| Speaking of Grasses... |
Lawns are one thing, but what about ornamental grasses? They provide a nice variation in the garden and are very tolerant of summer heat. Another benefit is that they bloom in the late summer and fall when fewer perennials are adding color in your garden. Ornamental grasses come in many sizes and varieties. They can be dramatic, stately, or soft and feathery, depending on which you plant. Remember that the flowering of an ornamental grass looks like mature grain rather than a typical perennial flower. We have all kinds of ornamental grasses this summer, in 3, 5, 7 and even 10 gallon pots. You'll be able to establish them quickly and see their dramatic beauty this season with plants this large. Come see what's in stock! Below is a sampling. Maiden Grass has beautiful draping form and a delicate flowering head in late summer. It comes in many heights depending on which variety you select. Some are also variegated. We carry 'Morning Light', 'Gracillimus', 'Flame Grass,' 'Zebra Grass', and 'Porcupine' and other varieties. Fountain Grass and Feather Reed Grass are both popular summer flowering grasses that range in height from 2 to 6 feet. Each has a different growing and flowering habit. Carex likes wet conditions and comes in many varieties. Carex grayi is especially interesting with a spikey flower head. Japanese Forest Grass or Hakonechloa is best known for 'Aureola' which has yellow and green foliage. It has a pleasing draping habit and combines well with rocks in the border. Northern Sea Oats looks like wheat, with its seed heads shimmering in the wind. If you want blue, try Blue Oat Grass, LIttle Blue Stem or Elijah Blue Fescue in your border! And finally if you want something truly dramatic and 12 feet tall, we have hardy Pampas Grass. |
| Tomato Time | Perhaps by now you are already eating the first of those yummy vine ripened tomatoes from you own garden. Perhaps you are still anticipating the first to ripen. Or perhaps, you are seeing some evidence of problems to your crop. Here's help! Blossom drop: In extremely hot weather your plants can drop their blossoms before they begin to form fruit. If you see this happening, be patient and wait for cooler weather. The plants will set new blossoms. Blossom end rot: The tomato has a leathery, dark spot on the bottom. It eventually rots. Eeew. Blossom end rot is usually caused by wild fluctuations between wet and dry weather. Keep your tomatoes evenly moist during dry spells. Remember to water deeply at the base, not with an overhead sprinkler, which can cause other problems. Wilt: First you see leaves turning yellow. Then you notice that a stem is wilted. Pretty soon the whole plant wilts. Your tomato dies. Have a funeral, clear away the plant and all plant debris and plan for next year. Your tomato died of a fungal condition that grows in the soil and (by the way) remains in the soil for some years. Make plans to put your tomatoes in another location next year and but plants or seeds that are VFN resistant. Lotsa leaves, no tomatoes: your tomato is rich in nitrogen and poor in phosphorus. Use a fertilizer with more phosphorus, or, in simpler terms, one with a high middle number (10-20-10). Cracked fruit: (Yes, tomatoes are a fruit!) Tomatoes love hot sun and will grow fast in hot sunny weather. But if they don't get even moisture, the fruits may crack (ouch!). Again, water deeply at the base to keep the soil evenly moist. This lessens the likelihood of cracked fruit. Leaf spot: Your tomato plant has irregular spots on the leaves and some leaves turn yellow. Leaf spot is another fungal condition. If you observe this problem be extra careful not to work around your tomatoes when they are wet. Water from the bottom and keep picking your ripe fruit. At the end of the season, don't add the debris from this plant to your compost as it will spread the fungus that causes leaf spot. |

| Featured Plant: Daylily | |
Photo courtesy of northscaping.come.  | Our featured plant this time is the daylily, so named because each blossom lasts for only one day. Daylilies are prolific bloomers, however, and each plant produces many blooms this time of year. Some have also been bred to rebloom throughout the season. Daylilies are easy to care for and provide clumps of color in the midsummer garden if planted in a group. They like full sun. Traditionally daylilies were orange and yellow, and many gardens use the popular golden yellow Stella D'Oro or Happy Returns for their heartiness and shorter height. But daylilies come in many colors now - red, pink and white to lavender, purple and even black. We carry many varieties, including the red Chicago Apache, Fairy Tale Pink, Strawberry Candy, Grape Magic and more. |
| Hot Weather Lawn Care | |
The hot weather of midsummer is a challenge for lawn care. So far this summer, during most hot periods we have had adequate rainfall in the form of periodic thunderstorms. But it can also get very dry in late July and August. Here are some tips on how to care for your lawn without seeing your water bill head to the stratosphere. The first thing to know is that our lawns are, in most cases, a mix of cool season grasses. These grasses are adapted to the cooler temperatures we have in the northern states. They grow best at 60 to 75 degrees Fahrenheit. That's why we see our lawns getting green early in spring and remaining green well into the fall. However, we also may have dry, brown looking lawns in the heat of midsummer. This is because cool season grasses, while formulated to have maximum drought tolerance, will go dormant in hot weather if they are not well watered. This is actually a benefit. It means that you have a choice about how to care for your lawn in the hottest part of the season. You can stop watering and, in all but the most severe drought conditions, your lawn will become dormant but will remain viable and will spring back to life when the temperatures moderate. If you wish, you can also water your cool season turf in midsummer and keep it active and alive. If you make this choice the grass will need a deep watering (about 20 minutes) twice a week or so if it does not rain approximately an inch per week. Watering should be done in the coolest part of the day, preferably morning, so as little water as possible is lost to evaporation. Also, morning watering reduces the incidence of turf diseases stimulated by wet grass during the night time hours. There is one very important thing to know about these choices: It's one or the other. You cannot successfully switch between them during the same season. If you decide to let your lawn become dormant, you will not be able to revive it successfully in the middle of the hot weather. If you decide to water when the heat strikes, you'll need to keep on watering throughout the season when it does not rain adequately. Many people these days choose to allow their lawns to become dormant. This is the "greener" approach when we think about conservation, even though your lawn is brown! |
| Summer Blooming Shrubs |
Shrubs that bloom in mid-summer can also add interest and color in the garden this time of year, believe it or not! We most often think of flowering shrubs in May, but these four beauties are best in July and even August.
Photo courtesy of Northscaping.com | Summersweet Clethra (also known as Sweet Pepperbush) is one of the last plants to emerge in the spring, but blooms in July with stunning flower spikes in white ('Hummingbird' and 'Sixteen Candles') and dark pink ('Ruby Spice'). Its flowers are intensely sweet smelling, and its size is moderate - not much more than 5 feet tall and 3 feet wide in our area. For these reasons, this is a nice shrub to plant by a doorway. Hummingbirds and butterflies love this plant when it is blooming. Give it plenty of moisture and organic material to offset our heavily clay soil. Oakleaf Hydrangea is a summer beauty that gets better and better as the growing season progresses. Huge long flower heads bloom white in midsummer and become pink as they age. In the fall, the huge oak-like leaves of this shrub turn dark red before they fall. Once the branches are bare, oakleaf hydrangea displays its interesting peeling bark. Select a sheltered, partially shady spot and mulch around the base. Bottlebrush Buckeye is a stately and very impressive shrub for the woodland setting. Its large dark green leaves and impressive flower spikes are show stoppers in late summer. The flowers, which are white, attract bees and butterflies and last up to a month. Bottlebrush buckeye gets quite large - up to 12 feet high and 15 feet wide at maturity - so give it plenty of space and it will reward you well. Butterfly Bush is popular in our area and comes in many varieties. The 10-inch panicle flowers are stunning in themselves. The are white, lavender, pink, yellow or deep royal purple. As its name suggests, this is a butterfly magnet in the garden! Its flowers are long lasting, even when cut for indoor use. Butterfly bush keeps blooming to frost if you plant in full sun and deadhead spent blossoms. While butterfly bush may grow to 10 feet tall, its lovely arching shape gives it a delicate look. In our area, butterfly bush should be cut back to within 4" of the ground each spring. It will regrow from the ground up, since the old wood dies in our cold winters. |
| Summer Pests: Innocent until Proven Guilty | |
It's time to consider the pests you are seeing in the garden. Before we talk of individual suspects, however, a word of caution. Garden pests are not created equal. All insects should be considered innocent until proven guilty!
Insects may be pests and they may not. It all depends on the balance of nature in your garden, the insects you have, and the damage you are observing. If your soil is healthy and you have not used many chemicals, the garden will achieve its own balance so that one particular kind of garden pest does not "take over" and cause excessive damage. So, when you can prove one type of insect guilty of causing harm, the cautious approach is to use the least harmful method possible. This approach helps to maintain the natural balance in your garden. Okay, now on to the accused! At this time of year, you may see mature Japanese beetles on your roses, tomatoes, beans or other plants. This pest is easily identified by its iridescent copper body and green thorax. The beetle damages plants by skeletonizing the foliage, that is, consuming only the leaf material between the veins. Japanese beetles can be controlled with soapy water spray if you have only a small number.If you have a large number of them, we have sprays to eradicate them. However it's best to begin a cycle of treating your lawn throughout the season to kill the larvae of these bugs before they mature. We can help you determine the right product for your infestation. Slugs can cause a great deal of damage if they are present in large numbers. You will see them in wet areas under plant debris and you will likely see their damage most readily on hostas that are not slug resistant. If you find these pests we have organic and non-organic products to eliminate them and there are also a number of home remedies to control them. Eggshells spread around your plants will damage their bodies and kill them. A little bit of dry gravel will dry them out. Copper pennies under your hostas also work to deter them. Fresh beer placed in plastic carton lids around the garden will collect slugs. Weeding and clearing away debris will ruin their habitat. However, don't heed the bad advice, readily available online, to avoid all composting in your garden to control slugs. Compost is very good for your soil and shouldn't be elimnated just to control slugs. Because it was very wet in June, you may also see earwigs in the garden. They are recognized easily by their pincers. The bug is dark reddish brown and about ½ inch in length. Earwigs live in wet areas and eat dead bugs and decomposing plant material. They can damage plant material. If you have a large number and see evidence of damage to your vegetable crops, you may want to treat for them. However, as with all insects in the garden, it's important to evaluate whether their presence is causing damage. Earwigs, since we are talking about them, also have a beneficial role in the landscape and have been shown to be important predators of aphids! |
