2021 Rose & Grapevine Pruning

General Landscape and Garden    Treasure Valley

Posted on: April 2, 2021 by Nic Usabel

It’s time to prune roses and grapevines in the Treasure Valley. The cold temperatures are milder, and the forsythia is in full bloom.

ROSES:
For a guide to pruning roses click the first link below. For a video tutorial click the second link below.

GRAPEVINES:
The University of Idaho Research & Extension Center in Parma recommends pruning grapevines in the Treasure Valley no sooner than mid-March to ensure that low temperatures do not kill buds after pruning. Grapevines can “bleed”, movement of sap from the cut, heavily when pruned in spring. This does not harm the vines. For a pruning guide on grapevines click the third link below. For a video tutorial click the fourth link below.

Additional sources not provided in the links below include Grapevine Management from Utah State University at https://digitalcommons.usu.edu/cgi/viewcontent.cgi?article=2672&context=extension_curall and Pruning Roses from Colorado State University at https://planttalk.colostate.edu/topics/trees-shrubs-vines/1763-pruning-roses/.

For additional questions on rose or grapevine pruning reach out to a local University of Idaho Extension office. Find your county office by visiting https://www.extension.uidaho.edu/find.aspx.

2021 Spring Lawn Fertilization & Care

General Landscape and Garden    Treasure Valley

Posted on: March 15, 2021 by Nic Usabel

Spring lawn fertilization for cool season grasses recommend that fertilization be made while energy is being directed to root growth, which follows with leaf growth. This timeframe for cool season turf in the Treasure Valley traditionally March thru early May. If mulching is a practice in your lawn maintenance plan, nitrogen can be reduced by ½ pound annually. Attend a “Lawn Care for Success” class to learn more about maintenance, fertilization, and watering. Click the link https://bit.ly/21Lawn2C to register for the class.

The proper rate of fertilizer application is best achieved when using a soil test result to identify the fertilizer needs of the soil. Use the second link below to access a publication to help calculate rate of fertilizer application for the lawn. Applications should be split between spring and fall. Application rates should not exceed 1 pound of nitrogen per 1,000 square feet in any one application, access the third link below to review the publication to identify additional time(s) for application if rate would exceed the 1 pound of nitrogen per 1,000 square feet limit with only and spring and fall application. Always follow label directions.

For more information on how to obtain a soil sample to a soil test submission contact your local University of Idaho Extension office. Contact information can be found at https://www.extension.uidaho.edu/find.aspx

Another method of identifying application rate is based on the level of turf maintenance from low to high traffic. Application rates should not exceed 1 pound of nitrogen per 1,000 square feet in any fertilizer application and always follow label directions. Review descriptions, timing, and rate of application below.

1. Light use is classified as occasional foot traffic or little to no play from children. Annual turfgrass recommendation is 0-1 pound of nitrogen per 1,000 square feet. Split the application between a spring and fall application.

2. Moderate Use: Typical children’s play and occasional garden parties. Annual turfgrass recommendation is 2-3 pounds of nitrogen per 1,000 square feet. Split the application equally between a spring, early fall (late September) and late fall (Mid October to Late November)

3. Heavy Use: Frequently used sports field play, heavy traffic and/or frequent garden parties. Annual turfgrass recommendation is 4-6 pounds of nitrogen per 1,000 square feet. Apply 1 pound of nitrogen per 1,000 square feet in spring, 0.5 pound of nitrogen per 1,000 square feet late May/early June, 0.5 pound of nitrogen per 1,000 square feet late June/early July, 1 pound of nitrogen per 1,000 square feet early fall (late September) and 1 pound of nitrogen per 1,000 square feet late fall (Mid October to Late November).

If your lawn is suffering from soil compaction or development of a thick thatch layer core aeration can be completed in the spring but is preferred in fall while weed pressure will be reduced. For more information on core aeration reference the fourth publication link below.

Spring provides the opportunity to seed new turfgrass areas or to over-seed areas that may have been damaged over the winter. Cool temperatures will promote germination and growth of cool season turf species, tall and fine fescues, perennial ryegrass, and Kentucky bluegrass. Weed pressure can be higher this time of year so consider your weed control options or consider overseeding in the fall. Select pest resistant or recommended turfgrass cultivars when possible.

If there are additional questions on lawn care or weed management reach out to a local University of Idaho Extension office.

Educational Video-Monitor Flying Insects to Improve Management

All Crops    All Locations

Posted on: March 3, 2021 by Jason Thomas

Do you know what types of insects are entering your field and garden at different times of the year? Would you like more information to help you decide when to implement pest control actions? The University of Idaho Extension just recently released this 5 minute video to demonstrate a way to monitor for flying insects entering your crop or garden. Click the link below to watch.

https://youtu.be/9C-V09gDfY8

Monitoring insects entering your field/garden can help you know when to take specific control actions. For example, in seed potato production it is a critical practice to help us monitor when aphids potentially harboring viruses enter a field. The traps do most of the work for you. You just have to check it every so often and maintain it over the growing season. Utilizing traps can be a helpful way to implement integrated pest management into your operation.

For other insect trapping/monitoring ideas the following demonstrational videos may be helpful:

Chlorpyrifos Survey

All Crops    All Locations

Posted on: February 21, 2021 by Stuart Reitz

Please help us gather valuable information about chlorpyrifos (Lorsban and related insecticide products).

Restrictions on the use of chlorpyrifos and the complete revocation of its registration are under way. Our team has initiated a cross-commodity collaborative research project to identify viable options as alternatives to chlorpyrifos. Research will be conducted at several locations in Oregon to determine the efficacy of currently registered chemistries and newer products in onion, corn, cherries, grass seed, and clover seed. This survey will provide critical information on the use of chlorpyrifos across all crops and will help us identify issues to improve our research project.
https://oregonstate.qualtrics.com/jfe/form/SV_28ZDP4ZJ282CcES
Survey participants are eligible for a $25 gift card.

If you have questions or comments about the project, please contact Silvia Rondon, Project Leader, OSU Hermiston Agricultural Research and Extension Center, 541-567-8321, silvia.rondon@oregonstate.edu.

Research and Outreach Programming for Pulse Crops

All Crops    All Locations

Posted on: February 9, 2021 by Jerry Neufeld

Montana State University needs your help to improve our research and outreach programing for pulse crops. We’ve created a survey to help us collect information that will directly impact what we research, how we develop our future programming, and also increase our ability to apply for pulse crop research funding.

The survey should take about 10 minutes to complete. You can use your phone, computer, or tablet.

Your responses are completely anonymous – we have no way of connecting people to answers. Also, the data we collect are always aggregated (all answers summarized together), so that individual responses are never seen by anyone but the researchers.

Here’s a link to the survey: https://bit.ly/Pulses2021; you can copy it into your browser.

If you have any questions about the survey or our research, please don’t hesitate to contact Mary Burrows at mburrows@montana.edu or my research associate at monica.brelsford@montana.edu or by phone at (406) 994-5155.

Thank you for helping out research and Extension!

2021 Peach Leaf Curl Delayed-Dormant Spring Application

General Landscape and Garden    Treasure Valley

Peach leaf curl (Taphrina deformans)

Posted on: February 6, 2021 by Nic Usabel

If you experienced peach leaf curl on peach or nectarine trees during the 2020 growing season and did not treat in the fall a delayed-dormant application before floral buds open is recommended to help with control.

DESCRIPTION: Peach leaf curl caused by fungus Taphrina deformans and is specific to peaches and nectarines. Trees that are infected will have leaves that are distorted or curl, appear blistered, and develop a yellow or red color.

CONTROL: Spray with an approved fungicide such as lime sulfur or copper-based fungicide. More chemical options listed by viewing the PNW handbook link below. Apply according to label directions and instructions. Cultural control for backyard growers includes removal of infected leaves that have fallen and selecting resistant cultivars.

If you have additional questions, contact your local University of Idaho Extension office at https://www.extension.uidaho.edu/find.aspx.

2021 Pruning Deciduous Trees & Shrubs

General Landscape and Garden    Treasure Valley

Posted on: January 30, 2021 by Nic Usabel

It is time to prune deciduous trees (landscape & fruit) and shrubs. As a general guide remove no more than one-third of the tree when pruning. Reference the first and third link for pruning deciduous trees and for a video reference the fourth link. Reference the second link for fruit trees.

Prune shrub species which grow on the current season’s growth during the dormant period, usually late winter early spring. A few examples of flowering shrubs in this grouping including butterfly bush, heather, heavenly bamboo, hydrangea, shrubby roses and rose of sharon. Reference the third link for more information.

For shrub species which form buds on last season’s growth prune these species within about two months after the flowers fade. On these species, flower buds form in late summer and early fall. Winter pruning decreases the number of flowers the following spring as branches containing flower buds are removed. A few examples of flowering shrubs in this grouping include azaleas, lilac, magnolia, mockorange, serviceberry, and witchhazel. Reference the third link for more information.

For most areas of Idaho, plants that bloom before June 1 formed the flowers the previous year on old wood. Those that bloom after June 1 form flowers on new growth. Keep in mind that this is only a rough guideline.

For classes on pruning in the Treasure Valley see the attached file.
