Gardening Calendars


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, [Read More…]


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 [Read More…]


February Garden Calendar

HOME (Indoor plants and activities) Check water levels in cut flowers daily. Check stored produce and flower bulbs for rot, shriveling, or excess moisture. Discard any damaged items. Most houseplants require less water in the winter because growth is slow or stopped. Check the soil for dryness before watering. Move houseplants to brighter windows, but don’t place plants in drafty places or against cold windowpanes. Early blooms of spring-flowering bulbs can make good gifts for [Read More…]


January Garden Calendar

HOME (Indoor plants and activities) Keep holiday poinsettias and other plants near a bright window. Water as top of soil becomes dry. Increase humidity around houseplants by grouping plants together, placing them on a pebble-water tray or running a humidifier. Check stored produce and tender flower bulbs and roots for rot, shriveling or excess moisture. Remove and discard damaged material. Repot houseplants as they outgrow current pots. YARD (Lawns, woody ornamentals and fruits) Check young [Read More…]


December Garden 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 [Read More…]


November Garden 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.

October Garden 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 [Read More…]


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 Thanksgiving 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 55F will cause flower buds to set without dark treatment. Dig and repot herbs, or take cuttings, [Read More…]


August Garden Calendar

Visit the Purdue Plant Info to Go/Purdue Master Gardener booth at the Indiana State Fair Aug. 4-20. Bring your gardening questions to the booth in the Purdue Extension Ag/Hort Building. HOME (Indoor plants and activities) Take cuttings from 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 planting. Cut [Read More…]


July Garden Calendar

JULY HOME (Houseplants and indoor activities) Watch closely 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 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 [Read More…]
