Daisy-grubber
For digging out lawn weeds with their roots.
Damping off
Damping off is when young seedlings keel over and die from fungal attack. It causes the stem to rot off at soil level. It occurs when drainage is poor and when seedlings are overcrowded or damaged. The result of soil borne diseases and over watering. Sterilized potting soil and careful sanitation practices usually prevent this.
Deadheading
Removing flowers as they fade to prevent the plant from wasting valuable energy on forming seeds and to keep plants looking tidy. Deadheading extends the life of annual_plant flowers and can prolong the flowering of perennials, especially roses.
Division
A way of multiplying a plant by cutting or pulling a large clump into smaller portions.
Deciduous
Deciduous trees and shrubs shed all their leaves in autumn and early winter, Oak and Maple trees are good examples. Plants lose a lot of water through their leaves, especially in windy weather, and this can be lethal in winter, so deciduous plants protect themselves by dropping their leaves and resting dormant until growth starts again in spring.
Determinate
A variety whose stems stop growing once they’ve produced their first truss of flowers. Sideshoots then develop.
DETHATCH
Process of removing dead stems that build up beneath lawn grasses.
DIBBER/DIBBLE/DIBBLER
A pointed tool used to make holes in the soil for seeds, bulbs, or young plants.
DIEBACK
This condition is water, nutrient, disease, insect, or pruner inflicted in the area where part of the plant is dying.
DIOCECIOUS
A plant which bears either male or female flowers. (Compare to Monoecious)
Disbud
To remove buds, either completely to prevent flowering or selectively to increase the size of remaining flowers.
DISC/DISK
The flat central part of a compound flower. It is made up of short, tubular florets.
DISTILLED WATER
Pure water free from dissolved salts. Formerly made by distillation, now produced chemically by demineralisation.
DIVIDING
The process of splitting up plants, roots and all that have began to get bound together. This will make several plants from one plant, and usually should be done to mature perennials every 3 to 4 years.
DIVISION
A method of propagating plants by separating each one into two or more sections and then repotting (i.e. Iris is easily propagated in this manner.)
DOLOMITIC LIMESTONE
Sometimes used when ‘liming’ soil that has an acid pH level that is too high. As it contains calcium and magnesium carbonate it should be used only with soils that are also deficient in magnesium as well. See Calcitic Limestone.
Dormant/Dormant Period
The time when a plant has naturally stopped growing and the leaves have fallen or the top growth has died down. The dormant period is usually, but not always, in winter. Compare Resting Period.
DORMANCY
The yearly cycle in a plants life when growth slows and the plant rests. Fertilizing should be withheld when a plant is in dormancy.
Dot plant
A tall specimen plant used to add height to and contrast with arrangements of lower-growing plants, especially in summer bedding schemes.
DOUBLE DIGGING
A method of deep cultivation. Preparing the soil by systematically digging an area to the depth of two spades.
DOUBLE FLOWER
The Latin name for this is “flore pleno.” It refers to flowers that have many petals present, such as roses.
DOUBLE POTTING
An American term for placing a potted plant in a larger pot with damp peat moss surrounding it. The peat is kept moist and provides a humid evaporative effect for the potted plant nestled between it.
DRAWN
Excessively tall and weak growth, caused by plants being grown in too little light or too closely together.
DRILL
A shallow furrow into which seed is sown.
DRIP IRRIGATION
A trickle irrigation system. Highly recommended for soaking the soil well. Used where water sources are limited.
DRIP LINE
The circle which would exist if you drew a line below the tips of the outer most branches of a tree or plant.
Dry set
This happens in hot, dry conditions when tiny developing fruits stop swelling and drop off.
DWARF
Shorter than its normal growth. Each family of plants has a height recommendation for dwarfness.
