that this plant needs fertilizer frequently to grow well. But make sure overfeeding can be dangerous. So, follow the instructions written on the label of your chosen product well to avoid any mistake.

For slow-release formula, you need to fertilize your plant 4 times in a year

  • Early spring near march
  • After the hibiscus tree finishes its first round of blooming
  •  Midsummer in June or July
  • Early winter in October or September

For a fast release water-soluble formula, you can use it after every 2 weeks in the growing season, before growing season and in the fall.

However, you need to understand well when your plant needs fertilizer or not. Each plant has different needs accordingly. So, get the advantage of your observation and experience as well.

Tips of  Fertilizing  Hibiscus

Fertilizing this plant is pretty simple, but there are few tips that can help to do this without any hassle:

  • Always fertilize out of the edges of the tree canopy. In this way, roots will get more food to grow well. Growers often do the mistake of putting fertilizer near trunk that does not reach the roots properly
  • If your plant is not bearing enough flowers, it might be due to overfeeding. To lower down this effect you can add phosphorus to the soil. Surprisingly, blooms will get back.
  • Water your plant thoroughly after fertilizers that are granules and spikes mainly. Though it’s not needed for water-soluble products.

Conclusion

Selecting the best fertilizer out of hundreds seems to be tricky. But with knowledge, research, and experience you can use one that is a perfect fit for your hibiscus.

All of the above products are tested personally in our nurseries. You can choose anyone without any doubt. It’s time to wow your friends and neighbors by showing your blooms.

Hopefully, they will also love to learn from your experience.
