Humus Does not Exist – Says New Study

As a gardener we all talk about humus. Some of us even buy humus soil, and humic substances like humic acid and fulvic acid. We add compost to gardens to increase the humus level in our soils in the belief that humus is good for soil. Good garden soil is dark because of the high humus content.

If there is one thing all gardeners agree on, it is that humus is good for the garden – right?

Maybe not!

Science now says our beliefs about humus may be wrong. In this blog I will review some earth shattering news – or is that soil shattering news?

Mosquito Repellents That Work Against Zika Virus

Many people are against synthetic chemicals and will not consider products like DEET. As I have reported before in DEET- is It Safe?, DEET is quite safe but many still do not believe the facts.

In the last couple of weeks the Zika virus has been all over the news. The World Health Organization has declared Zika virus a ‘public health emergency’ of international concern.

Which mosquito repellents work best against Zika? Are any of the organic products recommended? It is time to have another look at the mosquito problem.

Styrofoam Cones – Do They Keep Roses Warm in Winter?

As winter approaches, we worry about our poor plants making it through the cold. All manor of wrapping devices are used to protect them and Styrofoam cones, also called rose cones, have become popular in recent years. Do these contraptions work? If they do, how much warmer do they keep your plants?

There is a lot of talk on the internet about Styrofoam cones. Many extension offices recommend them, and suppliers certainly tell you they work, but I was unable to find a single source of information that actually provided data to support the idea that Styrofoam cones keep plants warmer in winter.

So I decided to do some testing of my own.

Days To Maturity – What Does It Mean?

Days to maturity, or days to harvest, is a number that can be found on most annual flower and vegetable seed packets. What does days to maturity mean? How can you use the number to grow more food and flowers in your garden?

Days to maturity is a very useful tool for selecting the right variety of seed and gardeners, especially in colder climates, should understand the term. This is even more important if you grow a vegetable garden.

Organic Gardening – Are You An Organic Gardener?

Organic Gardening – What is it? This should be a simple question, and many of you may think you know the answer, but the answer is more complicated than you think.

I consider myself an organic gardener – but some of you won’t agree because I do use some Roundup.

Can you garden organically and still use Roundup? Can you be ‘sort of’ organic and still consider yourself an organic gardener? Do organic gardeners make the best environmental choices?

Allium moly is a plant that most people do not recognize as being an onion or garlic. It is short with fairly wide leaves unlike most onions. It also has very vibrant yellow flowers. This great garden plant should be in every garden. It grows just about anywhere, sun, shade, wet or dry – but maybe not in a bog.

Hylomecon japonica is a special, collectors plant for the shady garden. It is rarely offered for sale, and seed from most seed exchanges will provide the wrong seed. This is a plant that is certainly worth hunting down.

Double Dormancy In Seed – Does It Exist?

In a previous post, Seed Dormancy – Are Seeds Really Dormant?, I discussed Seed Dormancy and presented a new way for gardeners to look at seed development and seed dormancy. Today I would like continue the discussion by looking at double dormancy and ask the question, does it really exist?

If you plant some peony or trillium seed in the fall you won’t see any green growth until the second spring – if you’re lucky. This is routinely described as an example of double dormancy – the seed needs two cold periods before they germinate. The two stratification (cold) periods overcome two dormancies, hence the name, double dormancy.

But is this really true? Do seeds like peony and trillium have have double dormancy? Does any seed have a double dormancy?
