What to do in May


Now’s the time to plant frost-hardy trees, shrubs and climbers.

Their roots are still able to develop into the surrounding soil
although the process may be slower. The advantages of planting now,
is that the ground does not dry out quickly, less watering is
practised, and by spring the plants have established their roots and
well on their way for rapid growth in the warmer weather.

It is still time to plant winter bulbs, especially the Tulips.

If your perennials are overcrowded, it’s now the time to lift and
divide them. Otherwise a good spread of compost and fertilizer high
in potassium (k) is ample.

Start preparation against frost, mulching with compost ± 10cm thick or
using bark chips. This will protect the crown and shallow roots.

Fertilize your winter flowering annuals with 3-1-5 SR if they are
large enough and almost flowering. If they are still too small apply
2-3-2, work it in and water.

Don’t forget to water regularly your “all season’s evergreen”, “shade
over” or “falcon” grasses.

Watch out for signs of the “Italian Aphid” especially attacking the
side shoots. Use Complete and Meridian,
alternating at regular 10 day intervals.
