Caring for Your Christmas Tree
Wednesday, December 7th, 2011
Now that you have selected the perfect Christmas tree, here are some tips for keeping it fresh through the holiday season! If you follow the steps below and treat your fresh cut tree as you would a bouquet of flowers, you can enjoy its warm glow into the New Year!
With a pre-cut tree, it’s vitally important to make a fresh cut across the bottom. This is because after a tree is cut, its sap will form a seal across the base after about 3 hours. A fresh cut, at home or at the nursery, will ensure that your tree can absorb water and that its needles will stay fresh.
As soon as possible, get your tree in water! If you aren’t going to trim it right away, place it in a bucket of water until you are ready (if your tree dries out in the stand, another fresh cut will be necessary). Your tree will “drink” more in the first few days, so be sure to keep your stand topped off.
A variety of organic products are available to keep your tree fresher longer. At the nursery, we recommend spraying your tree with Wilt Stop to seal its needles and slow the drying process. Mixing Tree Life nutrient powder in with the first watering will also help to keep your tree soft and green.
Try keeping your tree away from heat sources, as these tend to speed the drying process. Lastly, check that your lights and outlets are in good working order and are designed for use with indoor trees. If you follow these steps, you will never have to miss the joy and warmth of a real Christmas tree!
Merry Christmas!

Frantic About Fungus?
Friday, July 1st, 2011
Is There A Fungus Among Us?
The roller coaster weather pattern we experienced this spring switched back to prolonged wet and chilly weather last week. While the moisture was needed as soils were quite dry, the constant wetness creates ideal conditions for disease causing organisms. Disease causing organisms are natural inhabitants of the soil and infect grass plants when the environmental conditions are favorable or the plants become weakened by poor growing conditions. The pathogen is favored by warm, humid weather, wet or compacted soil, drought stress, and low mowing heights.
The spores of these parasitic forms of plant life are spread by wind, air, water, animals, people, insects and mowing.
Important steps to manage plant diseases include proper soil preparation, proper selection of grass seed including ones with a natural genetic resistance to diseases, and application of proper cultural practices.
If you have a fungus, spraying now with Dr. Earth Natural & Organic Fungicide effectively combats a broad spectrum of fungal diseases found in your lawn, on your vegetables, flowers & shrubs. Dr. Earth can be used both as a foliar spray for your plants or a soil drench for your lawn & trees.
Once you have sprayed the fungicide, you should then fertilize your lawn & your plants with Fire Belly Bio-Blast to reintroduce beneficial mycorrhizal fungi.
Healthy soils that have the ability to fight off disease causing pathogens increase the chances of plant survival and thus control the pathogens so they will not multiply in great numbers. Beneficial microbes fill up the available spaces in the soil so that pathogens cannot become established and destroy healthy plants.
Most lawns recover with changes in environmental conditions and proper cultural practices. For severe cases due to poor soil, poor grass selection, or excessive thatch, the best solution may be renovation. Please give us a call with any questions or to schedule a courtesy consultation for a lawn renovation.

Most Un-Wanted: Cedar–Apple Rust
Sunday, August 8th, 2010
Wanted For: defoliating apple leaves & for just being gross!!
Description: bright yellow-orange-red spots on apple leaves and orange galls with ‘horns’
Hangout: juniper (eastern red cedar) & apple trees including crabapples
Kryptonite: Lime –Sulfur Spray, Home Orchard Spray
The fungus that causes this disease moves back-and-forth between Eastern red cedars (actually junipers) and both fruiting & ornamental apple trees. In order to complete its life cycle this fungus must spend part of its life on both. Therefore, it is possible to eliminate the disease by eliminating the cedars within the given area of the apple tree. However, the spores can be wind borne up to 2-3 miles, so eradication of the disease is often impossible or impractical. Nonetheless, if cedars are not too numerous on your property, the removal of junipers around the immediate apple tree can certainly reduce the spores reaching the apple foliage & fruit.
The spores drift through the air mostly at night and early morning. If it lands on the apple’s leaves & fruit and remains wet for 4-6 hours, the spores infect the leaves of the apple tree. After several weeks, yellow spots develop on the infected apple leaves and fruit. By mid-summer the spots appear slightly raised and light-colored & are visible on the underside of the leaf. Spores are released and the wind carries them to nearby junipers. Infected juniper needles and twigs show no symptoms of infection initially. Inspect them closely the next spring for small, green swellings (immature galls). The galls reach full size by the end of the next growing season but do not mature and develop the orange gelatinous tendrils until the following spring (about 20 months after infection.) This bizarre-looking structure is actually the fruiting stage of the fungus. The “horns” release the spores that infect the apple trees.
Many sulfur fungicides are effective against rust. Begin spraying in spring and repeat throughout the summer as needed. Spraying the juniper is not recommended because cedar-apple rust rarely causes significant damage to this host. Prune dormant galls from juniper during the fall, winter and early spring before the orange tendrils begin to erupt from galls.

Most Un-Wanted: Lily Leaf Beetle
Sunday, August 1st, 2010
Wanted For: an invasive species that dines on & destroys ornamental lilies, also exhibits an interesting habit of personal hygiene – covering themselves with their own excrement
Description: beetle has bright scarlet body & black legs, head, & antennae and the Larvae resemble slugs with swollen orange, brown, yellowish or even greenish bodies and black heads
Hangout: asiatic lilies
Kryptonite: Neem, Spinosad, Pyrethrins
The adult beetles stay alive throughout the winter and emerge early in the spring, when they begin looking for food and a mate. The adult females lay their eggs on the underside of lily leaves and the females produce between 250 and 450 eggs. The eggs appear in April or May and hatch within eight days.
The young larvae feed on the underside and the upper surface of lily leaves and sometimes on lily buds. This feeding period, which lasts 16 to 24 days, is the most destructive. From there, the beetles drop to the soil and pupate, emerging as adults about 16 to 22 days later & feed throughout the rest of the growing season.
And their personal hygiene leaves something to be desired: they secrete and carry their excrement on their backs. While they feed, the lily leaf beetles cover their bodies with their own excrement, giving them a grotesque appearance. It is some sort of defensive mechanism – it makes them look like a bird dropping, warding off predators and parasites.
If you only have a few plants in your garden, hand-picking adults and eggs can be effective (we prefer not to handle larvae, although there is no danger in doing so). Neem is most effective – it will repel beetles and kill young larvae, but must be applied every 5 to 7 days after the eggs hatch. Spinosad will kill the larvae.

Keep an Eye out for Two Tomato Trouble Makers
Monday, July 26th, 2010
Blossom End Rot
Blossom end rot looks like the bottom of the tomato is rotting away. The bottom is shrunken and black.
Blossom-end rot is a physiologic disorder associated with calcium. Calcium is required for normal cell growth. When a rapidly growing fruit is deprived of necessary calcium, the tissues break down, leaving sunken lesion at the blossom end. Blossom-end rot is induced when demand for calcium exceeds supply. This may result from low calcium levels, drought stress, excessive soil moisture fluctuations as well as rapid, vegetative growth due to excessive nitrogen. This reduces uptake and movement of calcium into the plant.
Simply, it is a lack of calcium & a watering problem. The plant needed calcium at some point in its development of the fruit and there wasn’t enough water to transport the calcium up to the fruit. So this condition develops.
The solution is to fertilize with Calcium (FOLI-CAL) and be consistent with your watering.
Monterey FOLI-CAL
Tomato Cracking
Cracking of the skins is mostly a problem of inconsistent watering or water availability. The plants take it up and grow too quickly for the skins to expand. It mostly seems to happen when you water after a dry spell.
The solution is to water more thoroughly and more consistently. You will get more consistency and far fewer cracks.
