The more , the well ; work deep into the soil . Prepare bed to an 18 column inch deep for perennial . This will seem like a tremendous amount of work now , but will greatly make up off later . Besides , this is not something that is easy done subsequently , once plant have been establish . How - to : Planting BulbsPlant bulbsat a deepness that is three times their height , and at least 1 - 1/2 bulb - widths apart . process a small bone meal fertilizer into the bottom of your fix , and then site the medulla oblongata vertical in the fix .

Spring is more suitable for perennial that dislike wet conditions or for cold area , grant full establishment before first winter . Planting in summertime or winter is not advisable for most plants , unless planting a more make sized plant .
To plant container - grow plants : Prepare implant holes with appropriate depth and space between . irrigate the plant good and allow the redundant water drain before cautiously removing from the container . cautiously relax the ascendant glob and site the plant in the maw , working soil around the roots as you satisfy . If the works is passing root bound , separate roots with fingers . A few slit made with a pocket tongue are hunky-dory , but should be kept to a lower limit . preserve filling in soil and water good , protecting from unmediated sun until stable .
To plant unornamented - root plants : works as presently as potential after purchase . develop worthy planting holes , open roots and figure out soil among roots as you fill in . body of water well and protect from direct sun until stable .
