Can I grow asparagus from seed? I saved the little red berries from my plants.
You can grow asparagus from seed. I have done so many times, but it takes three or more years for a crop, and growing from seed usually gives inferior plants. Better crops come from hybrid plants.
If the red berries from the female plant have dried over winter, there should be two or three black seeds inside. Clean them off and prepare your seed bed for planting.
Asparagus needs full sun and a sandy loam soil raked smooth. After the danger of frost is past, bury the seeds at a depth two times its diameter and keep the bed moist. In the third year you can lightly cut the pencil-thin stalks. There are often volunteers of female plants between rows you that can transplant. However, it is best to start asparagus by buying roots so you have a small crop the first year. Most varieties sold are male.
I want to raise the level of my lawn as much as 2 feet in places. I now have a large quantity of somewhat composted wood chips and I am wondering if I can use them as fill to raise the ground level and provide a good soil in which to sow a lawn.
“It is not a good idea to use only wood chips to raise the grade of an area,” says Greg Stack, University of Illinois extension educator, horticulture. While wood chips may raise the grade for a while, over time they will decompose and eventually the site will sink. Even using them as fill and putting soil over them is not a good idea.
“I would not use straight compost by itself to raise the lawn level, but mix it with soil,” adds Stack.
I have two 3-year-old rose of Sharon plants, about 20 feet apart. One blooms every year. The other plant forms about 100 buds and looks healthy, but it has not bloomed in the last two years. The buds are solidly closed and look as if they are rotting from the inside out. There does not seem to be any sign of insects on the plant. What is this problem?
From the description it sounds like your plant is infected with botrytis blight, a fungus disease that attacks buds before they open, according to Jim Schuster, extension educator, horticulture, University of Illinois. Your plant needs to be treated with a fungicide early in the season. Remove all diseased portions of the plant and any residue on the ground, as the fungus lives over winter in discarded material.
What are the three best houseplants that everyone should own and why?

I tell people to go sit in Woodfield Mall and look at what’s doing well. We like to sell what will grow, what’s easy. So there’s ZZ plant (Zamioculcas zamifolia). It will survive if you go away for a 2-3 week vacation. Needs little water. Chinese evergreen (Aglaonema) is a wonderful plant. Will grow in any light; also doesn’t take much water. And pothos (Epipremnum aureum). We like to keep it simple.

Mother-in-law’s tongue (Sansevieria trifasciata) is one of the easiest plants to maintain. Find a place with dim light or low sun and forget it. The plant just needs a drink of water every 2-3 weeks.
Peace lily (Spathyphyllum). This is a phenomenal plant.Very easy to maintain. Will thrive in filtered sun but will do equally well in dim light. This plant loves moist soil.
Spider plant (Chlorophytum comosum) is a plant that keeps on giving. Very easy to take care of, it will often send out feelers with a baby spider plant attached. Just pop the baby in a pot of soil, allow roots to form and cut it free from the mother plant.

People think orchids are difficult to grow because they look exotic, but the Phalaenopsis orchid is easy to grow. The blooms are elegant and can last up to three months.
Spider plants (Chlorophytum comosum) adapt well to most places in your home and are one of the easiest plants there are. They are forgiving if neglected, and they also improve the air quality in your home.
FIddleleaf fig (Ficus lyrata) is a trendy plant. It’s easy to grow and adds character to a room. It can get tall but that’s what makes it blend in nicely with your décor.

For high-light situations I like variegated Swedish ivy (Plectranthus madagascariensis). This trailing vine is so much fun with its vibrant white margin and aromatic scent. It prefers moist well-drained soil.
For medium light, I suggest mistletoe cactus (Rhipsalis pilocarpa). This is a cool trailing non-toxic succulent type plant that never likes to dry out. It is also not very sharp to the touch like other cacti. It prefer moist, well-drained soil.
For low light, I recommend snake plant (Sansevieria trifasciata). It’s very easy to care for as long as you let it slightly dry out between waterings. It’s very striking with its color and stiff upright habit.
I have a hoya houseplant that has been growing happily for eight years. It had flowers when I received it, but it hasn’t bloomed since. What am I doing wrong? Can I get it to flower?
There are many varieties of hoyas. In general, they are easily grown houseplants. Some are fragrant and some have a cascading habit. Give hoyas a moderate amount of light but not deep shade. They can remain in the same container for years without repotting.
Shortened day length, combined with cooler night-time temperatures and dryness over a couple of winter months should bring your hoya into bloom. “Let your plant go dry. It needs a bit of drought,” says Susan Izenstark, horticulturist at Jamaican Gardens, Morton Grove. “The bud is a nodule on the stem. Notice when it swells a little. This is your signal to begin watering.”
What is the largest tree that one can plant? We are trying to replace some 7- to 8-foot trees that were recently destroyed.
The foliage on our cucumber plants is starting to wither and turn yellow. They get plenty of water and I feed them regularly. What could be wrong?
I’d like to block an unattractive view of my neighbor’s house/yard. What are some good plant/tree choices to hide unattractive views?
