Calendar of Garden Work for June

ONCE June is in, the fear of frost is over, even in the colder parts of the country, and everything should be growing well. The object of good cultivation is to keep both decorative plants and vegetables growing at an even rate. Feeding with fertilizers or liquid feeds is important during the summer months, as is constant vigilance against insect pests, diseases and weeds.

DECORATIVE GARDEN

The seedlings of wallflowers, Siberian wallflowers, forget-me-nots, honesty and Canterbury bells sown in May can be thinned to about 6 in. apart, preferably in two operations. The seedlings from the second thinning, if planted out in a freshly-prepared bed, will provide extra plants.

Remove dead flowers from lilacs, rhododendrons and azaleas.

Sow seeds of perennials in rows about 9 in. apart and thin the seedlings later. Choose a good nursery bed so that the plants get a really good start in life.

The seedlings of half-hardy annuals will have been hardened off in preparation for planting now, or they can be purchased in boxes from the local nurseryman. If a dry period follows the planting, take great care of the young plants until they become established.

Mulch border plants, especially phlox and Michaelmas daisies, and continue hoeing among all the plants in the border.

Lift late-flowering tulips and heel them in until the foliage has turned a creamy-yellow and then lift and store.

Prepare hanging baskets for putting out-of-doors, even in cool positions. Line each basket with polythene in which a few holes have been punctured, then line thoroughly with sphagnum moss before planting up with such plants as pelargoniums, lobelia, nepeta, fuchsias and marguerites. Use John Innes potting compost No. 2. Hanging baskets need careful watering as they dry out quickly, though with a polythene lining they will hold the moisture better.

Continue to keep a vigilant watch for aphids, black spot and mildew on roses, and mulch all types early in the month with old manure or well-rotted compost. Avoid using lawn clippings alone.

If plants are watered, water them really well. Light watering encourages feeding roots to form near the surface, which is not desirable.

Remove suckers from roses as low down as possible.

Lift and divide pyrethrums during the latter part of the month.

VEGETABLE GARDEN

Continue to sow seeds and work with the hoe among the rows of vegetables. Lettuces, peas, beet, radishes and spinach sown in May will be ready for thinning in two stages.

In all districts, ridge cucumbers, mar-rows, cauliflowers, savoys, broccoli, french beans and runner beans can be planted out-of-doors.

Plant out leek seedlings towards the end of the month in holes 6 in. deep in rows 1-1/2 ft. apart with 6 in. between the plants in the rows. Make each hole with a dibber, sufficiently deep to take both plant and roots without any cramping. Drop the young leek plant into the hole and water in. Do not fill the holes with soil or firm round the plants with the foot.

Tomatoes can also be planted out-of-doors in all districts. Prepare the ground well and choose a sheltered spot. Drive in a stake before each plant is turned out from its pot. Keep the ball of soil round the root intact. Plant at the base of the stake then firm well and tie gently with garden string.

Plant out celery, keeping a good ball of soil at the root of each plant, and water the plant in very well. Celery is a gross feeder and also likes plenty of moisture. Spray the rows with malathion to combat the celery fly. Once the plants are. Established give a liquid feed.

Earth up potatoes and spray with Bordeaux mixture against blight. At the end of the month the first early varieties should be ready for lifting.

Finish cutting asparagus at the end of the month, or two weeks earlier in early districts, to give the plants a chance to build up their crowns for next year.

Remove any flower heads that appear on autumn-sown onions.

FRUIT GARDEN

Spray raspberries with a proprietary spray containing derris against the maggot of raspberry beetle which eats into the developing fruits.

Mulch wall-trained fruit trees.

Watch for signs of reversion in black currants (spread by big bud mite). Remove and burn affected plants.

If necessary, carry out a final thinning of apples and pears at the end of the month.

Thin plums when they are the size of acorns. If there is still a heavy crop later in the month, support the branches with poles or posts.

GREENHOUSE

Leave the ventilators fully open now, but early in the month guard against sudden falls in temperature at night.

Damping down is important as outside temperatures rise, and direct shade may be necessary for some of the young rooted cuttings taken in May, and for the primula seedlings that are now in separate pots.

Water all pot plants daily, preferably in the morning, except those which are resting, such as nerines and lachenalias.

Make further sowings of primulas.

Fumigate the house with smoke pellets to control white fly where it appears.

Pot on into larger pots rooted cuttings of perpetual-flowering carnations and chrysanthemums.

Move zonal pelargoniums into their final 6in. Pots before placing them outside for the summer months.

Move winter-flowering begonias into larger pots, as necessary.
