Since were talking about container plants, what fertilizer should I use and how often?
On annuals that grow rapidly and bloom continually through the summer such as impatiens, begonias or lantana or tropical plants like mandevilla and hibiscus, apply a 3-4 month timed release fertilizer (ferti-lome Start-N-Grow) at planting and supplement with a water soluble spray feed (Blooming and Rooting) every 2 weeks. A lot of water and nutrients flows out the drain hole so dont be afraid to fertilize. When you fertilize container plants, you just need to mist the foliage and spray a little in the container. If its dripping off on the deck, you are wasting productand money! For indoor plants that arent watered as often, use an organic like Sea Tea or fish emulsion once a month from March through September.
