Winter Care for HouseplantsEveryone needs a little R and R, and for houseplants winter is the time to get it. Daylight is dramatically reduced, the air is dry, and temperatures are cool — not the perfect growing conditions. Follow these tips to keep your houseplants in shape through the winter. 
Creative Container CombinationsEveryone loves a planter overflowing with petunias, geraniums, or begonias, and containers planted with a single type of plant can be spectacular. But don't be afraid to combine different types of plants, too. You can create dramatic, professional-looking displays by following a few simple rules. 
Time to Plant OnionsPlant your sets early in the spring. Onions do best if the temperature is cool when they start to grow, and warm as they mature. 
Pruning Tips and TechniquesEarly spring is a great time to prune many trees and shrubs. Start by making sure your pruning tools are nice and sharp. Then check out the following pruning tips for successful snipping this spring. 
Seed Starting TipsThere are three excellent reasons to start plants from seed. First, you'll have many more varieties to choose from. Garden centers and greenhouses usually only offer the most popular plants and leave many new or old-fashioned varieties off the table. Starting plants from seed also can be much less expensive than buying only started plants. And finally, you have the joy and satisfaction of starting your own plants and watching them grow under your care. You have the added benefit of being able to give away extra plants if more germinate and survive than you have room for. 
Prolific and Terrific: RanunculusBrilliantly colored flowers are 'ranunculus' chief attraction, and they are indeed special. They most often come in multiple layers of delicate, crepe paper--thin petals, looking like an origami masterwork. Ranunculus (R. asiaticus) excel in southern and western gardens, and make terrific container plants everywhere. |
