Measuring Light for Indoor Houseplants By Jim Hole During my November 23 session on grow lights, I spent quite a bit of time talking about the science of light energy that plants require to optimize growth. One thing that surprised me, was the number of attendees who had light meter apps on their smart phones. I guess that I shouldn’t have been surprised given the vast number of apps currently available. Having an app that measures light intensity really isn’t all that surprising. Naturally, a number of attendees asked if these light meter apps were suitable for measuring the kind of light e ..read more

Prevent Sun Scald and Frost Crack on Your Trees

Prevent Sun Scald and Frost Crack on Your Trees Warm sunny weather can be a great break for us during our cold winters, but it can play havoc on your dormant trees. Sun Scald and Frost Crack are two problems you probably won't see evidence of until spring. Direct sunlight and fluctuating winter temperatures are to blame for both of these unsightly damages—and they can be (and need to be) prevented right now! Sun Scald Sun Scald is caused by mild day time temperatures and direct sunlight warming the tree bark enough that some cells "wake up" out of dormancy and become active. They are tricked i ..read more

Benefits of Biochar

Benefits of Biochar By Jim Hole Bamboo Biochar? You’re probably wondering, ‘What the heck is bamboo biochar’? Well, I’ll start with biochar. Biochar is plant fibre that has been heat treated but not burned. The heat treatment is called ‘pyrolysis’ which involves super heating the plant fibre—without a flame—and leaving behind just the black, carbon-fibre skeleton. If you think of a log from a fire pit, the gray-white ash is the combusted or burned fibre but the charred, deep-black portion of the log is more like biochar. Here at Hole’s Greenhouses we carry Pure Life Carbon’s Absolute Carbon ..read more

Can I Still Plant?

Can I Still Plant? by Maria Beers At this time of the year, I get asked everyday if this is still a good time to plant. The fact is that for many plants now is actually THE BEST time to plant! With the days getting shorter and colder, plants switch to using all their energy preparing for winter, not new growth. Soon leaves will start to drop, the sap stream will stop and 100% of the energy will go into root development. And while the air temperature feels colder, the soil is still warm enough for plants to settle in. Any plants that you buy now will probably be root bound after growing in ..read more

Dwarf Trees for Small Spaces

By Jim Hole The trend towards smaller yards, quite literally, narrows the choice of trees that perform well in small spaces. And if you have a skinny house, ipso facto, you will also have a skinny yard. So if you want to grow a tree or two, that means you shouldn’t transplant trees that will become sprawling giants. The good news is that bigger doesn’t mean better when it comes to trees, and some of the very best varieties have a smaller stature without sacrificing any beauty. A bit of science So, why are some trees much sm ..read more

Planting Root Bound Trees, Shrubs & Perennials

Planting Root Bound Trees, Shrubs & PerennialsYou’ve bought a new plant, you have the supplies to start, but do you know how to properly tend to the roots before planting? A common mistake made by many planters is taking their new plant out of the pot they buy it in and plopping it directly into the ground. Trees, shrubs and perennials bought at greenhouses and nurseries often sit in the same pot for weeks, if not months. As a result of this they become extremely root bound with nowhere for their roots to grow. A root bound plant means that the roots have filled the entire pot, often creat ..read more

Confusing Beauties

Confusing BeautiesBy Jim HoleIf floral beauty is judged by popularity then petunias would surely wear the crown. When I look around the yards and streets of Canadian cities, petunias dominate. Today, they are grown in everything from hanging baskets to patio pots to flowerbeds, with some varieties are even used as annual, quasi-hedges.   There is little doubt that the ascent of petunias to the top of the bedding plant world has much to do with their beauty and diversity. But it’s the depth and richness of their genes that has allowed them to reach that lofty height. Most of the garden petunia ..read more

The 'Dirt' on HydrangeasBy Jim Hole Fact or Fiction? ‘You can change the colour of your hydrangea flowers by making the soil acidic.’ Hydrangeas are some of our most spectacular flowering shrubs. And while there are over a dozen great varieties that grow beautifully on the prairies, there are those among us who just can’t resist the challenge of changing a pink flowered hydrangea to one that flowers blue or vice versa. Today there are over a dozen varieties that we can grow here successfully. But can one really change hydrangea flower colour? The answer is yes…well, sort of. Changing the co ..read more
