Maui Extension hosts Ag teachers

Ag teachers on Maui, Molokaʻi, and Lanaʻi haven’t been able to gather, share knowledge, and renew friendships for a while now. So along with Britney James of the Maui Economic Development Board’s STEMworks Program, in partnership with Maui County Farm Bureau, we decided to host a professional development. It was great to see Ag teachers from across Maui County come together for the event. We kicked off with a tour of HokuNui Maui’s Agroforestry program. The Hewahewa family shared the history of the farm and how they decide which plants to grow in their agroforest so teachers could implement the same choices in their classes.

HDFS + UGC Fruit Hui team up to collect, donate fruit baskets

For this past Thanksgiving, student interns Leah Ramos and Kalani Akau and their advisor, Sothy Eng, took the initiative to collect fruits from families' backyards and put them together in baskets, which they donated to Mental Health Kōkua, a local organization that serves adults striving for mental wellness. The Urban Garden Center’s Fruit Hui immediately came on board, generously donating its entire harvest of lemon, tangerine, orange, papaya, mango, and starfruit, estimated to be more than 100 pounds of fresh, nutritious, delicious items – and all hand-picked by UGC volunteers Linda, Susie, Glenn, Jessie, Karen, Kim, and others.

“These fruit baskets not only provide nutritional food for our community members, but also help toward promoting sustainable food systems as abundant foods are being sourced and shared with those who are struggling with food access,” says Sothy of the Human Development and Family Studies program in the Dept. of Family and Consumer Sciences. “This food distribution is one of the elements within the food systems that connects between the home/community food systems with our community members who are suffering from social injustice of healthy food access."

Extension’s Kalani Matsumura adds, “The UGC volunteers normally donate these fruits to the Hawaiʻi Food Bank, as well as the CTAHR student food pantry, but today they are happy to support HDFS students’ Thanksgiving project to put together nice baskets for the needy. Thank you for the great work you're doing for families in Hawaiʻi!

Mental Health Kōkua serves adult individuals with disabilities and chronic illnesses often causing the individual to feel alone and separated from reality, explains Les Gusman, County Director-Oahu.

“This random act of kindness that you are providing gives them hope,” he says. “We appreciate Brooke Fisher, an HDFS alumni and MHK former intern, who is now doing her Master's in Social Work at Columbia University, for her continuous effort connecting CTAHRʻs Home Garden Network program to our organization.”

Extension visits the Institute for Human Services’ aquaculture garden

Serving 359,159 meals to the homeless in a single year requires a literal ton(s) of ingredients. To supplement the meals with fresh, locally grown produce, the Institute for Human Services maintains a rooftop garden on top of its Dillingham Blvd. location, carefully tended to by GoFarm Hawaiʻi graduate Lubei Cavin. At her invite, eight agents from O’ahu County Extension had an opportunity to return to IHS’s rooftop garden to see how all the magic happens. Aquaponically grown lettuce, basil, kalo, and sweet potatoes were just some of the many commodities growing.

Lubei led an aquaculture production “class” for her visitors, and shared her focus on the humanity side of agriculture and how the garden provides food to keep people fed and nourished. Extension also had an opportunity to see how the veggies are processed in the kitchen, then packed and served to IHS guests across Oʻahu.

“The field trip was eye opening,” says Jari Sugano. “It reminded us how important it is to put food into the hands of those who need it the most.”

Following the visit, Extension and volunteers made a special effort to help IHS supplement its holiday spread. They harvested and donated mandarins and citrus from Extension agent Jensen Uyeda field trial at the Poamoho Research Station.

“As this holiday season approaches, please be mindful of those in need and support organizations like IHS who strive to end homelessness in Hawaiʻi,” says Jari. “In 2020, IHS housed 2,619 clients and sheltered 2,145 people – besides serving all those meals. So please consider making donations of food, clothing, home goods, toiletries, monetary gifts, gift cards, etc.”

Extension is featured on AARP’s “Locally Grown” series

Extension’s Amjad Ahmad basked in the virtual limelight as the featured speaker in “Locally Grown,” a video series by the American Association of Retired Persons, Hawaiʻi chapter, and Windward Community College. Each week during the cooking webinar series, which ran for six weeks, Amjad gave a presentation and answered questions about growing conditions, the best time to harvest, the best season and environment to grow the crops during, and other related questions. The virtual events also covered cooking demonstrations of locally grown crop (sweet potato, breadfruit, papaya, taro, lemongrass, and kabocha pumpkin) lead by a chef from Windward’s culinary program.

In all, the webinars engaged 1,329 people over the six-week period.

“Amjad did a great job representing CTAHR at the request of AARP!” says Jari Sugano. “His talks helped to heighten awareness of locally grown foods that are easy to grow – and nutritious.”

The Care and Feeding of Your Lawn

Turfgrass expert explains how to keep your lawn green and happy

The Care and Feeding of Your Lawn

“I fought the lawn, and the lawn won…” If that’s your theme song, it doesn’t have to be. By sticking to a few simple principles, you can create, maintain, and manage a beautiful green lawn on your property.

Turfgrass Selection. Make sure to select turfgrass species or cultivars suitable for your growing conditions and expected use. Here are the most common species in Hawai’i, and their best selling points:

  • Bermudagrass does very well in the heat
  • Zoysiagrass is relatively low maintenance
  • St. Augustine grass has the best shade tolerance
  • Seashore paspalum can handle very high water or soil salinity.

If you don’t mind some variation in color or texture, you can try using a turf blend or turf mix, combinations of two or more cultivars of the same species or even two or more species, to get the best of both worlds.

Establishment. The best time to make major preparations and modifications to the soil is before you establish your lawn. Now’s when you can incorporate amendments like fertilizer and other nutrients, based on soil test recommendations, to provide the best possible growing conditions.

There are four main ways to establish a home lawn in Hawai‘i:

  • Growing from seed is the least costly, and it offers a variety of seed options. However, it takes the longest time, and you may run into the most weed issues during establishment.
  • Sod is fully grown turfgrass you can buy from sod farms—it unrolls over the ground like a carpet. This method is the most expensive, and selection is limited to the varieties that are locally available. On the plus side, sod offers instant lawn coverage and almost no weed issues during establishment.

The other two methods are compromises:

  • Plugs and sprigs are small pieces of turfgrass sod installed in the soil that grow together for eventual coverage. Plugs require consistent spacing between them; sprigs don’t need to be installed in any particular pattern. These methods work because all warm-season turfgrasses used in Hawai‘i spread horizontally by rhizomes (below-ground runners) and/or stolons (above-ground runners). Both cost less than sod and take less time than establishing a lawn from seed.

Weed control is essential during lawn establishment, especially when seeds, plugs, or sprigs are used.

Caring for Your Lawn. You can maintain high-quality turfgrass and minimize pest problems with appropriate mowing, irrigation, fertilization, and other cultural practices.

  • Mowing: If possible, follow recommendations for mowing height and frequency for your turfgrass. Usually the higher the mowing height, the more robust the root system and the better the overall health of the grass.
  • Irrigation: Too much or too little water can leave turfgrass vulnerable to pest problems. Deep and infrequent irrigation is usually better, while shallow and frequent watering promotes shallow rooting. If possible, water in the early morning rather than the late afternoon or early evening.
  • Fertilize your turfgrass as necessary, but avoid excessive nitrogen, which could stimulate some fungal diseases or result in weak grass blades that are susceptible to insect attack. When feasible, consider organic fertilizers, as they are typically slow release and could support soil microorganisms and improve soil food web health.
  • Thatch should be managed when feasible, and clippings can usually be left onsite.

Pest management. Insects, weeds, fungal diseases, and plant-parasitic nematodes are some of the most common turfgrass pests. Some common insect pests in Hawai‘i include the webworm, armyworm, cutworm, and fiery skipper caterpillars; frit fly; rover ant; mealybug; and bill bug. Common turf weeds are broadleaf weeds, grassy weeds, and sedges. Some common fungal diseases include dollar spot, rust, take-all patch, and fairy ring.

Try an integrated pest management approach, which includes deciding on an acceptable pest threshold, monitoring and early detection, and effective treatments to control target pests. If possible, try to manage lawn pests through a system approach: try cultural, mechanical, and biological control approaches before resorting to chemical pesticides. When using biological control products or chemical pesticides, always read and follow labels strictly. If you’re not sure about your lawn problems, ask a turfgrass expert or your local UH Extension service before taking any major actions.

Now, sit back and enjoy your lawn with a picnic or a game of bocce ball!
