Choosing and Using Fertilizers in the Yard and Garden

Update: 2021-05-21


Plants need air, water and sunlight, but require sources of essential nutrients too. Fertile soil rich in organic matter provides nutrients to be sure, but fertilizer is typically needed to grow vigorous, healthy plants. Organic or not, slow release or fast acting, specialty products or versatile mainstays – we face a lot of options when choosing fertilizers. And that doesn’t even begin to cover when and how to use the fertilizer for the wide diversity of plants you’re growing. 


In this episode of Granite State Gardening, UNH Extension’s Emma Erler and Nate Bernitz are joined by Becky Sideman to share proven tips and solutions for using fertilizer to grow healthy and productive plants in the garden and landscape. The conversation brings up topics and questions bound to get gardeners of all experience levels thinking about fertilizing plants in the yard and garden in new ways.

UNH Cooperative Extension’s Vegetable & Fruit team, together with a group of undergraduate and graduate students at the University of New Hampshire, conduct research on vegetable and fruit crops. While the team does much of their work at theNH Agricultural Experiment Station in Durham, NH, they are located throughout NH and their research project topics are driven by the needs of NH growers. The team believes that using effective growing practices for our region (including new varieties, new crops, and season extension strategies) can help farmers diversify, improve yields, and improve crop quality. Many of their integrated research and extension projects focus on high-value specialty crop production systems and methods of extending the growing season (e.g. season extension). They offer an up-to-the-minute snapshot of what we're up to on Instagram at unh_sidemanlab.
