Scale Insects Or Stem Canker

Sorry, but its hard to say for certain from your photo. This could be scale insects (like brown soft scale), or it could be a stem canker that has oozed sap. Looks like a scale more than canker ooze, but its hard to see from the photo if the stem underneath this "bump" is damaged, like with a canker. You can determine which it is by pulling one of the bumps off. If its sticky, like sap, then its a canker. If the bottom of the bump, when turned over, appears to have insect like characteristics (or tiny orange/brown eggs and/or little tiny crawling things) then you'll know it a scale insect. We've included a link about scales for your reference in getting them under control. For info on canker diseases you can search on-line by referencing the type of fruit tree and the word 'canker' (for example: canker diseases of stone fruits). We recommend looking for reliable info from college extension sites that end .edu

Weeping Mulberry

This appears to be a weeping mulberry. There are several species, red, white, and black mulberry. Some bear fruit. The fruit resembles miniature blackberries. Needs full sun and regular to ample water. Mulberries can get quite tall and aggressive. Prune back after the berries have been harvested to control its size.

Glossy, deep-green summer foliage cascading from its ground-dusting stems is the most attractive feature of the weeping mulberry (Morus alba). The two main types of weeping mulberry are the cultivars "Pendula" and "Chaparral," both commonly known as white mulberry for their greenish-white but inconspicuous spring blossoms. "Pendula" bears edible fruit; "Chaparral" bears no fruit but is needed for pollination. Weeping mulberry is hardy in U.S. Department of Agriculture plant hardiness zones 4 through 8. Unless you are growing this mulberry to feed silkworms, the last thing you want are creatures eating your mulberry leaves. Don’t panic. Controlling these pests is relatively easy.

Wollemi Pine

Your photo resembles a Wollemi pine, but we think it might more likely to belong to the Araucaria genus because as you probably know, the Wollemi was just discovered in 1994 in the Blue Mountains in New South Wales in 1994. Cultivated plants became available to botanical gardens in 2006. However it would be very exciting to find out that it is a Wollemi pine. Suggest you contact WollemiPine.com - the official home of the Wollemi Pine ...
www.wollemipine.com/ to see if they can confirm its identity for you. Here is some additional information for you: The Lost Valley of the Wollemi Pine - Scientific American
blogs.scientificamerican.com/.../the-lost-vall... If you do find out its identity, please let us know as this would be so exciting to know that a relatively mature Wollemi is growing in Nice!
We love the fact that a plant long thought to be extinct was discovered growing not to long a distance from Sydney, Australia.

Problems With Crabapple

From a photo alone it's impossible to know why this tree is losing leaves. Some general reasons that trees have leaf-drop or die back include:
1. Drought stress. A plant that hasn't gotten enough water will drop leaves in an attempt to save its life as leaves lose moisture through their pores.
2. Fungal disease. Apples are prone to a number of fungal diseases - these usually cause leaves to become spotted or yellow before they fall. Look at the remaining leaves carefully to see if you see spots or yellowing. Some trees are more prone to fungal problems than others.
3. Broken stems or trunk injury. A plant that's had stems broken, or the bark on the trunk cut or chewed will lose leaves and have dieback.
4. Canker - this is a disease some fruit trees get that causes sunken areas on the trunk that inhibit water flow up to the branches. You see branch dieback but the problem is really on the trunk - look for areas that look sunken and "water soaked" or are weeping sap.

Monterey Pine

Widely cultivated in California landscapes for its fast-growing habit and picturesque, deep-green appearance, Monterey pine is native to three locations along the California Coast (Ano Nuevo, Monterey Peninsula, and Cambria) and two islands off Baja California (Guadalupe and Cedros).
Monterey pine cones remain closed until the heat of fires or exceptionally warm weather cause them to open and discharge their seeds. Seedlings developing in areas newly cleared by fire gain the advantages of reduced competition for water and light, and ash-enriched soils. This habit allows the species to survive infrequent natural fires.
Despite its limited native habitat, it is one of the most widely planted trees in the world. In New Zealand, Australia, and Chile, it is the predominant commercial forestry species. Specimens grow exceptionally fast and straight in areas of year-round rainfall, whereas trees in California develop gnarled trunks and domed crowns.

Weeping Cedar Problems

First, let's say it doesn't look good. Was there any sort of warranty on the tree? We suggest you contact the seller.
That said... there are several species that share the common name Weeping Cedar. Which cedar is it? I can't tell from the photo, but perhaps there was a label on the tree? Some cedars are only hardy to zone 6, and you live in zone 5. The abrupt cold late last fall had damaged many plants.*
Your tree's problems are environmental, not caused by insects or disease. Since your tree is dying from the ground up, this is most likely root-related--either how it was planted or a water issue. Are you watering? Even though the sprinkler is turned off, all plants need damp soil during the winter, and especially evergreens. Irrigate on warm days (such as today) as needed. Too much water is as bad as too little, as roots also need air. There isn't room here for a treatise on tree planting, but check out http://www.ext.colostate.edu/mg/gardennotes/636.html and http://www.ext.colostate.edu/mg/Gardennotes/633.html.

Sodium Toxicity

This is exhibiting classic symptoms of Sodium toxicity. It could be caused by inadequate drainage, overfertilizing, or underwatering. There also could be excessive amounts of sodium in the water that you use to irrigate the tree. The tree looks like it might be salvageable. Our advice would be to invest in a larger container with drainage holes and brand new potting soil and replant. Relocate in full sun. You could also find a nice well drained spot in full sun in your yard and plant it directly in the ground if you wanted. Trim back the tree by 1/3 (if there is still green when you scratch the bark, that is a good sign). Water it in well but give it time in between waterings. It doesn't want to be too wet. Once it seems to have settled and starts putting out some new leaves, consider investing in a fertilizer specifically formulated for citrus that also contains micronutrients. Follow the directions on the label. Don't be too heavy handed in the beginning. More is not better this case.

Excelsa Western Red Cedar

Excelsa stays smaller but still retains the relaxed appearance of the giant Western Red Cedar.
n addition to being great for screening, some of these trees make excellent hedges. If you are tired of using broadleaf evergreens for your 5-15’ sheared hedges, try some of the conifers we just talked about. I would not recommend the Calocedrus decurrens or Chamaecyparis nootkatensis ‘Viridis’ but the others make excellent sheared hedges. For a very formal look, I recommend trimming 3 times during the growing season. For a formal but softer appearance, cut it once in the spring and let it flush; this also makes it easier to design around. Using these conifers allows you to start off big without the availability and transplant problems of broadleaf plants, like English Laurel, that are commonly used as hedges.
Whether using these trees for screens or hedges, they can add beauty and privacy to your next project. Try some of the lesser-known varieties to make your landscape really stand out.

Italian Prune

The Italian plum tree (Prunus domestica) produces a versatile fruit that can be canned, frozen or made into jellies and preserves. It is especially good for drying. The Italian plum or prune tree, also called "Fellenberg," grows to 15 to 20 feet high with a slightly larger spread. Because they are late bloomers and have a long growing season, Italian plum trees do best when planted in areas with a later frost date. They also respond well in areas with cold, wet springs. The pink or white blossoms appear in mid-spring.
Fruit
The Italian plum tree bears sweet purplish-black fruit of medium size. The flesh of the fruit is yellow-greenish. You can expect the tree to begin setting fruit three to five years after planting. It will reach full production at about 10 years of age, and you can expect it to provide fruit until the age of 15 to 20 years. Each tree will produce up to 3 to 5 bushels per year.

Scale Insects Or Stem Canker

Sorry, but its hard to say for certain from your photo. This could be scale insects (the dots and darkening), or it could be a stem canker if it goes all the way around. Looks like a scale more than canker ooze, but its hard to see from the photo if the stem underneath this "bump" is damaged, like with a canker. You can determine which it is by pulling one of the bumps off. If its sticky, like sap, then its a canker.
