Geraniums are one of the more common plants you will see on walls and balconies in Italy. They continue to bloom until frost arrives. In southern Italy, the plant continues to thrive and bloom year-round. Able to grow in most soil types, geraniums have few problems and will give even more blooms by picking off spent blooms and keeping the plant fertilized, so don't plant them too high.
- Depending on the type of home you have, make certain your pots are going to be draining out and away from your wall, especially if you have wood siding.
- If you are reusing old clay pots, brush them clean in a solution of water, detergent and a teaspoon of bleach.
- Even if your home has brick or stone walls, be careful when watering. Use a long hose wand designed for watering hanging plants and perhaps keep a step ladder nearby to help access higher plants for feeding and pinching back spent blooms.
- If you have vinyl siding, screw brackets onto the flat area of the siding and make sure you screw into woo behind the siding. If you have stone or brick walls, you need to buy a carbide bit for your drill--drilling pilot holes that fit plastic or fiber wall anchors. Drilling into mortar joints is preferred. You want brackets solidly mounted to prevent heavy pots from falling.
- Consider using bottled, liquid plant food that attaches to your hose, or use slow release fertilizer or feeding spikes. Remember that blooming plants need lots of potassium (K).
- Use a product like Soil Moist (see below) to increase the water-holding capacity of your pot's soil. Use very few crystals per pot--perhaps a sprinkling of less than 1/2 teaspoon. If you make a mistake and add too much, the crystals will swell into a gelatinous mess and possibly pop out of the top of your pot.
- Other plants to try: Begonia, Lobelia, Portulaca, Sedum (there are many trailing ones), Black-Eyed Susan Vine, Alyssum, Sanvitalia, Perlargonium peltatum, Scaevola, Ipomoea, Lantana, Verbena, Coleus,
