How Much Grass Clippings Is Too Much Before Slit Seed
Comments (3)I think you will be OK. You could rake up any thick accumulation of clippings, otherwise you should be able to slit seed right into the soil. Good luck and keep em wet. Bill Hill...See MoreHow much pink is too much?
Comments (20)First and foremost, I believe it comes down to what you love to surround yourself with. seil is happy with different colors mixed together, and from what I've seen of her garden it works beautifully. She probably has a good eye for color and subconsciously chooses roses that look good together even if not aware of that on a conscious level. Terri likes warm pinks while I adore the cool ones, and Meredith has cleverly combined both by separating them with her entry porch. We each have a different style that works for us. The other consideration is the background in which you plant roses. If you have a smaller garden in the suburbs you can probably do whatever you prefer without worrying about clashing with a larger background. Part of my backyard is a wild, boulder-strewn hill and the surrounding scenery is natural, with hardly a house in view. Most of my less than two acres has been left natural with the garden only on the flat area surrounding the house. For that reason it's very important to me to make the garden blend with the landscape. mendocino rose, with vastly larger amounts of land and a huge number of roses, has chosen a different path by making her rose garden a separate entity, with soft and bright colors mixed together. It works beautifully because she has over 1500 roses which can easily be seen as separate from their hilly background because of the huge impact that large number of roses makes. Fortunately, there's something for everyone, which is what makes looking at others' gardens so fascinating. There are endless ways to incorporate roses into a garden, just as there are endless numbers of gardeners to implement those ways.

Comments (10)glib -- I like this idea! Thanks -- and I just happen to have a pile of unfinished compost. wayne -- the tilling I did this year, to make things easier, was done with an electric mantis tiller, and it basically pulverized the soil. My old way of potatoes (the hard way) was some digging. This way certainly seems damaging to the soil structure, since there are no apartment complexes left for the SFW folks to live in. Maybe a rototiller would do less damage? But I can't handle a rototiller by myself, so I bought this mantis and the blades are sharp and fast....See MoreHow much is too much (electrical)
Comments (53)No mownie. "Because electrical flow must be maintained, any "excess unregulated current" remaining (after the Zener diode establishes "regulated output" into the main buss) will be diverted, or "shunted" into the ground conductor of the overall machine." A flash light battery has EMF and none of its current is diverted when it is not under load. Current-voltage characteristic of a Zener diode with a breakdown voltage of 17 volt. Notice the change of voltage scale between the forward biased (positive) direction and the reverse biased (negative) direction. A Zener diode is a type of diode that permits current to flow in the forward direction like a normal diode, but also in the reverse direction if the voltage is larger than the breakdown voltage known as "Zener knee voltage" or "Zener voltage". Named for Clarence Zener, discoverer of this electrical property. A conventional solid-state diode will not let significant current flow if it is reverse-biased below its reverse breakdown voltage. When the reverse bias breakdown voltage is exceeded, a conventional diode is subject to high current flow due to avalanche breakdown. Unless this current is limited by external circuitry, the diode will be permanently damaged. In case of large forward bias (current flow in the direction of the arrow), the diode exhibits a voltage drop due to its junction built-in voltage and internal resistance. The amount of the voltage drop depends on the semiconductor material and the doping concentrations. A Zener diode exhibits almost the same properties, except the device is specially designed so as to have a greatly reduced breakdown voltage, the so-called Zener voltage. A Zener diode contains a heavily doped p-n junction allowing electrons to tunnel from the valence band of the p-type material to the conduction band of the n-type material. In the atomic model, this tunneling corresponds to the ionization of covalent bonds. The Zener effect was discovered by physicist Clarence Melvin Zener. A reverse-biased Zener diode will exhibit a controlled breakdown and let the current flow to keep the voltage across the Zener diode at the Zener voltage. For example, a diode with a Zener breakdown voltage of 3.2 V will exhibit a voltage drop of 3.2 V if reverse bias voltage applied across it is more than its Zener voltage. However, the current is not unlimited, so the Zener diode is typically used to generate a reference voltage for an amplifier stage, or as a voltage stabilizer for low-current applications. The breakdown voltage can be controlled quite accurately in the doping process. Tolerances to within 0.05% are available though the most widely used tolerances are 5% and 10%. Another mechanism that produces a similar effect is the avalanche effect as in the avalanche diode. The two types of diode are in fact constructed the same way and both effects are present in diodes of this type. In silicon diodes up to about 5.6 volts, the zener effect is the predominant effect and shows a marked negative temperature coefficient. Above 5.6 volts, the avalanche effect becomes predominant and exhibits a positive temperature coefficient. In a 5.6 V diode, the two effects occur together and their temperature coefficients neatly cancel each other out, thus the 5.6 V diode is the component of choice in temperature critical applications. Modern manufacturing techniques have produced devices with voltages lower than 5.6 V with negligible temperature coefficients, but as higher voltage devices are encountered, the temperature coefficient rises dramatically. A 75 V diode has 10 times the coefficient of a 12 V diode. All such diodes, regardless of breakdown voltage, are usually marketed under the umbrella term of 'zener diode'. I conclude: you leak off all your excess current you want. I think I will keep mine....See Morewasabi_VA
