May Work in the Garden with Cousin Jack

Lawns:
Cultivate new sites for autumn sowing and leave rough during the summer. Established lawns:
Apply a high nitrogen fertiliser and continue regular mowing. Apply fungicides for disease control. Continue to apply weed killer.
Roses:
Spray regularly against green-fly using a systemic insecticide. Remove rolled-up leaves containing tortrix caterpillar or sawfly grub and destroy.

Dahlias:
Plant out young dahlias when danger of frost is past. Drive 5ft. stakes 12ins. into the ground and label each plant. Protect young plants with newspaper if the weather is cold.
Chrysanthemums:
Plant out garden-flowering varieties. Plant out pompons and koreans intended for garden decorative. Apply slug pellets under foliage and flat stones. Carefully fork the ground around the healthy stools, fertilise, water and reduce new shoots to six.
Gladioli:
Continue regular hoeing. Water plants thoroughly in dry weather.
Lilies:
Spray monthly with a systemic insecticide against aphids and fortnightly with Bordeaux mixture against botnytis. Watch for signs of basal rot and fusarium disease.
Sweet peas:
Hoe around the plants frequently. Mulch, the plants in dry weather. Tie cordons regularly as they grow.
Bulbs:
Remove dead blooms from daffodils and hyacinths. Lift daffodils and tulips from beds to make way for summer bedding. Weed rows of bulbs grown for cutting and water in dry spells. Plant crinum bulbs in a south-facing border or in tubs.
Trees and Shrubs:
Plant out shrubs that are ten-der when young, arbutus, choisya, fuchsia and hydrangea and keep well watered until established. Complete planting evergreens in showery weather. Keep newly planted shrubs moist at roots and spray foliage with water in dry weather.
Rhododendrons and Azaleas:
Pick off dead flowers. Water newly planted bushes in dry weather. Mulch with peat-leaf mould or proprietary forest bark.
Heathers:
Complete remaining planting. Mulch bare ground with peat or proprietary forest bark and top-dress older plants.
Fruit:
Watch for pests and control as necessary. Water fruit trees and bushes in dry weather while fruit is swelling. Bark ring apples and pears if necessary to encourage fruiting. Feed apples, pears, cherries, blackberries, loganberries, black currants, gooseberries, peaches and nectarines, plums, damsons, raspberries and red currants. Control weeds around trees and bushes grown in cultivated soil. Start thinning fruit on wall-trained trees. Vegetables:
Prepare sites for growing marrows and pumpkins outdoors; sowing and thinning the seeds later in the month. Prepare planting sites for outdoor tomatoes. Sow French beans outdoors. Make further sowings of summer spinach and salad crops. Sow long-rooted beetroot for storing for winter use. Sow runner beans and erect canes or poles to support them.

Herbs:
Make further sowings of chervil, dill, fennel, hyssop and parsley and thin out April-sown herbs.
Patios and Town Gardens:
Plant tender plants in containers after hardening-off. Complete sowing hardy annuals. Arrange containers on patios and erect supporting material for climbing plants. Lift spring flowering bulbs after flowering and plant in a spare corner of the garden, setting summer bedding plants in their place. House Plants:
Water all plants liberally from now until autumn. Give liquid fertiliser. Avoid standing plants in a direct draught. See that plants apart from succulents do not remain on south-facing window-sills at mid-day. Re-pot older plants as they out-grow their pots.
