Why did my blue hosta turn green

Keep blue hostas in shade to preserve their coloring The blue color is nothing more than a layer of wax called bloom that wears away over the course of a growing season with exposure to sunlight, heat, or rainwater.

Why are my variegated hostas turning all green?

Some variegated plants are hybrids not mutations. Their unique foliage arises from crossing two different species of plants. The offspring contains genetic material from both parents. If their leaves suddenly change from variegated to solid green it is not a reversion but rather a sport (mutation).

Do blue hostas prefer sun or shade?

In general, blue-leaf hostas require shade, while those with fragrant flowers, gold or yellow foliage or slight white variegation can tolerate more sun. If the hostas you try suffer in the south side of your garden, these tough plants are easy to move to a more suitable, better-shaded location.

How often should you water blue hostas?

Hostas are drought tolerant, yet like moist well drained soil. If the weather is hotter, increase the watering to three times per week.

What does Epsom salt do for hostas?

What happens if hostas get too much sun?

Hostas are shade-loving plants. They'll do well in full shade or where they get some morning sun, which is less harsh. Too much sunlight causes leaves to scorch and bleach out. Hostas like even moisture, too, which is another reason sunny spots don't work — they tend to dry out faster.

How long does a blue hosta take to grow?

As a rule, hostas start to grow quite late in the spring, but quickly fill in their allotted spots in the garden. Hostas may take 2-5 years to reach their mature size so keep this in mind when planting.

Can reverted variegation come back?

IN THE CASE OF REVERSION: If your variegated plant starts to revert, the best thing to do is remove the reverted branch back to where it was last variegated. Once a branch begins to revert, it's unlikely that it will grow variegated leaves again from that section.

Can you make a reverted plant variegated again?

Once a plant reverts back to green it is not possible to again reverse it back to variegated colorings. Variegated plants will have limited amounts of chlorophyll in their leaves because of the lack of green coloring. Less chlorophyll in a plant equals less energy, which is needed for photosynthesis.

How do you encourage variegation?

Place the plant in full sun to encourage variegation. Variegated plants need more sun than solid green plants because they don't have as much chlorophyll to absorb sunlight. If you're growing a variegated plant, leave it near a sunny window or a bright spot on your property so it absorbs enough sun to stay healthy.

How to Care for Hostas

Apply a well-balanced, slow-release fertilizer after planting or when growth emerges in the spring.
