JOUHNAL  OF  HORTICULTURE  AND  GOT TAUE  GARDENER. 
Ipril  10,  1902. 
preparation,  as  free  growtli  is  desirable  after  planting.  Any 
senous  check  will  result  in  stunted  plants  and  the  appearance  of 
mildew,  with  the  consequent  failure  to  properly  flower.  To 
avoid  this,  have  a  rich  moist  root  run,  give  surface  cultivation, 
and  mulch  the  rows  in  summer.  Immediately  after  planting  out 
a  row  of  Peas,  draw  some  earth  on  each  side  the  rows,  and  at 
once  place  the  sticks  to  them,  both  as  a  support  and  protection 
against  cold  winds. 
SEAKALE.— In  order  to  forward  the  growth  of  Seakale  out^ 
doors  cover  the  crowns  with  ashes,  or  pots  may  be  employed 
having  a  moveable  top  or  lid.  The  thongs  or  roots  that  were 
preserved  from  the  forcing  crowms  in  winter  are  now  cominenc- 
grow’th,  and  should  be  planted  on  a  previously  prepared 
piece  of  ground.  The  roots  may  be  placed  a  foot  apart  in  rows 
2ft  asunder,  or  if  preferred  plant  in  a  triangular  clump  each 
■  clump  being  at  least  2ft  apart.  Where  a  stock  of  Seakale  must 
be  raised  from  seed,  the  present  is  a  suitable  time  to  sow  the 
seed.  This  may  be  sown  in  rows  a  foot  apart,  ultimately  taking 
-  out  every  other  row  and  planting  elsewhere.  Thin  out  the  seed- 
'  ungs  well,  12in  apart  not  being  too  much. 
.  PLANTING  POTATOES. — No  opportunity  ought  to  be  lost 
in  ord(w  to  plant  out  the  stock  of  Potatoes  as  soon  as  possible 
now.  The  whole  of  the  late  varieties  may  be  completed  planting 
when  the  soil  is  friable.  Early  Potatoes,  furnished  with  strong 
sprouts,  which  they  have  been  encouraged  to  produce  by  standing 
them  on  end  in  boxes,  should  be  planted  as  favourable  times 
permit.  Draw  drills  6in  deep,  placing  the  sets  in  them  at  a  foot 
apart,  the  drills  being  2ft  asunder.  Cover  carefully  with  a  light 
rnixture  over  the  sprouts,  so  as  to  protect  them  well  from  any 
sharp  frosts  which  may  occur,  and  from  time  to  time  draw  dry 
soil  around  the  tips  as  they  protrude  until  danger  from  frost  is 
past. 
SOWING  PARSLEY. — A  plentiful  supply  of  Parsley  should 
be  sown  in  drills  or  broadcast.  It  is  often  verj^  convenient  to 
'have  a  long  row  sown  by  the  side  of  a  walk.— East  Kent.

*■**  All  correspondence  relating  to  editorial  matters  should  be  direoted 
to  “  The  Editor,”  12,  Mitre  Court  Chambers,  Fleet  Street, 
London,  E.C.  It  is  reciuested  that  no  one  will  write  privately 
to  any  of  our  correspondents,  seeking  information  on  matters 
discussed  in  this  Jouimal,  as  doing  so  subjects  them  to  unjustifiable 
trouble  and  expense. 
COS  LETTUCE  IN  THE  MARKETS  (J.P.).— The  Cos  Lettuce 
handled  by  you  in  the  market  would  no  doubt  have  come  from 
greenhouse  culture.  Even  Cabbages  are  groum  under  long  span- 
roofed  houses  in  some  of  the  London  market  gardens.  Frame 
culture  is  more  prevalent,  hmvever. 
VINERY  AS  A  GREENHOUSE  (A  Constant  Reader).— Your 
house,  having  no  sun  in  the  afternoon,  will  answer  better  as  a 
greenhouse  than  as  a  vinery,  and  will  be  useful  for  growing  plants 
for  the  conservatory.  It  will  need  but  little  in  tlie  way  of  altera/- 
tion.  The  Vines  will  have  to  be  taken  out  and  stages  provided. 
We  suppose  it  is  heated  sufficiently  to  exclude  frost. 
INSECT  TO  NAME:  IS  IT  DETRIMENTAL  OR  HARM¬ 
LESS.*^  (H.  M.  W.). — The  insect  is  a  mite  of  the  section  Trom- 
bididse  (harvest  mites),  according  to  Koch  and  Andrew  Murray, 
though  some  regard  this  as  an  error,  and  refer  it  to  Tetranychidse 
(spinning  mites).  It  is  named  Bryobia  iirmtiosa  or  B.  specio.sa, 
for  there  is  no  difference  in  the  tw'O  only  in  name.  It  is  com¬ 
monly  known  as  Ivy  red  spider,  and  often  swarms  on  Ivy  in 
gardens,  especially  that  against  walls,  and  seems  to  roam  abput 
in  the  spring  and  early  summer,  often  being  found  on  many 
plants  and  in  many  places  at  that  time.  In  1893  it  was  found 
seriously  affecting  Gooseberry  bushes,  causing  considerable  loss 
in  many  localities  to  growers.  It  chiefly,  however,  infests  Ivy, 
which  is  sometimes  greatly  disfigured  by  its  attacks  on  the  leaves, 
as  it  sucks  their  juices  and  stunts  their  growth.  It  may  be 
destroyed  by  spraying  with  petroleum  softsoap,  2oz  to  a  gallon 
of  water,  or  carbolic  soap,  loz  to  a  gallon  of  water.  The  under 
side  of  the  leaves  as  well  as  upper  must  be  wetted  wdtli  the  solu¬ 
tion,  either  by  spraying  or  syringing  upwards. 
CLIMBING  PLANTS  (A  Climber). — We  surmise  that  the 
cement  walls  of  the  house  you  wish  to  cover  are  not  in  any  way 
wired  or  have  a  latticed  framework  against  them.  Were  there 
either  wires  or  such  a  frame  as  we  refer  to  you  could  train  up  a 
large  number  of  suitable  ornamental  climbers,  such  as  Clematis 
in  variety,  Roses,  Honeysuckle,  Wistarias,  Forsythias,  Cydonias, 
Smilax  rotundifolia,  Jasmhium,  Halesia  tetraptera,  Periploca 
grseca,  Magnolias,  Indigofera  decora,  Vines,  and  many  other 
plants  besides.  Without  any  support  whatever  we  know  of  only 
Ampelopsis  and  Ivies  that  will  climb  and  cling  firmly  by  natural 
means.  Choosing  the  small  leaved  forms  of  each,  these  are  very 
beautiful  and  useful  plants.  Ampelopsis  (or  Vitis,  to  be  pedanti¬ 
cally  accurate)  inconstans,  otherwise  named  A.  tricuspidata  and 
A.  Veitchi,  is  very  generally  used,  as  also  the  Virginian  Creeper, 
Vitis  (Ampelopsis)  quinquefolia,  wdiich  has  a  number  of  varieties 
that  differ  slightly.  Of  Ivies,  the  following  might  be  chosen: 
Hedera  Helix  chrysocarpa,  cuspitdata  minor,  deltoidea,  gracilis, 
marginata  aurea,  Maderiensis  variegata,  and  others  whose  names 
are,  however,  more  or  less  confused  in  catalogues. 
VENTILATING  CUCUMBER  HOUSES  (F.,  Wiltshire).— 
In  dull,  mild  weather  wm  do  not  advise  Cucumber  houses  to  be 
kept  close  and  temperature  down  to  75deg  by  reducing  fire  heat, 
but  have  found  it  better  to  keep  a  fair  amount  of  fire  going  and 
maintain  the  temperature  at  70deg  tO'  75deg,  giving  a  little  air 
at  75deg,  if  tliat  point  is  reached  early  in  the  forenoon,  and 
then  only  a  moderate  amount,  without  giving  rise  to  an  inrush 
of  cold  air  or  in  any  degree  lowering  the  temperature.  This  will 
allow  of  a  change  of  air,  and  the  plants  will  be  benefited  in 
constitutional  vigour,  not  being  in  any  ivay  prejudiced  in  the 
swelling  of  the  fruit  or  in  steady  progressive  groivth  of  plant. 
The  houses  should  be  closed  early  in  the  afternoon  when  air  is 
admitted  early  in  the  da3q  as  after  a  change  of  atmosphere  the 
plants  profit  considerably  by  a  moiist  atmosphere  and  relatively 
liigh  temperature  ;  but  it  is  not  desirable  to  maintain  a  tem- 
peratura  of  more  than  7Udeg  to  75deg  by  day  in  dull,  mild 
w'eather,  as  the  evaporation  is  not  great,  and  a  higher  tempera¬ 
ture  induces  a  relatively  attenuated  growth.  Unquestionably 
ventilating  rather  more  than  is  usual  under  the  present  system 
of  growing  Cucumbers  for  market  is  one  of  the  best  means  of 
avoiding  the  diseases  to  which  Cucumbers  are  liable,  especially 
those  of  a  fungoid  nature,  especiallj'  when  a  little  sulphur  is  kept 
on  the  hot-water  pipes.
