The middle or the end of May is an exciting time in gardens, because we then bring out our half-hardy plants. Dahlias, delicate annuals, and bedders are all put into the borders when the early May frosts are over. If possible, this should be done in showery weather. Two or three dull, damp, warm days save a gardener a deal of trouble in shading and watering at this time of year. In case the weather is fine and dry, however, remember that a great deal can be done by planting each plant in a little puddle of water and shading it with a flower-pot or a box, or any little tent you can invent. When the nights are warm these coverings can be removed at sunset and replaced in the early morning. You will have to judge in each case how many days of such care a plant requires. When its roots are well established, it will look after itself by day as well as by night. You know, of course, that plants must never be watered when the sun is on them. Nevertheless, if ever you see a plant flagging badly in the sun, and plainly dying for a drink, you may give it one carefully at its roots. Do not let the water touch its leaves, and, if possible, shade it for the rest of the day. A great many biennial and perennial seeds are sown in May, for a gardener must work for the years to come as well as for the present one. It is a good plan to try to grow one biennial and one perennial every year, as two boxes of seedlings do not give you too much work. Be sure to get your seed at one of the best places, for nothing is more disappointing than to take great pains with inferior seed. Look carefully at your Rose-trees every day this month, and remove any leaves that are curled and stuck together. Each one contains a grub, that will become a caterpillar and devour the foliage of the tree later on. Leaves that are merely curled by cold, and not stuck together, must not be picked off. Convolvulus seed may be sown in the open this month. JUNE. Many plants will now require staking. We have told you how this should be done at the end of the chapter on ‘Hardy Perennials.’ Towards the end of the month you will find the leaves of Crocuses and Snowdrops quite dead, so that you can remove them without injuring the bulbs. At the beginning of the month you can still put out bedding plants, half-hardy annuals, and biennials. A plant may be put into the open ground out of a pot at almost any time of the year. It is the safest way of transplanting in hot weather, but you must distinguish between plants that have been honestly grown in pots and those that a nurseryman has potted from boxes a day or two ago. When the soil falls away and leaves the root and stem quite bare, your plant will want care and shade as much as if you had just pulled it out of a box yourself.
