Plant of the Month: Lilies
Fellow Gardeners..Hello Fellow Gardeners,
Gardening in August is often a hot and sweaty experience, so all the more reason to grab a cool drink and sit in the shade. All work and no play is a typical gardener’s experience as we tend to look at what we must do instead of admiring the lovely flowers, listening to birdsong and enjoying nature. Gardens are bodacious, bold and beautiful this month as dahlias, gladiolus, callas and other summer beauties strut their stuff. It’s time to enjoy your summer garden before plants pass their prime as it will be autumn before you know it. A nice comfortable place to sit and a good view to lazily admire all flora and fauna is an essential . In my back garden, I have the view, but not the seating. I did have a rather uncomfortable bistro set but that was needed elsewhere. It has become apparent that the lack of seating in the back garden is very inconvenient. I can't sit and admire the view (while trying to ignore all the weeding, deadheading and pruning I have yet to do - argh!) because there is not comfy spot to sit. I need one in the potager veggie garden and the other on the raised bed along the fence. These strategic locations will enable me to see the gardens from two points of view. Now the issue is trying to find the perfect bench and bistro set. I’m on the lookout and hope to find something soon before the summer is no more. Enjoy your August garden and may the weather be kind to us all. Cheers, Amanda August Plant of the Month

Summer is at its peak so dahlias, glads and other hot flora are at their prime while others have seen better days. Deadheading, supporting floppy plants, weeding, watering, inspecting for bugs and diseases are tasks that never seem to end. In a way it’s a good thing though as it gets us to take the time to not just assess our gardens, but to enjoy the loveliness of summer.

August Lawn Care
Although watering lawns is banned in Metro Vancouver this summer, it doesn’t hurt to beg the heavens for an inch of rain every week. Lawns that are not watered become weedy and prone to grubs including chafer beetles, sod webworms and leatherjackets. If you live where watering lawns is allowed, give them at least an inch a week. Water in the morning so the grass has the resources to survive the heat and summer conditions. Watering at night also contributes to lawn diseases such as leaf blight.
Avoid mowing the lawn too short, as this promotes shallow roots and attracts lawn grubs. For healthy grass, keep it about 3 inches high and remove no more than one-third of the blade each time you mow. Leave short clippings on the lawn if they don’t clump they are a good source of nitrogen and other nutrients. Wait for September to fertilize.

Roses in August
Keep roses well-watered during the summer to prevent ants from building nests in their roots. Cut off dead flower clusters just above an outward facing leaf that has 5 to 7 leaflets. This also applies when cutting roses for flower arrangements. For stems without foliage, cut canes back by ¼ to just above a node or side branch. For more on pruning roses click here. After each flush of blooms water well then fertilize with kelp meal, seaweed extract or fish fertilizer to promote healthy growth and more blossoms. Follow up watering thoroughly. Enrich the soil with an inch or two of compost mixed in around the roots. To promote more blossoms, apply a high phosphorous fertilizer (middle number highest ex: 6-8-6).
Ants Love Summer
Ants love to make nests in dry soil along driveways, inbetween pavers, as well as the garden where the soil is dry. An effective way to kill ants is to mix 3 parts sugar or honey to one part borax. Sprinkle the powder or globs of the tainted honey around plants. Another option is to make a paste by mixing in a few drops of water. Place it where they travel and on their ant hills. The ants will carry the back to the colony for the larvae to eat. Reapply as needed. Other options include liquid ant baits and diatomaceous earth. Use numerous strategies at once to ensure control. Apply a mulch to the soil to retain soil moisture and don’t forget to keep plants watered.
In the Veggie Garden
Vegetable Gardening
It’s time to harvest tomatoes, peppers, corn, eggplants (aubergines), beans, broccoli, cauliflower, kale, chard, zucchinis and other summer veggies. Harvest crops in the morning after the dew has evaporated and plants are dry. Zucchinis are best when small, the same goes for beans, but wait for green peppers to ripen and turn colour. To learn more about picking at the peak of perfection and how to harvest click Harvesting.

Onions, Garlic, Shallots & Potatoes
Onions, garlic, shallots: Snip off their flowers as soon as they appear to encourage large bulbs. Stop watering when their leaves yellow. Dig them up once plants wither and die back. Cure in a dry area for a week then store in a dry location.
Potatoes: Stop watering when their stems yellow and wither. After two weeks, dig them up and rub off any soil. Don’t rinse them as it promotes rotting. Store in paper bags or cardboard boxes in a cool and dark frost free area so they don’t turn green. Green potatoes are still edible, just peel off and discard any green skin. Discard all diseased potatoes, but keep any that were damaged during harvest. Just eat them asap and eat any that were damaged during harvesting as soon as possible. For more click on Potatoes

Homegrown Tomatoes: It’s tomato time. They do well when they receive the care they need, which is water, food, sun and space. Too much shade and/or too much nitrogen results in a lack of flowers, therefore fruit. Inconsistent watering causes split fruit, while blossom-end rot is from too little calcium and inadequate watering. Brown, withered, wilted and distorted lower leaves combined with unsightly blemished fruit is a blight. It’s a prevalent tomato disease this time of year.
Tame unruly tomatoes and hasten ripening by cutting stems off just above a cluster of fruit. Remove excess growth but cutting off suckers, preferably when they are small. Speeding up Tomato Harvest.

Epsom Salt on Tomatoes & Roses
Both tomatoes and roses benefit from Epsom salt as it assists with the absorption of nutrients, intensifies foliage and flower colours whilst speeding up the ripening of tomatoes. It contains magnesium sulphate, a micronutrient that plants need in small amounts. Use as a foliar spray or as a soil drench. Mix 2 tablespoons of Epsom salts in one gallon of water. Don’t spray plants in full sun as it will damage the foliage.
Composting: Add veggies scraps, non-weedy and seedy plants to the compost. Avoid adding cooked food, rice, bread, meat, fat and other animal products to prevent bad odours and rodents. Cover with a brown layer (torn newspapers, dried leaves, soil) to deter critters and fungus gnats. To learn more about composting and trouble shooting click on Composting.
Time for a Drink: It’s a tough time for wildlife including butterflies and bees. Help them get through the summer by placing shallow dishes of water in the garden. Add some flat rocks, pebbles and sand for them to rest on. Birdbaths not only provide a place for birds to cool down and have a drink, and they provide an attractive garden feature.

Start Your Winter Veggie Garden
Purchase starter plants at your local garden centre to get a jump on autumn and winter veggie gardening. To start plants from seed make sure you read the seed packets for suitable candidates and for sowing instructions. Winter hardy crops include arugula, beets, lettuce, endive, pac and boc choi, radicchio, radish, scallions and spinach. For more click on Winter Veggie Gardening.
Improve Soil with Cover Crops
To improve the soil in veggie gardens, plant a cover crop such as crimson clover, fall rye and winter peas, once crops are harvested. Cover crops grow throughout autumn through to spring, then they cut back and dug into the soil. This builds soil, adds nutrients and essential organic matter. For more information click on Cover Crops.
Plants Taking a Powder
Powdery Mildew: White talcum powder-like substances on garden phlox, cucumbers, squash, maple trees and many other plants is caused by a fungus called powdery mildew. Before spraying with baking soda or a milk solution, remove severely damaged foliage. To reduce infection, keep water off foliage, and don’t allow the soil to dry out. Note that even after treatment, infected leaves will not become healthy.
When Plants Wilt
Don’t be surprised when plants sag and wilt when temperatures pass 29° C (84.2°F) even if the soil is damp. Cool them down with a drink and provide temporary shade such as an umbrella, a tablecloth on a trellis, a propped up piece of cardboard etc. For a more permanent solution consider installing a pergola, arbour, or a tall plant on the south or west side of vulnerable plants. Alternatively, wait until autumn to move plants suffering from heat stroke to a shadier, cooler location to replace them with more heat loving candidates.
Reduce Watering: Keep soil moist by placing a 3 inch layer of mulch to reduce evaporation Before placing the mulch down, weed and water, especially if it is dry.

Watering Tips & Techniques
Use timers: Make your life easier by installing a timer to your outdoor faucet. Attach a garden hose with a sprinkler to the timer. Set the timer so the sprinklers have a run time of at least 45 minutes for each zone, two to three times per week.
Soaker Hoses & Drip Systems: Don’t rely solely on soaker hoses and drip irrigation to keep soil and roots moist. These systems generally take up 90 minutes to emit just an inch of water. Dig down to see how far and how deep the water has spread. If it isn’t going down to the roots, then hand-water or put on the sprinkler, then check the soil again.
Deep Long Soaks: Inadequate water leads to shallow roots that dry out easily, which quickly succumb to heat and drought. You may think you are giving plants an adequate amount, but you should really check. Use a trowel or a shovel to dig down to see how far it has gone down. When hand watering, allow the water to puddle a number of time before going to the next plant. Since dry soil sucks away any available moisture, water the entire area in between the plants. This keeps the ground wetter longer.

Time of Day: Water in the morning as plants are active during the day, but they are ‘resting’ in the evening. Consider it their breakfast as it gives them energy to suffer the slings and arrows of the day’s environmental conditions. Watering in the evening also encourages diseases, plus slugs and snails love to feast on the wet foliage.
Watering Flowering & Fruiting Plants: When plants are flowering fruiting, they are technically pregnant so make sure they are receiving adequate amounts of water and food. This is especially critical for tomatoes and other vegetables as well as roses, shrubs, vines and trees.

Water Trees, Shrubs & Hedges: Don’t forget to water all the plants in the garden including camellias, rhodos, azaleas and street trees. Brown, crispy leaves, especially at their edges (margins), ones that curl inwards, droop or show their backsides are signs of drought distress. If woody plants do not receive supplemental water during the summer year after year, they will eventually decline and die.
Saving water: Don’t salt the water when boiling veggies, pasta, rice and eggs as you can use it to water your plants. It’s good stuff as it contains beneficial plant nutrients. When we are lucky to get a summer shower, direct the rainwater from the gutters to downspouts into rain barrels. Note that most municipalities offer rain barrels to the public. Collect ‘grey water’ in a bucket when you shower, bail the water after a bath, recycle dirty dishwater by placing a wash basin in the sink. To learn more, click on Drought Gardening.
Getting Buggy With It
Summer Bugs: As plants struggle with the heat and dryness of summer they become prey to plant eating insects. Inspect both sides of plant foliage and at leaf axils, where the leaves meets the stems as that’s where insects hide.
To control caterpillars, use the Eco-friendly bactericide, Bacillus thuringiensis (Bt, Thuricide). It only affects caterpillars so avoid using near butterfly gardens. Stink bugs become a problem when the weather is hot and dry. Wear rubber gloves to plop them in a cup of soapy water or just squish them. They don’t bite, nor sting but they do ‘stink’ when touched and squished.
Don’t know what’s eating your plants? Go out into the garden at night with a flashlight to catch slugs, snails and other nocturnal plant eaters in the act. Plop them in a cup of salty, soapy water if you’re not too squeamish.

Beetlemania
Beetles are Here: Beetles turn foliage into lace as they eat the tissue between the veins of the leaf. Handpick beetles and place them in a cup of soapy, salted water and/or neem oil or pyrethrin. Plants are more susceptible to beetle attacks when they are suffering from the heat and drought. Reduce their stress by providing them with adequate water. To deter them plant onions, garlic, rue, tansy, parsley, thyme and other fragrant herbs. Rotate crops next year to further deter infestation. For more info click on Japanese beetles or Ten-lined June beetles.
Mollusks in the Garden
Critters & Birds in the Garden
Furry Faces: Like people, animals love fresh fruit and veggies. Keeping them away is often quite difficult with some produce ultimately being eaten by a furry face. To prevent cats and other critters from digging, place a few inches of straw, fallen leaves, newspapers, or wood chip mulch on top of the soil. Scare away birds and critters by tying shiny reflective tape on trees, and Whirligigs around the garden. Another option is to cover the crops with floating row covers or a cloches. For more click on Critters in the Garden.
Pruning in August
Cutting Plants Back: It’s not a good idea to cut back wilted, heat suffering plants as they might not recover. Water plants thoroughly, especially after pruning and feed with a high nitrogen plant food, kelp, fish fertilizer and/or compost. Refrain from pruning spring flowering plants, such as forsythias as they have already set their flower buds.
Prune: Tame unruly wisterias, grapes and fruit trees to promote more flowers/fruit. Remove suckers, watersprouts, spindly stems and anything that’s dead, diseased and broken. Here’s more on Pruning. To make pruning easier, use the correct Pruning Tools for the job. For personalized pruning instruction in your garden click on Pruning Registration. Available in Metro Vancouver.
Pruning Hedges & Conifers: This month is the last month to trim hedges including cedar (arborvitae), boxwood and other hedges. This gives the subsequent new foliage time to harden up before cold temperature arrives.

Dead Flowers & Seeds
Remove dead flowers: Clean up the garden, promote more flowers and prevent volunteer seedlings by cutting off the dead flowers from shrubs, perennials, annuals and summer bulbs. Wait until spring to deadhead lavenders as birds love their seeds
Collect Seeds: Pick them when dry and brown and store them in paper envelopes in a frost-free, dry place. Label with collection date & name. For more click on Collecting Seeds. Suitable plants to collect seeds from include hollyhocks, sunflowers, marigolds, sweet peas, peas, lettuce, carrots and beans.
Flowers for Pollinators: Daisies and other simple flowers attract the most pollinators, especiallt bees and butterflies. Don’t harvest all your non-fruiting veggies, allow them to flower. Radish, lettuce, carrots, onions and other veggie flowers are pollinator magnets. For more ways to help pollinators click here.

A Weedy Subject
Weeding: No matter what the weather or climate, unwanted plants will grow wherever they please. Make it easier to pull them out of the ground by wetting the soil first. To prevent them from spreading their seeds, pull them up before they flower and set seed. To further reduce their spread, don’t put seedy weeds in the compost. To control weeds with a herbicide, use organic types such as fatty acids, horticultural grade vinegar etc. Add a few drops of liquid dish soap to the spray bottle to help it adhere. Reapply at least every 7 days. Protect surrounding plants with cardboard and follow the instructions to the letter. Avoid Weed Block fabric as it does not deter weeds as they just grow on top of it and it impairs soil and plant health. For difficult to eradicate weeds such as bindweed and horsetails click here.
Water For All
Let's Have a Drink: The lack of rain during the heat of the summer affects all living things, not just plants. It's a difficult time for birds, butterflies, bees, dragonflies and all kinds of wildlife, especially ones with babies to provide for. Help them get through the summer by placing shallow dishes of water in the garden. Add some flat rocks, pebbles and sand for them to rest on. Birdbaths not only provide a place for birds to cool down and have a drink, they provide an attractive garden feature.
Ponds & Water Features: To keep the water clean, thin out plant growth and remove any leaf litter, algae and other organic debris. Replenish water that has evaporated in ponds and water gardens.

Pollinators & Hummers
Flowers for Pollinators: Bees, butterflies and other pollinating insects prefer simple flowers where they can easily access nectar and pollen. It just so happens that many vegetable plants fit the bill perfectly – if you allow them to flower. These include lettuce, spinach, carrots, radishes, chard, dill, kale and fennel. For more ways to help pollinators click here.
Keep Hummingbirds Humming: Keep feeders filled with a fresh and continuous supply of fresh nectar as the hotter it gets, the hungrier they become. Clean feeders before refilling by soaking them for 30 minutes in a solution of 1 part vinegar to 2 parts hot water, or 1 part bleach to 9 parts hot water. Rinse thoroughly and allow to dry before refilling them with nectar. Use ¼ cup white sugar to 1 cup boiled water. Only use white sugar and allow it to cool before adding to the feeder.

for the tropical Gardener
While working in Florida as horticultural consultant, it became apparent that there was a need for a book on tropical shrubs. There are so many wonderful shrubs to choose from, so I wrote a reference book to make the selections easier. Ornamental Tropical Shrubs includes pictures in full colour and information about the plants in point form. So if you live in the tropics and subtropics and need a reference book on tropical shrubs, or you just want to have a look-see click here.
