The million-dollar question for serious gardeners is whether it is better to divide your hosta plants in late fall or the early spring. At our vineyard, we have massive perennial gardens which are home to hundreds of hostas. When you see me staring off into space while relaxing in one of the many sitting areas on our property, what I am really doing, is contemplating which hosta need to be divided, and where the gardens will expand into the next season.
From past experience, I have learned it is easier to “wrestle” the plant in early spring, when those tender buds are swelling through the warm spring earth. If I divide at this time, I don’t feel as though I am committing an act of violence against them. BUT, early in the spring, it is difficult to remember what that hosta looked like. You see, I am one of those gardeners who obsess over planting hostas so their colors, variegations, and shapes, will both contrast and compliment those around them.
For that reason, I am with the divide in the fall group! Yes, you will most certainly damage some leaves, and it may seem as though the plant suffered a setback, but in the next season they will “spring back” to put you in awe of the project which you completed.
Here is what you will need to get started:
- A wheelbarrow, shovel, cutting tool, some organic matter, and water. Start out by assessing which plants need to be divided, then decide where you will plant them. Keep in mind that hosta leaves will scorch in full sun, so be sure to select an area that gets only a few hours of morning sun.
- Next, dig around and below the hosta being careful not to damage too much of the root system. Lift the entire plant out of the ground and don’t be shy about asking for help if it is too heavy. With a garden hose, rinse as much of the soil from the root system.
- Now is the time to get tuff. You can take your shovel or cutting tool, and slice all the way through the roots, and divide the plant into one or more sections. If the roots are not too tangled, it is best to pull the sections apart by working with your hands.
- Next, add the organic matter or compost in the hole and replant one of the sections where you just dug it up. Place the other sections in your wheelbarrow and take to the area you will plant. Dig holes at least twice the size of your root system. Again, add organic matter or compost to the hole, and fill in around the plant.
- Be sure to water all generously and regularly.Another tip when planting is to either plant a “specimen” or in groups of 3 or 5 for an attractive look. If you have room, consider adding some companion plants such as Astilbe, Baptisia, Bleeding heart, Dianthus, or Pulmonaria (lungwort.)Above all, be patient. The hosta may not look very attractive at this time, but after it has had a long winters nap it will emerge in the spring looking as beautiful as ever!
