d. April: Perth Gardening

This is my personal growing calendar for Perth conditions during the month of April.
The main calendar page is here and explains why I am doing this and what you can expect.


Still warm but beginning to cool some with daily maximums in the mid 20C. Rainfall is supposed to be double that of March. All this calls for a change in what and where we plant.


  • artichokes
  • asparagus
  • beetroot
  • broccoli
  • brussel sprouts
  • cabbage
  • cauliflower
  • chrysanthemums
  • garlic bulbs – thanks Ben and Jean Davis for your tips, apparently you refrigerate the bulbs for about a week to improve germination success. You best get a wiggle on though!
  • kale
  • leaf beets (perpetual spinach)
  • leeks
  • marigolds
  • mizuna
  • nasturtium flowers
  • onions
  • parsnip
  • peas
  • potatoes
  • radish
  • snow peas
  • spinach
  • spring onions
  • swede
  • tomatoes – cherry
  • turnips


My star performers:

  • bhut jolokia peppers
  • cayenne peppers
  • coriander
  • leaf beets (perpetual spinach)
  • limes (common)
  • radishes

My strugglers:

  • beans – I think because I didn’t replenish their soil’s nitrogen enough after a very bountiful crop.
  • jalapeño peppers   – I think because I didn’t replenish their soil’s nitrogen enough after a very bountiful crop and fungus took control. Sprayed lime sulfur and we are back in business.


  • if asparagus fronds are yellowing (they really should have already), trim to 2 cm above the ground
  • keep an eye on mildew etc as the warm weather and rainfall are perfect conditions
  • make snail traps
  • keep weeds to a minimum, the rainfall can lead to weed explosions
  • add 1.5kg of Dynamic Lifter Fruit Blend to each large citrus plants (follow the product’s instructions for younger/smaller trees or those in pots)
  • slow feed your roses for the coming ‘chilly’ weather and watch for pests
  • preserve chilis by freezing, pickling and drying
  • care for your chilis by spraying with pyrethrum to keep grubs at bay


  • harvest any asparagus.
