Gardening Questions And Answers
Anthracnose is the most common foliage disease that afflicts hostas, according to the Iowa State University Extension. Anthracnose is a fungal disease that causes irregular white to light tan spots with a brown border. As the disease progresses, spots broaden and split, giving leaves a disheveled, tattered appearance.
You can plant hostas all year round, but spring and autumn are preferable. It’s best to avoid planting hostas in mid-summer, when temperatures are high and the water table is low, as this can prevent the plant from establishing well. Mid-winter is also a bad time to plant hostas, as the ground is cold and […]
The most frequent cause of brown edges on hosta leaves is drought stress. The leaves usually begin to droop or wilt before the problem becomes severe enough to cause browning. Increase watering so the plant receives at least 1 inch of water weekly, and cover the soil with a 2-inch mulch layer to help conserve […]
Growing Hosta in Water is easy and fun! Plant it in transparent glasses and jars and have a stunning display of this ornamental plant! They are extremely easy to propagate by division, but surprisingly that is not the only way to multiply them–You just need a leaf-cutting to create a whole new plant!
The main reason gardeners cut their hosta flowers is to conserve energy – or appropriately distribute energy. It’s similar to how tomatoes are commonly pinched back! Gardeners will remove the side shoots (or suckers) on tomatoes so the plant can use its energy to produce larger, more nutritious fruit.
Sooty mold – Common hosta diseases include sooty mold, which is often found on hostas planted under trees affected with sap-sucking pests, such as scale or aphids. The pests produce a sugary excrement, which drops on the plant and attracts the dark, unattractive mold. Sooty mold is unsightly but usually harmless.
Hostas require minimal maintenance, although some light pruning keeps the plant productive, while improving the hosta’s health and encouraging lush foliage. Cut off any yellow, dead or damaged leaves with shears. Prune back all the dead foliage to the base of the plant after it yellows and dies back naturally in fall.
Hosta flowers are only open for one day, so they are engineered to be self-pollinated (the pollen is ripe at the same time the pistil is ripe to accept it). So unless you protect the flower from self-pollination, many of the seedlings will be self-pollinated or pollinated from other flowers on the same plant.
When & Where to Plant Hostas Soil Conditions: Hostas can survive in a wide range of soils but prefer a rich, moist soil, high in organic matter. Correct Spacing: Depending the variety, space plants 1 to 4 feet apart. Planting closer with allow the plants to fill in faster creating a ground cover of hosta.
