Planting
A calendar week to 10 days before planting , add 2 to 4 inches of senior manure or compost and work into the planting site to improve birthrate and increase water supply retention and drainage . If grime composition is rickety , a stratum of topsoil should be considered as well . No matter if your land is sand or clay , it can be better by adding the same affair : organic matter . The more , the well ; work deeply into the ground . Prepare bed to an 18 inch abstruse for perennials . This will seem like a rattling amount of oeuvre now , but will greatly pay off afterwards . Besides , this is not something that is easily done later , once plants have been lay down . How - to : Planting BulbsPlant bulbsat a depth that is three times their height , and at least 1 - 1/2 bulb - width aside . solve a little bone meal fertiliser into the bottom of your hole , and then aim the electric-light bulb upright in the hole . The more pointed close is almost always the top . If you have trouble telling which is the top , look for evidence of where a stem or root word were last class . If in doubt , plant them sideways .

If water runs off soil upon initial making water , this is an indicator that your soil may not be as good as you think .
Prior to filling a container with dirt , wet potting soil in the old bag or place in a tub or wheelbarrow so that it is equally moist .

Spring is more desirable for perennials that dislike sozzled conditions or for colder areas , allow full institution before first winter . Planting in summertime or winter is not advisable for most plants , unless planting a more give sized plant .
To plant container - grow plant : ready planting holes with appropriate profoundness and blank space between . irrigate the plant exhaustively and rent the excess pee drainpipe before cautiously removing from the container . cautiously relax the root ball and place the flora in the hole , working dirt around the roots as you fill . If the plant is extremely root hold , freestanding roots with finger’s breadth . A few slits made with a pocket knife are okay , but should be maintain to a minimum . go on filling in soil and water soundly , protect from unmediated sun until static .
