Growth Pattern of Hostas During Spring

Leaf Growth During Spring Season

On being exposed to a temperature of above 40 degrees Fahrenheit, hostas begin a new stage of growth. This stage is often known as the bullet stage.

The warm weather causes the swelling buds to respond, resulting in the growth of about three leaves at first. In warmer areas, leaves will grow even more vigorously. If the soil is moist and well-drained, new leaves continue to grow from the crown until a a little mound of foliage is formed.

The crown is vulnerable to rot, however, which makes it necessary to remove any piled soil or mulch near the crown. Proper air circulation is necessary for the crown to stay safe from any bacterial or fungal infections. Such infections can hamper leaf growth in hostas.

Growth of Roots in Hostas During Spring

Roots of hostas can retain moisture and nutrients for a long time, so sometimes they do not grow immediately after leaves emerge. It might take about a month for the growth of roots to commence. Roots may respond faster when exposed to warmer climates and high soil temperatures.

Old root tips need a fertile soil with plenty of organic matter. These tips grow along with the new structures to supply nutrients to the leaves above. A large area for transpiration can help the roots to grow up to several feet. However, roots need to stay moist during this stage. Lack of moisture can cause drought stress in hostas, causing them to die back/go dormant.
