In a clump of hostas, a sport is a leaf bud that grows differently than the rest of the clump.
In the photo to the right, you can see the green sprouting in the clump of ‘Guacamole.’ Because ‘Guacamole’ is a hosta sport of ‘Fragrant Bouquet,’ the green is not a reversion. As listed below, there are various sorts of sports.
- Changing the position of cells between distinct tissue layers in an individual, e.g., a gold-margined hosta producing a gold-centered, all-green, or all-gold division.
- A change in the genetic make-up or physical appearance caused by mitotic recombination.
A reversion is a leaf bud that returns to the original mother plant in a clump of hosta. In the image to the left, notice the single dark green center of ‘Sum of All.’ The plant’s surviving leaves have returned to the gold of ‘Sum and Substance.’
What is a sport on a plant?
Have you ever noticed any sports in your garden or in others’? No, I’m not talking about sports like basketball, football, or cornhole; a’sport’ in the realm of botany and horticulture is a whole different ballgame! In botany, a’sport’ refers to a ‘genetic mutation,’ which has no explanation and no clear rhyme or reason for occurring. Sport is a genetic mutation that can happen to any plant at any time.
What is a hosta scape?
Hostas are low-maintenance perennials that are more commonly grown for their striking foliage than for their minor blooms. Some growers cut off the stalks, known as scapes, as soon as they appear, focusing the plant’s energy on vegetative growth and the formation of new clumps. If you want to do this, cut scapes as close to the crown as possible as the plant begins to produce, which can happen anytime between early spring and August, when many H. plantaginea hybrids bloom.
What is a hosta eye?
A sprouting shoot from the crown that can support anywhere from one (rare) to twelve (perhaps) leaves. Early in the spring, the new eyes appear as conical projections from the crown. Also known as divisions, but this might be misleading when referring to a newly divided plant. Hosta farmers will discuss the amount of eyes on their hostas, but keep in mind that a hosta with three little eyes may have less presence in the garden than one with one enormous eye.
What causes sport variegation in plants?
A sport or bud sport, also known as lusus in botany, is a portion of a plant that differs morphologically from the rest of the plant. The shape and color of the foliage, the flowers, the fruit, and the branch structure of sports can all be different. A random genetic mutation is widely assumed to be the cause.
Sports with favorable traits are frequently vegetatively propagated to produce new cultivars with the desired morphology. Such selections are prone to “reversion,” which occurs when a portion or all of the plant returns to its original state. The nectarine is an example of a bud sport, as at least some of them evolved from peaches. The red Anjou pear, Ruby Red grapefruit, and the ‘Pink Lemonade’ lemon, which is a sport of the “Eureka” lemon, are some common fruits that have resulted from a sport mutation.
What does Epsom salt do for hostas?
Epsom salt enhances chlorophyll levels in hostas, reducing stunted development and making their leaves greener and thicker. It also promotes bushier plant growth and increases disease and insect resistance.
Get Rid of Slugs
The most prevalent pests that attack hostas are slugs. Slugs can be deterred by placing a tablespoon of Epsom salt in the shape of a ring around hostas. Their bodies will be irritated by the sharp crystals of Epsom salt, and they will avoid getting near your plants. For optimal results, apply once a week.
For Yellowing Hosta Leaves
Magnesium insufficiency might be indicated by yellow hosta leaves. Once a month (or more frequently if necessary), sprinkle a spoonful of Epsom salt around the base of your hosta plant per 12 inches of height until it begins to look green again.
For Lush and Healthy Hosta Plants
Even if your soil is not magnesium deficient, factors such as acidic soil, low soil temperature, soil cation exchange capacity, high potassium, and salt can all impede Magnesium uptake by plant roots.
In that case, foliar feeding your hosta plants with Epsom salt solution is a good idea:
- During the rapid growth period, mix 2 teaspoons Epsom salt in 1 gallon of water and sprinkle on the foliage once a month.
- Reduce the amount to 1 tablespoon as growth slows. Your hostas will stay lush and healthy with the foliar treatment.
Mix Epsom Salt with Fertilizer
To improve the efficiency of the all-purpose liquid fertilizer, mix a pinch of Epsom salt with it before feeding the hosta plants, then apply according to the recommendations on the fertilizer’s packet.
Should hostas be cut back for winter?
Hostas are a perennial plant, which means they lose their leaves in the winter. This easy-to-care-for plant is known for its huge waxy leaves that produce long stalks with blossoms, although it will need to be pruned down in the fall. It is critical to prepare the hostas for winter in order to ensure strong blooms in the spring. Pests like slugs and bunnies can nibble the leaves and make them seem ragged as the weather becomes cooler. The leaves of the hostas also start to droop and die back. Trimming the hostas after the first hard freeze is beneficial.
Will hostas regrow if cut back?
Many hosta cultivars, for example, offer attractive fall color. During early fall cleanup, they are frequently trimmed back. I try to prune back day lilies in late summer or early fall, well before a killing frost, because they tend to appear ragged at that time. After being chopped back, they frequently sprout new growth.
Do hostas like water?
Small or medium plants will require a good soak once a week once they have established themselves. Hostas tolerate drought but need moist, well-drained soil. Increase the watering frequency to three times per week if the weather is warm. Large hostas should be watered twice a week in the summer and daily in the winter, especially if they get a lot of sun.
Growing Hostas in pots necessitates more frequent watering. Because pots drain faster than gardens, giving the plant the slow sip it requires can be difficult. Water the pot every three days during the summer months. If the soil still appears to be too dry, it may need to be watered on a daily basis.
