Planting
The best time to plant Blueberry Muffin Hosta is spring. This is when the weather is more favorable, and it will be much easier for the plant to take root in its new location than if you planted it in the summer heat.
Another good time is early fall. This is when the ground is still warm from the summer sun. You should plant the hosta at least 1 month before the first frost.
The best place for Blueberry Muffin to grow is in full shade and loose, nutritious soil. Also, make sure that no water collects in the area.
As for spacing, Blueberry Muffin Hosta should be planted 3-4 feet apart. This variety is medium-sized and requires plenty of room to develop. Also, avoid planting it too close to the trunk of large trees.
When planting, do not dig the stems deeper into the ground. The place where the stems connect to the roots should be at ground level. After planting, mulch the root zone with organic material about 2 inches thick.

Light requirements
Blueberry Muffin is a blue hosta, and, as you know, such plants grow best in full shade. So you have to plant this plant in a place with shade all day. So you can count on a very intense blue color.
It can also tolerate up to four hours of direct sun in the morning. In such a spot, Blueberry Muffin will still be blue and grow more vigorously.
You must avoid planting it in full sun because it will make the leaves look pale and greenish. In the summer sun, the leaves will get sunburned and look terrible.
Soil
Blueberry Muffin Hosta can grow in most soil types, but if you want to give it a good start, you must improve the soil a bit. This is especially true if your soil is too clay.
The best method to change the quality of the soil is to use organic matter. Before planting, apply about one bucket of compost and mix it with the native soil. Please buy quality compost made with the right technology from local suppliers.
Also, ensure your soil has a pH of 6.0-7.0. Use a soil acidity kit for this purpose. Use acidifiers to lower the pH and garden lime to raise it.
Watering
This hosta, like most others, needs to be watered. This is especially true in the summer heat.
The best way to check if watering is necessary is to feel the soil with your fingers, and if it is 2 inches dry, you should water. When watering, use about 1 gallon of water per plant.
You shouldn’t water according to a schedule because you might over-water the soil, and the hosta could rot. If this happens, dig out the bush and remove the rotten tissue. Then, wash the wound with an aqueous hydrogen peroxide solution and plant the hosta in well-drained soil.
Propagation
The easiest and fastest way to propagate Blueberry Muffin Hosta is by dividing. To succeed, divide the rhizome only when it already has 10 buds. The best time of year for dividing a hosta is in the spring.
Dig up the shrub and clean the roots from the soil. Use a sharp and sterile knife to separate. Divide the rhizome so each part has at least 3-4 buds.
Powder the wound with fine ash and plant the new plants in well-drained soil—water with a small amount of water.
Problems
Usually, problems with Blueberry Muffin Hosta are infrequent, but sometimes, it can get sick. The most common disease is leaf spot.
Different pathogens cause this disease, but the result is the same: small brown spots appear on the leaves. Over time, the spots become more and more numerous, and the leaves may die.
To cure the hosta, spray the leaves with a multi-purpose or copper fungicide. Repeat the spraying after two weeks.
Since Blueberry Muffin leaves are pretty hard, these pests hardly damage them. The exception is the young, soft leaves that appear in the spring.
To get rid of slugs, use a variety of traps. But the best effect on these pests is iron sulfate granules.

Fertilizer
If you want to speed up growth and increase your plant size, you can fertilize a bit. Fertilizing is also essential if the hosta is growing under a large tree because the tree reduces the number of nutrients in the soil.
The best fertilizer is a slow-release mineral fertilizer in pellet form. The fertilizer can be multi-purpose and contains all essential elements.
The best and only time to apply the fertilizer is in early spring. Avoid fertilizing in the second half of summer or fall, as this can cause new shoots to grow, which can be damaged by early frosts.
