Phil’s Garden Tips & Tricks for July 2022
Phil Thornburg • July 5, 2022
Wow! We just finished our wettest and coolest spring in over 80 years...who knows what July will be like!
June tips ‛n’ tricks:
- Plant the warm season annuals (whether you plant flowers or vegetables). These are petunias, impatiens, eggplants, tomatoes, tomatillos, golden berries, peppers, corn, basil, cucumbers and more.
- Fertilizing your annuals every two weeks with a natural fertilizer will cause them to grow well and produce. This would be a fertilizer not derived from petroleum but from manure, kelp, shells, blood, bone, rock or feathers. Remember, too much nitrogen simply gives lots of leaves but not much fruit. For a veggie bed, a ‘balanced’ fertilizer is best. This will be one that has the three letters representing nitrogen, phosphorus and potassium (N, P, K), like 5-4-3 or 4-3-2, where the first number is the highest, but not a lot higher than the other two.
- Mow regularly. Set your lawn mower at your favorite high setting for the rest of the summer until October. Keeping the grass longer during the hot months helps to shade the roots and keep the grass stay greener and healthier.
- Keep on top of the weeds. The rainy season is basically over and there will soon be less weeds to pull because the warm rain is no longer with us. If you’re in a hurry, you can simply toss the weeds (ones not going to seed) out in the sunny part of the bed, and they will dry up right there by the end of the day. Don’t do this on a rainy cloudy day because they just might strike root and grow again! Also, put the ones with seeds in the debris bin.
- Water everything as needed, one inch per week (at a minimum) for the lawn, and half an inch for the shrubs. This is a standard rule of thumb for an average warm, dry June week.
- Slug bait is still important to put out. Use pet-safe bait.
- Prune flowering shrubs or perennials after they finish blooming if they need it.
- Check the rhodies and azaleas for weevils. Nematodes or insect tape can be used to combat them. Also, check to see if you have lace bug damage on the leaves. It usually shows up later in the summer. They suck the chlorophyll out of the leaf cells and make the leaves look discolored. They can be somewhat controlled by a predator called green or brown lace wings. You can purchase the eggs of these predators locally.
- Deadhead your rhodies. This will make them look neater and bloom more next year.
- Check for aphids and cabbage worms on veggies or roses and, if needed, choose your method of action.
- Continue to take care of coddling moths and scabs on apples and pears. Check with the Oregon State Extension Service to see how often they need to be treated.
- Thin out the excess little fruits on pears and apples. If you do not thin them, you will have little fruits and they might become too heavy and break off whole branches.
- Spray to prevent fruit flies on cherries. Check with the Oregon Extension Service:

The Rainy Season Has Arrived There’s no doubt about it — the rainy season has begun! November is historically the wettest month of the year in Oregon, and your landscape will thank you for a little extra preparation. Here are some tips to keep your garden healthy, resilient, and habitat-friendly this season: General Maintenance Clean roof and gutters to prevent overflow and protect drainage systems from clogging. Compost or mulch fallen leaves instead of disposing of them — they’re valuable organic matter. Look for bare soil and cover exposed areas with organic mulch such as medium dark hemlock, arborist chips, or fallen leaves. Weed first, then mulch to prevent erosion and feed soil lif e. Mulch insulates plant roots, suppresses weeds, and supports beneficial organisms like earthworms and fungi. Some tender plants (Fuchsias, Dahlias, Cannas) benefit from an extra “blanket” of mulch to protect from frost. Remember: mulch in summer also conserves moisture and keeps roots cool. Check irrigation systems : Turn off the automatic controller. Turn off the water at the street or backflow prevention device. Drain the system if possible to prevent damage from freezing. Prune tall roses back by about one-third to prevent winter wind damage. Avoid hard pruning until they’re fully dormant later in the winter. Lawn Care (or Lawn Alternatives!) If moss is creeping in, it’s a sign of shade, poor drainage, or compacted soil. Before reaching for moss killer, consider reshaping or reducing your lawn. Converting shaded areas to native groundcovers or meadow plantings benefits pollinators and reduces mowing. If you maintain lawn areas, aerate, lime (50–80 lb per 1,000 sq ft), and fertilize with a slow-release winter blend to support healthy growth. Remove fallen leaves promptly. Wet leaves can smother grass, but when raked into planting beds, they become excellent free mulch that improves soil structure and provides habitat for overwintering insects. Store garden tools and equipment clean and dry: sharpen blades, oil metal surfaces, and disconnect hoses to prevent freeze damage. Planting & Seasonal Color Now is the best time to plant or transplant trees and shrubs — roots establish best in cool, moist soil. (Unless we are talking cacti and succulents, let's plant those in Spring!) Still time for spring bulbs! Get tulips, daffodils, crocus, and alliums in the ground before it freezes. Force Paperwhite Narcissus indoors for holiday blooms — they flower in about five weeks. Prune shrubs that bloomed in late summer or fall. Avoid pruning spring bloomers now, as you’d remove next year’s buds. Soil & Drainage Watch for water pooling during heavy rains. If you see soggy areas, consider adding rain gardens, French drains, or dry wells to improve infiltration. Native sedges, rushes, and moisture-loving ferns thrive in these areas and support native pollinators. Compost and leaf cover: Spread composted manure or leaf mulch over dormant garden beds to feed soil life and prevent compaction. Shrubs, Trees & Perennials Rhododendrons and Azaleas: If leaves are yellowing, fertilize lightly with an acid-loving plant food while soil is moist. Never lime these plants. If they’re already green, simply mulch with leaves — they prefer organic matter over extra fertilizer. Tender perennials like Dahlias or Cannas can be dug, stored, or mulched deeply for winter protection. Vegetable & Edible Gardens Garlic can still be planted for harvest next summer. Fruit trees: rake and remove diseased leaves to prevent fungal spread — replace with clean leaves or bark mulch. Rhubarb and asparagus beds: top with compost or composted manure. Cover vegetable beds with a 3–4-inch layer of leaves to prevent compaction and enrich soil for spring planting. Store potatoes around 40°F in a dark, cool space like a garage. Habitat & Wildlife Leave seed heads on native plants, ornamental grasses, echinacea, and rudbeckia to feed birds and shelter beneficial insects. Add bird habitat: Provide water, shelter, and native food sources through shrubs like snowberry, elderberry, and red-twig dogwood. Avoid using slug bait with metaldehyde — instead, hand-pick slugs or use iron phosphate-based alternatives safe for pets and wildlife. Consider planting Saffron Crocus (Crocus sativus) — a late-blooming crocus that supports pollinators and yields edible spice threads next fall. Houseplants: reduce fertilizing during low-light months; let them rest until spring.
On Saturday, September 27th, we held our fall plant sale at Thornhurst Garden—and what a day it was! The garden itself provided the perfect backdrop, with the changing leaves and late blooms showing off the season’s beauty. It was such a joy to see so many friendly faces—neighbors, friends, and new visitors alike—coming together to share their love of plants. Events like these remind us how much community is at the heart of gardening. The sale helped us find new homes for much of our overstock, and many folks walked away with treasures for their own gardens. Moist fall soil means these plants will settle in happily, making this truly the best season to get them in the ground. We also held a raffle, and we’re excited to announce that Sarah Reid was our winner! Congratulations, Sarah! Thank you to everyone who came out to support us, explore the gardens, and bring home plants. We’re already looking forward to the next time we can gather and celebrate together. (Here’s a look at some of the wonderful people who joined us that day!)
October might just be the best month of the year. Leaves turn gold and crimson, the first steady rains return to refresh thirsty plants, and the garden hums with renewed activity—birds darting through the branches and insects busy among the late blooms and fallen leaves. Soon, the season’s magic spills beyond the garden as little goblins and witches knock on our doors, candy bags in hand. For gardeners, fall is more than just a feast for the senses. Cooler days and moist soil create the perfect conditions for transplanting trees, shrubs, and perennials—plants settle in more easily now than in the heat of summer. (Unless we're talking Agaves, transplant those after the Spring rains) The softened ground also makes digging and dividing far less of a chore. Even challenging tasks like ivy removal become easier when the soil gives way beneath the roots. Autumn truly is a season of opportunity: a time to plant, to tidy (or not!), and to prepare the garden for the year ahead while savoring every bit of its fleeting beauty. The last week of October, but sometimes the first week in November, is the last time that we mow weekly. Be watching your lawn so that you can decide the best time for yourself. Occasionally, we will have a warm Winter, and a touch-up may be needed. Eco-lawns- Depending on the seed mix, you can leave these as is, allowing them to form more of a meadow look. This can help create more habitat for wildlife and insects. October is the first month when we have a higher probability of transplanting from moist, soft soil into a damp, soft new hole. All plants of course prefer to be dormant (asleep) when being transplanted. So, the coolness of October and the (hopefully) moist soil are perfect for the beginning of the transplanting and planting season. The best planting time typically extends from the rainy season until approximately the middle of March. Now is the best time to plant in Western Oregon! If you want Spring blooms, make a trip now to your local nursery and purchase Spring bulbs to plant in the ground! October/November are the traditional months for planting Spring bulbs. You can also plant fall bulbs now, such as Saffron Crocuses and Colchicums. The rain will bring out the dormant, sleepy slugs, so getting slug bait out in your beds now will hopefully thwart off a winter and spring invasion of new baby slugs! The Fall leaves will start to drop all over your yard. Remember to keep them off the lawn/grass areas and instead rake or blow them into your beds. The wet leaves will damage your lawn if left on, sometimes only in a day or two, but they can become great free compost/mulch for your planting beds. Lots of insects use this leaf litter as their habitat. This is a great way to invite more birds and wildlife into your garden as they forage through the leaves! I love watching them! This month, place mulch around potentially tender plants such as Cannas, Fuchsias, Dahlias and Calla Lilies. This will insulate them from frost or freezes. Get some bark mulch or chips and spread them 2” thick over any bare areas in your beds for the rainy season. This will prevent erosion and help choke out weed seeds from sprouting. If you are seriously into gardening, here are some more tips. Plant garlic bulbs now for harvesting next summer Pick any green tomatoes and bring them into the garage to ripen. Harvest Sunflower heads and bring them into the garage to dry. These are great for birds and human snacking. Sow native hardy annuals- you can sow these on any bare soil, or you can use gravel mulch and direct sow on that! Some great hardy annuals are California poppy (Eschscholzia californica), Red Maids (Calandrinia ciliata), Farewell-to-spring (Clarkia amoena) Gilia capitata, to name a few. Feel free to reach out to us if you have any questions about hardy annuals! A hardy annual is an annual plant you can sow in the Fall, and it will germinate, survive the Winter Months, and grow enough roots to sustain itself. Most of our natives will not require additional water the following year, and if they are happy, they will seed around and come up where they are thriving.
We look forward to seeing and catching up with so many of you! This is a great time to add new plants to your garden for discount prices as low as $5.00! Bring your friends! Please RSVP for the event at the link below: https://www.winterbloominc.com/contact
Garden Tips and Tricks for September September and October are my favorite months of the year. The air cools, the light shifts, and the season takes on that autumn magic that always makes me think of Halloween. Summer is winding down, but the garden is still alive with tasks that prepare it for the darker months ahead. Unlike spring’s dramatic storms and sudden frosts, fall eases in gently, carrying us toward the rainy season by late October. September Gardening Tasks: Ease off watering – Let plants harden off for winter, but check the soil and water if it’s dry. Keep weeding – Persistence now makes for an easier spring. Renovate or seed lawns – September and October are prime months while the air is cool and the soil is workable. Beware of fallen leaves on newly seeded areas. Slug baiting – Use traps or the beer-in-a-jar trick to keep them in check. Monitor areas and determine your threshold for damage. Slugs are also part of our habitat gardens. Trim back perennials – Clear away browned foliage to tidy beds before winter, or for habitat and sustainable gardening, leave perennials for mulch/habitat and forage for birds and insects. Planting and transplanting – September through March is ideal, with November the peak month. If you haven’t yet, begin planning which hardy annuals to seed in late October-November. Harvest – Gather winter squash, tomatoes, and potatoes while they’re ready. Winter vegetables – Early September is the last chance west of the Cascades for kale, Brussels sprouts, turnips, cabbage, and other winter favorites. Lawn fertilizer – This is the last month for summer fertilizer; switch to a fall/winter mix in November. Rhododendron cuttings – This is a good time to start new plants if desired. Prep compost piles – Stock them with fall leaves and garden trimmings for rich soil next year. Houseplants – Bring them indoors when nights turn too chilly.
May Tips for a Habitat-Friendly Garden Plant annuals (but wait on heat-lovers): May is a good time to plant annuals in containers and beds. Hold off on heat-loving crops like tomatoes and basil until nights are reliably warm and the soil has warmed—planting too early can stress or stunt them. Start mindful watering: If rainfall has been low, begin deep, infrequent watering (about once a week). This encourages strong root systems and conserves water. Avoid overhead watering in the evening to reduce fungal issues. Rethink the lawn: If you maintain a lawn, mow higher to reduce water needs and encourage deeper roots. Consider letting some areas go wild or replacing turf with native groundcovers to increase habitat value. Weed wisely: Focus on removing weeds that are going to seed first. Even five minutes of weeding helps! Leave less aggressive weeds in place if time is short—many provide cover or nectar for insects. Support natural pest control: Promote beneficial insects like ladybugs and lacewings by planting a variety of nectar-rich flowers. For aphids, try a spray of soapy water or simply hose them off. Avoid broad-spectrum pesticides, which harm pollinators and beneficial bugs. Slug and root weevil control: Use methods that target pests without harming other wildlife. Nematodes work well for root weevil larvae. For slugs, try beer traps, copper tape, or manual removal. Diatomaceous earth can be effective but may also harm beneficial insects—use sparingly. Leave the mulch: Let leaf litter and composted mulch remain under shrubs. It feeds the soil, retains moisture, and supports beneficial microbes. Fertilize only if plants show signs of stress, and choose fish emulsion or compost tea when needed. Plant for fall and for pollinators: Now’s a great time to plant perennials like chrysanthemums (for fall color) and native flowering plants that bloom through summer and into fall—providing nectar for pollinators and habitat for insects. Plan your veggie garden: By late May or early June, plant warm-season crops like tomatoes, peppers, cucumbers, squash, beans, pumpkins, and kale. Consider letting a few vegetables bolt (like dill and kale) to attract bees and butterflies. Watch for cabbage pests: Small holes in leaves may be flea beetles or cabbage worms. Use floating row covers, handpick pests, or apply BT sparingly. Companion planting with herbs like dill or nasturtiums can help deter pests naturally. Prune thoughtfully: After spring-blooming plants finish flowering, prune only if necessary. Leaving seed heads can provide food for birds and shelter for overwintering insects. Consider leaving trimmings in beds to decompose, except those trimmings of perennials with seed heads you don't want to spread. Avoid major trimming of trees, many birds are still nesting. Skip spraying trees unless necessary: If tent caterpillars are present and damaging fruit or shade trees, remove egg masses or nests manually. Spraying should be a last resort—consider how many caterpillars you can tolerate as part of a healthy ecosystem.
