Home gardens and landscapes should be compatible with their respective climates. For local chaparral climates, plants that do not need much watering through the long and dry summers are appropriate. Aquatic plants are the extreme opposite. They require regular replenishment of the ponds that...

Old fashioned irrigation systems were quite thorough, and technically sustainable. They broadcast generous volumes of water over any vegetation that required it. Their systems were too simple to need much adjustment. Their metallic composition was very resilient. That is why so many old systems...

A tree is a woody perennial plant with a single tall trunk and branches. Banana trees and tree ferns lack both branches and wood. Arboriform yuccas develop branches but are not woody. Palm trees are no better. Some develop a few trunks but without...

Winter is bare root season, which is the best time for installation of deciduous fruit trees. It is also the best time for dormant pruning of deciduous fruit trees. Evergreen fruit trees do not get much attention. Installation and any pruning of evergreen fruit...

Pruning at the proper time has been a concern all winter. Dormant pruning was timely as soon as defoliation began. It remains timely almost until bloom. Pollarding and coppicing are generally although unnecessarily a bit later within that range. Spring pruning begins soon after...

Spring bloom is the most colorful color in the garden here. It is not the only color, though. Some deciduous foliage will provide color at the opposite end of the year. Bark can add a bit of color, particularly while deciduous trees defoliate for...

This is extreme dormant pruning. Pollard and coppice pruning involve complete removal of all new growth. They typically involve growth from a previous season annually. A two-year cycle involves growth from two previous seasons, and so on. This repetitive pruning to the same origins...

Saturation of the soil should be a rare problem within the local chaparral climates. Water is a limited resource. That is why plants that are not native or endemic to other chaparral or desert climates rely on supplemental irrigation. Many exotic species would not...

Home gardens are becoming shadier. Modern homes are taller to fit closer together. Modern fences are taller to compensate. Densely evergreen trees and large shrubbery compensate more. Taller homes and fences, and denser vegetation, shade more of their smaller modern parcels. Not much sunlight...

Maya Angelou likely enjoyed gardening. She said, “In diversity there is beauty and there is strength.” That is how the healthiest of ecosystems, including home gardens, function. Vegetable gardens are generally diverse. However, each group of a particular vegetable is rather homogenous. Crop rotation...
