Tree Planting: A Step by Step Guide

Nature lover or not, everyone should contemplate adding a tree to their home’s outdoor space. We could go on and on about the environmental benefits of trees, but beyond their natural effect, trees can be a central part of your landscape design. Over the years, any tree – pine, oak, apple, maple, cherry – will grow along with your family. When you do decide to plant a tree on your property, it’s important that you choose the right location for your tree.

Why Tree Location Matters

When you’re planting a little seedling, location might not seem to matter much. Whether it’s in a corner near a fence or in the centre of your yard, does it matter? You need to think about the future size of the tree, sunlight requirements, soil requirements, and proximity to impediments like the driveway or fence. There are also safety considerations if tree roots will affect water lines or branches will grow to obstruct power lines. Location absolutely matters. In terms of sunlight and soil conditions, this will vary based on the tree species. Talk to an expert at Ritchie Feed & Seed to discuss the right location on your property.

Step 1: Dig Your Planting Hole

It is important that the hole is the right size for the root ball – it shouldn’t be too big or too small. How do you know the right size? As a general rule, dig deeper than the depth of the container you buy the tree in. The hole should also be 3” wider than the width of the container (which you’ll remove later). Keep the soil that you dig, because you’ll reincorporate this with fresh soil later.

Step 2: Preparing the Root Ball

Remove excess packing materials around the base of the tree. Remove the pot. If necessary, gently loosen the tree roots if they’re tightly bunched together to keep your tree grow in solidly.

Step 3: Time to Fertilize

Add transplant fertilizer or bone meal fertilizer to the planting hole. MYKE for shrubs and trees is added now. To help promote better root growth, ask us at Ritchie for more ifnromation about MYKE. Set your tree in the centre of the hole. Orient the tree so that the most “attractive” side of the tree faces where it will be seen most as it grows over the years.

Step 4: Fill the Hole

Back-fill the hole with high-quality fresh planting soil from your local Ritchie Feed & Seed garden centre, mixed with soil from the planting hole. Tamp the soil and water well.

Step 5: Continual Care

Water the tree deeply on a weekly basis until the fall. Consider installing a stake to keep the tree stable in rough weather. You won’t need to fertilize again during the first 12 months, but regular watering is very important.

If you have any further questions about planting a tree in your outdoor space or would like to visit our garden centre to pick out a tree for purchase, Ritchie Feed & Seed is here to help. We offer more than 100 varieties of trees for planting, including ornamental trees and fruit trees.

Why You Should Start Gardening This Spring

Gardening is one of the world’s most rewarding hobbies, and all it takes to get started is soil, water, seeds, and sunlight. Gardening is a wonderful hobby for people of all ages. Children can learn about nature and science and take a sense of ownership from each plant they help nurture. For adults, it can be a great way to blow off steam. For seniors, gardening is the perfect activity to keep the mind and body healthy. Let’s explore the many benefits of home gardening.

Grow Your Own Veggies

Grow lettuce, cucumbers, and tomatoes for an easy spring salad whenever you choose. Grow cilantro for taco night, fresh oregano and basil to make a delicious homemade pasta sauce, and garnish any dish with parsley. Save money, eat healthier, and enjoy peace of mind as you grow healthy, filling, organic fruit, vegetables, and herbs.

Nature Has Never Been Closer

In our lives of hustle and bustle, we spend our days moving from screen to screen. The closest we get to nature is on the walk from the front door to the car. If you wished you could get closer to nature, now is your chance. Gardening is a way to get elbows deep in nature, and you can enjoy a more beautiful landscaped view once the hard work is done.

It Gets Easier

Once the hard part is done, the rest is just watering and mowing. If you are a nature lover and the greenery has magnetic attraction towards you, you’ll notice that gardening calms your nerves. Once you are finished gardening you can pull up a lawn chair and a good book or beer and enjoy the beautiful atmosphere you have created.

Exercise Without the Gym

You can burn fat, tone your legs and strengthen your muscles all the while doing something you love. It’s a lot easier than driving to the gym and a lot more affordable than investing in a treadmill you never use.

Challenge Yourself

Gardening is a rewarding challenge. You’re going to have to learn all about soil types, watering requirements, sunlight conditions, and much more. You’re going to be excited for rain and anxious about pests and weeds. You’re going to feel pride when you see your first tulip bloom, frustration when you get a grub infestation, triumph when you nurse limp hydrangeas back to life, and sadness when rabbits get to your carrots before you do. Through it all, you’ll learn and improve as a gardener and enjoy a sense of pride and accomplishment along the way.

It Makes Your Heart Sing

When the first of the seedlings pop out, it is a milestone moment. Something like watching your baby grow. We all like it when our hard work pays off and this is a great way to let go of the stress and occupy yourself with something more productive.
For all your gardening needs, Ritchie Feed & Seed is on your side. With convenient locations in Ottawa, Stittsville, Richmond, Brockville, and Winchester, we have been serving gardeners just like you since the 1930s!

 Preparing the soil for a new crop

  1. Turn over the soil to a depth of 10-15cm. 
  2. Add soil amendments such as black earth and topsoil.
  3. Rake well and level the soil, creating a gradual slope away from the house to prevent drainage problems.
  4. Roll the area to firm up the soil.  Water the soil afterwards to settle the soil.

Starting Bulbs & Seeds Indoors

 

Why are we starting seeds indoors?

There are many reasons why are starting seeds indoors.  Some people are looking for varieties that they cannot find otherwise.  Some people like to get a head start on the season and be involved in growing as early as possible.  Another reason for starting your own plants indoors is to save some money when you have a large amount of plants to grow.  Yet another reason to start your own plants indoors is to ensure how they are gown, and what products are used on them.

 

What are the differences between seeds, cuttings, bulbs, and bareroot perennials?

Seeds come from the plants after they flowers.  Seeds can vary in many ways, from being extremely small to very large, thick skinned or thin skinned and a wide variety of shapes and colours.  Cuttings are made from a mother plant and then planted in growing medium. These cuttings or slips will then grow roots and product a new plant. Bulbs are basically food storage containers for plants. This means that everything needed to get the plant to grow is stored in the bulb itself.  Bareroot perennials are root masses that are stored in peat moss after being split and prepared by the nursery.  Unlike bulbs, they do not have any food stored in them and will need to be fertilized just like seedlings and cuttings.

 

What soil should I use when I start seeds and bulbs indoors?

Ideally the soil used indoors should be weed, insect and fungus free.  A sterilized soil is not available for sale, however, a soil less mix does offer the same benefits as well as a few others.  “Pro-Mix” is a mixture of peat moss, vermiculite, perlite, and nutrients.  This is an excellent choice when starting seeds indoors as it is light and less susceptible to the problems often associated with regular soil.

 

What is damping off?

Damping off is a disease that strikes seedlings during their very early development.  Characterized by a spindly stem that blackens at the point of contact with the soil, damping off will cause the seedlings to break and die.  This can wipe out an entire seeding tray in a day or less. This disease is usually caused  by excess moisture and poor ventilation.  In order to prevent this disease you should ensure that the seeding trays are not too overcrowded, which helps to allow for better ventilation, and also ensure the medium is not over-watered.  There is a no treatment for this disease.

 

Should I use fertilizer when I am starting seeds indoors?

After the seedlings have reached a 3 leaf stage you can use a transplanter/starting fertilizer at half the recommended rate of dilution.  When you are growing bare root perennials you may use the transplanter as soon as you plant the roots.

 

 

Why do my plants get spindly and thin when I grow them indoors?

When plants do not have enough light they grow tall and spindly searching for light.  It is important to use a light unit that will give a full spectrum of light to the seedlings to allow them to develop normally.

 

How do I deal with white fungus on my soil?

It is not uncommon to get powdery mildew on your soil when you have high humidity as well as poor ventilation.  In order to prevent this problem, maintain plant trays that are thinned properly allowing for better air flow.  In addition to this, do not over water, it is bad for the plant as well as bad for the soil.

 

What is the difference between scarifying and stratification?

Some seeds have very specific requirements in order to get them to germinate.  Scarifying is the act of softening the outer shell of the seed through scratching or cutting the seed.  Stratification is the act of pre chilling or heating seeds before planting them.  Most plants that have special requirements to germinate their seeds will list these requirements on the back of the seed package.  For those who like to collect and trade seeds with others, a book such as “From Seed To Bloom” would be very helpful in determining the seeds needs.

 

Why should I not use water directly from the tap when I water seedlings?

Water from the tap is cold, very cold in fact, and will chill the seedling every time you water them.  The best thing to do is to have tepid water available for when you are watering your seeding trays and potted perennials and bulbs.  When it comes to seeding trays, ideally you should immerse the tray in another tray filled with tepid water, then let the seeding tray stand to drain.  This is better than watering from the top, and diminishes over watering.
