| Hi,
I have a small bed at the corner of my house. I have lived in the house for 20 years and have planted each year. Initially, the soil was heavy clay but I have amended it each year and now it is nice loose soil. I think I added lime (?) on the advice of the owner of my local nursery for those first couple of years. There are plenty of worms. HOWEVER, nothing grows there. I have a couple of hostas and I plant different annuals each year. It is a shady spot. There is nothing I haven't tried. The plants don't die. They just don't grow. Two weeks ago I planted some fuchsia, coleus and new guineas. They look fine. Seem to be flowering-but no new growth. Should I add nitrogen? It is just the strangest spot! Thank you! |

| I think that it's time you had a soil test done, don't you? At the very least, you must find out what the pH of your soil is...lime shouldn't be applied unless you know that. |

| Lime sweetens the soil if you have acidic soil and should never be added to normal PH soil. Too much lime ties up other minerals in the soil so they can't be used by the plant. The only time you add lime is if you are sure the soil is acidic with a PH test or if you see moss or the soil is green. Read the article below about the dangers of too much lime. Also read the article listed at the bottom about rebuilding the soil |

| what was bright shade 20 years ago.. could be a dark cave now ... how dark is the shade ... most 'shade' plants are only shade tolerant ... and when its too dark.. they lack vigor.. and that is what you describe ... they dont actually die.. they just dont look happy .. they dont thrive ... i agree on the soil test.. sounds like 20 years.. of just throwing stuff around.. MIGHT have created a toxic situation.. on some level ... contact your COUNTY extension office on how to do this .. it is better to FIND OUT.. rather than keep guessing about whats going on ken |

| Hi, I will get the soil tested. I haven't added lime in about 18 years... Usually I throw in a little Plant Tone and compost when I plant and call it a day. I've thought about the light issue, but the area definitely gets some sun in the morning. It is just a mystery. Thank you. |

| Well, I have a thought about how you could test whether its a soil problem or a light problem. Get a couple of cell packs of impatiens or coleus. Plant four plants in the ground, and put four in a pot and set them right next to the in-ground plants. Give each set the same treatment for a couple of weeks. If the potted ones grow and the others don't, it has to be a problem with your soil. If both sets just sit there, it's too shady. |
