Gardening Calendars


December Gardening Calendar


HOME (Indoor plants and activities) Check houseplant leaves for brown, dry edges, which indicates too little relative humidity in the house. Increase humidity by running a humidifier, grouping plants or using pebble trays. Extend the lives of holiday plants such as poinsettias and Christmas cactus by placing them in a cool, brightly lit area that is free from warm or cold drafts. Houseplants may not receive adequate light because days are short and gloomy. Move […]

October Gardening Calendar


HOME (Indoor plants and activities) Keep poinsettia in complete darkness for 15 hours each day — for example, between 5 p.m. and 8 a.m. — for eight to 10 weeks until red bracts begin to show. Pot spring-flowering bulbs to force into bloom indoors. Moisten soil and refrigerate 10 to 13 weeks. Transfer to a cool, sunny location, and allow an additional three to four weeks for blooming. Houseplants, especially those grown outdoors during the […]


September Garden Calendar


HOME (Indoor plants and activities) Prepare storage areas for overwintering tender flower bulbs and garden produce. Thanksgiving (or Christmas) cactus can be forced into bloom for the holidays. Provide 15 hours of complete darkness each day — for instance, from 5 p.m. to 8 a.m., for approximately eight weeks. Keep temperature at about 60-65 degrees F. Temperatures of 55ºF will cause flower buds to set without dark treatment. Dig and repot herbs, or take cuttings, […]


August Garden Calendar


Visit the Purdue Plant Info to Go/Purdue Master Gardener booth at the Indiana State Fair (Aug. 3-19.) Bring your gardening questions to the booth in the Purdue Extension Ag/Hort Building. HOME (Indoor plants and activities) Take cuttings from annual garden plants such as impatiens, coleus, geraniums and wax begonias to overwinter indoors. Root the cuttings in media such as moist vermiculite, perlite, peat moss or potting soil, rather than water. Order spring-flowering bulbs for fall […]


July Garden Calendar


HOME (Houseplants and indoor activities) Closely watch houseplants that have been set outdoors. They need more water than they did indoors. They can dry out rapidly in hot, summer breezes. Propagate houseplants by taking cuttings from vigorously growing plants. Place the cut end in rooting media (such as perlite, vermiculite, or peat moss soil mix). Enclose in plastic and keep out of direct sunlight. YARD (Lawns, woody ornamentals, and fruits) Keep newly established plants watered […]


June Garden Calendar


HOME (Houseplants and indoor activities) Indoor plants will require more frequent watering and fertilizing as they increase their summer growth. You can move houseplants outdoors to a shady location, but pay close attention to their watering needs. Cut garden flowers for indoor beauty. Recut the stems again just before placing in water. Add a floral preservative, and change the solution frequently. Root cuttings of houseplants and garden plants to increase your collection or share with […]


May Gardening Calendar


HOME (Indoor plants and activities) Many indoor plants can be moved to shady locations outdoors but only after the danger of frost has passed. Plants will dry out more often outdoors, so keep a close eye on soil moisture. Sinking the pots in soil will help slow down moisture loss. Now is a good time to take cuttings of houseplants to increase a collection or share with friends. Root cuttings in media, such as vermiculite, […]


April Garden Calendar


HOME (Indoor plants and activities) Start seeds of warm-season plants (including tomatoes, peppers, eggplant, marigolds, zinnias, and petunias) indoors for transplanting later to the garden. Harden off transplants started earlier in spring before planting outdoors – gradually expose the young plants to outdoor conditions of wind, brighter sunlight, and lower moisture. Apply fertilizer to houseplants according to label directions as days grow brighter and longer and new growth begins. Foliage plants require relatively high-nitrogen fertilizer, […]


March Garden Calendar


HOME (Indoor plants and activities) Begin fertilizing houseplants as new growth appears. Remove spent leaves and flowers to improve appearance and encourage more blooms. Start garden seeds indoors for transplanting outdoors later in spring. Check stored bulbs and produce for decay; discard damaged items. Prune, repot, and clean houseplants as needed. YARD (Lawns, woody ornamentals and fruits) Prune trees and shrubs (except those that bloom early in spring) while plants are still dormant. If you […]
