April is an ideal month for attending to any existing lawn care issues which may have arisen over time. If
it is a newly laid lawn which is desired then now is advisable before the average temperature begins to increase. For the first cut of the year it is recommended that the setting of the lawn mower should be on a higher setting. This is known as the ‘one third rule’ meaning one must not cut more than a third off the length of the blade of grass in one go. Cutting shorter on the first cut can stress the grass and if cut too short and scalping occurs, then a bare patch would be inviting for weeds to grow. Towards the end of the month the cutting height can be reduced to achieve the eventual desired length, however, this is dependant on the weather conditions and if the grass is growing profusely then more cuts maybe required or the cutting height may have to be reduced earlier. Before the first cut is made, an overall inspection should be made of the lawn and with a grass rake in hand, rake as much of the lawn area as possible. This is to achieve clearing the lawn of any stones or debris which may damage the blades of the mower, it also lifts the grass blades signalling them into life, removes any unwanted thatch and an opportunity to observe any bare patches or areas where weeds are making an appearance. Aeration is advisable too, particularly in the areas which are susceptible to compaction and this can be carried out with a standard gardening fork, the numerous holes allow the root zone more access to air and water and the chance for the lawn to breath. Aeration also aids in controlling the unwanted thatch which hinders lawn growth. The key for mitigating weed growth is to eliminate the bare patches of lawn, if the grass is thick and lush the weeds have less chance of growing. One must ask why a bare patch exists and does it occur in the same area each year, this maybe due to the area having minimal sunlight such as under a tree canopy. If this is the case then it maybe worthwhile considering reducing the lawn size and create a shallow garden bed for small shade tolerable plants. Where there are other bare patches of a noticeable size the ground can be prepared for ready made rolls of turf or alternatively grass seed can be applied. Preparation is of the utmost importance here and watering after the turf has been laid or the seed has been sown is essential. With the possibility of having more time available, then those deep rooted dandelions, providing they are not too in abundance and the ground reasonably soft could be dug out by hand. It is the bane of the lawn lover, but the dandelion with its bright yellow flowers is beneficial to pollen beetles and bees particularly in the month of April, therefore, if desired the first cut could always be delayed. It should be considered too that if the lawn was to remain slightly longer throughout the year, cut on a higher setting, then this may result in less weeds. The greater surface area on an individual grass blade equates to increased photosyntheses, which then results in more growth and increased root system, hence reducing the space for weeds to grow. by Oliver David Cook on behalf of Green Landscapes Cornwall

MARCH FOR THE SUMMER BULBS During the month of March the northern hemisphere spring equinox occurs, thus the length of daylight is equal to that of darkness. From then onwards the daylight hours increase and the gardening season is well and truly upon us and no doubt a floriferous spring and summer to look forward to. A variety of summer bloom can come from the bulbous plants and the month of March is ideal to plant the following popular bulbs: - Dahlias - Gladioli - Begonias - Crocosmia - Cannas Lily All of the above can be regarded as sub-tropical plants, which thrive in the sunny and warm locations of the garden. Therefore, it is best to take heed of the weather forecast and not to proceed with planting if a frost is imminent. Essentially the difference between spring bulbs and summer bulbs is that the spring bulbs require several weeks of cold temperatures to trigger the upward growth, hence they are planted in autumn and remain in the soil throughout the winter with growth and blossom occurring in spring. However, the summer bulbs with their preference for a warmer climate do not require this slumber period of cold temperatures. The term bulb is used generically as it includes bulbs, tubers, corms and rhizomes. They are all underground storage organs, the correct name which classifies them all under one umbrella is ‘Geophytes’ originating from Greek, earth (Geo) and plant (phytes). The planting depths can vary depending on the type of bulb, a good rule of thumb is two to three times the size of the bulb which more than often equates to planting approximately 100mm deep. Dahlias are root tubers and can benefit from being pot planted in a greenhouse for the initial growth to commence and then transplanted into the garden, this is to ensure they do not succumb to any frosts. It is however, the temperature of the soil, a minimum of 13c and not the air temperature which contributes to healthy and beautiful dahlias, therefore, it is best to choose an area with full sun and lighter, free drainage soil. Gladioli and Crocosmias are both corms and to be planted approximately 100mm deep and it is advisable to prepare the planting bed by adding some compost after loosening the soil with a garden fork. The Crocosmia corms will benefit from being planted in clumps, whereas, the Gladioli should be planted individually with the point of the corm facing upwards and by placing several in close vicinity to one another, one will be rewarded with a fabulous display of blossom. Gladioli also make excellent cut flowers for the enthusiastic florists amongst us. Begonia tubers are suited for containers and hanging baskets and will provide a continuous colour throughout the summer and autumn. The fibrous rooted variety are more suitable for the garden beds. The tubers have a convex side which is planted downwards, the concave side will posses the new growth and faces upwards. Plant in a pot with a thin layer of gravel/shingle to allow for drainage then the remainder with compost and plant the tuber just beneath the surface. The range of colourful begonias available ensure hanging baskets are a great addition to any garden. The canna lily is a rhizome (underground stem) and the large bold tropical leaves and striking flowers make for a terrific display and should be planted in full sun and a sheltered location away from strong winds. Plant the rhizomes, with the growing points facing upwards, 100mm deep with 500mm spacing between each one for a superb summer display and then water thoroughly. It is highly recommended to use a soil thermometer probe before the planting of summer bulbs, then one can be sure the necessary soil temperature of 13c has been reached for a successful summer bloom. |
