Clematis Pruning Made Simple

These beautiful vines have a reputation for being hard to understand when it comes to pruning. This probably comes from the fact that there are so many different kinds of clematis, and different kinds are pruned differently.

Actually, when it comes to pruning, there are only three kinds of clematis: spring flowering, summer flowering, and those that flower in spring and again in summer. The first group flowers on wood formed the previous season, the second blooms on new wood formed since spring growth started, and the third group flowers on year-old wood in spring and on new wood in summer.

All first-year clematis should be pruned in February or March. Leave two sets of buds on each stem between the soil level and where you make your cut. In later years, follow the rules below.

Spring bloomers should be pruned to remove weak or dead stems just after flowering in May or June. Pruning later will result in fewer blooms the following spring. They need only be pruned lightly if space is limited. These include small-flowered Clematis montana varieties and the fragrant, evergreen Clematis armandii.

Clematis that bloom only in summer should be pruned in late February or March. Cut back all of last year’s growth to just above a good pair of buds about 10-12 inches from the ground. Over the years, a stump will form at that point from which new stems will grow. This will give you a plant with blooms that start near ground level and continue to the top of the plant. Clematis ‘Jackmanii’ is in this group, as are many hybrids such as ‘Ernest Markham’, ‘Gypsy Queen’, and ‘Hagley Hybrid’.

Those that bloom in both spring and summer should be pruned in late February or March. Remove any dead or weak stems, leaving an open, evenly spaced framework of strong growth. Cut back all other stems to a pair of healthy buds 1 to 4 feet above the ground. This group covers the rest of the large-flowered varieties and includes ‘Nelly Moser’, ‘General Sikorski’, ‘The President’, and ‘Henryi’.

If you don’t know which type you have, watch it for a year to see when it blooms and then prune accordingly. Always prune just above a joint where there are two healthy buds. If a plant has been neglected for many years, it can be rejuvenated by severely cutting back most of the old growth.

Remember that dormant vines often look dead, so trace the stem up to see if it supports new growth before cutting it off. The object in pruning clematis is to produce the greatest number of flowers on the shapeliest plant.

You can train clematis in many ways: on a trellis, on a fence or wall as a handsome tracery, twining up a tree, around a post or on an open framework for twining. Enjoy the “Queen of the Vines” in your garden.

• Last chance to spray peach and nectarine trees for peach leaf curl before the buds break open. Use copper sulfate wettable powder for the best results.

• Blueberries make delicious fruit on attractive plants that you can use in the orchard or the landscape. Choose varieties now.

Grapes for the Home Vineyard

An age-old fruit, grapes have been cultivated for over 6000 years and continue to grow in popularity today. Grown for fresh eating, juice, jelly or wine, grapes are widely recognized for their health benefits as well as for the production of fine wines.

Wine grape varieties represent only a small portion of the more than 600 kinds of grapes, and only about 60 varieties are suited to produce fine quality wine. The rest are considered table grapes, which are seeing a surge in popularity with today’s home gardeners.

Seedless table grapes are the most popular and Thompson Seedless and Flame Seedless make up the majority of table grapes sold in California. But both of these varieties require a considerable amount of heat to reach their finest quality. The Willits area just doesn’t get the amount of heat that the Central Valley does where these varieties grow to perfection. But there are many delicious grapes that are well suited to our climate.

There are two basic types of grapes, American and European. Our familiar table grapes and most wine grapes are derived from a single European species, Vitis vinifera. They have relatively thin skins that adhere closely to their flesh, and seeds that can be slipped out of the pulp quite easily.

American varieties, Vitis labrusca, are sometimes called slip-skin grapes, as their skins separate readily from the flesh; their seeds are tightly embedded in the pulp. The most familiar American variety is the Concord grape. Our area is suited to American grapes and to selected European varieties with lower heat requirements.

For delicious green grapes, try Interlaken Seedless, one of the finest American grapes. Its pale green berries are sweet and crisp and it is one of the first to ripen here. The clusters are medium sized and compact. The berries are good for eating fresh and excellent for raisins.

Himrod Seedless has golden yellow fruit that is sweet, juicy and delicious. It makes excellent raisins. Of the European grapes, Perlette is the first to ripen. Its pale green berries are very tender and juicy with a sweet to slightly tart flavor. Golden Muscat grapes produce huge clusters of golden delicious fruit. The oval berries are a beautiful golden color and are sweet, juicy, and flavorful. They ripen in the fall.

Suffolk Red is a seedless grape with round, firm, pink to red berries and a pleasing, spicy-sweet flavor. It makes a really delicious table grape.

The best known blue grapes are Concord and Concord Seedless, with blue-black grapes of a distinctive “foxy” flavor. They are used widely for grape juice and jelly. Black Monukka grapes have a deep, purplish-black skin and are very sweet with a rich flavor. They are crisp and delicious for fresh use and raisins, and do not need the high heat that Thompson does to get sweet.

Autumn Royal is crisp and sweet and makes a delicious snack for fall. With a purple-black skin and translucent yellow-green flesh, it has a pleasant, distinctive flavor. Give it a very hot location and the fruit will ripen toward the end of the season.

Grapes are so abundant and easy to grow, that no family orchard should be without them. Plant several varieties to enjoy their distinct flavors and a long harvest.

• Plant strawberries now for delicious strawberry shortcake this summer.

• Spray for peach leaf curl with copper sulfate. Peach and nectarine trees may suffer from this fungus disease without a protective spray.

• Pluots are a cross between plums and apricots. Their meaty fruit has a wonderful flavor. Bare root trees can be planted now.

• Flowering dogwoods and tulip magnolias can be planted now during the dormant season from balled & burlapped specimens.

• Clematis that bloomed last summer can be pruned now. Wait on spring-blooming varieties until after they bloom.

Early Spring Garden Chores

Bulbs sprouting, buds swelling and the first colors of flowers let us know that spring is just around the corner. Now is a good time to tidy up the garden to get ready for the early show.

Most roses need to be pruned now. Consult a good rose book for how to trim your type of rose since timing and methods vary with individual cultivars. Floribunda, hybrid tea, climbers, shrub and miniature roses are all a little different. Roses that bloom early, like Climbing Cecile Brunner, should not be pruned now. Wait until all of its rose blossoms have started to fade before pruning this rose.

Fruit trees, evergreens, many deciduous trees, raspberry canes and grapevines can all be pruned before new growth begins. Check with your local nursery for specifics or invest in a good pruning book.

It’s time to clean up the perennial beds. Start cutting back the plants that you left standing for winter interest. By now the first green swirls of new growth are appearing on ‘Autumn Joy’ sedum, so you can cut off the spent flowers. The birds have picked clean the seeds from the purple coneflowers, so those attractive seed heads can be snipped off, too. As soon as the first new leaves appear on your butterfly bush, you can prune them back hard to keep the plants compact.

Wait to prune lilacs and wisteria and other spring-blooming shrubs. If you prune them now, you’ll be pruning off the blossoms.

Now is when you should cut back your ornamental grasses. Hand pruners do a good job on smaller clumps, but hedge trimmers are handy for larger clumps. Hold or tie the old growth with twine and cut the grass 4-6 inches from the ground. Compost the old growth and look for new, green shoots to appear in a few weeks.

It’s time to start seeds of spring vegetables. Broccoli, cabbage, cauliflower, lettuce, chard and spinach can all be started now. Many interesting varieties are available on local seed racks. Start the seeds indoors with bottom heat and bright light then transplant them into 6-packs where they can grow for a month before it’s time to set them out in the garden.

Set out bare-root plants of strawberries, asparagus and onions. The strawberries and onions will produce this year, but it takes two years before you can harvest asparagus. After that, they will produce every spring for the next twenty years.

Add some colorful pansies and primroses to garden paths and containers. These beauties will bloom through April, when it will be time to plant summer flowers. You can also plant larkspur and snapdragons now for early color.

Enjoy the nice days of February by tackling some of these garden chores.
