Solutions For Environmental Stressors

As we all adjust to our changing climate, we are forced accept that “unprecedented” weather events are now the new normal. This leaves growers of all types scrambling to figure out what’s best for their plants in this new landscape. Luckily, there are some smart people out there creating effective and innovative solutions to the most common environmental stressors that plants face. These products approach issues like heat, drought, cold and salinity in a variety of ways, but they are almost universally meant to be used proactively. So, while it may be too late to save some plants for damage that has already occurred, it’s never to late to plan for your next planting. 

Heat & Drought 

I thought about separating this into “Heat” and “Drought”, but products that are good for one are good for the other. These are two-for-ones, if you will.

One of our newest products this year is Mikro H2O. This innovative powdered product introduces two species of Rhizobacteria (Bacillus amyloliquefaciens and Bacillus subtilis) into the soil. They will then secrete natural polymers around the root zone and build biofilm. This biofilm forms a protective shield that holds water and protects the roots from evaporation and other stressors while improving nutrient uptake and essential functions. All this and it’s remarkably cost efficient. 

Another product that works in the root zone is NutriRoot®. This liquid combines a gentle 2-2-3 fertilizer with a blend of seaweed extract, nutrients, humic acid, humectants and surfactants. This combination provides nutrition and encourages root development; but, through its humectants, it enables the soil to literally pluck water from the humidity in the air and deliver it to the root zone.  This allows for less watering while still maintaining a steady and secure water supply. Hydretain® (which comes in 3 versions) uses the same water management technology as NutriRoot and performs in the same way. This main difference is that Hydretain does not contain the fertilizer. Hydretain’s claim to fame is that it can reduce waterings up to 50%.

We also carry a number of products with water-soluble polymers that hold water and then slowly release it to the plants as needed. In addition to being water-conserving devices, these polymers can condition the soil and improve penetration of water into the soil. Soil Moist™ Water Aide™ is an organic OMRI-listed version with many application possibilities. Another option we have is pH-neutral WaterWorks Crystals®. It is as versatile and effective as the Soil Moist option and can reduce waterings up to 75%. The last option I want to mention here is Plant Keeper. This polymer-based product was developed for use when you need a watering to last extra-long – it will keep the plant good for up to two weeks. This is perfect for when you have travel plans, or it would be great for use with a Christmas tree.   

Salinity 

A home by the sea is enviable in many ways, but it can be challenging to grow in soil with a high salt content. In truth, you don’t even have to be right by the sea – hurricanes and other storms that brew over the ocean can dump great quantities of salt water many miles inland. While this is not a condition that can be resolved quickly, it is also not hopeless. You just need to commit to the process and be conscientious in treating your soil.

Yucca schidigera is the smart go-to for natural desalination. Yucca extracts reduce salt buildup by reducing dry pocket formation within the soil and increasing permeability of the soil. You can access this valuable commodity in a liquid form  by using Therm X-70® or SaferGro® Natural Wet®. Both of these are very affordable and have multiple benefits beyond desalination. If you prefer a dry product, RAW Yucca Flow is an excellent option. It’s fully water soluble and a little goes a very long way.

     Water

Too much water is as devastating as too little and, in many ways, it’s harder to come back from. Floodwaters don’t just drown plants outright; they can carry contaminants and pathogens looking for a place to call home. Before you can rebuild your garden, you’ll need to let things dry out and then re-build your soil (more on recovering from too much water in my blog here). When it comes to building soil, we have a great deal to choose from. The following are a few I have chosen to give you an idea of what to consider:

TerraGrow – This OMRI-listed powder is chock-full of seven beneficial microbes as well as important nutrients. TerraGrow can bring nearly any soil back into winning condition. The large size (10 lbs and up) of this product may not work for smaller home growers, but perhaps you can use it as an example of what kind of product to get. We have other similar options that will work for you (look in Soil Amendments, Micronutrients & Biostimulants). 

BioAct™ SD – Powered by beneficial microorganisms and humic acid, this organic soluble powder chews through organic matter while supplementing the microbial life. If you have some gnarly fields (or a garden) full of stubble and crop residue after high water, this could be the starting point you need. You will, of course, need to let it all dry out first. 

Unleash™ - This liquid inoculant is made with a proprietary blend of both aerobic and anaerobic rhizobacteria to offer multiple plant benefits. These bacteria would work well in a flood-ravaged setting.  It was developed for cannabis and hemp cultivation, but it can be used broadly in agriculture. This is not an inexpensive product, but it’s cost per application isn’t bad and the sheer expanse of its uses and benefits make it worth the cost.  

VRD™: Volcanic Rock Dust™ - We are really getting back to basics with this item. VRD (or any soil amendments sourced from volcanic rock) are rich in trace and essential minerals that are crucial for healthy soil. This particular amendment has Calcium, Magnesium, Iron, Sodium, and hydrophobic Fulvic Acid (which boosts nutrient acquisition in the soil). Soils treated with VRD receive the minerals in a slow release for long-term, continuous benefits. Volcanoes started the whole soil thing, so rebuilding using volcanic amendments just makes sense. 

There is a lot to worry about weather-wise these days, but your garden does not need to be one of those worries. We’ve got you covered in one way or another. 

Take Care.

Man, It’s Stupid Hot Out There!

No matter where you stand in the climate change conversation, it is undeniably HOT out there these days – outrageously, hellishly, suffocatingly hot! 200 million Americans are currently experiencing record-breaking heat, with many places expected to reach temperatures higher than those we’ll have here in Arizona. And don’t give me the “it’s a dry heat” refrain, an oven is also a dry heat. I have lived in places with high humidity and know how debilitating it can be and most of the places dealing with this heat wave will also have that humidity. The combination of heat and humidity is just plain miserable.

Never touch metal that's been in direct sunlight.

We Arizonans take pride in our ability to muddle through our summers. Most of us accept the heat as payment for having such mild winters. There are many strategies to get through, but when asked how one copes, my favorite response is “Live like a desert creature”. Simply put, avoid the sun at all costs, don’t over exert yourself and drink plenty of water. Seeking shade is a competitive sport around here in the hottest months; I’ve seen groups of people clumped together under the thin strip of shade a telephone pole offers.Even local reptiles know this game. Having said all that, many (probably most) Arizonans, myself included, are lucky enough to travel from air-conditioned homes in our air-conditioned cars to other air-conditioned locations. But, getting to that car in the parking lot and getting it cooled down can be pretty gnarly!

 

"Facekinis" in China - not creepy at all. 

People can wear lighter clothing (or add questionable sun protection like the image on the left) and adjust their routines in answer to excessive heat, but what is a  plant to do? The higher the temperatures, the more need for water; finding ways to stretch your water is key. In Arizona, Xeriscaping has long been a widely appreciated model for growing. With its emphasis   on water conservation, mulching and using heat   tolerant plants, it is an ideal solution for areas like   ours that experience heat and drought.The elimination or reduction of turf is also a key factor in Xeriscapes. Many people around the country still love their lawns, but in cities like ours where water is at a premium they have become less socially acceptable. I encourage every reader to reconsider their lawn and either eliminate or reduce them; it is a small but important way to serve the environment.

Backyard Xeriscape, Tucson, AZ

Adopting a Xeriscape approach to landscapes and gardening takes some planning ahead. This works well in Arizona because we always know it will be hot and dry. With current climate conditions being what they are, excessive heat and/or drought is a reality now for non-desert parts of our nation and, if you want to grow something, planning ahead is for everyone. Here are some ways you can build a heat tolerant green space; some take planning, but others offer heat help right away:

Soil Amendments – Building a soil that holds and properly distributes water and water-borne nutrients to plants is a solid foundation that gives plants the tools to fight the heat. You can chose something like Earthshine, a soil enhancer mix that contains biochar and other beneficial additives. Or a powder like Harvest Gold Organics Premium Soil Conditioner, which contains silica and micronutrients. Or even a single ingredient additive like the Elemite, also known as ARBICO Organics™ Soil Replenish™. Another (very affordable!) option is ARBICO Organics™ Rice Hulls. The bottom line is that any type of high quality soil amendment will bring you healthier soil, which means healthier plants that can better handle heat and drought stressors.

Composting & Mulching – You can increase your soil’s water holding capacity by up to 7 times by simply adding compost. You can use ready-to-go compost or begin making your own; we have options for you here. Mulch, mulch, mulch – in any form, by any name, just do it! Mulching options are many: coco coir like Prococo Coconut Coir, and other cover crops and biodegradable weed block paper, which provides weed control as well as mulch. Another interesting option is Slug Gone. This sustainable slug (and snail) control product is made from wool and is placed in and around garden beds. It will swell from the moisture and make a scratchy mat that slugs will refuse to cross. In performing its slug control duty, it also retains moisture and reduces water usage.

Yucca in its native environment

Adjuvants – Another way to protect plants from heat stressors is to add adjuvants to their water. Yucca (Yucca schidigera) is a desert native and knows all the tricks to survive in such a harsh environment. Adjuvants like RAW Yucca Flow and Therm X-70 that use extracts from these plants deliver the secrets of the Yucca plant to your backyard. You can give your plants immediate heat relief by adding these adjuvants right away.

Covers – Use covers to protect your plants from the pounding sun. Here are many versions to choose from, or create your own. Here is a video to show you how.

Containers – Consider moving plants from beds to containers. Container planting makes water conservation easier and gives you the ability to move plants in and out of the sun.


Embrace heat-loving plants – Seek out and cultivate plants that are well adapted to hot weather. Here are some great heat-friendly plants that you are probably familiar with:
Sunflowers – with a name like that…
Amaranth - pretty – and you can eat it!
Echinacea – beloved by pollinators – 
Yarrow - native to temperate North America

Yarrow blooms

Unless you live in the far northern regions of our country, you may be surprised to find there are native summer species waiting to be loved. Here in the Tucson, we have a fabulous source for desert-adapted native and heirloom plants thanks to Native Seeds/SEARCH. They have a remarkable variety of interesting seeds and stories that go with them.

Stay cool out there.
