June has arrived in the PNW, and our gardens are starting to produce a thrilling abundance of color, fruit, and veggies. As we begin our roll into summer, the days are warmer and longer. Summer solstice is marked as the midsummer point, and is measured by the earth’s tilt towards the sun, which results in the longest period of daylight of the year. This year's summer solstice is on June 20th, so now is the time to begin preparing your garden for that long-awaited garden party! 

June is also pollinator month.Encouraging natural pollinators like bees, butterflies, and hummingbirds will help your garden thrive. These insects are important components of the ecosystem because they are necessary for plant reproduction.We put together a guide for encouraging natural pollinators in your garden, and you can read ithere.


Watering should be a priority this month, as the days get warmer and soil tends to dry out quicker. It’s easy to overwater in June, since the PNW can have inconsistent weather this time of year. Make sure you aren’t over watering by checking the soil frequently. Dig down around 5 inches to see if there is enough moisture. Test sprinklers to confirm they are covering areas appropriately and evenly through the summer. Consider using organic mulches to prevent rapid water evaporation.

June is a good time to harvest and re-bed worm bins. EarthWorms can create rich compost for your garden by recycling the organic waste from your household. If you don’t have one already, consider constructing a worm bin to compost kitchen scraps. The worms will munch on the scraps and leave castings behind, which makes excellent compost. Make sure to provide your worms with clean, moist bedding like leaves or newspaper strips to keep any lingering odor from entering your kitchen. You will also need to regularly feed your worms with vegetarian, organic waste like vegetable peelings, coffee grounds, grain, and egg shells (make sure you don’t give them any egg...they eat a plant-based diet for the most part).

Continue to watch for signs of pests and treat with natural, organic methods. You may see signs of butterfly larvae in the form of droppings and holes in leaves or on leaf edges. You can treat by crushing eggs, hand removing caterpillars, or using a floating row cover. It is important to note, however, that it's wise to learn to spot the difference between beneficial insects and harmful ones. Read our guide for encouragingnatural pollinators here.

Edible Gardening:

Many of your veggies will be ready to harvest this month. Look for artichokes to be ready, along with radishes, leafy greens like cabbage and spinach, and soft fruits like strawberries. 

Some tomato varieties will begin to ripen and provide fruit this month. Keep your plants healthy by providing them with plenty of sun and water. Tomatoes require at least 8 hours of continuous sun a day, so finding a bright enough spot will be your main challenge. You will also need to fertilize often with low nitrogen, organic fertilizer likeEB Stone Tomato & Vegetable Food. Keep your plants pruned to 2-4 main stems, which will promote faster ripening. It is also suggested that you use trellises and cages to allow for proper air-circulation around your plants, which will decrease the risk of fungus and disease. 

Now is the time to plant pumpkins and squash for fall and winter harvest. We have many rare and unusual varieties to choose from! Many autumn and winter crops should be sowed this month. You can also extend your harvest into July and August by sowing chives, garlic, cucumbers, lettuce and snap beans this month.

Outside Plants and Flowers:

Now is a good time to plant flowers for color in early autumn. Sunflowers are always a favorite in the PNW, and seeds sowed now will provide beautiful color in the fall.

Consider replacing your pansies with some zinnias, dahlias, lantana, portulaca, salvias, echinacea (cone flower), and gaura. Pick heat-loving plants to provide color through the heat of summer.

Roses are a PNW favorite, and are coming into bloom this month. Watch for signs of disease and pests, water regularly, and make sure you are feeding them withEB Stone Rose & Flower Food. We love theDavid Austin variety of roses because of their amazing scent. If you are looking for more information on growing roses, you should check outthis video created by the folks over at David Austin, which provides some excellent tips for selecting and caring for your roses. 

Trees and Shrubs:

In May, we suggested you trim azaleas and rhodies as they finish flowering. If you haven’t already done so, this should be done as soon as possible to allow new bud growth to form for the next season.

Watch your fruit trees this month for signs of pests. As the temperatures warm, cherry fruit flies, codling moths, and apple worms may begin to damage your crop. Treat with traps orbeneficial insectsthat like to feed on these pests.

One of the best things about January gardens is that with most things paired back, you have a chance to notice and appreciate what might not normally stand out. For example, a mossy rock might shine with new life or a favorite tree that you usually admire for the leaves might stun you with its vibrant bark.

December is a great time to clean up the garden. This month also gives you a chance to look at the “bones” of your garden while leaves are off the deciduous trees to plan for next spring.
