Rust On Plum Leaves

It appears that your tree has a rust fungus on its leaves. Most likely Plum Rust. Symptoms are yellow spots on leaves caused by pustules of brown spores on lower leaf surfaces. The underside of the leaves will show stronger symptoms than the top. Infected leaves develop a yellowish cast; leaf shedding may be severe. The condition becomes increasingly prevalent toward the end of summer. Sanitation is the only practical control after the disease has arrived. We would recommend taking a sample in a zipped plastic bag to your local garden center or Cooperative Extension office for a more positive ID and ideas on how to solve your situation.

Rose

Your cut flower is likely a hybrid tea florist rose. Because there are over150 wild species of shrubs and climbers native to Asia, Europe, North Africa and North America, plus thousands of different garden forms of varying growth and flower types divided into two broad categories Old Garden Roses and Modern Roses, we cannot identify yours specifically. Suggest you show a few clippings to a local garden center that specializes in roses or botanic garden to see if a horticulturist can identify more specifically.
You can also visit online websites such as www.helpmefindroses.com or your local rose
society. However all rose plants appreciate full sun, regular water and feed with a slow release or organic fertilizer formulated for roses.

Diffenbachia

There are dozens of cultivars of diffenbachia, and we have no way to tell which one you have.

Dieffenbachias have been decorating homes and offices for decades. These showy houseplants are prized for their vividly variegated foliage and large bushy growth habits. Some varieties grow up to several feet tall. The large pointed leaves grow from a central stem, or cane. As the plant ages it will lose its lower leaves, giving it a palm like look. You have a green variety

It gets the nicknames “Dumb Cane” and “Mother in Law Plant” as a result of the effects of the milky sap it contains. If ingested it causes a burning sensation in the mouth, swells the tongue, and paralyzes the vocal cords, literally taking one’s voice away.

Pests Of Basil

It appears that your basil is suffering from the feeding of slugs/snails (unless you see caterpillar poop), and a nutrient deficiency. We've included a link with info about slug/snail control and one about the needs of basil plants. The nutrient deficiency is either caused by a lack of nutrients in the soil (which may require additions of fertilizer) or too much water. Excess water damages roots (especially if temps are cool and/or coastal overcast conditions are frequent) so that the roots can't function to take up nutrients, even if you add fertilizer. Basil performs best in moderately moist, well-drained soil, and may require some fertilizer in poorly managed soils. http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn7427.html

Laceleaf Maple

This could be a Acer japonicum rubrum, or an Acer palmatum dissecgtum - both species, japonicum and palmatum come in varieties that are "shredded leaf" or "fern leaf" as the one pictured. There are cultivars that stay under 4 feet tall and others that grow 6 feet plus tall and wide. Some people prune them so that they look like bushes with foliage from ground to top (Cousin It!) and others prune them so that they are more like little umbrellas.

A couple of growing tips for these maples: Don't plant them too deeply! You'll want to see the "root flare" (Google Image it) above the soil line. Secondly, water them deeply once a week in dry weather so that they don't get leaf scorch. These small trees grow best in part-sun to part-shade.

Sick Melonssquash

There are several possible explanations for your ailing crops. They may just be getting fried. Hot sun concentrated by black tires could increase water loss past what the roots are able to absorb, even if the soil is wet. That's a good idea in cool climates, but Boise summers are warm.
Or, there are a number of bacterial and fungal wilts that are carried over from year to year in the soil. We can't tell which one it might be without a close-up of the affected plant—and sometimes a cross-section of the stem, and perhaps a microscope, is necessary.
Finally, is the soil deeper than just the height of the tires? Most crops need at least 8 to 10 inches, and 2 feet is much better. If you've cut out the mulch under the tires and loosened the soil underneath, you should be ok with that one.

Spider Mites

This looks like spider mite damage, though that seems usual for rosemary. Do you see any evidence of other insects like aphids? Look for the fine webbing and small spider like mites on the leaves. The mites themselves are very difficult to see with the human eye, so hold a piece of paper below the leaf and tap or shake slightly to see if anything falls off, or, take a spray bottle of water and spray it in the leaf axils. A magnifying glass can also help. While the mites are very difficult to see, their webs catch the water and becomes more easily visible. You may wish to show your photo to a local garden center for confirmation of the problem, so they can help you select the right control. Horticultural oils and neem oil are natural controls for mites.

Pitcher Plant

These are pitcher plants, one of several exotic and fascinating carnivorous plants whose prey-trapping mechanism features a deep cavity filled with liquid known as a pitfall trap. Sarracenia grows best outdoors as a container or potted plant. It makes an excellent addition to any sunny deck or patio. You may also grow it in a pond or fountain, but keep the crown of the plant above water. Because of its specific soil requirements, avoid planting it directly into the ground, unless you have created a specific type of bog garden. During the growing season, grow your pitcher plant outside in full sun. Provide 6 or more hours of direct sunlight for vigorous growth.

Lanceleaf Liveforever

Dudleya is a large genus of about 40 species, many of which are native to California and northern Mexico. Only a handful are common in cultivation and many are on the endangered species list. A few can only be found on some of the islands off the California coast. Most Dudleyas flower in late winter to early spring, and flower colors range from white, to yellow to bright red. D. lanceolata is a native of Southern California and Baja California as well. It is a solitary species with very fleshy, tender, lance-like, dull-green leaves. These are winter growers, often being dormant in summers. Watering some Dudleyas in the summer can simply kill them, so best to seriously reduce summer watering and be sure they are in very well-draining soil and full sun.

Nutrient Deficiency

Sometimes nutrient deficiencies occur as a result of over or underwatering the plant. We recommend watering the plant well each time you water, but only water often enough to keep the soil evenly moist, keeping in mind that the needs of the plant will fluctuate with change in the weather, and growth. The larger the plant grows, the more water will be required. If you applied a granular slow release fertilizer already it should be worked into the soil and then watered well. You may see the leaves become green again, but not always; but you should not see any further signs of deficiency. If you've applied a different type of fertilizer, don't apply anymore of any kind until necessary. You can determine how often to fertilize by following the fertilizer label directions.
