April: |
April
1st: Waking up after winterAfter the cold (should I say "normal") winter we were half
expecting plants to be late. None of it. Plants awoke after a proper
winter rest ready to perform and many including Centaurea (like Joyce,
right) and Geum were
earlier than usual. Centaurea
are already in full bloom with C. cheiranthifolia a star plant in the back
garden. They will bloom until June - July when they can be cut back for
more flowers in Aug - Oct. (Actually
they went right on blooming until October - Martin Oct 09) |
April
2nd: Brazen Hussey!
Christopher Lloyd had a way with naming
plants with a particular favourite being Ranunculus "Brazen Hussey" with bronze foliage and bright yellow
flowers.
Beware that they are invasive and the tiny bulbules will root and
take hold wherever dropped! Once flowering is over they disappear below
ground so we plant them under deciduous shrubs. |

3rd: Garden Tasks
We are continuing to divide plants.
Heleniums are still fine to divide as are Asters, Boltonia, Kalimeris. Its
good now to divide plants with a woody or rhizomous rootstock like old
world Salvia, Hemerocallis, Kniphofia.
Phlox can be divided but its a bit
late if you want perfect flowers this year.
With the latter I find its best to
pot up divisions and grow on under glass or a cloche. In the open they
tend to rot off.
Its also a good time to move
herbaceous plants.
We take some care to protect hardy
plants whose foliage is damaged by late frosts (i.e. they aren't killed
just set back). These include Persicaria Red Dragon and Maclayea. We
put a plastic bag or sheet of garden fleece over the plants on frosty
nights. Flower buds (of e.g. Camellia) can also be damaged and it is
advisable to plant these where they don't get the morning sun as rapid
defrosting will cause damage.
We don't start mulching yet as the
ground is not warm enough.

April 5th Pest Watch
Continue to watch for slugs
Watch Day Lily (Hemerocallis) buds twice a week and
remove any that swell at the base. This is sign of Gall Midge and if left
it can destroy all the flowers but if nipped off early nearly all flowers
will develop. Bag up the buds, seal and dispose of in the bin or burn the
buds. Do not drop or compost.
In dry spells greenfly multiply before their natural predators
are active. Rub off or spray in the evenings.

7th New Growth
Many herbaceous perennials are well into
growth now and one of the loveliest as it pushes through the soil and up
into the light is Phlox
paniculata Starfire with its red-bronze leaves and stems. |
April
11th Hellebore seedlings
Hellebores self seed really well
including the sun lovers like x.sternii. This is a seedling
from that hybrid with its pale green flowers and spiky-edged glossy
leaves. The seedlings gradually revert to a form more similar to one their
parents H.argutifolius.
I find it best to let them self-seed
rather than saving seed and sowing in compost. They can take a year or so
to germinate and are quite slow growing as seedlings.

12th Acers in Flower
I've never really looked at our Acer
davidii Serpentine in flower before but today I noticed the tiny
pink-green flowers and larger pink bracts along the stems.

13th Dorothy Clive Garden Plant Hunters' Fair
What a lovely day we had at The
Dorothy Clive Garden Plant
Hunters' Fair today. We organise the fair for the charitable trust
that runs the garden so we were a bit apprehensive as to the weather and
whether people would come out to support the fair. We need not have
worried as over 2000 people came along to provide welcome funds for the
garden and choose from a great selection of plants from some of our
nursery friends. Talking after the event with the curator, Marcus
Chilton-Jones we've agreed to hold the event over two days (Easter Sunday
and Monday) next year. We are already looking forward to the August
Bank Holiday plant fair at the garden. Both events make a great day out
with 12 acres of wonderful gardens and a fabulous plant fair. |
April
18th Geum Bell Bank
One of our favourite Geums is Bell
Bank which was introduced by Geoffrey Smith that great Yorkshireman
and gardener.
It is fully double and a lovely shade or
pink with a wide boss of yellow stamens. |

April
Alchemilla
mollis is one of those plants most of us grow that fades into the
background, quietly doing its job. We sometimes notice the pools of dew
that form on the leaves, but have you ever wondered why and how they
form.
One of our sons is studying the Superhydrophobic
properties of plant leaves for his doctorate in theoretical physics and
apparently droplet formation is not just due to a waxy surface but to the
microscopic arrangement of hairs on the leaves which prevent the water
molecules from spreading and hold them as droplets. The research will have
many practical applications such as improved non-stick surfaces. |
