Greetings!

 

"I love spring anywhere, but if I could choose I would always greet it in a garden."
~Ruth Stout

What a wonderful season.  We have been enjoying this stunning weather and everybody wants to be outside!  

Dufferin Garden Centre has been just buzzing with trucks coming and going.  The annuals and hanging baskets this year are just stunning!  Have you picked up yours yet?  The combinations of the different annuals are beautiful.  The perennial section is brimming with spring-flowering perennials.  The bleeding hearts are in full bloom with creeping phlox in hot demand in the groundcover department!  Not to be out-done, the shrub block and treeland are full of plants in bud...we can't wait for the roses to burst into bloom!

With everyone spending their time outside, what projects are on your to-do list?  Planting some shade trees?  Looking for some privacy ideas?  Adding more perennials this year?  Perhaps a vegetable garden to grow some food closer to home.  Are you thinking of adding some tomatoes this year?  If so, read on...we have some info on growing these tasty summer gems!

Tomatoes Like it Hot!

Tomatoes are one of the most sought after plants in the spring.  They can be grown anywhere; from fields, to small gardens, to containers, to balconies, to hanging baskets.  Why do we grow them?  It's the taste of a sun-warmed, vine ripened fruit that will win you over!

Are you looking for tomatoes?  You've come to the right place.  We have some tips and tricks to help you grow a bountiful harvest this year!

Is a Tomato a Fruit or a Vegetable?

Brandywine Heirloom Tomato
Brandywine Tomato
The difference comes into question when talking to scientists and cooks.  Tomatoes, botanically is a fruit since tomatoes are the result of the pollination of a tomato flower.  Tomatoes also hold the seeds which can be used to grow more tomatoes.

However, culinary uses of tomatoes are found in savoury (not sweet) cooking.  Many of us are guilty in thinking it's a vegetable as most grocery stores sell the tomatoes with other vegetables that we associate with them.

Growing Successful Tomatoes:
- Start with short stocky seedlings with dark green leaves 
- prepare the garden with lots of compost as tomatoes are heavy feeders
- choose a sunny spot to grow your tomatoes, they need lots of warm sunshine (7 hours or more)
- plant the tomato seedling up the second set of leaves, firmly pat the soil around the plant...it's okay to bury these leaves, new roots will emerge along the buried stem
- add mulch under the plants to keep the soil moist during hot weather and prevents the soil splashing up on the plants
- water deeply 2-3 times a week and feed your tomatoes with a vegetable fertilizer for stimulating fruit (Off the Vine Fertilizer by Turf Revolution, see coupon below, available at Dufferin Garden Centre), high calcium levels will help to combat blossom-end rot
- use a cage or stake for support and to make harvest easier, this also reduces the risk of diseases and insects by getting them off the ground
- once tomato is 3' tall, remove the leaves within the bottom 2" of stem as they are usually the first leaves to develop fungus problems
- pinch and remove suckers that develop in the crotch joint of two branches (they won't bear fruit and will take energy away from the plant).  Prune some of the leaves to allow sunlight to reach the fruit but not too much as it's these leaves that are processing the food and energy for the rest of the plant
- in order to improve flavour, promote growth, increase harvest and protect from insects, consider using companion plants such as chives, onions, garlic, basil or marigolds

Terms to Know:

Determinate Varieties:
- bush tomatoes fall into this category as they grow to a compact height
- they stop growing when fruit sets and ripen at the same time (usually within 2 weeks!)
- perfect for container gardening as there is limited amount of caging or staking needed
- Look for:  Better Bush, Caribe, Empire, Green Zebra, Patio, Roma, Tiny Tim

Indeterminate Varieties:
- vining tomatoes include heirlooms and can grow up to a large (6') heavy plant
- these tomatoes will continue to grow, set fruit and ripen throughout the growing season until frost
- some pruning will be required (removing the suckers) as well as caging or staking to keep your tomatoes in check
- Look for:  Beefsteak, Brandywine, Celebrity, Early Girl

Hybrid Seed
- comes from a cross breeding two or more different varieties in order to obtain a specific set of characteristics
- if the seeds were saved, they would not have the same traits as your original plants
- the seeds cannot be saved and planted next year
- Varieties include: Early Girl, Sweet 100

Open-Pollinated
- these varieties hold onto the parents' characteristics generation after generation
- important if you want to save the seeds from  year to year

Heirloom Tomatoes
- an open-pollinated variety that is capable of breeding true from seed
- save the seeds and next year, when planted, the same tomato will grow (just as generations before us)
- usually a variety that has been passed down through several generations and valued for specific characteristics

Things to Watch for:

Blossom End Rot
- the plant can't get enough nutrients to the end of the fruit
- the soil is on the acidic side and prevents the plant from absorbing the necessary nutrients therefore turning the end of the tomato black
- solution :  add dolomite lime or chicken manure to the soil before and when planting to neutralize the acidicity

Early Blight
- fungi causing leaf spots to form on the tomato leaves
- avoid watering the leaves
- mulch after planting to retain soil moisture
- prune off the lower leaves to increase air flow

Tomato Worms
- these pesky worms are green with a white v-shaped marks along it's side...and a black 'horn' projecting from it's last abdominal section
- they are 3.5" - 4" long when mature and become the hummingbird moth when adult
- Hornworm Tomato Caterpillars look fierce but can be easily caught in the still of the night
- try going out with a flashlight at night and they will be out in the open ready to plucking into a bucket with soapy water

What to Plant with Tomatoes

Companion Gardening is all about plants helping plants.  By planting certain plants in proximity to each other, it is believed that they will benefit in increasing taste, and deterring many insects and pests.  The following list are plants that are suggested companions to tomatoes.

Chives, onions and garlic - odour helps to deter many insects and pests
Borage - help to deter Tomato Hornworm Caterpillar
Marigolds - help deter harmful nematodes from attacking tomatoes
Basil - increases vigor and flavour of both crops
Spinach, lettuce, arugula - stays small and grows better during the heat of the summer when shaded by growing tomatoes
Carrots, Lemon Balm, Mint, Parsley

Avoid:
Corn, Fennel, Kohlrabi, Potatoes, Cabbage, Eggplant and Peppers

We wish you a bountiful harvest of vegetables and fruits this season - especially tomatoes.  If you have any questions, please don't hesitate to come and see us, ask on Facebook or through our Website.

Eco-Tip :: The Benefits of Mulch

 

Shredded Bark MulchMulching has become a popular way to complete your gardens.  It adds many benefits:
  • helps to control weeds    
  • reduces watering by retaining soil moisture
  • nature's insulator by keeping soil cool in the summer and protecting plants in the winter
  • minimizes temperature fluctuations such as the 'freeze - thaw' in the winter
  • creates a "well cared for look" to your garden
It is recommended that weed barrier cloth NOT to be placed under the mulch.  Wood particles provide aeration and reduce soil compaction, while returning carbon into the garden.  Know where your mulch comes from to ensure that it is free from contaminates and harmful insects.  

Mulch can be used on soil areas such as:
  • flowerbeds
  • bases of trees (avoid heaping the mulch up around the base - create a saucer by tapering the mulch away from the trunk)
  • children's play areas
  • pathways
  • dog kennels
The benefits of mulching far exceed the decision not to mulch.  The decomposition of wood mulch reduces soil compaction that opens areas for roots to expand through the soil seeking out nutrients.  Decomposition returns micronutrients and minerals into your planting bed, including carbon, an essential element for plant growth.

Mulch is available at Dufferin Garden Centre in bulk or in bags.

Feature Plant :: Bleeding Hearts (Dicentra)  

 

Such a wonderful family of spring-blooming perennials.  When looking at the old

Bleeding Heart
Old Fashioned Bleeding Heart (Dicentra)

-fashioned Bleeding Heart, it's easy to see where it got it's name!  The delicate heart-shaped flowers hang on arching stems in early spring about the light green foliage.  This plant prefers the shade away from the hot afternoon sun with rich, moist soils.  After the plant has finished blooming, cut back to encourage new growth, although it may go dormant if the soil and area is too hot and dry.   


Height and Spread:  30"

Design Tips:  try planting in a woodland setting grouped with later emerging ferns and hostas to help fill the space when this bleeding heart goes dormant mid-summer. 


Check out some of the other varieties in the family: 


White Bleeding Hearts - similar to the Old-Fashioned but with white dangling flowers instead

Gold Heart Bleeding Heart - rosy red flowers with gold foliage

Fern-Leaf Bleeding Hearts: such as 'Luxuriant' or 'Burning Hearts' - shorter varieties with dainty foliage but a longer bloom period

Gardening 101 :: Pests and Diseases to Watch with Roses  


Green Caterpillars
Green Caterpillars on Roses
Powdery Mildew: covers the top surface of leaves and flower buds causing the leaves to crumple and become distorted.  It may not kill the plant but it does make them very unsightly and affects the look of the foliage and blooms.  Will most likely be a problem due to our wet and cool spring as there has been a lot of moisture.  Pre-treat with Serenade Garden to prevent this fungus.  Treat with a fungicide such as Safer's 3 in 1 Garden Spray or Safer's Defender Garden Fungicide or Lime Sulphur.

Black Spot:  is a fungus that starts by growing in colonies on rose leaves.  It is found midsummer on the rose leaf with fuzzy edged rounded blackish or purplish spots and will spread across the leaf until it finally kills it (leaf turns yellow around the black spot).  Remove and destroy any infected leaves including the leaves that have fallen to the ground and put them in the garbage NOT compost.  Start your pre-treatment spraying now to avoid this fungus with Serenade Garden, Green Earth Bordo Copper Spray, Safer's 3 in 1 Garden Spray or Safer's Defender Garden Fungicide or Lime Sulphur.

Cane Borers:  are the larvae of sawflies, carpenter bees and some wasps that enter the rose through the tops of pruned canes. These pests lay their eggs on the freshly pruned stems of roses in the late spring or early summer. The eggs hatch and the larvae bore and eat their way into the centre of the plant down the length of the cane.  Wilting and dying foliage at the top of the bush with yellowing leaves which drop off can also indicate the presence of cane borers.  Prune the bush below any areas of pith damage.  Put a little dab of Elmer's white glue on any pruning cuts and if you add a drop of food colouring to the glue, you can tell which canes you have sealed.

Aphids:  are very small insects usually light to lime green but can also be brown, red or black that feed on the tender new growth.  They have sucking mouth parts that puncture the soft tissues and suck out the juices.  As they feed they excrete a sticky honeydew-like substance that is attractive to ants.  Aphids can overwinter as tiny black eggs on the stem of the rose and hatch just in time to feast on the new growth.  This is why applying dormant oil in the spring is so important for roses as the oil suffocates the overwintering eggs.  Treat aphids with Safer's 3 in 1 Garden Spray or Safer's Insecticidal Soap.

Green Caterpillars:  there are many different types of green caterpillars that feast on roses that are the larvae for wasps, moths and other insects.  If you monitor your roses often and closely, you should be able to catch an infestation before it devours your plant.  They can usually be found on the underside of leaves so lift up the leaves and pluck off what you see.  You can destroy the larvae be either squeezing them with your fingers or dropping them into a pail with soapy water.  An application of Safer's End-All Insecticide or BTK can be done once you see the pest, spray to dripping and don't forget the undersides of the leaves.

Remember:
- the best way to fight these pests and diseases is with a healthy and happy plant.  Roses enjoy a rich loam soil with lots compost.  Feed them regularly with rose food (Turf Revolution Rose N' Bloom) and banana peels (Tear the peels or cut them into small pieces and bury them around your roses (using three peels per bush at one time)  Banana peels add potassium to help with flower production).

All products mentioned are available at the Dufferin Garden Centre (except the bananas!)

Cedar's Corner :: Helping the Tomatoes Grow 

 

Hello, my Pint-Sized potters!  Are you enjoying this wonderful outside weather.  Some days it gets a little for us with fur coats so I try and find a cooler spot.  Do you like to help out in the garden?  I bet you do.  It's a lot of fun to get down and dirty with the plants.  I think a good job for you would be to help with the watering.  When you use your watering can remember to only aim for the roots.  Too much water on the leaves is not a good thing!

Do you like to eat...I know I do!  The next time you have scrambled eggs, don't let Mom and Dad throw out the egg shells...I have a special place for them.  Did you have a nice big glass of milk with your scrambled eggs?  Your milk (and other milk products) contains mineral called calcium which helps to build strong bones, teeth and is needed for muscle growth.  Where else can you find calcium?...In whole grains, green vegetables, sardines, salmon, soybeans and peanuts.

Do you know who else needs calcium?  Tomatoes do!  They need them for cell growth and division.  When tomatoes (and peppers) don't get enough calcium, they have underdeveloped leaves or blossom-end rot.  This is when the end of the fruit doesn't develop properly causing a dark, flattened or sunken leathery-appearing spot, sometimes including half the fruit.

Time to feed your plants!  Adding those crushed egg shells from your breakfast around the base of the tomatoes (and peppers) will certainly be a welcome additions.  Or, add Hen Manure which has naturally occurring calcium (organic fertilizer).

While you are in the mode of feeding your plants, don't forget to replenish the nutrients of your other plants.  Remember to give your hanging baskets and annuals a shot of fertilizer, such as Parkwood Transplant Fertilizer (10-15-10).  Now is also a good time to feed your lawn with Green Acres by Turf Revolution or Parkwood 21-6-12 Lawn Food.

Ahh, time for another nap in the shade!
