Plants with opposite leaves = flat cut just above pair of buds;
88
Describe canker on trees
AKA "dieback";
Large fissures in bark, with dry, cracking bark around them;
Area where cambium and bark have been killed;
Usually caused by a fungus and sometimes a bacterium;
Common causes:
- poor pruning
- trimming too close to base of branch
- pulling branches
- allowing branches to fall
Wounds are caused that take time to heal, exposing large areas of cambium and encouraging infection;
If canker spreads within branch or stem, site becomes brittle and can snap;
Nutrient and water supply eventually become cut off and entire branch dies.
89

Avoid watering foliage or water sitting on foliage;
Use nematodes for vine weevil problems.
94
General mix for rock and scree gardens
1 part loam/garden soil (sterilised!)
1 part sand/grit/gravel
1 part leaf mould/peat substitute
SCREE gardens - use THREE parts grit and NO sand!
If using acid-loving plants, lower soil pH by increasing amount of acidic peat substitute in preference to loam.
(pH must be appropriate for the plants!)
95
How to create a ROCK GARDEN
Remove weeds and debris first!
Create mounds with rubble and cover with upside-down turves;
Place rocks to create rocky outcrops (prop up with smaller stones)
Get help with heavy rocks - use crowbar to lever!

Once larger rocks are placed, add more general mix and firm in;
Plant plants as desired, using trowel;
Top-dress with gravel mulch;
Water thoroughly.
96
How to create a SCREE garden
If site isn't sloped, need to create a gentle slope;
Use rubble to create a roughly level bed on slope.
Bed should be around 15cm deep and topped with inverted turves;
Top this with 15cm scree mix and firm in.
Water before planting;
When planting, remove as much growing media from around roots as possible - spread roots out in planting hole;
Firm plants in place;
Top dress with larger stone chippings;
Water thoroughly.
97
How to create a GRAVEL BORDER
Weed area and ideally place porous fabric (Mypex/landscpae fabric) down;
Pin fabric down at edges, place plants out where desired, and adjust;
Cut slits in fabric and plant through it;
Top dress with gravel;
*If fabric isn't used, gravel will need topping up as it will sink into soil over time. Keep an eye on weeds for first few years.
98
Define: Rock garden, Scree garden, Gravel border.
Rock garden:
Classic rock garden with rocky outcrops, creating strata.
Scree garden:
Created on gentle slopes. Don't typically have large rocky outcrops of a rock garden.

Whatever it is, it needs adequate drainage holes!
100
Planting up rock/alpine containers
Cover drainage holes with crocks/gauze to prevent growing media washing out the bottom;
Growing media s/b free-draining - general mix is fine for containers;
Add slow-release fertiliser to media;
Fill trough with media and place any desired rocks, firming as you go;
Position plants, remove from pot and tease out roots - plant, being careful not to bury leaves or crown;
Water in and top-dress with layer of gravel.
*NB - think carefully about position of container - once planted up it will be very heavy.
101

Deadhead / remove dead leaves or plantlets in rosette-forming species - keep tidy!
For very small plants, use tweezers!
Water if necessary - prolonged drought - and thoroughly if you do! - let water soak deep into soil.
Autumn:
Hand weed
Continue deadheading and tidying
Trim to keep plants compact - light pruning with scissors
Replace / replant any plants past best
Mulch with grit to cover any bare patches before winter.

- light rolling, periodically
- aerate periodically
- repair lawn edges
- towards end of spring, apply a balanced fertiliser
SUMMER:
- mow regularly - maintain lower cut heights
- water during dry spells
- aerate periodically
- do NOT install lawn seed in summer months
- ONLY install turf if conditions allow - avoid extreme dry periods.
- control leatherjackets - re-check and apply additional treatments (July to Sept.)
- August is last chance to apply N-rich fertiliser
- apply "feed & weed" to allow grass to strengthen before Sept scarification
- apply fungicides/pesticides if necessary
- prepare seed beds for Sept sowing/turfing
AUTUMN:
- control weeds & pests
- assess for fungal diseases
- treat fusarium patch disease (Sept to Nov)
- Sept is last chance to control leatherjackets
- if moss is a problem, apply moss killer 2 weeks before scarifying
- apply fungicides/weedkillers/pesticides as required
- reduce mowing frequency and raise height to autumn cutting heights
- seed / turf new lawns
- apply autumn fertilisers, high in K
- carry out aeration using solid or hollow tines
- scarify vigorously and apply generous top dressing
- over-seed renovated areas
- cut if required, reduce frequency, maintain autumn cutting heights
- rake off leaves and debris
- overhaul equipment

Annual pond maintenance (by season)
SPRING:
Fish
- feed when returning from dormancy and seen more active in pond.
Equipment
- reconnect electricals (pumps and fountains) once frost has passed.
Plants
- stock with new plants from LATE spring (after frost risk)
- feed established plants (packet or solid mass fertilisers)
- divide any plants too big for pond
Cleaning
- remove dead leaves (floating and submerged) and other organic matter
- deadhead flowers and remove debris
SUMMER:
Fish
- continue to feed as required
Plants
- deadhead and remove debris
- thin out excessive growth of oxygenating plants
Cleaning
- remove blanket weed (long cane or rake). Leave material at side for a day so critters can crawl back
- in large ponds, barley straw can be used to suppress algae. Place straw bale in pond (in netting) and leave for summer.
AUTUMN:
Equipment
- disconnect electricals (pumps & fountains) before frosts set in
- clean equipment if possible.
- set up pond heater, if using.
Cleaning
- remove any organic matter you can (fallen leaves from bottom, cut back floating plants and vigorous marginals)
- keep area around pond tidy of fallen leaves from nearby plants
- net can be put over surface BUT consider wildlife access (birds and mammals)!
- can do water change (20-25%) to keep water healthy for fish and plants in dormancy
- if pond has stagnated or has severe algal problems, do a cleanout and complete water replacement.
WINTER:
- relatively quiet!
- if water freezes, melt hole (don't break)
- remove some water so level is no longer in contact with ice above, to prevent re-freezing
- pond heaters or water features with moving water, can be installed to prevent freezing.
