Birds are more plentiful this month. They’re singing, mating & nest-building. I like to clean & refill birdbaths. It’s also nice to provide some nesting materials seeing as how I’ve already composted much of the natural material over winter.
- Sharpen pruners, shears and hedge clippers and make sure they’re free from rust.
- It’s best to clean pruners between each shrub. Spray with a solution of 10% bleach & water. This helps to prevent the spread of diseases through the garden.
- fruit trees – before the blooms open, apply dormant oil to control pests (unless it was done in February)
Hydrangea should be pruned after the middle of March to avoid die back from freezing winds.
- The common butterfly bush blooms only on new growth, so If it wasn’t cut it back to a manageable size in the fall, now’s a good time to prune it to the shape that suits the setting it’s in
- Roses can be pruned when the forsythia is in bloom.
- Forsythia & other flowering shrubs can be pruned right after flowering.
- add compost or sea soil to areas of heavy feeding, like rhubarb, asparagus patch & veggie bed
Plant summer flowering bulbs (gladioli & lilies) towards the end of the month, depending on the soil conditions. They don’t like sitting in waterlogged soils.
- Sow sweet peas and hardy annuals such as alyssum, & calendula.
- As the temperature increases so will growth. This is when that January mulching really starts to pay off. Wander through the beds digging out the occasional perennial weeds (dandelions…) If the mulching didn’t happen, keep a check on the carpet of young weeds & remove them before they take hold… Pop weed goes to seed quickly, so get rid of it fast!
- The worst of the cold is past now & the birds have more choices for food. Now’s the time to cut back the perennials left standing for the birdseed… Tall sedums blooms are a good example. Isn’t it nice to see the new growth at the base is already showing?
Now’s also the time to finish up dividing those overgrown hardy perennials:
- Cut the tops back to a couple of inches.
- Lift the whole plant out with a fork.
- Look for a natural line across the plant and cut it with a sharp knife right through.
- Continue this until you have divided the plant up to suit your needs.
- Replant the pieces in groups of 3-5 to make an impact in ornamental borders from repeating colour schemes.
- Pot up spares immediately.
- Water well.
- Edge the beds & lawns now, slicing the grass runners that are trying to invade the garden.
The grass will be growing steadily now,
Make sure the mower is serviced and ready for the season.
- Before mowing, remove thatch and moss by scarifying with a lawn rake.
- Set the blades to a higher setting (3cm) for the first few cuts.
- Stay off or try to minimise activity on the lawn if it is wet. It will turn to mud very quickly in the wet.
- Re-seed any bare areas: scratch the surface with a lawn rake and sow.
Veg & Berry Patch
- Get into the raspberry patch & take out the spent & spindly stems. Tidy up the bed & tie this year’s producers to the trellis.
- starts – Direct seed arugula, broad beans, corn salad, kale, chard, spinach, oriental greens and peas outdoors.
Greenhouse & Cold Frames
- Buy seed potatoes now and store the tubers in a light, cool (10°C), frost-free spot and leave them to sprout. (This is called chitting.) Egg cartons make good chitting trays. Make sure to put the tubers with the ‘eye’ end ( where the sprouts will grow from) upwards.
- starts – asparagus, broccoli, cabbage, cauliflower, leeks, lettuce, peppers, eggplants… start tomatoes later in the month
Watch for ‘damping off’ disease in seedlings in the greenhouse or indoors. This fungus causes the stems to collapse and the seedlings to fall over.
- Avoid over-crowding seeds & sprouts. It’s better to have a tray of fewer, healthy plants than to lose many to this disease
- Water often, but sparingly
- Ensure that seedlings get enough light to prevent them becoming ‘leggy’.
- Turn seed trays daily to ensure even growth.
Remove fallen leaves and other decaying plant debris from ponds. Frogs and other aquatic life will be emerging from winter hibernation so a good tidy up now prevents stagnation & algae build up.

Planning & Events
- The Victoria Orchid Club hosts its spring show (usually the first weekend in March)
- Garden shops are opening up for the season, so it’s fun to cruise them for ideas, but most of their early starts aren’t ready to go out into the garden yet, so control yourself (unless you’re up for nursing those babies inside for another month or two).
