Symptoms of Virus Infection
Common signs of virus infection are stunted growth and mottled patterns on the leaves (often referred to under the general term "mosaic").

New shoots arid leaves, however, begin to show abnormal symptoms as they grow. Other resources include:, Randall, Pruning Established Roses

What's Inside

Propagating Roses - Propagation by cuttings is generally not as successful as by budding. Commercially the method is quite impracticable since a shoot which provides several buds yields only one cutting, and budding is much quicker. Even if the cutting should root, it may su... more

Seed Stratification - Certain seeds will not germinate until they have been subjected for some weeks or even months to low temperatures and humid conditions similar to those which occur in nature after they drop from the parent plant and are covered with fallen leaves and othe... more

Know Your Tree's Soil - A most important factor and one that determines the success of your garden is knowing what kind of soil you have and then choosing shrubs and trees that will be suited to it. Many plants will not grow well in acid or alkaline soils, so it is wise to take... more

Lawn Plugs - Plugging - Plugs are pieces of sod, one and a half or two inches or so in diameter, of creeping grasses. When planted, they quickly grow together and cover the ground. They differ from sprigs in that each consists of many rather than a few shoots and includes the so... more

How to Lay Lawn Sods - Prepare the soil on which turf is to be laid exactly as for seeding but with its surface as much lower than the finish grade as the sods are thick. Make sure that the soil is moderately compacted and then loosened slightly on its surface by raking. This h... more

Peat moss and plants that like lime - Peat moss can be safely used and it will improve the structure of the soil, increase its water holding capacity and make it easier to work. But, as peat moss has an acid reaction, lime must be used to counter the acidity. A dressing of lime, say a good... more

Cactus Grafting - Cactus grafting is another form of propagation which should be avoided if possible, unless it is essential to save a plant, but growers should know the various methods of grafting. Some plants have to be grafted—crests and variegated plants, but generally... more

Indoor Garden Planters - Planters can be of any dimensions and shapes appropriate to their locations. Some enthusiasts have floor level, bed-type planters large enough to include a fountain and perhaps a path to make servicing them easier. These are truly indoor gardens! But most... more

Testing your soil - Soil-testing kits available and by and large they do a very good job of accurately testing your soil. However, if you are only interested in knowing if your soil is acid or otherwise, without worrying about degrees of acidity or alkalinity, here is a simp... more
