June in the Garden-What to Do?

I didn’t get everything done in May that I had on my to-do list. Who ever does? Anyone who tends a garden knows how fast plants grow with the longer, warmer days and nights. So this month I continue to work on my own garden tasks as well as help others renovate their gardens to look great, support native pollinators, wildlife and habitat.

If you battle dandelions and don’t want to use chemical weed killers around pets and children, get out the white vinegar from the cupboard. On a hot sunny day spray straight white vinegar directly on the weed. This method will kill whatever it touches so direct the spray carefully. If the dandelion is in the lawn, wait a week, pour some water on the dead spot to dilute any lasting effects of the vinegar. Then poke a bunch a holes and drop in some grass seed. Sprinkle a bit of fertilizer where the seed is planted and keep the area moist. In three weeks you won’t remember where the dead spot was and the dandelion will be long gone.

Many plants, both vegetable and ornamental, are bothered by aphids and other sucking insects as well as foliage and flower eating bugs. From cucumber beetles, flea beetles, stink bugs, weevils, curculios to borers, the list of trouble makers is endless. To help deter them mix up some pepper spray in your kitchen.
1 tablespoon hot pepper sauce or 1 teaspoon cayenne pepper
6 cloves garlic, crushed
1 quart warm tap water
Let stand I hour, strain and spray plants either in the morning or evening.

Pink rhododendron.

When the last flowers of your rhododendron, azalea, camellia, weigela and spirea have finished it’s time to prune them. If you prune too many months after flowering your risk removing the flower buds forming for next year. Basically it’s best to prune lightly each year to shape plants that have become too leggy. The rules apply to most plants. Prune to the next whorl or set of leaves. To increase rhododendron bloom next year, break off any faded flower trusses just above the growth buds being careful not to damage the new buds.

Apply the second fertilizer application for the year to your citrus and fruit trees. The final one for the season should be immediately after harvest. Apply the fertilizer to the soil around the drip line of the tree where feeder roots are located and scratch into the surface. Water in well. As with all fertilizers, make sure the trees are moist before you fertilize. Young trees in their first, second or third growing season should receive half the rate of established trees.

Another garden to-do this month includes summer pruning of wisteria. To increase flowering next spring and keep these vines under control cut new growth back to within 6″ of the main branch. If you want to extend the height or length of the vine, select some of the new streamer-like stems and tie them to a support in the direction you wish to train the plant.

Another maintenance tip is to shear spring blooming perennials to keep them full and compact. Candytuft, phlox subulata, aubrieta and other low growing perennials benefit if you cut off spent bloom and an inch or two of growth. Other perennials and shrubs that benefit from the same treatment to keep them compact are erysimum, lavender and Pink breath of heaven.

Vines- What, Where and How

My office window looks out on a gingko tree. Hanging from its low branches two bird feeders are visited throughout the day by many songbirds. As an added bonus a climbing Zepherine Drouhin rose grows up into the branches and has just started to bloom with vivid, dark pink flowers. They look like ornaments hanging from the tree. This spot wouldn’t be right for a trellis so if it weren’t for the help of the gingko I wouldn’t be able to enjoy my beautiful rose. In your own garden think about trees, shrubs and even sturdy vines as support for other vines.

Creating an outdoor room with vines can make your yard feel cozy. They readily provide the walls to enclose a space. Views from one part of the garden may be partially open, framed by vines or blocked entirely. Shrubs can also be used to create garden rooms but vines form a thin living wall that is quickly established. Creating boundaries with vines also adds vertical design elements to an otherwise flat landscape. By adding walls and a ceiling to your garden, you’ll be able to enjoy another dimension in addition to more color and fragrance too.

many trees. From Lady Banks rose to clematis to blood-red trumpet vine to a spectacular double white pandora vine his trees do double duty in his garden.

For a vine with long lasting interest, try growing an orange trumpet creeper up into a tree. It blooms from midsummer to early autumn and hummingbirds love it. It can tolerate wet or dry conditions, sun or shade and is generally pest free.

Plant vines for fragrance in your garden. Let them scramble up a tree or through the branches of a shrub. Evergreen clematis bloom with showy white fragrant flowers clusters above shiny dark green leaves in spring. Clematis montana

is covered with vanilla scented pink flowers in spring also. Carolina jessamine’s fragrant yellow flower clusters appear in masses from late winter into spring.

Another way to double your pleasure with vines is to let the thick stems of a mature, vigorous vine such as grape, wisteria, passionflower or a large climbing rose like Lady Banks serve as a framework for a more delicate stemmed vine like clematis or Goldflame honeysuckle.

Or you can enjoy the classic combination of a flowering clematis like purple Jackmanii intertwined with a white Iceberg rambling rose for another great look. Other vines that are beautiful and easy to grow are our native honeysuckle, lonicera hispidula with its translucent red berries in the fall. Violet trumpet vine, white potato vine, hardenbergia and Chilean jasmine are also good choices.

Growing vines is easy if you follow a few guidelines. To encourage bushy growth on young vines, pinch out the stems terminal bud. If you want just a few vertical stems, though, don’t pinch the ends but instead remove all but one or two long stems at the base.

Often when I’m called out to take a look at a vine that has gotten out of control the only advice I can give is to cut the entire vine to the ground in late winter or early spring and start training it all over again. You can avoid this drastic measure by pruning periodically to keep your vine in bounds. Just before new growth begins, cut out unwanted or dead growth. If you can’t tell what to remove, cut the vine’s length by half and remove the dead stems later. On vines like hardenbergia or Carolina jessamine that bloom in late winter, wait to prune until after they have finished flowering.

Many vines require only deep but infrequent waterings. If you are interested in planting a new vine to provide color and fragrance in your garden there are lots of good suggestions on Scotts Valley Water Districts’ web site. www.svwd.org

Some to consider from their list of 800 low water use plants are bougainvillea, trumpet creeper, Carolina jessamine, primrose jasmine, cat’s claw yellow trumpet vine and purple leaf grape. Also on the website is a search function in the Water-Smart Gardening section for vines and other plants for particular situations such as shade, erosion, natives or low maintenance. It’s a valuable resource right at your fingertips.
