Hostas: A perfect plant for beginners and beyond

The other day, my friend was complaining about how rugged her hostas were.  She mentioned how brown the leaves were and how they appeared to be dying even though they get adequate water.  I asked her where they were planted.  She mentioned that they were in the sun with landscaping rock around them.  “Ah!  I see the issue,” I told her.

                While hostas are one of the easier plants to grow, very good plants for beginners, there are still some points to note when you are looking to add hostas to your landscape.

                The first thing to consider is how much light does the area get.  Hostas will grow in full shade to full sun (even though they mostly prefer morning sun to afternoon shade).  A good rule of thumb is the darker the leaf, the more shade that variety of hosta needs.  Your gold/yellow/light green colored hostas are going to be the variety that you want to plant in your sunniest places.  I have ones this color in full, strong, southern sun and they are growing like weeds.  However, if you plant a hosta that likes more shade than sun in too sunny of a location, you will see stress in the form of browning leaves on your plant.  While hostas are easy to grow, they are particular about their sunlight.

                The second thing to consider is the amount of water they are receiving.  Hostas grow in almost any soil condition, including sandy soils, provided they receive enough water.  Hostas do well with about an inch of water a week (much like your lawn).  They don’t like to get too wet or too dry, so ensure they are planted in a well-drained spot.  If you do plant them in sandy soil, they take a little more water and will grow better if the soil is covered with mulch to keep the roots cool and moist.

                This leads me to my third thing to consider – mulch.  I’ve seen several people, including my friend, who grow hostas in landscape rock and then wonder why their plants are “dying” underneath with the under layers of their plants turning brown.  While I’m not one to say you shouldn’t use landscaping rock (it does look very beautiful in landscapes), it is hard on your hosta.  During the day, especially during the summer months, the rock heats up, causing heat to radiates upwards and is essentially burning the leaves of your hosta.  Hostas do better with cooler mulches such as wood chips or cocoa bean shells.  However, if you are set on rock, you can still plant hostas into your landscape.  Before you put your rock into your landscape, build a ring around your hosta.  Black landscaping edging works perfectly for this.  Build your ring out to just beyond your furthest reaching leaf (also known as the drip line) and then place your rock up to the edge, leaving the area underneath your hostas as dirt or you can add cool mulch.  This way you minimize the heat damage to your plant while still enjoying your landscape.

                While hostas are great beginner plant, they don’t come without some cons.  One is deer find hostas to be a tasty snack.  You’ll want to keep this in mind as you plan your hosta beds.  Second, slugs also like to feed on your hostas.  You can help cut down on the slug issue by sprinkling Epsom salt around your hostas.  The salt causes the slugs to dry up, while providing magnesium and other needed nutrients to your hosta.  Just be careful not to go overboard with the salt, as you could cause damage to your plant.  About ¼ to ½ cup, depending on the size of your hosta, is about all you need.


                If you take good care of your hostas, they will reward you.  Hostas have been known to attract butterflies, humming birds, and other flower loving creatures.  Start your hosta garden today and see what wonders you will be rewarded with.
