June Gardening Tips

·       Compost should be watered during dry periods so that it remains active.

·       Prune only to retain the shape. Do not prune spring-flowering shrubs such as azaleas and rhododendrons. Do not prune trees.

·       Mid-August through September is a good time to transplant any shrubs that you've purchased with root balls wrapped in burlap. Make sure you get them in the ground two to three days after purchase. Do not fertilize until the second year, when the feeding roots have become established.

·       Lawns or bare spots reseeded with grass now will have a chance to get established before winter sets in. Water often and mulch with straw.

·       Two or three leaves should be left when cutting gladiolus, so that the bulbs can ripen.

·       Cut back the flower stalks of perennials that have finished blooming. Cut delphinium flower stalks to the ground, and a new, though smaller, flower stalk will develop. The flower will survive the coming cold days and even light frosts.

·       Lift, divide, and replant Japanese and Siberian irises soon after bloom. Transplant them to places where they will have "wet feet but dry knees."

·       If you notice a gap in your perennial bed between spring and fall blooms, visit as to see what we can recommend to fill in that space

·       The vegetable garden is likely to require daily harvesting now. Cucumbers, squash, tomatoes, eggplant, and peppers should be picked as soon as the fruits are ready. This not only captures the best flavor, but it also makes way for new fruits.

·       Maximum flavor of herbs for drying is achieved by cutting them just before their flowers open.

·       Make sure that potatoes are not escaping into the sunlight. Hill or mulch them if they are.

·       Remove dead pea vines, bolted lettuce, and other plants that have gone by and add them to the compost pile. If they show signs of disease, however, discard them in a trash bag.

·       Separate melons from the ground with a thin board to prevent decay or damage from wireworms.

·       Do not neglect your plants in hanging baskets; they dry out faster than those in the ground.

·       Dig up your potatoes once the vines have died and the tops turn brown.

·       Ripen tomatoes on the vine, not the windowsill; put fallen green tomatoes in a brown paper bag with an apple.

·       Fertilize roses (last time this year).

·       Keep weeding your garden so that the weeds do not compete with your plants for water and nutrients.

·       Japanese beetles? Handpick and drop in a jar of detergent and water or stop by for a remedy I have in stock.

·       Tomato hornworms? Handpick and drown in soapy water or snip in half. Control the smaller worms with B.t. (Bacillus thuringiensis), a biological control.

·       This is a great time to plant new perennials, shrubs, and trees, especially evergreens; they have a better chance to establish themselves during the milder fall months than those planted in the spring.

·       There's still time to plant fall crops of beans, beets, broccoli, carrots, Chinese cabbage, kale, lettuce, and peas.

·       If there are dry spells, remember to water your plants and shrubs thoroughly to prevent drought damage.

·       Remove any old plants that have stopped producing to help eliminate insects and diseases from your garden.

·       Dig up and divide daylilies that have finished blooming.

·       Remove any dead flowers from plants to encourage new growth.

·       During these warmer months, raise the mowing height to 2.5 to 3 inches.

·       Check the mulch around your plants; if there is little or no mulch, make sure to put a 3- to 4-inch layer to conserve moisture.

·       Be sure to regularly water your houseplants and potted plants. Use a water-soluble fertilizer so that the plants do not lose vital nutrients. Do not let houseplants dry out.

·     If you have any houseplants sitting directly in the window, make sure the light is filtered or the plant is moved to a site out of direct sunlight. The windowpane intensifies the heat, and you don't want to scorch your plants.

·     Fertilize your houseplants frequently to ensure vigorous growth.

·     Snip off the old flower clusters from roses to encourage them to bloom all summer.

·     You can sow a fall crop of bush beans now. Plant seeds two inches deep to protect them from the hot Sun. You can sow other vegetable seeds for an autumn yield, too, by planting them just a little deeper than you did in the spring. The best time to plant is after a rain shower.

·     Don't water your melons at the base of the stems. Doing so can cause rot. Build up a little earth around the stems to keep water away.

·     Once melon vines have set three or four fruits, remove any new blossoms. The remaining fruits will benefit from this, and you will still have plenty.

·     If your trees have any yellow or undersize foliage, start feeding them regularly. Be sure not to overfeed them.

·     Harvest summer squash when it's young and tender (8 inches).

·     As the weather warms up, do not neglect your watering. Water deeply in the morning and avoid light sprinklings. Water at the roots, not on the foliage.

·     Start herbs such as parsley, dill, and basil in pots for indoor use over the winter.

·     Harvest tomatoes, zucchini, beans, and other fruiting crops frequently to encourage production and avoid attracting pests.

·     Sow vegetable seeds for your fall garden: carrots, beets, turnips, collards, Chinese cabbage, snap beans, radish, kohlrabi, endive, kale, rutabagas, and summer squashes.

·     Set out broccoli, cabbage, and cauliflower transplants for your fall garden.

·     Lightly fertilize tomatoes and peppers. Don't overfertilize.

·     After broccoli head is harvested, the plant continues to grow side shoots.

·     Prevent weeds from seeding; this will mean fewer weeds next year. Pull weeds as they grow and use mulch in your flower beds to prevent them from sprouting.

·     When there is less than an inch of rain in a week, water extra. Water in early morning.

·     Mulching is an important job to keep up with in July. Organic mulches break down over time, so be sure to check the mulch around your plants. Keep a 3- to 4-inch layer of mulch around your plants to retain moisture. Also keep a thick layer of mulch around the roots of trees and shrubs.

·     If white crust develops in containers, it's salt buildup; remove and water heavily to flush out salts.

·     Remove tomato suckers to keep the energy focused on the fruit on main branches.

·     If your tomatoes have "blossom end rot," this means they are calcium deficient, so try using Tomato Tone by Espoma (I carry it here and I also have sprays to raise the calcium levels)

·     Lightly fertilize long-season plants, such as onions, tomatoes, and peppers, to help encourage growth.

·     Pinch back mint, oregano, and savory to promote bushier growth.

·     Newly planted trees and shrubs need two to three thorough soakings per week.

·     Finish pruning spring-flowering shrubs by mid-month.

·     Annuals and perennials can be planted at any time to fill in blank spaces in the garden.

·     Remove any dead flowers from your annuals and perennials to encourage new growth.

·     Garlic and onions are ready when their tops start to bend over. Remove their tops after they've dried for a couple weeks and store in a cool place.

·     During these warmer months, raise the mowing height to 2.5 to 3 inches. Water your new lawn with 1 inch of water per week to ensure healthy growth.

·     Feed your roses at mid-month to encourage more flowering.

·     Dig up and divide crowded spring-blooming bulbs whenever they are dormant.

It’s hot out there for newly planted trees and shrubs. These plants may be struggling to survive the heat and drought because their root systems haven’t had a chance to get established in the native soil yet. That’s why it’s important to pamper spring-planted trees and shrubs during the first year after planting. Most trees fail after the first year of planting because they were stressed and never recovered from transplant shock. Here are some ways to take the shock out of tree planting.

Keep them watered. Young trees need moist soil to survive the first summer. If you have sandy soil, the roots will dry out quickly and the leaves may shrivel and drop. If you have clay soil, the dry ground will rack, exposing roots and causing them to dry out. You should water your trees a few times a week and deeply. Add 5 to 10 gallons of water per tree each time.

Use a gator.  If you don’t want to be a slave to tree watering all summer, try this product. Tree gators are plastic-sleeved devices that wrap around trees. Fill them with water and they slowly release the water over time, keeping the soil around the rootball moist.

Mulch them. Keep the soil around the tree or shrub mulched with an organic mulch. This will help keep the soil moist, plus prevent weeds from growing. Be generous with your mulch ring size. Spread it outside the drip line of the plant. The feeder roots will be more likely to penetrate the native soil if there is no competition from other plants and the soil stays moist. Add a 2- to 3-inch-thick layer of mulch around each tree and don’t pile it up next to the trunk or the tree may suffer from crown rot.

Stake or no stake?  Staking usually isn’t recommended for newly planted trees. The gentle swaying from the wind helps the new roots get established. However, if you have a windy location, you may want to stake the tree for just the first year so it doesn’t blow over.

It’s always a shame that, just when your window box has reached its peak of fullness and color, autumn sneaks in and nips at the foliage and flowers, signaling it’s time to clean them out. Or is it? This season, try extending the life of your window boxes, so you can appreciate their beauty year-round, each time you glance out your winter windows.

As your lawn endures the trials of Job this Summer—drought, pestilence, and disease—you must hold to the hope that there is a lush, green turf on the other side of this summer. Has your spring turf been reduced to an arid, brown toasty color? If not, you might want to submit your water bills for federal disaster relief. Dry, scorching heat is the perfect scenario for crabgrass to flourish and bluegrass to perish. What’s needed, of course, is a good, deep penetrating rain. The large Japanese beetle population will mean a heavier than normal population of grubs. Knowledge is of course your best defense. Here are a couple of suggestions for reviving your lawn.

Not all insects are harmful to your garden; in fact, many are beneficial and are an important part of the ecosystem. Chemicals used to eliminate insects do not discriminate between the good bugs and the bad ones, so you can limit the damage done to beneficial insects and, at the same time, keep harmful chemicals out of the environment by practicing organic pest control.
