Here are some questions I fielded this previous week at the Springs Preserve.
Concern: Is it real that Thanksgiving feedings of my cool-season lawn keep it greener through the winter and improve its overall health next season?
Answer: Yes. It keeps the yard greener and stronger even into next summer. Also, aerate your lawn now. The aerator removes plugs from the soil so water penetrates much deeper triggering deeper rooting. To avoid icing during the winter season, water during the midmorning hours. If freezing temperature levels are anticipated, turn off your watering system.
Q: Does overseeding my Tifway Bermuda lawn injured it next summer season?
A: Skipping the process leads to a more vigorous yard because Bermuda is able to save nutrients in its stolons and rhizomes for next summertime. It likewise gets rid of taking on ryegrass as the Bermuda comes out of dormancy next spring. Likewise, inactive grass allows you to find spray winter season weeds without damaging the lawn.
Q: Is it real that fertilizing warm-season Bermuda with iron keeps it greener longer into the fall?
A: Yes. But it’s far too late to do it now. Making three applications of iron 2 weeks apart in mid-September will keep your lawn greener. With Bermuda, late-fall nitrogen feedings harm the turf’ ability to save nutrients. This emerges with bad green-up next spring.
Q: Why won’t the leaves on my eight years nandina turn red in the fall? It gets filtered early morning sun on our patio.
A: It’s not getting enough direct sunlight. Move it to a brighter place. I planted a Hacienda climber on the north side of my home without considering sunshine, and it’s never developed its standard autumn colors.
Q: When do we plant bulbs?
A: The faster the much better. Bulbs need winter, and we don’t get much. Enhance the soil with bone meal to make the flowers prettier. If drain is a problem, plant somewhere else.
Q: Why are the older leaves on my houseplants dropping?
A: The shortened days and cooler nights cause summer season leaves to drop. Your first response might be to feed, but do not do that. Turn plants weekly a quarter-turn so that leaves get equal quantities of sunlight for balanced growth.
Q: Can we decrease the height of a tree without harming it?
A: Yes. Recognize a branch you need to get rid of. Cut the branch off where it connects to the limb, taking care never ever to leave a stub extending from the remaining branch. Continue throughout the tree till you have actually reduced its height.
Do your pruning after leaves drop so you’ll make smarter choices.
Secure the now-exposed limbs from the sun due to the fact that borers invade sunburn-damaged trunks and limbs. Paint limbs with a white latex paint to avoid the burning and deter the borers.
Q: How do I prune my 3-year-old Chinese elm?
A: The best time to prune is after the leaves drop. The cardinal rule is never ever getting rid of more than 25 percent of living tissue (branches, stems, leaves) in any one year otherwise you’ll badly stress the tree. You desire more leaves next spring to manufacture more food for your tree.
Start pruning by eliminating any damaged, dead or crossing branches. This might be all that is needed for the year. For a young tree, leave numerous branches on the tree but make certain they’re not spaced too close together.
Herbs are marvelous plants. They’re easy to grow, versatile and yummy. Discover how to grow them in a workshop at 8:30 a.m. every Saturday and Sunday through November at the Springs Preserve, at 333. S. Valley View Blvd. I teach the Saturday class.
The University of Nevada Cooperative Extension has a new demonstration garden to display. Master gardeners will show how to “Paint Your Garden with Color” utilizing desert-adapted plants at 9 a.m. Saturday at 8050 Paradise Roadway.
The demonstration garden has more than 500 types of trees, shrubs, perennials, palms, cactuses and agaves. The premises are open for self-guided walk-abouts on weekdays.
Likewise at the Cooperative Extension, horticulturist Bob Morris will resolve soil issues and explain typical garden bugs and the best ways to control them organically at 6 p.m. Thursday.
The garden tour and pest workshop are both complimentary. For more information, call 257-5555 or email [email protected]
