my new bed is killing all my bulbs and perennials! why???
Comments (8)Is your planter on bare ground or directly on a hard surface (eg concrete or a rocky patch)? What's the drainage like? For example - I made a 'tabletop' planter which has a slatted bottom. I lined it with overlapping plastic bags then put in a mix of composts - one of which is very rich. Despite being three feet off the ground, with seeping drainage, and being only 8" deep - the bottom layer of the mix is very 'cluggy'. Further - despite being very well-rotted compost, the growth from the first year was disappointing. Using the same mix for a second year, after weathering, the results have been much better. The leaves. I may have misread. I gained the impression that you had used them as a further 'water-holder' layer. Sometimes buried material can be a bit toxic while it rots. I'd use leaves on the top, as a protective mulch over a serving of, say, blood and bone (but I don't have critters, as such :-)) ) Not buried. (That's not a lot of depth for bigger bulbs to get their roots down. At least four inches above and below the actual bulb, if they have to dodge the frost.) The sand. Nononono. Grit, yes. Sand and compost is for serious water-lovers. Gunnera and pondside plants. 3-5mm sharp grit well stirred through. A good gritty mix encourages root development. If you have mountain streams in your area with shingle beaches - look at the root development of plants growing in that medium. The tops might be stunted but the roots spread far and wide as they forage. If your planter has settled over winter - I'd add some genuine soil. Dirt out the garden. Not subsoil clay. Reasonable topsoil, if you have it. In an outdoor planter of the size you have the soil seems to add 'sturdiness' to the mix and the plants. One bucket of dirt, one of compost, half of grit. Later on, I'd add the ancient cowpats and good garden compost to suit the taste of whatever I was planting. And add an organic mulch if water-loss, or wind is an issue in the garden, once the soil has warmed up and growth is well under way. For now - I'd rescue the perennials and pot them up fairly tightly until they've developed a vigorous root system again. A gritty mix will help for most of them, so long as you water with care. You didn't list what you were growing. For a mix as juicy as you've offered, I'd be growing things such as polyanthus, or Dahlias, maybe Hostas and Dicentra. For something like tuberous Begonia - I'd wait for the second year. If you bought pot-grown perennials and they were slightly root-bound - remember to open the base of the rootball a little so they can start spreading. If they were slips and bare-rooted - don't expect wonders this year. Some can take up to two years to settle in and then shock you by becoming garden thugs :-(. Meantime, you could sneak in a few coloured lettuces and use the benefits tastily! Or try some bedding Impatiens and Lobelia while the soil ingredients settle down....See MoreWhy would I try to rid my lawn of this weed?
Comments (3)The gardener's definition of a weed is any plant that is growing in a place that you don't want it to be growing. If you want it there, it is not a weed. My wife asks people the following question: "what is the difference between a perennial and a weed?". Her answer: "$9.99". There is some truth to it. I'd identify the plant, however. You may like it now, but will you like it if it spreads over the entire yard? Into your gardens? Know the plant's habits and profile and you can make an informed decision. It really is that simple....See MoreWeeds growing in cracks of my decorative rocks
Comments (5)Over time dust and organic matter accumulates in the spaces between rocks or the cracks between paving blocks which then gives those unwanted plants someplace to root and grow. They are not from the soil below, usually, but in the spaces between what ever is placed there. The best means of keeping the unwanted plant growth out of there is to pull up all the material and clean out the accumulated dust and organic matter. Short of that is to spray plant poisons that will cause more organic matter (those now dead plants) to accumulate giving more material for other unwanted plants to grow in and polluting the planet we live on. kimmq is kimmsr...See MoreRevamp a river rock bed patch overgrown with weeds...
Comments (2)Weed fabric and river rock are both disasters that I would never use! The majority of weeds seed into place - blown in on the wind or carried in on the feet or body of both people and wildlife - rather than come up from the soil under the fabric Plus the weed fabric prevents soil organisms (e.g. worms) from pulling organic matter into the soil and the worms leave to find somewhere where they can access the surface. Their tunnels - which provided routes for air and water to move through the soil - collapse. So the soil becomes dry, hard, and nutrient poor. Fallen leaves and other plant debris collect on the river rock and rot down to become soil that weed seeds germinate on The weed roots grow down through the weed fabric. To remove the weeds you need to move rocks out of the way and pull the weeds’ roots out of the weed fabric. VERY difficult to do. Probably the best thing you can do is remove the rocks and the weed fabric. If the area is shady enough to grow hostas, plant it with the largest hostas you can find, which will make a continuous row of large dense leafy cover to shade out weeds. If the area is too sunny for hostas, can you grow grass there right up to the house? Mowing grass is likely to be less work than constantly removing weeds. People have the totally unreasonable expectation that weed fabric and rocks are going to reduce work - but the combination almost always turns into a mess that creates MORE work!...See Moreawakener
