If soil opus is weak , a stratum of topsoil should be considered as well . No matter if your soil is moxie or mud , it can be improved by adding the same thing : constituent matter . The more , the better ; work late into the soil . Prepare beds to an 18 in deep for perennial . This will seem like a grand amount of work now , but will greatly pay off later . Besides , this is not something that is easily done later , once plants have been established . How - to : Planting BulbsPlant bulbsat a depth that is three times their height , and at least 1 - 1/2 bulb - width asunder . Work a small bone meal fertilizer into the bottom of your hole , and then put the lightbulb vertical in the gob . The more pointed end is almost always the top . If you have worry secernate which is the top , reckon for grounds of where a stem or source were last year .

This will foreclose them from entirely taking over an surface area to the exclusion of other plants , and also will increase air circulation thereby reducing the relative incidence of diseases like botrytis and powdery mildew .
Many species also blossom abundantly and produce ample seed . As blooms fade it is advisable to deadhead your plant life ; that is , to remove spend flowers before they shape seed . This will prevent your plant from seeding all over the garden and will conserve the considerable DOE it pick out the flora to farm seed .
As perennials mature , they may form a dense root mass that eventually lead to a less vigorous plant life . It is advisable to occasionally thin out a stand of such perennials .

Spring is more desirable for perennial that dislike wet conditions or for colder area , allowing full governing body before first winter . Planting in summer or wintertime is not advisable for most plants , unless plant a more build sized plant life .
To plant container - rise plants : Prepare planting holes with appropriate depth and space between . Water the plant good and let the excess water drain before carefully removing from the container . cautiously loosen the rootage chunk and localise the plant in the hole , working grime around the theme as you fulfill . If the plant is extremely radical spring , freestanding root with fingers . A few pussy made with a pocket knife are hunky-dory , but should be kept to a minimum . Continue filling in ground and urine thoroughly , protecting from direct Sunday until stable .
To plant bare - root plant : plant life as shortly as possible after leverage . Prepare suitable planting yap , distribute root and work soil among roots as you fill in . Water well and protect from unmediated Dominicus until stable .
