Rose Pruning
In Santa Barbara rose pruning season is generally between Christmas and Superbowl. Roses are a deciduous shrub. In our mild climate, we don’t often receive the cold required for real winter dormancy, so it’s especially important to clean them up for a good healthy start in the New Year. Pruning actually breaks dormancy.
We prune roses for health, shape, growth control, and to encourage new canes.
· Remove any dead, diseased or damaged wood.
· Check for sucker growth. Suckers are canes from below the bud union.
· Leave 3, 5 or more, young strong canes. Remove week spindly canes . Remove old gray ones. Best blooms come from new growth. Remove crossing canes, and canes that rub against each other.
· Cut back desired canes into an open vase shape. All pruning cuts should be made ¼ inch above and angled away from an outward facing bud.
· Light pruning is removal of about 1/3 of the height. Hard pruning is about ½. Your pruned rose will probably be 2 to 4 feet tall.
· Saw off any dead wood at the base of the rose if necessary.
· Lightly brush old peeling bark on crown with a brush to stimulate new canes,
· Remove all foliage. Clean up all debris. Apply dormant spray to plant and soil.
· Fertilize in March after foliage grows.
General guidelines:
Hybrid Teas: 3-5+ canes in a vase shape open in the center
Floribundas: 5-7 canes in a vase shape open in the center. Sometimes not pruned as hard as hybrid teas.
Shrub and groundcover: Usually have more “twiggy” growth habits.
Prune the same as a floribunda, leaving more lateral branches.
Climbers: need little pruning for the first few years. Prune to shape.
Leave laterals 2-3 , as this is where climbers bloom. Yes, you do need to strip all the leaves.
Don’t worry. Our roses will recover from any mistakes we may make.

Frost Tips
In the Santa Barbara area we have many microclimates. Some of these are susceptible to frost damage in cold winters. If you live in the bottom of a canyon you know how chilly it can get.
Do not fertilize permanent landscape plants except for lawn, cool season annuals, and vegetables after October 1. This allows plants to harden off. Tender new growth is more susceptible to frost damage.
Keep your plants well watered. Damp soil retains more heat than dry soil. Mulch to trap soil heat and protect roots.
If frost is in the forecast, there are precautions you can take. Group tender container plants under eaves, against the house, under covered patios or large trees. They may be covered with sheets, blankets or products like row cover and insulation cloth. If you use plastic, make sure you stake it up, so it does not touch plants. You can string large bulb Christmas lights to keep plants warm.
Many plants don’t mind cold weather. Most of our trees and shrubs will be fine. It’s the plants of tropical origins that are very unhappy. Examples include: Hibiscus, Bougainvillea, Impatiens, Mandevilla and Ficus If you have tender plants you may cover them the same as your containers above. Make sure you uncover plants before the sun hits them the next morning.
If you get frost damage the most important thing to remember is: Do not prune off damaged foliage until new growth appears in the spring and all danger of frost is past. In Santa Barbara this is usually late February. Frost damaged leaves and stems may not be attractive but they will protect the plant from subsequent frosts.
After an occasional hard frost it’s a good idea to hose the plants off before the sun hits them.
Most established woody plants survive Santa Barbara frosts with minor injury. If you live in an area that freezes most winters its best to avoid tropicals. Watch for clear, cloudless, winter nights with low humidity. A great place to check the forecast is: http://www.nws.noaa.gov/ or 805 9886610.

Fall Rose Care
One of the most asked questions for this time of year at the Nursery is, "what to do with the roses?" After the summer heat, fall's cool down can produce some of the years best blooms.
Do you feed? Do you prune? Should you continue to spray for insects and disease?
No, to all of the above: most experts let them rest. If you must, you may pick or dead head the flowers before Thanksgiving but that is about it until January. With the cooler temperatures, the roses feel like it is spring again. They love the cool nights and sunny days. You can still get a last great bloom for Thanksgiving.
But do not feed! You don't want to encourage new growth as we go into winter with shorter days and colder temperatures. The buds and flowers would be ruined by the moisture and dampness in our coastal air. You want them to slow down and rest. To conserve their energy for next springs big show.
By allowing the roses to "bloom out" and develop "rose hips", it sends a signal to the bush to slow down. It will stop putting out new growth and forces it into dormancy. It has been working all summer and needs some time off, just like us.
You can keep the bush clean from yellowing leaves if you must, but it is going to look a bit raggedy anyway. It's just that time of year. Very important, is to not forget the regular watering. Even though they are slowing down, their need for water goes on thru winter.
So now, for the most part, you can take some time off from the demanding summer rose care until January. At that time you will have to jump back into "rose maintenance", with the hard pruning and dormant spraying for insects and disease. But that is a whole other subject.
So until then, enjoy the rose season's last and possibly, “best blooms", of the year. And don't forget to check our website for the 2009 Bareroot rose list. It is never too late to find a new place to squeeze in a new rose.

| Trees for Planting in Lawns Many trees do not like to be planted in lawns. They perform best with deep infrequent water rather than the shallow frequent water we put on our lawns. We often see problems with lawn planted citrus in particular. Here is a list I've started. If you have any suggestions email me at nursery@lasumida.com. Planting a tree is a big commitment. It will probably outlive you. It's important to plant the right tree in the right place. My favorite website for choosing trees is http://selectree.calpoly.edu They have over 6000 photos of over 1000 trees. You can also search for trees by many attributes. Some of these include: climate zone, soil type, size, utilities, root damage, growth rate, disease and pest resistance, fire danger, flower color, etc. etc. etc. I always advise customers looking at trees to "do the research' and this website makes it easy. Take care, D Arbutus unedo Strawberry Tree |

With fall comes the transition of the summer garden into winter color. Hard to think about sometimes when the days are still nice and warm. This can be a confusing timing issue. After the warm August and September days, while most of the garden is still showing color, it can be a little tired and overgrown. Even the garden at the front of the nursery shows the "end of summer" stress.
So this is the time to re-look at the garden. See what needs to be cut back or taken out. I know that it can be hard to prune back plants when they are still trying to perform, but it is better to do the trimming now, so they have time to re-grow before the cooler winter nights slow them down and they don't have time to put out new growth. You can also take this time to decide on what needs to be taken out or relocated. We all have planted and then realized that it was the wrong choice or didn't perform the way we may have envisioned.
My gardens are never static. I am always learning and changing. Plants I thought would look good and fit nicely into my landscape, end up getting to big, out of control, or just don't look like what I wanted. So I usually dig it up, pull it out or move it and swear that I am going to simplify my garden and make my life easier next year.
Fall is a great time to think about changing your garden. It is still warm enough for new plantings to root in. And there is still a good selection of perennials available at the nursery. Also the colorful, winter annuals and cool season veggies have arrived.

Don't be afraid to make changes. That is what keeps the garden interesting.I love to see the different combinations our customers put together. Keep on learning, Judi
