Gardening Checklist

May 15-21, 2009

Feed roses monthly with rose fertilizer. Keep a sharp look out for blackspot, powdery mildew and rust that can develop on the leaves. If you aren’t sure of what is damaging the roses bring a sample into your local California Certified Nursery Professional ™ for a quick diagnosis.
Stake or cage all vining and tall growing vegetables when you plant the seedlings. This way you will avoid disturbing the root system as the plants mature.
It’s time to plant summer blooming annuals. Try hot weather lovers: celosia, petunias, marigolds, dahlias, nicotiana, salvias and zinnias to mention a few.
Plant a red, white and blue flowerbed this month to celebrate and honor those who have fought to protect our freedom. It will still be going strong to celebrate the Fourth of July.
Use succulents for fire protection in addition to their sturdiness, foliage colors and sculptural forms, succulents contain lots of water in their leaves. This makes them an excellent choice for fire-scaping. Aloe, cotyledon, crassula, echeveria and sedum are all good options.
Acidify your hydrangeas. To keep your blue-flowered hydrangeas blue, acidify the soil now. Apply aluminum sulfate, which is often packaged expressly for hydrangeas. Follow the directions.
