Helpful Hints for Raising Hostas

Hostas are some of the most popular perennials in the world. They are very easy to grow and are beautiful when raised properly. They are versatile and come in a variety of colors and leaf shapes. Let’s talk about some growing tips

Proper Nutrients and N-P-K Ratio

The proper N-P-K ratio for hostas is an N-P-K ratio of 1-1-1. Apply the fertilizer around the hostas, but away from the leaves and the crown as this can cause burn. Using a fertilizer with a slow release nitrogen is also very beneficial because hostas like continual release of nitrogen and nutrients. Other nutrients to make sure to supplement your hostas with is magnesium, which can easily be found in the pharmacy in the form of Epsom salts.  Hostas flourish when given magnesium, so mixing magnesium in the water that you use to water your hostas can be very beneficial. You can mix a couple of tablespoons of Epsom salts into the water that you are using to feed your hostas.

Do Not Overfeed Your Hostas

Make sure to follow the instructions on the fertilizer you buy and do not overfeed your hostas. Too much nutrients can be as bad as too little nutrients as it can lead to nutrients burn of your hostas’ roots.

Best fertilizers for Hostas

Plenty of Sunlight

Because hostas are very versatile, they can tolerate shaded areas. However, they flourish and grow much faster with more exposure to sun. Ideally you want to allow your plant to have about 5-6 hours of sun exposure per day.

Types of Hostas

There are so many different types of hostas out there – hosta gracillima, hosta crispula, hosta halcyon, hosta guacamole, hosta august moon, and hosta alligator alley – just to name a few.

Bottom Line

Again, I recommend buying the Osmocote’s fertilizer. Don’t fall into all the market hype of different fertilizers that do not provide quality ingredients to your ingredients. If you end up getting a fertilizer that is not on this list make sure to at least get one with the proper N-P-K ratio.
