(A friendly caveat – this post does not lend itself well to images. So the pictures here are simply eye candy from my 2019 trip to London to reward you for considering this visually drab but important topic.)
I’ve been involved in Extension education for 17 years and one of the most important things I’ve learned is that Extension audiences want information that’s easily understood and has obvious practical use.… Continue reading this article “Not all Extension publications are created equal”
If you do any searching for gardening (or even think about the color green), you’re likely bombarded with adds on social media and search engines about all stuff gardening. One of the recent trends is microgreen production. There’s all kinds of fancy little systems and gizmos that will help you grow microgreens for a price. But what are microgreens? Are they the same thing as sprouts? And do they have the same food safety issues as sprouts? … Continue reading this article “Tiny plants that pack a flavor and nutrition punch: getting in on the microgreen trend”
When my turn comes up to blog for the Garden Professor site I like to reflect on the horticulture in my own gardens and orchard. Right now I am focused on pruning my old apple and stone fruit orchard. It has suffered bear attacks, drought, and mismanagement before we arrived in 2018. The previous owners were very aware of the need to treat pruning cuts large and small. The remnants of tree wound dressings are found all through our orchard and range from white latex paint to silicone caulk.… Continue reading this article “Pruning Paints Debunked”
This is the last part of our discussion on gardening in soils that contain heavy metals (you can catch up on part 1 and part 2 if you need to). Today we’ll focus on the strategies you can use in your gardens and landscapes to reduce your exposure to soil-borne heavy metals.
Test your soil!
First – and this should really go without saying – you must test your soil to determine if it contains heavy metals of concern.… Continue reading this article “The complicated issue of heavy metals in residential soils. Part 3: How can we garden safely in the presence of heavy metals?”
Looking back to January 2020, most of us would have never imagined the year we’ve had. All of our best laid plans went away and instead we socially distanced, scavenged for toilet paper, and canceled events and vacations. But one thing that wasn’t canceled was gardening. By June, garden retail sales had increased 8.79% over the average, a big jump for a trend that was already showing increased gardening over the last few years. Wanting to grow food to ensure a safe food supply was one reason gardening increased this year, but it also served as away for people break the boredom of being stuck at home. … Continue reading this article “Planning Ahead (in a pandemic) for Vegetable Garden Success”
Last month we discussed the various heavy metals that might end up in your garden and landscape soils. Today we’ll consider how different factors can alter heavy metal uptake by plants.
First of all, let’s consider plant uptake. Plant roots can either accumulate a particular metal or exclude it. If they exclude it, that’s the end of the story, (though it’s still a soil contaminant).… Continue reading this article “The complicated issue of heavy metals in residential soils, part 2: How plant species and environmental variables complicate the issue”
Our first major frost hit my part of Arizona a month ago, killing all tomato vines. I did my thanksgiving cleanup chores–removed all the vines and ground them into mulch. I noticed an ominous symptom on one a few of the heirloom varieties (Prudence Purple) that I removed—galled roots. This symptom when seen on tomato is evidence of Root Knot Nematode (RKN). More about RKN shortly. Nematodes are non-segmented worms, mostly free living in soil and feed on bacteria, fungi, small animals or each other.… Continue reading this article “The worms crawl in and the worms crawl out but these worms kill your plants”
Systems to grow fresh produce in your home using hydroponics or other automatic processes have been popular for several years but seem to be even more popular this year with more folks home and looking for something to do and hoping to produce their own food. As a result, these systems are popping up on holiday wish lists and gift buying guides all over the internet. But are they worth it? And if so, what should you look for in a system? … Continue reading this article “Hydroponics for the Holidays? Home Systems are a hot holiday gift list item”
So many of us are growing our own vegetables – either as experienced home gardeners or as COVID19-isolated novices. There is a lot of effort in figuring out garden beds, vegetable choices, and growing medium – but one of the issues rarely considered is whether there are heavy metals present in the local soil and/or growing medium. We can’t see heavy metals, or smell them, so we need to have a way of assessing their presence before we plant edibles.… Continue reading this article “The complicated issue of heavy metals in residential soils, part 1: What are toxic heavy metals, and where do they come from?”
Summer is done. The last apples are coming off my orchard trees now and persimmons are ripening fast. Some fruit remains to be picked but most is off. As garden productivity subsides we turn our tasks to winter. In Southern California it means planting the winter vegetable garden, in Northern Mn snow has already flown so gardens are shut down now. For fungi that may be pathogens in our gardens, it is a time for reproduction.… Continue reading this article “Fall is for fungal fruit”
