Preventing Garden Diseases

Most garden diseases are caused by fungi -- microscopic relatives of the common garden mushroom. Mature fungi release millions of spores that are then carried on the wind or otherwise get transferred to our plants. And if the conditions suit them, the spores germinate and penetrate leaf tissue, creating spots, lesions, or other symptoms.

Growing Miniature Roses

Not so long ago, miniature roses were almost strictly the province of hobbyists, usually ones already bitten by the rose-growing bug. But now, thanks to the influence of European gardeners and nurseries, an entirely new category of miniature rose is available here. In fact, these florist or European-style minis are the type you're most likely to encounter at supermarkets, chain stores, and discount stores. While the two types look pretty much the same to casual observers, it's useful to understand how these florist minis compare to the familiar miniature garden roses.

Growing Citrus in Containers

For the most part, the areas where home gardeners plant the citrus trees are the same areas where citrus is grown commercially. But if space is limited or climate isn't suitable, it's still possible to enjoy these trees and their bounty year-round. How? By growing citrus trees in containers.

Calculating the Number of Bulbs To Buy

For a longer show, you can plant two types of bulbs on top of each other in the same bed. Plant smaller bulbs such as crocus on top of larger bulbs such as tulips. Dig the bed to the depth of the larger bulbs. Plant and cover these with a thin layer of soil. Place the smaller bulbs on top and cover these bulbs to the soil line.

Perennial Tulips

Listening to some gardeners talk about it, you would think that a genuinely "perennial" tulip is some kind of holy grail. The dream of a tulip that comes back and multiplies has inspired and then eluded many gardeners. Any skepticism you may have is why I hesitate to make the following claim, but here it is: Wild or species tulips are perennials. Under optimal conditions, they will come back year after year and usually increase in numbers. In many cases, gardeners find themselves pulling out some that have strayed too far.
