Seed to Table Quick Tip!

Using Trellises 

Supporting some plants with trellises in your garden is an excellent way to optimize space, promote healthier plants, and increase yield. The following three garden favourites benefit greatly from vertical support, keeping them off the ground, reducing disease risk, and making harvesting easier. 

Tomatoes are vining plants that can sprawl if left unsupported. Indeterminate tomato varieties grow throughout the season, reaching considerable heights and producing abundant fruit. A sturdy trellis system provides essential support and prevents the plants from drooping or breaking under the weight of the tomatoes. Install trellises, such as cages or twine, early in the season and, as the tomato plant grows, gently guide the main stem along the trellis, securing it with soft ties, clips, or twine. 

Cucumbers produce long, trailing vines, and curly tendrils. A trellis allows cucumbers to grow vertically, saving space and facilitating better air flow that might prevent disease like powdery mildew from taking hold. Install a trellis or a sturdy support structure when you plant your seedling and ensure that it’s tall enough to accommodate the cucumber’s growth. You can train vines to climb the trellis by gently guiding the tendrils, but don’t worry if you forget–the plant will find its way. 

Peas are climbing plants that naturally send out tendrils to grip onto supports as they grow. Without a support structure in place, pea plants will climb each other, or neighbouring plants. When planting peas, set up the trellis along the row, about two to three inches from where the seeds have been planted. Avoid pulling or forcing the vines onto the trellis, as this can damage the delicate plants. You can buy netting specifically designed for peas.

Choosing the right trellis material is not as crucial as you may think. Sturdy materials like bamboo poles, wooden stakes, or metal cages work well, as do strings, netting, or fences. Ensure that the trellis is firmly anchored into the ground to withstand the weight of the growing plants and strong winds.

What is Seed to Table?

Seed to Table is a low-input growing initiative that goes through each of the steps in a gardening journey. Learn how food comes full circle from the seed to your plate and how your garden can (more) fully provide from planting to preparing and preserving. The classes and resources in this initiative will help you to:

  • Become increasingly self-sufficient
  • Save money
  • Reduce waste

What is a circular economy?

A circular economy eliminates waste and pollution, and conserves resources. It is a shift from a throw-away to a circular mindset to extend the lifecycle of goods, food, and resources through better design and continuous reuse, so nothing goes to waste.

Tips & Tricks

PLANNINGYou can start this part of the cycle anytime. It may simply mean you have to consider what/where you can grow in accordance to the time of year. You can grow year-round! 
Grow what you will use – think about what you and or your family likes to eat
Planning will help you reduce waste by avoiding the pitfalls of impulse buying, putting the wrong plant in the wrong place etc.  
Discover what is successful in your neighbourhood by visiting a community garden and/or chatting with neighbours. Markets and local growers can also provide insights. Take a class.  
Create a diagram on paper and use cutouts drawn to scale to help you plan where to place garden beds, shrubs, trees, and other garden features. It’s easier than having to move them with a shovel.
Use a temporary garden such as grow bags until you can determine the best location for a kitchen garden vegetable bed. They can be moved if needed to improve plant growth. Because the angle of position of the sun changes over the growing season, it can take a full season to learn where to site a vegetable bed. The sun and wind exposure of the garden will affect what plants can be grown and will thrive. Select the location carefully and you will be rewarded.
SEED STARTINGWinter sowing is great for starting seeds that required a cold period (stratification) to germinate. Vegetables such as cabbage, spinach, kale, Swiss chard do well when winter sown.
Tuck Tape, an exterior insulation sheathing tape, works well for sealing winter sowing containers. It does not peel off the containers in outdoor weather conditions. Look for Tuck Tape with the insulation in home improvement stores.
Watering – When starting plants from seed, it is important to keep the soil that the seed is planted in moist, but not wet. The surface should feel damp to the touch. The soil should be moist several centimetres into the container. To help retain moisture use a plastic cover or reuse saran wrap. Uncover when plants start growing and use a mister to keep the moisture level the same until the seedling has its first set of true leaves . At that time, the plant needs deeper watering less often. Once the seedling has reached that stage, the surface of the growing medium can dry out between waterings. For plant health and the prevention of rot, watering in the morning is recommended.
Confused what to start when? Check out our resource page for handy seed starting charts and tables.
RAISING YOUR PLANTSHarden off any indoor starts before moving them into a permanent outdoor home. This is getting them used to the intensity of natural light and other outdoor conditions gradually.

Water saving tips from participants:
– bring a bucket with you into the shower to capture water you can use for plants
– save unsalted cooking water – once it has cooled, use it to water plants
– when rinsing vegetables, fruit, rice or beans collect rinse water in a bucket below your colander
MAINTAINING YOUR PLANTSConsider tucking herb starts into floral containers (make a great filler) or empty spots in the garden. Be careful with mint in the garden as it does like to spread.
If you purchase soil, mulch, or compost in bags, save the bags to reuse. They are made from a heavy plastic and are great for refilling at self-serve bulk bins. They can also be used as a garden tote for gathering weeds when caring for the garden. Use the bags to store leaves collected in the fall to use in the spring.
Check your plants regularly for pest damage. Know what plants look like regularly and with damage. Learn how to deal with pests. Some pests to look out for:
– Aphids – common, especially on stressed plants – spray off with the hose. Spray every few days until eliminated
– Cabbage moth caterpillars – check your brassicas for holes – pick off caterpillars, protect plants with netting or row cover
– Lygus bugs – like several crop plants and larvae are voracious eaters – squish or vaccuum off
On indeterminate (vining) tomatoes make sure to pinch off growth that is 45 degrees to the stem (usually between stem and main leaves/branch) as this will improve fruiting. Note suckers can be replanted. Near the end of August remove most of the leaves to encourage ripening of the fruit. Monitor for frosts and remove green fruit before frost and ripen indoors in a paper bag. Consider covering plants if frost is light – old blankets work fine but keep them raised off the plant as much as possible.
HARVESTING & PROCESSINGLearn how to prepare and use the whole edible plant. For example, make pesto with carrot tops and save vegetable ends in the freezer to make soup stock when enough is collected. Find a way to use the leaves of cabbage plants as well as the heads. Save the dry, papery skins of onions to colour eggs.
Make sure to harvest your garlic scapes (see resources below), usually in July. These make great pesto, can be used in place of garlic cloves or be cut up into salads.
If flower heads are starting to form on your greens pinch them off as they will make plants bitter.
Eat flowers and seed-pods. Many flowers are edible including squash (eat the males), arugula and radishes. Green radish pods are also quite tasty.
Explore the many options for herb preservation – many can be dried, some can be frozen, they can be added into butter, vinegar or oil.
Consider preserving greens such as beet tops – they can be blanched (boiled for 2 minutes than cooled in ice water) and frozen to preserve nutrients. They work well in recipes in place of frozen spinach. Kale and other brassica greens as well as spinach can be similarly preserved.
Explore dehydrating vegetables – many vegetables can be made into chips in the oven or in a dehydrator. You can prepare your own soup stocks by dehydrating as well.
Fill empty spaces with succession plants – greens and radishes can be sown mid-August for a second crop. Cover-crops such as fall/winter rye can also be planted after other plants are harvested.
Harvest tomatoes before they are fully ripe (when they have a bit of colour). They can ripen off the vine (in paper bags works well). They will still taste good and then the plant will make more fruit.
Potatoes store better if they are properly cured. Spread them out in a well ventilated area under a cover to prevent light exposure for two weeks. To test if they have cured, the skins should remain intact and firm if rubbed with your thumb. After curing rub excess soil from the potato. Do not wash them.
WRAPPING-UPMake sure you water in any perennials (including trees and shrubs) really well before winter to ensure there is ground moisture in case of a Chinook and for spring. For deciduous plants reduce watering slowly until the end of September. In October, after leaf drop/leaf die-back water well again before the ground freezes (usually end of October). Continue to water evergreen plants until the ground freezes. Pile salt-free snow on beds as insulation / source of water. Mulch plants well to help with insulation during Chinooks (however don’t pile mulch against stems/trunks)
Harvest any frost-sensitive plants (e.g., tomatoes, peppers, beans) regularly before the last frost (approx. September 15). Greens and brassicas can tolerate frost so don’t rip them out. Consider a last harvest before ground freeze (near end of October). Carrots and parsnips sweeten up more with a frost.
Leave in roots of above ground vegetables behind when harvesting – these will feed the soil biology! Cut off plants at soil-level. For root crops try to minimize soil disturbance by removing plants one at a time. Don’t leave soil bare – mulch with compost, wood, straw (may need to net straw if winds affect your property) or pellets or consider a cover-crop.
Plant hardneck garlic in early October for a good crop next year.
Sow spinach seeds in mid to late October for an early start in spring. They will come up when they are ready!
Spend a few minutes reflecting on the season – what worked well, what didn’t. What varieties of vegetables or flowers were most successful in your garden? Are there pests you can research over winter to have preventative methods ready for spring?
Clean your tools well before putting them away for the season. Dirt will wear out your tools faster. Oil handles with lindseed oil.

New Tips & Tricks will be added throughout the season – check back regularly for updates!
